Why is Damp Proofing Important
Damp proofing is a long term prevention against moisture decay in walls and foundations.
Prevents water passing through into interior spaces and can prevent timber decay and structural damage such as dry rot, wet rot and rising damp.
Damp Proofing- several ways including:
Damp Proof Course (DPC) This is a barrier injected into a masonry wall to resist moisture rising through the structure by "capillary action". the damp proof course maybe horizontal or vertical.
Intergral damp proofing
Involves adding materials to the concrete mix to make the concrete itself impermeable.
Surface coated with thin waterproof materials for resistance to non-pressurized moisture such as rain water.
Damp proof Membrane (DPM)- There are several types, for different purposes.
Plastic Dimpled Membrane - For laying onto damp floors, damp walls.
Liquid membranes - Brush onto damp walls and floors.
The source and type of dampness must first be determined before applying any damp proofing methods.
Longuard Damp Proofing surveyors have the knowledge and experience to determine the source and type of dampness and recommend the most cost effective treatment.
