Methodology

The basement was built of poured concrete. MacLennan installed a full Type C cavity drain system internally, which in turn would rely upon a sump and pump system to maintain drainage. To the Ground Floor Terraces we applied the Polyprufe system. At the junction between the top of the wall and the deck and the top of the wall and the house MacLennan detailed and installed our Polyprufe top of wall system.

Result

The new build basement waterproofing was designed, supplied and installed by MacLennan Waterproofing. The system is guaranteed for a period of 20 years. The guarantee is covered by MacLennan warranties and 5 million PI. The Project was completed on time and within budget.
