Concrete waterproofing provides protection against water damage which can lead to costly repairs down the line. Concrete structures, including basements, garages and warehouses, are all susceptible to water damage both internally and externally. Different waterproofing measures can help defend concrete against moisture and damp. At Concrete Remedial Systems, we provide a range of different waterproofing solutions to keep your property as water-tight as possible.

Our team of concrete experts work alongside property owners, builders, engineers, architects and contractors. We consult during building work, ensuring that all regulations for waterproofing are met. Our team can tackle large scale jobs for larger buildings, working on concrete restorations and repairs as well as waterproofing. Our service also includes protective coatings to shield repaired concrete from future water-related issues. If you are based in West Sussex, we can arrange a site visit to carry out an inspection to determine where and how we can help.

Concrete Waterproofing and Tanking in West Sussex

Concrete Remedial Systems work to waterproof underground concrete structures 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. Our waterproofing systems protect existing structures from water retention and damp. We use a combination of systems to ensure structural integrity.

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

As this waterproofing system is factored in during the construction of the basement, type B isn’t something that we can provide. 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 for Concrete Buildings in West Sussex

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.

What is waterproofing and why is it important?

Waterproofing concrete involves applying water-resistant barriers on the surface of the concrete, either using liquid or solid membranes. Construction also brings into consideration creating a water-tight space, using sealed joints to keep free water out. For basements, cavity drainage removes free water from where it gathers underground, keeping concrete structures clear of water.

Water causes the most long-term damage for concrete because the material is semi-porous. Water penetrates the surface, entering the structure. During extreme weather and temperature changes, the freeze-thaw cycle causes cracks to form which creates a greater surface area for water to enter. Crack become larger, threatening the structural integrity of the concrete. As a result, the concrete starts to flake away, leading to spalding and even collapse.

How do I know if my basement needs waterproofing?

Look out for signs such as dampness, mould growth, or water seepage. If you notice cracks, the chances are water has entered the concrete and caused damage. If this is the case, we can still help and repair the damage. We’ll seal any cracks and waterproof your basement to keep it dry and damp-free. Our experts can assess your property with a thorough survey to check for any unseen damage.
