System Type: Liquid Waterproofing

Central Criminal Courts

A comprehensive roof refurbishment project was successfully delivered at the Central Criminal Court in London, encompassing approximately 1,700 sqm of critical roof area within one of the UK’s most high-profile and operationally sensitive judicial buildings.

The existing asphalt roofing system, which had reached the end of its serviceable life, was fully removed and replaced with a high-performance tapered warm roof solution. This modern system was specifically designed to significantly enhance drainage efficiency, eliminating standing water risks, while also delivering substantial improvements in thermal performance.

To provide long-term assurance and added value, the works were completed with a comprehensive 20-year warranty.

Given the building’s importance and continuous use, the project was carefully planned and executed to minimise disruption, ensuring seamless coordination with on-site operations and strict adherence to health, safety, and security protocols.

Milne Avenue, Cambridge

This large-scale build-to-rent residential development in Cambridge delivered 373 high-quality new homes and required an extensive roofing and waterproofing package spanning approximately 5,500 sqm.

Skyler delivered a fully integrated solution incorporating waterproofing, insulation, and a variety of roof finishes across the development.

A hot melt waterproofing system was utilised extensively, providing a robust and long-lasting solution ideally suited to large, complex roof areas. This was combined with XPS insulation to enhance thermal efficiency and a ballast finish to ensure durability and protection against environmental exposure.

In addition, selected areas were designed to deliver sustainability benefits through the installation of green roof systems. These incorporated paving walkways to facilitate safe access and maintenance, alongside man safe fall protection systems to ensure full compliance with health and safety requirements.

Monier Road, Hackney Wick

This residential development in Hackney Wick comprises 150 apartments and townhouses across two blocks, requiring a technically diverse and high-performance roofing solution.

Skyler delivered a multi-system package including standing seam metal roofing with Rockwool insulation, bituminous hot melt with foam glass insulation, and liquid waterproofing to address complex detailing.

Roof finishes incorporated green and blue roof systems to support sustainable drainage and biodiversity, alongside paved areas with ballast and bespoke perimeter cappings.

The package was further complemented by modern metal decking on balconies and terraces.

Fully integrated mansafe systems and abseil points ensured safe long-term maintenance.

The result is a durable, compliant, and future-proof roofing solution aligned with modern residential performance and sustainability standards.

Polymex House, Peckham

This new-build development, constructed on the former site of the historic R. White’s Lemonade and Edison Bell factory, delivered a mixed-use scheme comprising 170 residential units and ground-floor retail space. The project included approximately 3,300 sqm of waterproofing works and associated roof finishes.

Skyler delivered a comprehensive roofing and waterproofing package, with bituminous hot melt systems and XPS insulation utilised extensively across the development. This combination provided a durable, high-performance solution offering excellent thermal efficiency and long-term waterproofing integrity.

Blue roof zones were integrated with green roof systems across the development to combine enhanced drainage control and ecological benefits.

Paved finishes were installed across selected roof areas, balconies, and terraces, creating functional and aesthetically consistent external spaces while ensuring protection of the underlying systems.

 

 

Lombard Square, Plumstead

This major regeneration scheme delivers 1,913 new homes over approximately 47,000 sqm of residential, community and commercial spaces.

Delivered across three phases, Skyler has undertaken site-wide waterproofing works totalling approximately 22,000 sqm, supporting the phased evolution of the development and ensuring continuity of performance across multiple build stages.

Given the scale and complexity of the scheme, a multi-system approach was adopted to meet varying design, performance, and programme requirements. This included the installation of bituminous hot melt systems, built-up felt roofing, and cold applied waterproofing solutions, all integrated with non-combustible insulation to meet stringent fire safety and regulatory standards.

Roof finishes across the development incorporate a combination of blue and green roof systems, alongside paved and decked areas, delivering a balanced approach to sustainability, water management, and user access.

The result is a robust, high-performance waterproofing strategy that delivers a professional, future-proofed solution for this large-scale regeneration project.

Rennie Estate, Bermondsey

This 12-storey residential development required a carefully engineered, multi-system waterproofing solution designed to deliver long-term performance across a range of roof and balcony areas.

Skyler installed a built-up felt roofing system providing a robust solution well suited to high-exposure zones where durability, reliability, and long-term weather resistance were critical.

The two principal roof areas were finished with a combination of green roof and ballast. These solutions contribute to sustainable drainage performance and improved thermal regulation, whilst also supporting biodiversity.

Private balconies were completed using a cold-applied liquid waterproofing system, offering a seamless and highly adaptable solution ideal for tight access conditions and intricate interfaces.

A fully integrated man safe system was also installed across key roof zones, ensuring safe and compliant access for ongoing maintenance.

Dockley Road, Bermondsey

This scheme in the heart of Bermondsey offered accommodation and retail units.

The roofing and waterproofing comprised of over 4,000sqm of hot melt including complex paving finishes. This was the main part of the project for Skyler.

Separate systems used on the project for various areas throughout the scheme were: the 500sqm of three layer felt system with PIR Insulation and green roof.

London South Bank University

The university required a full roofing upgrade to replace an outdated system that no longer met performance or thermal efficiency standards. Skyler was appointed to deliver a comprehensive solution designed to enhance durability, energy efficiency, and long-term asset value.

Our team successfully removed over 4,500 sqm of the existing roof. The new installation incorporated a high-performance Hot Melt Waterproofing system combined with XPS insulation.

To further optimise water management and sustainability, a bespoke Blue Roof attenuation system was integrated, effectively controlling rainwater runoff and supporting drainage efficiency.

In addition, approximately 900 sqm of Three-Layer Felt roofing with PIR insulation was installed, ensuring consistent performance across varied roof areas.

The project was completed with high-quality ballast and paving finishes.

West Hampstead Square

Skyler were principal contractor for these six residential blocks in West London.

The requirement was to renewal the waterproofing system to all roof areas and reinstate the existing finishes.

Logistics were extremely challenging as the development sat between two of London’s main train lines. Careful planning and execution of the works were completed without any incidents.

St Pancras Way

The project at 104/106 St Pancras Way proved challenging for a number of reasons. Firstly, the roof had leaked for a number of years as numerous detailing elements to the roof had broken down with time.

Skyler identified the causes for water ingress and promptly commenced.

Skyler’s proposal for a seamless waterproofing system was key in providing a complete solution for these historical problems.

The central gutter areas were completely re-lined and fully waterproofed along with a number of complex penetrations and closer details. These were addressed, including the full waterproofing to the entire field area of the roof.

Diligently working throughout, Skyler maintained water tightness for the building throughout the programme.
