Left untreated damp can cause structural problems to your home, can have adverse affects on your health and can make your home difficult to sell or remortgage.The solutionThe innovative method, by Holland Damp Proofing, is completely natural and doesn't use harmful chemicals like other traditional damp proofing methods. Unlike chemical damp proof courses, which break down and need re doing every number of years, the Holland Damp Proof System® is a permanent solution.By using specially designed bricks fitted into the outside wall, air is allowed to flow into the air chambers of the system and out again. On its way through the inside of the wall, this airflow causes moisture to evaporate, therefore drying out the wall.
