Project: A large 27,000 sq ft Country house development in Surrey.

MacLennan were asked to provide design for the new build basement waterproofing and installation of the cavity drain waterproofing systems for this very large new build development in Surrey.


This very large house is a high end residence on Wentworth estate. The new build basement waterproofing system is essential for this type of construction as it will house the gym, swimming pool , garaging , plant rooms etc.

The new build basement waterproofing was the most critical item in the design and installation.

MacLennan supplied design expertise and detailed all aspects of the new build basement waterproofing with the Architect, engineer and contractor.

MacLennan have worked with the design team on multiple successful projects of this type over the last 5 years.

Method


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 MacLennan 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.

History of Wentworth Estate


"In 1912 builder W.G. Tarrant started constructing St George’s Hill in Weybridge, a development based around a golf course that he envisioned as the ideal residence for the wealthy.   Here the successful businessman or professional could find privacy, quiet, natural beauty and easy access to excellent sporting and exercise facilities.   The success of this venture prompted Tarrant to acquire the development rights for the Wentworth Estate in 1922.  As in each of his major developments, Tarrant wished to create an exclusive estate with covenants that ensured that it would be preserved. Unlike St George’s Hill where each property was built on at least an acre of land, Tarrant opted to have at Wentworth houses of a broader range of size and price. The eastern area, near the village of Virginia Water and its rail station, would contain shops and smaller houses. To the west around the golf course, the plots of land and the houses would be larger. The covenants on the deeds forbade the subdivision of plots and the redevelopment of the houses was restricted to ensure that the exclusive nature of the area would continue."
