Waterproofing and damp-proofing new & existing basement structures


Maintaining low moisture levels and removing any stagnant water from concrete structures will lengthen their longevity. Concrete Remedial Systems are committed to providing waterproof solutions, covering different options for protecting external and internal concrete structures from water ingress. For above and below ground structures, our certified staff offer a thorough scope of waterproofing including barrier protection, cementitious coatings, tanking membranes and cavity draining solutions.

Our Concrete Waterproofing Solutions

Whether new build or refurbishments, Concrete Remedial Systems apply waterproofing systems in line with BS 8102:2022 (the British standard for protection of structures against water from the ground). Our work and services all provide a warranty for a minimum of 10 years.

Type A - Barrier Protection

Through introducing cementitious protective coatings, we can enhance the level of waterproofing. These liquid membranes shield porous concrete from surface water and moisture, preventing water retention. Applied in layers on concrete floors, walls and ceilings, we use a variety of products to ensure a strong standard of waterproofing.

Type B - Integrated Waterproofing System

Completed during construction, this method of waterproofing utilises the structure itself to create a barrier. All new builds compliant with BS 8102:2022 will have factored in external walls for basement builds that keep out water.

Older domestic and commercial builds constructed before integral barriers were essential for concrete structures may not have external barriers built in line with regulations. In this case, Concrete Remedial Systems are on hand to apply waterproofing directly to the surfaces using Type A and Type C.

Type C - Cavity Drainage

Cavity drain membrane (CDM) systems are a maintainable, internal basement waterproofing solution referred to as ‘Type C’ waterproofing in British Standard 8102:2022 and are ideal for new-build, refurbishment and historic/listed projects. Known as the most failsafe form of waterproofing, the cavity drain membranes capture ingressing water at the point of ingress and directs it to an integral pumping system or drainage outlet for safe removal.

Protective Coatings

Protective coatings greatly extend the life of concrete structures. This can greatly extend the life of concrete structures by enhancing the durability of the concrete with a protective coating. This could be the difference between your structure lasting 30 years or having to be completely replaced at great expense after 5, or less years.
