A large company with a office in CAULFIELD, VIC, requested our

assistance in solving the problem of damp walls.

During the examination, we found that the age of the building is about

50 to 70 years, the brick walls are of 270 mm thickness

(double brick with a cavity). The most inexplicable thing was that we

didn’t see air vents that are needed in the walls of this type.

Damp Proof Course was installed during construction and eventually fell into

disrepair and doesn’t fulfill its functions. As a result, the foundation and

brickwork absorb moisture from the ground and

this moisture rises up the wall due to capillary action.

If you don’t treat this moisture, it can erode building materials and cause a room to be uninhabitable as the amount of moisture will make electrical plugs dangerous.

This process is similar to that of putting a sponge in a bowl of water.

It can also lead to serious structural problems in

the walls of the entire building. Increased air

humidity can also lead to lifted condensation level

and mold growth with all the associated health

problems.

When we removed the existing render from the wall, we, surprisingly, found air vents.

Someone (not very smart and absolutely unskilled) covered all the existing

ventilation holes with a layer of cement render, eliminating the possibility for

the walls to “breathe”. This was the major cause of moistening the walls.

We strongly encouraged the customer to contact a ventilation specialist and

install ventilation holes in the walls.

Moreover, damaged render should be completely removed and the walls left

to dry for 4-6 months

Ventilation in double brick with a cavity is vitally important, so we

recommend periodically check and, if necessary, clean the Grill Vent in brick

wall from dust and dirt.

This will prevent moistening the walls and the problems associated with that.
