Read on as we discuss how to seal bricks from water to stop it coming through your walls.
There are a few different issues to blame when water is coming through brick walls.
First up is cracked render. As it covers the brickwork, render is the first line of defence for exterior walls on many buildings. If it’s cracked, it will let water through, which could eventually seep through the brickwork.
That leads us to the next issue – mortar. Brickwork is pointed with mortar to fill the gaps or joins between bricks. As well as improving their appearance, pointing is a vital feature to stop water coming through brick walls. When the mortar wears down or cracks, it provides an opening for rainwater to get through.
Finally, there’s wind-driven rain. As the name suggests, this is when rain is driven into your home by the wind – as opposed to simply falling down onto it. It’s most severe along the west coast of the UK, including West Scotland, the North-West and South-West of England, and the coast of Wales.
Because of its horizontal velocity, this rain can soak brickwork, which can lead to water ingress over time.
If you’re wondering how to stop water coming through brick walls, one approach is to tackle a specific problem area, such as damaged render or mortar. Repairing cracked render or repointing brickwork is sometimes enough to eliminate water ingress for good.
However, it could also be a recurring problem. If your pointing has worn down over time, what’s to stop it happening again? There may well be an underlying cause, like wind-driven rain. If this is the case, it’s best to opt for a water-resistant exterior wall coating such as SprayCork.
With a thin layer of spray-applied natural cork, your brickwork will be completely sealed off from the elements. That means no more water getting through, regardless of how driven the rain may get.
