Type A Waterproofing and Cementitious Waterproof Coatings

Barrier protection makes use of materials that shields concrete from water admittance. Applied directly to the surface of concrete floors and walls, barrier protection gives existing concrete structures an added layer of waterproofing that will greater lengthen the longevity of the concrete itself. Concrete Remedial Systems provides multiple types of waterproofing, helping to protect basements, commercial buildings, car parks, stadiums and all manner of properties from water damage.

Barrier Protection & Tanking

Under BS8102:2022 code of practice, barrier protection is classed as type A waterproofing for the protection of below ground structures against water from the ground. Concrete builds that are below the water table are prone to free water finding a way into the subterranean room through any gaps in the waterproofing. For older buildings that aren’t constructed under the new regulations, the structures will not have the same level of waterproofing from external barriers. Type A helps protect the concrete from water and moisture that enters the space with a view that this free water can then be drained away to prevent damp.

Liquid Waterproofing Membranes & Coatings

Cementitious waterproof coatings protect against ingress. In an event where there isn’t sufficient structural protection, applying a coating to the concrete floor will shield against penetrating water. These coatings are layered on the surface using specialist tools to ensure an even and complete coat. This coating bonds to the concrete, hardening to form a tanking membrane.

Our concrete specialists use a combination of products to achieve the highest level of waterproofing for concrete structures vulnerable to water ingress. We use cementitious coating 851, Hydrocoat Tanking slurry and Vandex BB57 for different purposes to ensure complete protection.
