Newton Waterproofing Systems expands its existing Damp Proofing System with the addition of these three new products, the range now contains a comprehensive choice of products that can be utilised in different combinations dependent on the scenario.

For example, Newton System 800 damp proof membranes can be used with Newton 804-DPC as an alternative to rendering with Newton 808-RA.

Collectively, the new products make it possible to deal with all forms of damp, from rising damp to penetrating damp, hygroscopic damp and condensation, and always providing the client with a BBA certified solution.

Dealing with rising damp

Once a survey has identified rising damp, the best method for stopping it is a two-part process that deals with both the source of the rising damp, and the potential for internal issues caused by the salts. To prevent rising damp in new builds, the BBA certified physical damp proof membrane Newton 809-DPC is installed.

However for remedial rising damp situations this process is too expensive and impractical, so the best method is to use Newton 804-DPC to convert an existing mortar course into a new DPC. This high strength damp proofing cream works by diffusing along the mortar course before curing into a breathable and water-repellent barrier that stops the rising damp.

Next, re-plastering internally is crucial to tackling hygroscopic damp. Newton 808-RA is therefore employed as a salt resistant render additive that prevents the passage of residual moisture and hygroscopic salts from the underlying masonry to the new internal surface. Both Newton 804-DPC and Newton 808-RA are also fully certified by the BBA.
