What does BS 8579 tell us about the fire performance requirements of balconies and terraces?

Redclyffe-Road_JONL0196The 31st August 2020 was an important day for the external envelope industry.  It was the day that BS 8579:2020 Balconies and Terraces was published.  Why is this document so important you may ask?  Put simply, even though it is only guidance it is being looked at as THE document that unlocks the confusion over exactly what a balcony is, providing a clarification of exactly what type of balcony is a ‘specified attachment’ within Approved Document B Regulation 7.

 

If you haven’t had a chance to read this important new British Standard yet the answers are;Chelsea-Creek-1

  • Projecting open balconies, projecting enclosed balconies, recessed open balconies and recessed enclosed balconies are all balconies; whether thermally broken or cantilever.
  • Recessed open terraces, recessed enclosed terraces and access terraces are all roofs.
  • Terraces are roofs, but have a slightly different requirement depending on their distance from the boundary. But require a Broof(t4) fire exit route.

 

Not any clearer?  The simple way to remember the requirements are “if it’s over air it’s a balcony”, “if it’s over heated space it’s a roof”.

KTH96R Urban regeneration of industrial wasteland at King's Cross, Borough of Camden, London, England, U.K.

So, if it’s classed as a roof on a relevant building to demonstrate compliance with the requirements of Approved Document B the installed roof system must be either tested to BS EN 13501-5 and classified as either Broof(t4), Croof(t3), Droof(t4), Eroof(t4) or Froof(t4) depending on the distance from the boundary, or have a surface finish as defined by Commission Decision 2000/553/ EC of 6 September 2000; loose laid gravel with a thickness of at least 50 mm or a mass ≥ 80 kg/m2 (minimum aggregate size 4 mm, maximum 32 mm),sand/cement screed to a thickness of at least 30 mm, or cast stone or mineral slabs of at least 40 mm thickness.  However, in reality, most specifications are defaulting to a requirement of Broo(t4). But this still means you can use a BS EN 13501-1 Class E insulation board within the build-up, unless insurers require otherwise.

If it’s classed as a balcony (built over air) the entire build-up, apart from the waterproofing membrane, must be constructed of materials achieving fire performance class A1 or A2-s1,d0 to BS EN 13501-1, something called ‘non-combustible’.  This includes the insulation board and surface finished, but the roof membrane which is exempt under Regulation 7(3)(g).

Basement Waterproofing: How to Install a Basement Drainage System

Type C waterproofing system (cavity drainage)

Basement drainage and protection

Gas protection and waterproofing

If using a Type C waterproofing system (cavity drainage) to waterproof a basement, cellar or any below ground structure, a basement drainage system will be required to manage the evacuation of any water ingress which breaches the integrity of the structure.

Cavity Drainage ProductsThe principle of a Type C waterproofing system is to manage and control water ingress.  A basement drainage system will work with the Type C waterproofing system to keep the environment dry.

For the majority of projects, the two systems need to work together – a Type C system without suitable drainage will not keep a basement, cellar or below ground structure dry and a basement drainage system without a Type C system will not adequately keep a basement, cellar or below ground structure dry.

A basement drainage system is made up of four key components, a sump pump, drainage channel, a high-water level alarm and battery back-up.  On occasion the requirement for sump pump, high-water level alarm and battery back-up will not be required if there is a natural drainage to the structure, but this will be specified by the Waterproofing Design Consultant to that specific project.  With structural waterproofing solutions not one system fits all.

Basement Drainage Channels

Basement 2Drainage channels are water collection conduits designed to control water ingress.  These channels are installed around the perimeter of a basement, cellar or below ground structure. They feature a number of holes (preformed holes) that allow any water from the Type C cavity drainage system to enter the channel, then drain into a sump pump (submersible pump station) or suitable discharge point.

Once collected in the sump chamber, the groundwater can then be pumped to a safe evacuation point, often referred to as a ‘sump pump system’.

Drainage channels are available with or without upstands, and are supplied in durable straight lengths, the use of T-junctions, corner pieces, straight connectors, jetting eyes, end caps and access ports.

When designing basement drainage and channels, consideration should always be given to future maintenance. As with all drainage systems, it must be maintainable!

Basement Protection

A high-water level alarm and battery back-up are beneficial to the end user (homeowner).

A high-water level alarm will alert the homeowner when there is a potential fault with the sump pump system or if the sump pumps require a service.

A battery back-up will keep pumps running in the event of mains power failure.

val des portas 6 - Basement waterproofingInstalling basement drainage channels

Drainage channels are embedded into a preformed recess/gully at the floor wall junction of the structural slab.

When correctly installed, groundwater drainage channels will work with the Type C cavity drainage system to mitigate any hydrostatic water bearing against the structure (basement/cellar).

We recommend one sump pump system should be installed for each 50 linear meters of channel; the length of each channel running to the sump should not exceed 25m.

For anyone in a non-technical sense to fully appreciate the nature and risks associated with water ingress in below ground structures, we invite you to read this paper to gain an understanding of substructure waterproofing and the importance of remedial action. Potential consequences of active leaks are numerous, from cost for remedial works to reduction in building life cycle.

Sources of external water such as a high or rising water table, river, extreme weather, tidal changes, poorly drained soil, defective drains can all result in water penetration of a structure at below ground level.

North London luxury residenceThis penetrating water may have enough pressure and strength to ingress a structure, even one which is presumed to have been adequately waterproofed.

Basements and other below ground structures can leak both during and after construction. Any construction below ground will always be subject to groundwater.   Groundwater will try and will seep through cracks and joints in all construction. Joints (from movement to floor/wall junctions) will always require attention when waterproofing and these are common pitfalls in project fails.

Koster_2_IN_1-1There are often miscommunications and understanding of definitions of waterproofing. It is often presumed one waterproof system is enough to ‘waterproof’ a below ground structure, leading to a misconception that the structure is impervious to ground water.

Waterproofing design should always be undertaken by a Waterproofing Design Specialist, someone with a CSSW or equivalent qualification and to be designed to meet British Standard BS 8102:2009. A Waterproofing Design Specialist will always design a waterproofing system to reduce risk, this system will combine the project requirements with best practice. The successful choice, design and construction of a waterproofing scheme rely on heavily on communication between the manufacturer, design team, installer, contractor and owner – a better understanding of advice and practicalities encourage Best Practice and ultimately openness, transparency and accountability.

Stopping Active Water LeaksRemedial work to active leaks in construction, which is exposed, are relatively easy to find and fix. If the construction is not exposed and finishing’s are in place, these leaks are difficult to find but not impossible. Use of a thermal imaging cameras/borescopes/moisture meters or visual inspections are usually enough to locate these leaks.

Depending on the leak itself will depend on the remedial work required. It is important to understand the waterproofing options available and how these will have a cost and time implication to a project.

Five Tonnes of Plastic Saved from Landfill in 2019 by Award-Winning Recycling Service

Building Products Index Ltd waterproofing Leave a Comment

View the Newton Waterproofing entry on BPindex

Visit the Newton Waterproofing website

An innovative and unique recycling service set up by Newton Waterproofing has saved 5.174 tonnes of plastic from going to landfill in 2019.

The UK’s leading independent designers and suppliers of guaranteed waterproofing and damp proofing systems had 223 bags of HDPE membrane returned to them throughout the course of the year as part of the Newton Membrane Recycling Scheme.

Recycling-membrane-scene-rgbBy recycling waste plastic into new products instead of manufacturing from new HDPE, during 2019 alone Newton have prevented 5.944 tonnes of CO2e emissions from being released into the atmosphere; the equivalent of burning 1.96 metric tonnes of petrol and saving enough energy to make 826,200 mugs of tea.

Furthermore, since the scheme’s launch in 2017 it has successfully prevented over 13.7 tonnes of plastic from going to landfill, equivalent to preventing 15.746 tonnes of CO2 from entering the atmosphere.

It’s no surprise, then, that the service has won six awards in just over two years, including the ‘Charles Darwin Award’ from the British and Irish Trading Alliance (BITA); the ‘Commitment to the Environment Award’ at the Kent Excellence in Business Awards (KEiBA); the prestigious ‘Innovation of the Year’ award from the National Building Awards; and the ‘Sustainability’ award at the Property Care Association Best Practice Awards.

Newton Waterproofing’s Managing Director Warren Muschialli said: “Our innovative recycling service had another tremendous year in 2019 and, as well as the environmental benefits, we also saved 223m3 of skip space on site, equivalent to more than 24 full skips and therefore 50 skip journeys. This obviously delivers further emission and cost savings.”

The closed-loop scheme works in collaboration with the company’s Newton Specialist Basement Contractors (NSBC) who collect waste off-cuts of plastic membrane on their projects.

The waste is then collected by Newton at the same time as making deliveries of new materials, therefore preventing additional emissions from transporting the plastic. Finally, the material is chipped into small granules by Newton, then collected by a national recycler for reprocessing and reusing to make new products for the construction industry.

“We are proud to operate what is the only recycling service in the waterproofing industry,” added Warren.

“With the Government setting a target of net-zero carbon emissions by 2050, it presents the construction industry with a wonderful opportunity to make a difference.”

Newton Waterproofing design and supply guaranteed waterproofing and damp proofing systems for all structures, from large-scale commercial developments to new build and existing domestic properties. For more information, call 01732 360 095 or email info@newtonwaterproofing.co.uk.   

Fire Regulation Compliance for Roofs

Building Products Index Ltd Roofing, waterproofing Leave a Comment

View the Radmat entry on BPindex

Visit the Radmat website

RockFace installationFollowing the Grenfell Tragedy in June 2017, and the subsequent investigations, the Governments of England and Scotland made significant changes to their respective Regulations related to fire performance.   Approved Document B Volumes 1 and 2 in England, and Technical Handbook Annex 2.C and 2.F in Scotland, introduced a new category of ‘relevant buildings’ with the aim of reducing the fire risk in high rise buildings (those over 18m in England and over 11m in Scotland).

RockFace A2 high resWhilst generally clear with regards to the fire performance requirements for external wall construction (external wall systems on buildings over 18m high have to be fire resistant, achieving class than A2-s1, d0 or Class A1 under the European classification system set out in the standard BS EN 13501-1, subject to exemptions) the regulation changes have resulted in some confusion with regards to the fire performance requirements for roofing systems, and the definitions of ‘specified attachments’, insulated balconies, roof terraces and podiums.

With the entire UK Government in Purdah (the period leading up to an election, during which government departments generally refrain from making any new announcements) the Ministry of Housing, Communities and Local Government (MHCLG) are unable to make further clarifications, however what is clear is that:

  1. Roofing systems must achieve Broof(t4) European classification in accordance with BS EN 13501-5.
  2. Roof finishes covered under the Annex of Commission Decision 2000/553/EC are considered to be unrestricted under the national Requirements (Loose laid gravel with a thickness of at least 50 mm or a mass ≥ 80 kg/m2, Sand/cement screed to a thickness of at least 30 mm or Cast stone or mineral slabs of at least 40 mm thickness).
  3. Any decoration or other finish applied to any external (but not internal) surface forming part of the wall must achieve class a minimum A2-s1, d0 classification to BS EN 13501-1.

This latter requirement means that any insulation board used as part of the roofing system where it abuts an external wall must be non-combustible, effectively banning the use of PIR, XPS and EPS insulation boards between the vertical waterproofing and the external wall.

In warm roof applications it is easy to switch the vertical upstand board in this application to mineral wool or cellular glass, but with no suitable product available for inverted roof applications specialist roofing system manufacturer Radmat Building Products had to develop a suitable solution quickly.

RockFace A2 Product high resProTherm RockFace A2, a non-combustible upstand insulation board for inverted roof applications, consists of a special mineral wool insulation board factory laminated to a 6mm Cement Particle board.  This combination, tested by WarringtonFire to BSEN1350–1, achieved an A2-s1, d0 rating.  Radmat Building Products believe that this is currently the only inverted roof upstand insulation board available that meets the requirements for ‘Relevant Buildings’ within Approved Document B, and the Scottish Technical Handbooks (those over 18 m in England and over 11m in Scotland).

Newton Waterproofing has exclusively partnered with RASCOR International to bring the Switzerland-based company’s unique RASCOtank system to the UK.

R-Logo_Pantone 526C_mit Claim_EN

Often referred to as the ‘White Tank’ engineered waterproofing system, the RASCOtank system ensures that the concrete acts as both the structure and the waterproofing.

The Newton RASCOtank System will provide a unique form of Type B structural waterproofing for any new concrete construction project occurring below-ground in the UK.

Newton and RASCOR’s design team will work with the client, the structural engineer, the architect and the contractor from the outset of a project to achieve the required waterproofing strategy.

With this approach the Newton RASCOtank system provides the principal contractor and the client with savings on the financial and programming of the project and, as the system allows for unlimited pour sizes for the concrete floors and walls, maximum efficiency is also achieved.

RASCOR (3) copyA unique method allows Newton to control the locations of the inevitable cracks that occur in the concrete by use of the patented RASCOtec crack inducers. Deliberately placed at intervals within your concrete pour, the inducers allow for significantly bigger pour sizes, remove the need for the traditional chequer board method, and allow for unlimited concreting and any depth of floor or wall.

Ruben Schmid, Executive Director at RASCOR International said,“Newton are the perfect match to RASCOR. Each company has vast knowledge and experience, and is an expert in their respective areas of waterproofing. This new partnership means that Newton and RASCOR will be able to offer the best waterproofing solution in any combination on any project for our UK clients, and will put us into a leading position in the UK market.”

The exclusive partnership with RASCOR, an international group with over 50 years of experience in the design, manufacture, installation and warranty of Type B waterproofing for concrete structures all over the world, marks the beginning of a powerful new chapter in concrete waterproofing for the family-run business, based in Tonbridge, Kent.

 “RASCOR are pioneers in Type B waterproofing and we are absolutely delighted to be their exclusive partner providing the Newton RASCOtank system in the UK,”commented Newton Waterproofing’s MD Warren Muschialli.

“As the UK’s oldest independent designers and suppliers of guaranteed waterproofing systems for all structures, with 170 years of industry experience and expertise, we are their perfect partner.”
