New-Build Terrace Waterproofing

Summary

Newton Specialist Basement Contractor CCL installed Newton Acriflex Winter and Newton NuSeal-LM to a new podium deck/balcony and terrace in Surrey as part of a comprehensive waterproofing system.

The Project

Redbridge Building Contractors commissioned Newton Specialist Contractor CCL to design, supply, and install a comprehensive structural and terrace waterproofing system. This was for their luxury new-build property in St George’s Hill, Surrey.

CCL installed the Newton System 500 internal Type C Cavity Drain Membrane system to the Type B reinforced concrete box structure to provide a combined waterproofing solution as recommended for habitable accommodation in accordance with BS8102:2009. Moreover, the internal drained cavity system offers the ultimate contingency plan to capture any water ingress that may occur through the joints in the concrete structure. CCL installed the Newton Titan-Pro sump system, complete with full battery backup protection.

The Solution

Specifically, CCL installed Newton Acriflex Winter as the waterproofing solution to all the interlinked balconies and terraces.

Applicators apply Acriflex, a twin-component flexible acrylic waterproofing system, by roller to the mechanically prepared concrete. Once prepared, the team roller-applied Newton NuSeal-LM in two coats to serve as a primer and vapour barrier. Next, the Acriflex was applied and Newton 207 DeckDrain double-cuspated drainage membrane was applied over the Acriflex to protect the waterproofing layer and move any water to designated drainage outlets designed within the podium deck structures. Lastly, the team laid stone paviours on a 50 mm sand blinding layer to complete the terrace areas.

Acriflex Winter, NuSeal-LM and 207 DeckDrain were ideal for this terrace waterproofing project.
