The causes of cracks in your walls

It doesn’t matter how strong a building is. Time will eventually get the better of it. Standard maintenance can help, but it’ll only take you so far. There are other solutions available though. We can use our brick and masonry repairs service to assist you.

You must take one crucial step before performing the repairs on your bricks. You need to figure out what is causing the cracks.

Thermal movement

This is one of the most common causes of cracking. It occurs because substances contract and expand differently. If one expands and the other does not it can create a crack.

Normally, you discover this kind of movement at the juncture between separate mediums. One example would be where aged solid brick walls encounter blockwork ones. Great stretches of wall made from one material are also problematic. They’re capable of producing narrow, vertical thermal movement cracks.

Differential movement

You normally find this where fresh extensions abut an old property. Said extensions possess deeper foundations than normal. These movements also happen when there are porches or bay windows with shallower footings than the main structure. There are different foundation loadings and depths. As a result, the footings will move at conflicting speeds. The stress causes the cracks.

Water and corrosion

You should watch out for both of these too. Water can penetrate a wall and freeze shortly afterwards. This action can open cracks. Over time, it can also lead to metal components rusting and expanding. Rainwater might access a crack and cause an old steel lintel to rust. The resulting expansions can force the neighbouring brickwork into moving.

At Churchill Concrete Technology, we prefer to look into the origin of the damage before progressing. This makes it easier for us to decide what the best course of action is. We do this for every project.

Our brick and masonry repairs offer wonderful results. They will improve the aesthetics of the property and also provide better protection for the future. If we can help you at all, please get in touch.
