How to restore your home after flood damage

Categories: Damp Proofing

Firstly, we recommend you use a post flood disinfectant and sanitiser, designed to santise and disinfect the entire area that has been exposed to bacterial contamination from the flood water. The sanitiser must be used before any cleaning and remedial work. The product is made with a highly potent biocide system, making it a strong and advanced solution, eliminating bacteria and a wide range of viral infections. The active ingredients have been tested throughout the world, with highly successful results. The sanitiser is sold in sachets and each sachet makes 25 litres of ready to use product.

Protect new surface finishes by isolating damp masonry walls. This can be achieved by hacking off the flood affected plaster and render back to the original masonry (normally brick).

Once you have removed this contaminated material you are able to install one of two types of isolating systems:

P-Seal Meshed Damp Proof Membrane is a 3mm meshed plastic membrane designed to isolate the damp background and provide an excellent ‘key’ for lime mortars, renders, plasters and dabbed plasterboard. The membrane is made up from individual 3mm studs that create an egg carton effect that means air can move behind the membrane helping to dry out the substrate. The membrane is resistant against fungi, bacteria and water and isn’t affected by minerals.The P-Seal 3 Mesh membrane is guaranteed to last 30 years before it suffers from deterioration, with a life expectancy of at least 50 years.

Permaseal Tanking is a completely waterproof coating that can be applied to the substrate to create a waterproof barrier. Once installed it should then be rendered with Permagard Renovating Plaster, a special render that contains waterproofing and salt inhibiting additives that stop salts or damp travelling from the background through into the final skim finish.
