Delta Membrane Systems has provided a detailed waterproofing solution for a new build luxury property in North London, providing almost 17,000 sq ft of accommodation, set over four floors.
High volumes of hydrostatic water pressure was bearing on the structure, which was causing the property to suffer severe water ingress through construction joints. The project, due to its size and complexity was set into phases. The first phase was to ensure the property was made safe from electrical dangers.
The second phase was to stop the water ingress. Once the structure had been stripped back to its concrete core, the water ingress to construction joints was addressed. Delta technical consultant Paul Callaghan recommended using the Koster brand of concrete repair solutions to limit and slow down the water ingress experienced. Paul’s first recommendation was to use Koster KD 2 Blitz – waterstop to the construction joints. Koster KD Blitz Waterstop, stops active water ingress and safely seals off pressurized water from the negative side.
Once the construction joints were sealed Paul suggested applications of Koster NB1 and Koster Repair Motar Plus. KD Blitz was added as a secondary line of defence with NB1 coated to external walls throughout the basement structure to stop any water ingress (“locking down the structure”).
Paul’s on site attendance and eye for detail were exactly what was needed for this project. Paul created a waterproofing system which would allow for the issues caused by the hydrostatic water ingress to be addressed. By incorporating Paul’s waterproofing solutions, water ingress was nullified.
