Converting a public house into two luxurious dwellings

Overview

Delta Registered Installers, Prism Construction successfully restored a dilapidated former public house into two modern properties, despite initial concerns from the structural engineer about potential collapse of two sections.

This scope of this project was converting an abandoned and damp structure into two modern, dry dwellings, ensuring a complete transformation from neglect to contemporary living spaces.

The trend of converting pubs into residential properties presents substantial opportunities. These structures hold immense potential for transformation into highly desirable residential spaces.

The building’s original solid brick construction was in excellent condition, highlighting the era’s high-quality craftsmanship.  This building presents a complex layout with varying ground levels along its frontage and side elevations, adjacent to the road.

Plans include raising the first floor for more headroom, replacing timber floors affected by wet rot, and addressing the solid concrete plank floor in unit two, which is slightly below ground level to the front elevation

Ensuring comprehensive waterproofing or damp proofing for any subterranean structure is essential to maintain and protect a building’s structural integrity.

When specifying a retrofitted waterproofing solution, considerations should include site contamination, head heights, and retaining walls.

Methodology

A thorough structural survey is essential for any pub-to-residential conversion. Experts assess building integrity, evaluate load-bearing walls, and identify structural challenges that may impact the process.  Working in collaboration with the Structural Engineer and Developers, Delta’s Technical Team provided expert advice and guidance throughout the project. Delta tailored a waterproofing design to meet specific project requirements.

BS 8102:2022 categorises waterproofing into four performance grades: 1a, 1b, 2, and 3. These grades specify the required waterproofing standards to match client expectations.  For example, while commercial or industrial environments may allow some dampness (Grades 1a and 1b), residential areas necessitate complete dryness (Grade 3).

The new timber floors must be isolated. Delta’s Technical Team suggests using Delta High Performance DPC.  The plank floor will experience lateral dampness from high ground levels. Once the structure is stabilised, the floor should ideally be replaced with an isolated timber floor. Waterproofing options were also discussed.

A ‘Type C’ Waterproofing System was selected as a maintainable waterproofing solution to the existing basement to ensure a Grade 3 habitable environment was achieved.

BS 8102:2022 outlines three primary waterproofing methods: Type A (Barrier), Type B (Structurally Integral), and Type C (Drained). For habitable spaces, a combination of two methods is preferred, known as combination protection. These systems should possess different performance characteristics to reduce the risk of a common failure cause.

Type A

Delta’s Technical Team recommended two coats of Koster NB1 be applied to the front face of the brickwork and LGF slab before the installation of the proposed “Type C” cavity drained protection system.

Preparation of the substrate prior to the application of Koster NB1 is essential. Typically, where Type A tanking is carried out internal 90 degree angles should be filleted with Koster Repair Mortar Plus. Any voids should be filled and loose masonry adequately pointed with Koster Repair Mortar Plus.

This in effect provided a “Type A” form of waterproofing in addition to the proposed internal “Type C”, with the principle of designing out risk.

It is essential to treat all new concrete, including the basement slab and walls, with a free lime treatment.  Koster Polysil TG 500 was spray applied to prevent free lime build-up.

Free lime and mineral salts leaching from concrete can cause Type C Drained Protection Systems to fail. According to BS 8102:2022 Section 10.2.1.2, these substances deposit within cavity drainage systems, perimeter channels, and especially sump chambers, leading to blockages and potential system failure.

Type C

Delta’s Type C, Cavity Drained Protection System (CDM) supports slight movement and vibration without affecting structural dynamics.  It permits moisture or water to travel behind the membrane in a controlled drainage system, requiring minimal substrate preparation.

Walls above external ground level can be affected by rising dampness. Therefore, using a cavity drain membrane (CDM) as a damp-proofing medium was essential. Delta’s Technical Team advises lining all walls with the Type C system.  With combination waterproofing (Type A and C) only required for retaining walls.

Delta MS 500 was installed on walls, with Delta MS20 laid on the floor and joined to the MS 500 wall membrane. Delta FM was deployed to the concrete plank at first floor level to protect against lateral capillary held moisture.

Delta drainage channel was inserted adjacent all retaining walls and taken to non return valves to evacuate via gravity due to the topography of the site.

The existing solid staircases were retained and prepared prior to the application of Koster NB1.

Where insulation is provided a vapour control layer is recommended on the warm side of the insulation.

All installed with great dealing and expertise.

Building Products Index Ltd waterproofing Leave a Comment

View the SOPREMA UK entry on BPindex

Visit the SOPREMA UK website

SOPREMA UK has expanded its CPD offering for architects and specifiers with the launch of a new RIBA accredited seminar focused on flat roof fire performance and regulatory compliance. Now available to book through the RIBA CPD Providers Network, Understanding BROOF(t4): Flat Roof Regulatory Requirements and Verified Product Information addresses one of the most critical and closely scrutinised aspects of roof design.

Developed for professionals involved in specifying and designing flat roof systems, the CPD focuses on external fire performance requirements, system testing and the importance of verified product information when demonstrating compliance, offering practical guidance to support informed specification decisions.

RIBA Accredited Learning via the CPD Providers Network

Through its CPD RIBA Approved Providers Network, RIBA works with carefully assessed industry experts to deliver high-quality, impartial learning content. Only CPDs that meet RIBA’s strict criteria for relevance, technical accuracy and educational value achieve accreditation, giving architects confidence that the time they invest genuinely supports their professional growth.

SOPREMA UK’s Understanding BROOF(t4) CPD has been developed with these expectations in mind, addressing the practical challenges architects face when interpreting fire performance requirements and specifying compliant flat roofing systems.

Understanding BROOF(t4): Why This CPD Matters

Fire safety is one of the most heavily scrutinised aspects of building design, yet BROOF(t4) is often misunderstood. Simply put, BROOF(t4) is the highest classification within the UK and European system for assessing external fire performance of roofs. It demonstrates that a roof system has been tested and proven to resist fire spread from external sources. However, as many architects know, the reality is more complex.

SOPREMA’s CPD breaks this topic down into clear, practical terms by:

  • Explaining how external fire performance is classified
  • Clarifying commonly misunderstood terminology
  • Outlining how tested roof system performance should be interpreted when designing or specifying flat roofs
  • Highlighting typical areas of confusion and risk, supporting designers in making informed, evidence based decisions
  • Using clear, factual language, aligned with current expectations for accurate and responsible construction product information

By looking at regulation in relation to real-world roof design, the course gives architects the confidence to specify systems correctly the first time.

In an increasingly regulated environment, trust in product information is essential. That’s why SOPREMA’s CPD also looks closely at the Code for Construction Product Information (CCPI). The CCPI plays a vital role in raising standards across the industry by ensuring product claims are clear, accurate, up to date and unambiguous.

For SOPREMA UK, CCPI is central to how we communicate performance, testing and system suitability.

Learning Backed by Technical Expertise

With over 100 years of global experience in waterproofing, insulation and roofing systems, SOPREMA combines manufacturing expertise with deep technical understanding.

Whether you are just starting out in your career or are an experienced specifier, SOPREMA’s Understanding BROOF(t4) CPD offers valuable insights into both regulations and practical application.

Design for the future

Complying to current and future legislation, making buildings future-proof and carbon-neutral is a key concern for architects and clients today. Innovative solutions that last the lifetime of the building and reduce the pressure on the planet are now taking centre stage. However, these are not always new technologies or products – while some solutions directly tackle specific challenges, others are more systemic, helping to create the conditions under which all other solutions can be adopted at a greater scale and pace. Implementing complementary innovations together can provide far more significant outcomes than implementing them in isolation.

Protecting the fabric of the building with reliable waterproofing has always been vital, but now, NHBC’s Technical Guidance 9.2/06 ‘Substrates for tiling bath and shower enclosures, wet rooms and bathroom pods’ reinforces this. In essence, any new home whose foundations begin on or after 1st January 2025 in the UK, must comply with this guidance if an NHBC warranty is to be provided.

In short, magnesium oxide boards must not be used, and in wet rooms or bathrooms with power shower, there are strict requirements; only tile backerboards that hold technical approvals acceptable by NHBC can be used.

Critically, whatever the subsurface, all tanking solutions must have appropriate 3rd party certificates such as a European Technical Assessment (ETA) and the tile, adhesive and grout should be compatible with the selected waterproofing system.

Does your new build project have a bathroom or a wet room? wedi has you covered.

100% waterproof and directly tileable XPS boards and shower formers manufactured by wedi hold all required certificates to comply with NHBC’s new guidance; from Environmental Product Declarations (EPD) and A+ VOC label, through the European Technical Approval (ETA), to CE, UKCA and UKNI markings. Furthermore they also comply with Building Regulations section M4(2) and M4(3).

Using renowned, waterproof XPS tilebacker boards to waterproof floor and wall surfaces in wet rooms and bathrooms, not only reduces installation steps and hence minimises the risk of failure, but together with clever accessories and interlocking XPS components such as floor-level shower elements, benches, niches and ready-to-use partition walls, also provides a floor-to-ceiling, systemised waterproofing solution. When installed correctly, they last the lifetime of the building in which they are installed.

Since September 2021, wedi has been part of the Ardex Group and therefore compatible grouts and adhesives can also be provided under one comprehensive, 10-year product warranty. One manufacturer, one responsibility – everything under the tiles, from a single source – so that architects can stay focused on the design.

Product characteristics such as 133kg/m2 vertical weight-load capability make the wedi building board a universal solution for all types of tiles, natural stone and slab coverings. Regardless of the selected tile format/size, in conjunction with reinforcement plates, they hold larger items such as floating washbasins, doors and radiators, meaning that multifunctional partition walls can also be created quickly and easily, ready-to-tile the next day.

Another advantage is the low U-value of 0.036 W/mK, that contributes to the thermal insulation of the room from the inside, therefore contributing to the energy efficiency of the home. This makes them perfect to use beneath under-tile-heating (UTH) systems of all kinds.

In 2025, compliance with the Future Homes Standard will become mandatory; all new homes built from this year are to be future-proofed with low carbon heating and world-leading levels of energy efficiency. Carbon emissions should be reduced to 75-80% less than previously accepted.

Whilst wedi XPS elements do not directly tackle such challenges, they create the conditions, under which other solutions can be adopted easier and faster. By cutting back on installation steps, such as tanking or priming for example, they reduce the required interfaces on site and hence accelerate the project progress. What’s more, used as a waterproof insulation beneath heating systems, they prevent heat-escape and hence improve heating systems’ response time by up to a staggering 70%!

At the forefront of innovation since 1983, wedi is doing everything possible to support energy-efficient, future-proof bathrooms. The current rise of heat pump operated water heating systems prompted the development of the wedi PreLine building board for example. The factory-cut precise grooves greatly reduce the risk of the pipe runs being accidentally damaged as well as ensure the even placement of pipes as close to the surface as possible. It is equally suited to floor or wall applications.

Furthermore, wedi also offers a multitude of floor-level shower elements in different formats -whether it be linear or point drainage, a standard, rectangular or a round, maybe a shell-shape with matching free-standing walls, the wedi Fundo range has the right product for your project. Why not check out the newest member of the range? The Fundo Flex provides an entirely new concept for shower design – it fully adapts to requirements, allowing for an exacting design without the drawbacks. Drain location as a prime concern in shower design? It is now a thing of the past.

Value Engineering – Waterproofing

Building Products Index Ltd Waterproof Membranes, waterproofing Leave a Comment

View the Delta Membranes entry on BPindex

Visit the Data Membranes website

Value engineering is a method to deliver essential project functions at the lowest cost. It substitutes materials and methods with cheaper alternatives without losing functionality. Focused on functions rather than physical attributes, value engineering is also known as value analysis.

Value engineering reviews products in the design phase to cut costs and boost functionality, enhancing product value. It aims to produce items cost-effectively without compromising their purpose. The concept of Value Engineering began at General Electric Co. during World War II.  During the war, there were shortages of skilled labour, raw materials, and component parts. Lawrence Miles and Harry Erlicher at G.E. sought suitable substitutes.

Aligning Value Engineering with Structural Waterproofing

Messrs Miles Erlicher defined product value as the ratio of function to cost. Function is the work an item is designed to perform, and cost covers its life cycle expenses. Increasing product value involves enhancing function or reducing cost. Value engineering includes analysing costs related to production, design, maintenance, and replacement.

Product value        =           Function

                                            _________

                                                  Cost

Waterproofing requires a tailored design approach, as there is no one-size-fits-all solution.  So, to achieve value engineering in structural waterproofing, consideration should be given to product, product performance characteristics, installation, future maintenance and worst-case scenario, refitting flawed or failed systems.

Waterproofing is vital for maintaining the integrity and value of a structure. Poor workmanship, wrong materials, lack of preparation, or missed details during installation can cause failed waterproofing systems, leading to water damage and expensive repairs.  Addressing waterproofing issues early ensures a structure stays in great condition. Although waterproofing costs only 2-5% of a building’s total expense, to rectify failed or flawed waterproofing, can account to nearly 80% of all construction-related problems.

Effective structural waterproofing relies on precise product selection and proper installation methods from the start.

Waterproofing Design

Waterproofing design is essential in construction, employing various methods and materials to prevent water ingress. Effective waterproofing design enhances building longevity and safeguards structures against water damage.

Three key stages to successful waterproofing: design, specification, and installation.

The waterproofing designer will assess “value” and incorporate this into their design.  Not all waterproofing products/materials are equal.  Different products offer varied qualities and features, so it’s important to choose the right one for the project.

A Waterproofing Design Specialist must know various waterproofing systems and BS 8102:2022. They should understand water sources, their interaction with structures, and soil flow. Structural principles and geotechnical knowledge are essential for working with engineers and interpreting soil reports.

Visit the Soprema website

A Modern Approach to Construction

Student accommodation has evolved significantly over the past decade, with a strong emphasis on durable materials, sustainability, and occupant well-being. The Spireworks, a contemporary student accommodation development located at 163 Cowley Road in Oxford, reflects this evolution, showcasing effective construction techniques and reliable materials.

Completed by main contractor RG Group for student accommodation provider Aparto, The Spireworks is a £21 million development that integrates seamlessly into Oxford’s vibrant and eclectic surroundings.

Designed by ICA Architects, the scheme delivers 137 student bedrooms alongside a range of communal spaces, including a gym, games room, study areas, and an outdoor courtyard. Retail and service facilities within the development also enhance the local community’s amenities.

Reliable Building Envelope Solutions

A crucial element of The Spireworks project was the roofing and waterproofing system, which needed to deliver durability, energy efficiency, and long-term performance. Specialist contractor Roofworx (UK) Ltd was appointed to manage this complex installation, ensuring the specified solutions met the required standards.

Matthew Coupe, Managing Director at Roofworx (UK) Ltd, explained: “The roofing and cladding package was particularly challenging, with multiple interfaces and a phased construction programme. Early involvement in the design stages was key, enabling us to collaborate closely with ICA Architects and specify products that would ensure longevity and performance.”

SOPREMA’s solutions were specified for the roofing works, delivering a full building envelope system that offered both waterproofing integrity and thermal efficiency. The project incorporated a total of 1,200m² of SOPREMA’s products:

  • 720m² of DUOFLEX hot melt system with 200mm SOPRAXPS insulation and 56mm cement board upstands for the main roof.
  • 450m² of SOPRATORCH bituminous membrane multi-layer system, combined with SOPRATHERM PIR tapered insulation on various levels.
  • 50m² of FLAGON single ply membrane for all canopies and lift-over runs, incorporating edge trims and drips.

 Overcoming Challenges for a Seamless Installation

Every construction project presents unique challenges, and The Spireworks was no exception. With a phased build programme and an initial two-month delay due to external factors, meticulous planning was essential to keep the project on schedule.

“The project required strategic sequencing as the building was constructed in two halves,” said Matthew Coupe. “Additionally, persistent wet weather during winter months posed further delays. To counter this, we specified SOPRADVANCE concrete compound, a SOPREMA solution that enabled application to the concrete deck after just seven days instead of the standard 28-day curing period. This allowed us to accelerate the programme without compromising quality.”

Logistics also played a critical role, as the project’s central location within Oxford’s narrow streets meant material deliveries had to be precisely timed. Roofworx worked closely with SOPREMA to coordinate deliveries, ensuring smooth progress and avoiding disruption.

Quality assurance was another key consideration. SOPREMA’s in-house field technicians conducted thorough on-site inspections at every stage of the installation, ensuring all waterproofing elements met required performance standards. Furthermore, all operatives received full SOPREMA system training, ensuring a consistent standard of workmanship.

A Lasting Legacy for Oxford’s Student Community

Despite initial setbacks, The Spireworks project was successfully completed on time and within budget, delivering a modern, comfortable, and durable living space for Oxford’s student population. The collaboration between Roofworx, ICA Architects, RG Group, and SOPREMA played a pivotal role in overcoming challenges and ensuring the necessary standards were achieved.

The success of the project underscores the importance of early-stage collaboration, the right product specification, and technical expertise in delivering durable, future-proof buildings.

Today, The Spireworks provides students with a safe and well-constructed living environment for years to come.

Inevitably as sustainable requirements within the construction sector rise, waterproofing of wet areas is also facing stricter regulation. Rising issues and failures across bathroom, wet room and shower installations with water ingress and leaks, prompted NHBC to issue the technical guidance 9.2/06 in the area of substrates for tiling with special attention to tanking systems used beneath tiles.

wedi can offer not only 100% waterproof and loadbearing (133kg/m2) XPS tilebacker boards and shower elements with all required certifications (UKCA, CE, UKNI, EPD, BBA), but as part of the Ardex Group, also compatible adhesives and grouts for direct tiling without the need of additional waterproofing cutting back on risks associated with additional installation steps.
