Damp proofing is a term used in construction and refers to a process designed to make foundation walls waterproof and prevent damp and moisture passing through walls, to indoor spaces. Symptoms of damp vary, but will generally be visible by a cold, darkened area on a wall, which may be slightly wet to the touch. There may also be a musty smell and nearby carpets or furnishings may begin to stain as a result.
Without treatment, damp can spread and eventually lead to foundation walls and surrounding decor decaying.
There are 2 main types of damp: RISING damp and also PENETRATING damp. Both of which can be cured by us quickly, easily, without fuss and without mess.
1. For walls to left unpainted, we recommend our CLEAR COAT WATER PROOFER.
2. For walls to be painted, we recommend, NEVER PAINT AGAIN WALL COATINGS.
Damp can also be caused by poorly installed former damp proof courses (or their entire absence, in older buildings) and damage done through bridging – where floor or ground levels are changed. Damp can build up over periods of years, which is why some causes may not become visible for some time.
It can also be more of a problem with stone, brick and mortar – which are porous materials and will allow damp to rise upwards, carrying ground salts which can add to the dampness problem and break down plaster and decor over time.
Caught early however, damp proofing can be applied with excellent results.
A damp proofing course will involve a barrier being installed into a wall that resists the rising moisture using a capillary action – preventing what’s known as rising damp.
It will also have a damp-proof membrane to prevent similar passing damp on solid floors- known as DPM or DPC.
Our master builders will treat all surfaces and repair defects before the coating is applied. Different textures are available, from smooth, fine and coarse and the benefits are significant, including: A stop to condensation build-up in the home Reduced wind chill, leading to lower energy bills
