Dampcheck Plus (25 L)
Dampcheck Plus is a BBA-approved DPC fluid that is supplied ready for use. It is injected into holes drilled in masonry to form a damp proof course (DPC). Injection can be carried out using an electric pump or by using funnels (gravity feed method). Dampcheck Plus is non-flammable and is silane modified – allowing for faster injection times and more thorough treatment compared with standard DPC injection fluids. Because it is solvent-free, it does not cause a lingering “solvent odour.”
Dampcheck Plus has a multi-component formulation which means that it develops initial water-repellency quickly, but also allows further diffusion to form a more evenly distributed damp-proof course.
High Performance Damp-Proofing Fluid
Consideration should also be given to the use of Dryzone damp-proofing cream which can be installed more quickly than Dampcheck Plus and virtually eliminates the spillage and mess problems associated with the injection of DPC fluids.
Despite these advantages, Dampcheck Plus has now been largely superseded by Dryzone Damp-Proofing Cream which is faster to install and does not require an electric DPC pump.
As with all remedial damp-proofing systems, it will be necessary to remove and replace any salt-contaminated plaster. A 3:1 sand-cement render incorporating Renderguard Gold is usually used for this purpose. Where the use of a hard sand/cement render is not desirable, another option is to cover the wall using Oldroyd Xp Plaster Membrane. This allows a wider range of plasters to be used.
