Project Details

Project Name: Selwyn Village 

Applicator:  MPM Waterproofing Solutions   

Builder: Aspec Construction

Products Used: Volclay Range & Accessories 

Completed: January 2014

The Project 

Selwyn Village located in the Auckland suburb of Point Chevalier is owned by the Selwyn Foundation. The new village was part of a $50 million expansion of the existing 1954 retirement village increasing the village to meet the growing demand.


This Selwyn Village continuation consists of two separate buildings that are joined by a podium deck all with basement garaging. The project required a comprehensive solution, ensuring complete water tightness between the transition of buildings.

This project ran through two winters and therefore required a solution that would be able to withstand challenging conditions and membrane to be installed to both wet and dry substrates.


The entire Volclay Range was utilised on Selwyn Village for a range of reasons. Allco has a strong working relationship with Aspec Construction and the company had prior confidence in the Allco Product range and trust in the Allco TA Team.

Despite the proximity to Point Chevalier, there was no salt water contaminates in the soil and therefore regular Volclay Voltex was used. The benefit of utilising the Volclay Voltex membrane is the speed and efficiency of product installation and the ability to install to both wet and dry substrates on a wet site like Selwyn Village. Ultimately allowing them to meet their strict deadlines.  Waterstop RX was used in all cold joints to give additional protection, giving water tightness post construction.

One of the challenges that faced Selwyn Village faced inclement weather throughout construction. The heavy rain made the site ‘unworkable’ at times, however the use of Dewatering was required at various times throughout construction, with Aspec even installing a dewatering pump allowing MPM to continue installing membrane into lift pits. Post construction the site had a good drainage system making the surrounding area non-hydrostatic.

Despite the challenges of the weather, the construction of Selwyn Village was “very straightforward, easy construction and perfect waterproofing install”.

Allco conducted many site visits throughout construction providing onsite support, the clear, open communication with all parties resulted in high-quality dewatering and a seamless project with no issues post construction.
