Adding Life to Concrete – How MARKHAM applied the holistic hydrogel waterproofing system for this apartment basement in Remuera, New Zealand.
OBJECTIVE
Remuera is an upmarket area of Auckland, NZ.
In this site, membrane installation was a serious safety issue due to limited access on a tight site. MARKHAM consultants were brought in at a late stage to offer a solution to this challenge. This was not without its initial detractors, and the architects the architects were hesitant.
SOLUTION
MARKHAM was able to assist with a holistic three-part system. The concrete itself was made waterproof by means of AQURON 300 admixture and AQURON 2000 spray-applied treatment. The penetrations and joints were sealed with CONQOR 47B delayed swell waterstop gasket.
RESULTS
The construction team were very pleased to find a holistic cost-effective approach that met the safety issues.
Due to the performance of this basement, the architects have become advocates for this system.
