Implications of Damaged Render

The most common cause of cracking and bulging, tends to be frost action on moisture trapped between the render and the wall.

This is why small hairline cracks should be sealed when they first develop, otherwise water penetrating through can freeze and expand, blowing the render surface loose — resulting in even larger cracks.

In some cases, missing lumps of render are also simply down to physical damage. Either way, once damp becomes trapped behind the surface it can penetrate through solid walls.
