How does a damp inspection work

The first job is to check the levels of damp within the walls with a damp reader or moisture meter. The prods in this example go in to plaster and a reading is displayed. The most common building material to be damp at a low level is plaster, at 4% it is considered saturated with moisture, where as mortar is considered dry at 4%.


Repairing the wall and damp proofing

Once the source of damp has been confirmed, in this case it is penetrating damp from outside and a gutter leak, the damaged mortar is removed back to the brick. Mortar repairs are then carefully undertaken to stabilize the bricks.

To help prevent further damp from coming through, a damp proof cream called dryzone was injected into the mortar (the pointing not bricks) on both the external and internal wall.

In the final stage moisture resistant boards are attached to the internal walls with a specialist bond to prevent further moisture reaching the boards. Then a final skim of plaster is added along with skirting ready to be painted.
