A project by Ecodomus in Kaunas, Lithuania

Aspirations for a sustainable future are increasing in Lithuania. Timber has reclaimed popularity within the domestic market as the environmentally friendly material of choice.

Off-site timber frame manufacturer “Ecodomus” specialises in sustainable construction and has been commissioned to deliver a contemporary structure depicting minimalistic aesthetics, whilst achieving high operational energy efficiency.

To accomplish the objectives of the project the business has relied upon the use of DuPont™ Tyvek® membranes to the protect timber structure and create an airtight building envelope. The building is located in Kaunas and belongs to InMedica (www.inmedica.lt) which owns the largest chain of healthcare clinics in Lithuania.

Timber structure is protected by DuPont™ Tyvek® Soft membrane due to its outstanding weatherisation and hygrothermal performance.

By putting together the architectural brief for the design team, InMedica has realised its ambitious vision for a new multi-functional facility. The business wanted to pursue sleek contemporary aesthetics suited to accommodate a clinic of general practitioners’ along with other medical services offered. It is expected for the operational performance of the building to be highly energy efficient to reduce the carbon footprint, as well as to meet stringent and demanding requirements set for medical facilities on hygiene and healthy spaces.

The architect studio “ARCHAS” made a decision to commission the project to “Ecodomus“ – one of the fastest growing companies in the domestic market of engineered timber. DuPont™ Tyvek® StructureGuard breathable wall membrane was the material of choice for “Ecodomus“, due to its outstanding durability and vapour-permeable properties. Tyvek® StructureGuard is well renowned for its water repelling performance, providing long term protection for degradable structures such as timber. The architects have thoroughly considered detailing and have hence specified DuPont™ FlexWrap flashing tape to protect heads & jambs of windows and doors from unintentional air-leakage and water ingress.

“Use of timber speeds up the construction timeline while allowing us to pursue sustainable construction practice. We accepted the challenge to combine advanced technologies and vanguard engineering to achieve the objectives of our customers. We were happy having found a reliable solution to prevent ingress of water via the envelope of the building. We have therefore chosen Tyvek® membranes, which offer the highest environmental performance credentials with excellent 15 year product warranties. This has helped us exceed the regulatory requirements applicable in our country. Being satisfied with the solution, we would highly commend the product.” Quoted by Mr Girmantas Juknys, MD of Ecodomus.

One third of Lithuania’s territory is covered by forests, predominantly pine trees. Timber has been used as a locally sourced building material for centuries and the skills of the woodworking & joinery trade have been passed down through the generations. There are well known historical architectural masterpieces built from timber, but only very few have survived. Abandoned during the Soviet era, timber regained its momentum in independent Lithuanian architecture and is capitalised today to create pleasant, healthy, and sustainable living spaces.

Kevin Dodds, Delta’s Manging Director, shares some thoughts on structural waterproofing and ground gas protection approaches.

With much anticipation, BSI launch BS8102:2022 Protection of Below Ground Structures Against Water Ingress. Code of practice. Within the update is recognition of combining both structural waterproofing and ground gas protection.

Prior to the launch of BS8102:2022, both BS8102:2009 and BS8485:2015+A1:2019 were intertwined, however BS8102:2022 provides further and greater clarification on design approaches.

Awareness and a better understanding of the potential impact of ground gas is being recognised more and more by both industry professions and homeowners alike. Ground gases aren’t particularly something new, however newer technologies for dealing with ground gases are. With innovative new products, and approaches to design it’s possible to provide both a robust, continuous waterproof and gas proof design.

Ground gases either occur naturally or through human activity which impacts on environmental factors. From Radon to Volatile Organic Compounds (VOCs), the impact of ground gases on occupiers of a structure built on a contaminated site are substantial. From health issues to toxicity, ground gases should be approached with caution.

A desktop study is the first part of the site investigation process, depending on the risks present, these findings will contribute to determining the overall protection systems chosen.

If a site has been identified with ground gas or hydrocarbon contamination it will be given a Characteristic Situation Score. The Characteristic Situation Score is defined according to how severe the gas flow and gas concentration from the ground/soil is.

All sites which have been characterised with a gas situation score will require a gas protection system and where identified a waterproof protection barrier.

Ground gas protection is a barrier that prevents hazardous gases and contaminants from the underlying soils entering a structure. A well-designed system can also perform the function of a damp-proof membrane, assisting in preventing the ingress of moisture into the structure.

Waterproof protection is the prevention of water ingress into a structure. A well-designed system may also perform the function of a ground gas protection system (product selection pending).

Evaluation of groundwater conditions, risk assessment and options for drainage outside the structure should always be considered and included in the overall design.

A Waterproofing Design Specialist will be able to interpret the requirements of BS8102:2022 and BS8485:2015+A1:2019 along with other legislative documents to produce a waterproofing design which incorporates both a waterproof and gas proof protection system.

A key element of this design approach is a continuous solution. When we use the term “continuous”, we are referring to the design approach, which should include the whole structure (from detailing to any opening), ensuring the entire structure is protected.

We are always Happy to Help

Melius Homes (www.meliushomes.co.uk) is a building firm with a clear philosophy: build high quality, affordable, flexible new homes and transform existing dwellings into energy efficient, comfortable and healthy homes Rather than demolish structurally sound houses, Melius Homes re-skins walls and roofs with modern materials that provide greatly enhanced performance, protecting the occupants from the harmful effects of heat, moisture and air leakage. In order to achieve these goals and to be suitable for use in any location, Melius Homes specified a selection of DuPont construction membranes and accessories.

“With this project, we retain the existing building, and therefore it’s embodied energy. We encapsulate it to provide minimal air leakage, typically < 1m3/hr/m2. This is an improvement of greater than 90% over the building regulations and can be applied to almost any existing structure, whatever its type, across the whole of the UK.” said Paul Clark, Design Manager at Melius Homes.

On the wall panels warm side, DuPont™ AirGuard® SMART is incorporated as the AVCL and this provides a 100% airtight layer, combined with a controlled level of vapour resistance, in order to minimize convected heat losses. On the external, cold side of the Melius Homes panel, a W1 rated DuPont™ Tyvek® Reflex is fitted, and this means that not only can the panels be used in any exposure area, the uniquely lacquered, metallised surface, provides a protected low-e material, to permanently boost the performance of the insulation. DuPont™ Tyvek® Metallised tape is used to seal the membrane laps and maintain the systems thermal performance.

On the roof panels, a similar build up is employed, but here a layer of DuPont™ Tyvek® Supro underlay is used. Unrestricted when tested to BS5534 +A2 2018, Tyvek® Supro can also be used in any location in the UK, regardless of site location, height above sea level, proximity to water, site topography and ceiling condition. Adding to the convenience is the roll size – being 3.0 x 50m means minimizing overlaps which increases the speed of installation in the factory.

All buildings have penetrations and here, Melius Homes make use of DuPont™ Tyvek® Flexwrap EZ. The flexible nature of Tyvek® Flexwrap (a 1m length will stretch to 1.6m) makes it ideal for any sealing application, regardless of shape or size, with the need for separate grommets eliminated.

“We never seemed to have the correct size for the job! Tyvek® Flexwrap EZ means that all we need to do is cut it to length and this, in turn, means that there is no waste, an important consideration when constructing low carbon homes”, commented Paul Clark.

Quick and easy to install, the Melius Homes approach, and the Tyvek® and AirGuard® membranes and accessories that are used, ensures the best performance possible and utilises the best of both worlds – retained masonry construction for thermal mass and timber panels for maximum thermal performance and airtightness. This is vital because airtightness ensures that the system performs “as designed”, with virtually no performance gap, and keeps heating bills to a minimum.

About Melius Homes (www.meliushomes.co.uk) – Melius Homes brings years of experience to the challenge of creating a bespoke home with the consistency and reliability of a manufactured product. Their homes are built in a systematic and controlled way, with much of the fabrication undertaken in an enclosed factory environment.

This approach allows the firm to manage the construction and assembly processes with real rigour. Factory fabrication reduces the number of construction faults and improves the internal fit and finish of materials, built-in fittings and appliances in bathrooms and kitchens. The same approach is applied to the vital ‘hidden’ elements – the wiring, plumbing, heating and ventilation systems – that form an increasingly important role in new, low-energy cost homes.

As the name implies, cold applied liquid roofing/waterproofing is the use of a liquid waterproofing system without the requirement of heat.

Waterproofing roofs (whether it’s a flat roof or podium deck) is one of the most important structural requirements of any building. A watertight roof performs a vital function in protecting a structure.

When water starts to stand on a roof, not only can it lead to structural damages, it can also reduce the roof’s lifespan. In the roofing industry, ponding water refers to water that has stood flat on a roof for longer than 2 days following precipitation. Ponded water on roofs can also be a breeding ground for micro-organisms and other bacteria. This can be particularly problematic where the roof is protecting a hospital or school. Flat roofs are a regular feature on public and commercial properties such as schools, hospitals, leisure centres, warehouses and factories.

Liquid waterproofing systems or cold liquid roofing are a great cost-effective method for waterproofing both new and existing roofs.

Simple to install and long-lasting, there is little doubt that the introduction of liquid waterproofing has been one of the most innovating advances in the industry.

Cold liquid waterproofing is simple and ready to use, at once forming an effective barrier to water and humidity.

Due to cold liquid roofing’s easy to apply nature, it is suitable to a wide variety of uses. Applied with a simple brush, it easily allows reach to the almost inaccessible of areas, meaning that critical areas for the overall quality of the waterproofing are continuously and completely covered, guaranteeing the total protection for surfaces.

Benefits

Cold liquid applied roofing is significantly faster, safer and less labour intensive to apply than conventional roofing materials.

Cold applied roofing, requires no torches, burners, or other heating equipment during application, posing no fire risks. A cold applied liquid waterproofer cures to form an elastomeric waterproof membrane. Practically bonding directly to a substrate, providing a seamless, UV-stable continuous system, able to contour any roof shape for intricate detailing.

Why cold applied liquid systems?

Cold applied liquid waterproofing systems are engineered to supply a fast curing, long-lasting, flexible, elastomeric solution.

Other benefits include:

Excellent adhesion to all kinds of surfaces
Chemical resistant
High resistance to extreme temperatures
Completely seamless waterproofing
No heat or special equipment needed

Technical Drawings (Structural Waterproofing) – Delta Membranes

Product – Delta Membranes

Application – Delta Membranes

Overview
Waterproofing design is a key and critical component for successful construction of below ground structures. Whether it’s a completely new build or making smaller changes to an existing property, waterproofing design should never be overlooked.

Waterproofing might account for just a small fraction of a building’s total cost, but waterproofing defects can result in catastrophic consequences. When waterproofing fails, the implications are significant.

Delta’s MD, Kevin Dodds was approached to offer advice and guidance on a failed waterproofing system.

The existing structure had an impressive 5-level basement which houses: kitchens, food storage and food preparation areas, spa, plant rooms and accommodation. Near to a large river, the site sited well within the water table. The original waterproofing system was based on the secant piled walls and a block wall internally to provide a basic drained protection system with drainage holes at various points to drain to various levels.

Over time, the third floor had become completely saturated with all levels of the basement experiencing water ingress in varying levels from damp patches to significant “jets” of water and flows of water through the secant piles.

With remediation waterproofing design strategies, it may take some time to specify a suitable system. It is important that investigations are thoroughly carried out by individuals with the capability of diagnosing the defect, assessing the extent of that defect, and recommending a suitable corrective measure.

Methodology

Following preliminary site inspections, discussions were held on remedial options, methodology for remedial works and cost. During site observations significant water was sitting behind the corbel. This water could be entering the structure either: directly through the piles, from the floor above or from the joint between the soffit and piles or a combination of all three.

When designing a robust waterproofing remediation approach, attention to detail is critical.

Balancing costs with quality, method suitability testing was carried out on trial areas. A combination of resin injections and curtain injection were proposed prior to the installation of a Type C cavity drain membrane system to facilitate performance levels. Alternative combinations were suggested on two trial areas.

Firstly, the secant piles were exposed and thoroughly cleaned to remove dirt, salts, and loose particles. Whilst slow flowing leaks and drips could be sealed with resin injections alone, any fast-flowing water ingress was stopped in advance of injection works with the use of Koster KD Blitz 2.

Koster 2 IN 1 was injected into the corbel area with Koster IN 7 being injected into the vertical joints between the piles.

It was observed following inspections, over a 5-week period, that the corbel area was dry. Delta’s MD, Kevin Dodds suggested a further monitoring period, or until two periods of heavy rain to assess performance levels.

Phase 1

Following trials and analysis of approach, Kevin suggested the use of Koster G4 Gel as a curtain injection to areas identified after exposure works to each area, in combination with Koster 2 IN 1 injection resin to the corbel detail. Each area would be injected and monitored for a period of 3 weeks prior to the installation of the Delta Type C cavity drain system. To achieve a full belts and bridges approach, further tweaks to the design would be incorporated as and when different degrees of water ingress was encountered or where concrete to the scant piles were particularly poor, this included increasing levels of the G4 salt accelerant to the G4 Gel to increase speed of reaction without compromising the ability to spread to create the “waterproof curtain” behind the piles in the area.

As the entire sub-structure was susceptible to hydrostatic pressure, the best approach to the 5-levels would be to work one level at a time, working downwards in sequence.

Phase 2

The principles of the Type C, cavity drain system were straightforward and typical of a multi-level basement. Additional design considerations were incorporated for detailing the corbel on which mid floor slabs required a careful approach. Kevin suggested increasing the number of downward drainage weepholes from upper to lower levels for continued access for maintenance, along with discharge points.

In addition to this approach, compartmentalisation of the cavity drainage system was required for fire safety.

Case Study Results

When it comes to remedial waterproofing, a great waterproofing outcome is with waterproofing experts. This project has been one of partnering, from our partners at Koster UK to the main contractor, sub-contractor, and Delta Registered Installers Prestec Ltd who expertly installed the remedial solution.

Partnering in this project has been one of open communication, commitment of shared goals and mutual trust.

The timeframe for these remedial works were over a – year period, with works to levels 2 and 3 having already been completed. The overall strategy, continuous trials, site monitoring and the ability to adapt the overall waterproofing design throughout the project have enabled completion of the works to date to an incredibly high standard with all parties confident with the positive and collaborative approach.

Technical Waterproofing Consultants can assist with the right products for the right results, whilst using the correct methodology.

As a structure’s first line of defence to water ingress, a waterproofing design should offer long-term value, maximum performance, and a pragmatic design approach.

As with most, if not all structural waterproofing projects, selecting an appropriate waterproofing system is crucial in project success. Waterproofing design spans many disciplines, when designing an appropriate waterproofing system, a waterproofing design specialist will always take into consideration the end use of a space to ensure they have designed a suitable solution that will meet both standards and user requirements along with functionality.

A Waterproofing Designer’s philosophy defines what they wish to accomplish in the design of their waterproofing system and which principles they will use to do so. Identifying a robust and suitable design philosophy is an important aspect when designing a continuous system, as this will not only directly impact in how users install the system but also in future maintenance which will directly impact on the property owner.

Focus should be on a life-cycle oriented design, addressing life-cycle concepts and methods, deterioration and damage evaluation, life-cycle performance indicators, inspection and maintenance procedures all implemented to work in harmony.

There are many common pitfalls when it comes to designing a waterproofing system for podium decks, buried roofs, balconies, and terraces. Products do not fail! When failures occur, it is due to the design and build philosophy not being correct. The devil is in the detail – all waterproofing elements must be considered at the construction design stage to be durable and effective.

Delta Roof Guard waterproofing systems are certified Broof (t4), complying with the regulations on resistance and safety on flat roofs, mitigating fire risk.

Delta Roof Guard CP and QC practically bonds directly to substrates, providing a seamless, UV-stable membrane that does not delaminate.

Fire-retardant materials have a critical role to play in keeping modern buildings safe. However intense the fire, fire-retardant materials offer occupants of a building, valuable time for means of escape.

What is a Fire Retardant?

A fire retardant is a substance that is used to slow down or stop the spread of fire or reduce its intensity. This is commonly accomplished by chemical reactions that reduce the flammability of fuels or delay their combustion.

What is the Difference Between Fire Retardant and Flame Retardant?

Fire retardant and flame retardant both work to prevent fires, in occurrence of fires, it assists to stop the spread and help to reduce the amount of damage caused by flames. Both are invaluable to protecting homes and structures and provide extra time to for residents to safely evacuate a building in the event of a fire.

Fire retardant testing

Fire retardant materials, are measured on the degree to which a product contributes to the spread and growth of a fire, ways to measure this include:

How easily the product ignites
The amount of heat released when it burns
How fire spreads on its surface
The way in which it disintegrates as it burns
The quantity and nature of smoke released

These parameters contribute to the performance ratings, within the Euroclass system. Most building materials sold on the European market must be assigned a file indicating its fire resistance based on a Euroclass rating system. There are 7 Euroclasses of reaction to fire performance for construction products which extend from A1 to F

Delta Membrane Systems Limited believes it is a fundamental design approach that all occupied structures regardless of height or where there may be challenges in exiting the premises (regardless of height), should be constructed from materials which are fire-retardant.

April 2021, saw the introduction of the Delta MS 500 Fire Retardant System. This innovative Type C Waterproofing Membrane not only complies with BS 8102:2009 “Code of Practice for the Protection of Structures Below Ground” but also achieves a Euroclass rating of B-S2, d0 in accordance with EN 13501-1:2018.

In addition to fire tests carried out on the Delta MS 500 Fire Retardant System, Delta sought approval from the BRE (Building Research Establishment) for a further certification approval providing 3^rd party independent certification.

Paying attention to waterproofing products which offer protection in event of fire is not the norm. We hardly think of water management and fire in the same thought, however the benefits of doing so are not quite as crazy as it sounds.

The demand for sustainable, cost efficient building methods and materials is constantly increasing, as is the demand for safer building materials. The waterproofing sector should embrace and support the goal of creating healthy and safe living environments throughout the lifecycle of products.

There are many different design challenges experienced when designing a suitable, maintainable and capable waterproofing system. From existing basements to multi-level basements – basements which will encompass high water tables at some stage during their service life.

With Delta MS 500 Fire Retardant membrane it is now possible to specify a Type C, Cavity Drainage Membrane that offers not only protection from water or vapour ingress but also protection in the event of fire.

A Type C Cavity Drainage System is a maintainable basement waterproofing solution suitable for new-build basements, refurbishment and retrofit projects. The Type C System comprises of a Cavity Drain Membrane, Drainage system, Submersible Package Pump and Control System. This type of system is designed to combat water ingress and can be used to habitable grades 1-3 in according to BS 8102:2009.

The Delta Fire Retardant Type C Cavity Drainage System is the safest form of waterproofing system available, offering complete protection from water or water vapour and fire retardant protection.
