Flexcrete Structural Waterproofing of Basements

Finding the Right Concrete Waterproofing Solution

For both refurbishment and new build works, Flexcrete offers a wide range of impermeable, sulphate resistant, cementitious waterproofing coatings for structural waterproofing of below ground and water retaining structures. Our concrete waterproofing range includes mortars and coatings that are Regulation 31 approved by the Drinking Water Inspectorate (DWI) for use in contact with potable water.

With rising water tables around the world, there is increased demand for reliable waterproofing of basements, tunnels and other underground structures, many of which were not originally designed to resist water infiltration. Post construction underground structural waterproofing can prove difficult and costly, but Flexcrete’s thin film cementitious coatings provide the ideal, long-term, cost-effective waterproofing solution. Able to be applied to damp surfaces, they resist both positive and negative water infiltration at pressures up to 10 bar. With water-based, non-hazardous formulations, they rapidly cure without the release of strong odour or hazardous solvents. Furthermore, our concrete waterproofing products are ideal for sealing secondary containment facilities or bunds to eradicate the possibility of aggressive substances leaking from storage tanks and silos into groundwater.

Concrete Deck Waterproof Protection

Waterproof deck protection, which extends beyond internal floors to include roofs, balconies, walkways, stairwells and car parks, has been one of our core market areas for many years.

Our unique epoxy and cementitious modified polymer coatings offer years of effective resistance to abrasion, water ingress, chloride ion penetration and aggressive chemicals in areas subject to extreme trafficking, including loading bays. Applied to saturated concrete, they are impermeable to water under 10 bar pressure and cure rapidly to withstand foot traffic just six hours after application. Excellent freeze-thaw resistance prevents spalling of the concrete surface. Furthermore, when used internally as a levelling waterproof layer on damp substrates, resin, sheet vinyl or carpet flooring can be installed without waiting 28 days for concrete to cure.
