The owners had bought an area of land to build Britian’s first ‘healthy home’, the reason behind this was to ensure the safety of their two sons who suffer from life threatening allergies.
Materials used and air quality had to be as healthy as possible.
Due to the land restrictions and neighbouring properties the design had to be a single storey out of the other properties line of sight.
This meant the owners had to go underground.
The project itself can be seen on Channel 4’s Grand Designs.
Renlon tendered the works for O’Sullivan Civil Engineering to undertake the waterproofing of the large basement.
Delta Cavity wall membrane to the walls and Delta Cavity floor membrane to floors was specified in the design incorporating modular and perimeter drainage and a sump pump chamber.
The waterproofing design and installation had to be appropriate and the treatments specified had to protect the basement against the potential risk of water penetration.
A type C Cavity wall and floor membrane was installed and forms a waterproof inner lining to the walls and floor.
This then collects any potential water ingress diverting it to a sump from which it is pumped away.
