Case Study: Damp Proofing Works at Worcester Park

Project Overview

We were requested to inspect a large room in Worcester Park that had fallen out of use due to persistent dampness. The damp was primarily visible at the base of the walls, and the air in the room felt damp as a result. Following our initial assessment, we diagnosed the problem as rising damp. This diagnosis was subsequently confirmed by a specialist damp surveyor.

Preparation and Damp Proofing Process

To address the rising damp, we began by removing all the old plaster back to the brickwork to a height of 1,200mm around the entire room. This ensured that all potentially affected areas were exposed and could be properly treated.

Next, we drilled into the brickwork and inserted Dryrods. These rods are designed to release damp-proofing chemicals into the bricks, establishing a new, continuous damp-proof course to prevent future moisture ingress.

Rendering and Finishing

Following the damp proofing treatments and preparation, we applied a scratch coat composed of sand and cement. While this coat was still wet, we embedded render mesh to reinforce the surface and prevent cracking. After the scratch coat had set, we applied a top coat and rubbed it up to prepare the surface for the final finish.
Finally, we skimmed all the walls up to the cornice, providing a smooth and ready-to-decorate finish.
