Stonehouse delivered an exceptional waterproofing design and installation for the client, who now has a watertight and guaranteed two-level basement beneath their home, that they can enjoy in full for the first time in many years.
"This was probably the most technically challenging project Stonehouse have ever undertaken. But with clients who wanted no future risk of water ingress, we were able to design and intall a robust, durable solution utilising the full range of Newton waterproofing products to prevent water ingress from all conceivable directions. As a result, the client can finally enjoy the vast space below their house with the reassurance of our long-term guarantee." Graham Stone - Managing Director, Stonehouse
