The Newtonite System can provide an effective solution for rising, penetrating or hygroscopic damp in above-ground structures. Regardless of the scenario, the correct combination and application of products within the Newtonite System will provide a comprehensive solution.

Newtonite Internal Damp Proofing System 02

The Types of Damp

Rising damp is when water from the ground rises through the capillaries of brickwork, stonework, or mortar. This results in dampness to the internal wall finishes which can be unsightly, unhealthy, and can also lead to hygroscopic damp, where moisture-attracting (hygroscopic) salts are deposited within the fabric of the walls. Rising damp is most common in houses built pre-1925 when damp proof courses were not commonly installed.

Penetrating damp is the result of water penetrating horizontally from the exterior through the fabric of a wall. It can occur in any building and, as well as lowering the thermal performance of the wall, it can lead to other serious problems such as frost damage.

All forms of damp can cause problems to internal wall finishes and contribute to an unhealthy environment. A permanent solution, which combines the correct products to combat the source of the problem, is therefore essential.
