Damp issues can arise within walls when there’s a lack of an effective damp proof course or when damp proofing is overlooked during initial construction or renovation.
Detecting rising damp in a property can occur through a Building Survey, involving tests at the base of damp walls. In more severe cases, where damp has been untreated, visible patches and hygroscopic salts on wall surfaces may appear over time.
Addressing rising damp requires removing wall plaster, typically up to one meter or higher, depending on masonry salt content and other factors. Installing a new damp proof course within affected walls is essential for property protection.
Damp Proofing Walls: How is a damp proof course installed? Damp proofing walls by RB Damp proofing involves two critical elements. Ensuring the correct installation from the outset is crucial to prevent exacerbation and future costs. While consulting RB Damp damp proofing expert is advisable, here is a basic process:
-
Install a damp proof course by pattern, drill the masonry at the base of damp walls, and inject a specially formulated solution until full impregnation is achieved.
-
RB Damps injection process, with low odor, forms an impervious barrier to rising dampness, preventing moisture from the ground. Adjacent walls are isolated using a vertical damp proof course as part of the treatment.
Used alongside a specialized waterproof rendering system, this offers a reliable and cost-effective solution, ensuring damp walls are no longer a concern.
The new damp proof course prevents moisture rise, initiating the drying process. However, due to ground salts, complete drying requires removing existing plaster and replacing it with a salt-retardant render, such as a waterproof rendering system.
Waterproof rendering system: Benefits include perfectly batched renders, with proportions of sand, cement, lime, and water proofers in factory conditions. After applying the waterproof rendering system, a top coat skim plaster provides a smooth finish.
