Penetrating Damp

We all know what the British weather is famous for. Homes in the UK have a tough time keeping it out. If you think you may have any problems with dampness in your walls internally or externally or maybe you have a number of bricks on external walls that are spalling ( the face of the brick crumbling) or you can see mortar missing or falling out of the brick joints.

I will try to give you some insight to the problems.

Penertrating damp in a wall is usually from a source such as wind driven rain causing moisture to enter the structure in a horizontal direction. Gravity may cause the downward movement of the dampness having an effect that the damp is entering at a lower point than the actual problem. (Penetrating damp should not be confused with lateral damp.)

 

Penetrating damp may be from a number of sources, defective brickwork or faulty pointing rain water goods defective flashing's. Penetrating damp has been proven to be responsible for a high percentage of dry rot attacks in buildings. Penetrating damp can create isolated patches of dampness that increase in size after periods of heavy rain and can dissapear in long dry spells of weather, if the problem is visible internally plaster work appears cracked and blown or wall paper or paint can appear loose or flakey, mildew and black spot mold may appear sometimes the dampness may not be visible as the water is absorbed into timbers maybe structural which will act like a sponge.

Repointing

When repointing  mortar should never be stronger than the bricks in this context stronger does not mean it's load bearing capacity, but the mortars hardness and permeability hard dense mortar should not be used to surround porus bricks in such brick work rain water wets the bricks but the impervious mortar stops the water diffusing and prevents brick work drying out freely idealy both the brickwork and the mortar should have a similar porosity.
