RISING DAMP SERVICES
RISING DAMP
Explained
Rising damp is when moisture in the earth soaks through the foundations and walls of a house, rising up through the layers of bricks and causing damage.
Houses are built with a damp proof course (DPC),just above the floor level to prevent moisture rising up, but if this has failed or the property did not have a damp course, then rising damp will occur.
Also it may be due to poor building work, lack of building maintenance or deterioration of building fabric in old buildings.
Rising damp will generally appear along the base of a wall and their are a number of signs to look out for.
RISING DAMP
Signs
- Damp or decaying skirting boards
- Salt stained plaster
- Dis-colouration & Staining of the base of the wall
- Peeling paint or wallpaper
RISING DAMP TREATMENT
Replacing DPC
- As physically replacing a DPC is a difficult process that would involve a huge amount of structural work, the only way to treat rising damp is to install a chemical damp course (DPC).
Pre-Determine Depth
- Depending on the thickness of the wall (single or double walls) holes are drilled in the mortar course of external or internal walls to a predetermined depth and at the correct level and spacing between holes.
High Strength Silicone Based Cream
- The holes are then injected with a high strength silicone based cream. Once injected the cream diffuses along the mortar course before curing to form a water repellent resin.
Removal of Contaminated Plaster
- All the plaster that has been damaged or that has been contaminated with salt will be removed and replaced with dampproof plaster. This specification uses a modern formulation of breathable damp and salt resistant plaster mixed with salt inhibiting additive.
Time to Dry Out
- Once the replastering has been completed and the walls have been given the correct amount of time to dry out (10-14 days) it is then possible to reinstate the skirtings and redecorate the wall.
