Covering London’s Commercial, Public and Residential Buildings
London’s complex urban landscape includes everything from heritage landmarks and social housing to retail centres, hospitals and industrial estates, each presenting unique flat roofing challenges. From thermal movement and UV degradation to cut edge corrosion and persistent ponding water, Allbase provides advanced liquid-applied systems engineered for durability and minimal disruption. Whether you’re overseeing maintenance in Islington or refurbishing commercial units in Croydon, our systems are supported by over 30 years of technical experience and designed to perform in busy metropolitan environments.
Commercial & Industrial
From units in Park Royal and Croydon to light industrial spaces in Barking and Brentford, commercial properties in London face weathering, cracked membranes and operational downtime. Our systems provide seamless, rapid-install waterproofing ideal for live trading environments.
Emergency Services
NHS sites like Guys & St Thomas’ Hospital, Royal London and numerous police and fire stations demand dependable flat roofing solutions. Our cold-applied systems install safely in sensitive, operational environments with no hot works or strong odours.
Education
From King’s College London and UCL to academies and primary schools in boroughs like Camden and Hackney, educational buildings across the capital face challenges such as RAAC, asbestos felts, thermal stress and cracked membranes. Our liquid-applied systems are cold-applied, fast-curing and ideal for phased installation during school holidays or limited-access timeframes.
Residential
Flats, terraces and housing stock across boroughs like Southwark, Lambeth and Ealing often suffer from ageing materials, leaks and heat stress. Our waterproof membranes restore and protect flat roofs on homes, garages and extensions without full strip-outs.
Heritage & Conservation
Listed buildings, museums and civic sites such as Somerset House and the V&A require non-invasive roofing systems that preserve architectural detail. Our liquid coatings are designed to protect historic structures without damaging original features.
Authorities & Housing Associations
Properties managed by borough councils and housing associations, including estates in Tower Hamlets, Waltham Forest and Westminster, benefit from our cost-effective waterproofing systems, backed by long-term guarantees and minimal disruption.
