Waterproofing a Luxury Basement Extension with Newton

Latest News Mon, Jan 24, 2022 12:55 PM

For this private property in South London, the luxury basement extension was a comprehensive project, extending below the entire footprint of the house and into the rear garden, and incorporating a swimming pool, recreational spaces, and a wine cellar.

Considering the nature of the project then, it was absolutely crucial that the waterproofing would adequately protect the luxury interior.

Managing Director Warren Muschialli comments: Considering the size of the basement area, the high water, the proximity to the River Thames and the fact that the structure was created using underpinning, the risk of water penetration in this basement was extremely high.

“We therefore called on Newton Specialist Contractor Stonehouse to provide a complete waterproofing system for the entire structure using the most failsafe solution, the Newton CDM System.”

Firstly, Stonehouse installed Newton 508 membrane to all internal walls and the floor, using Newton’s ancillary products to securely fix and seal the system.

Drainage channels were also created using Newton Basedrain, feeding into a sump chamber containing two NP750 pumps, a high-capacity model that is capable of removing large volumes of water.

Finally, where the basement extended beyond the footprint of the house, a liquid waterproofing membrane was used on the new external buried roof.

Stonehouse Managing Director Graham Stone comments: “At every phase of this project, we were aware of the presence of the River Thames. Water permeated throughout the excavation, and it was essential that the waterproofing of this substantial basement which also extends under the garden was reliable and robust.

“Stonehouse has worked on over 50 projects with this architect, always using Newton products that match our work in terms of both quality and craftsmanship.”

Warren also concludes: “We are extremely proud of the outcome of this project. Stonehouse are one of Newton’s oldest and most experienced specialist contractors, and they showed their expertise here by delivering a dry, safe basement for the client that could then be transformed into a beautiful new part of their home.

“Furthermore, the installation was backed by Stonehouse’s 10-year installation guarantee, for complete peace of mind.”
