Types of Cracked Walls

Having cracked walls in your home could mean a lot of different things. On one hand, cracked walls can be a superficial, cosmetic issue. On the other hand, they can indicate deeper structural problems in your home. Your home could be sitting on shifting ground or failed house foundations. Cracked walls may even be because of the poor design and construction of your home. If you want to identify whether or not your cracked walls are actually rooted in deeper structural problems, look out for these 4 main types of wall cracks:

Cracked Wall Type No. 1: Stepped

If you have stepped cracks over 5mm, it’s highly likely your house foundations are no longer stable. Stepped cracks usually indicate a large part of your home is moving due to unstable brick house foundations or unstable soil below ground.

When you have stepped cracks, it’s likely you’ll also have cracked walls in other parts of your home. Stepped wall cracks definitely aren’t cosmetic or superficial. They should be investigated as soon as possible.

Cracked Wall Type No. 2: Internal & External

If light travels through your cracked walls or if you have cracks sitting above your doors and windows, your home is experiencing significant movement. Movement of your home can be caused by foundation failure, soil failure, additional loads and extensions to your home or even expansion of the actual brick.

If you observe light travelling through your cracked walls at any time of day, your home definitely has a structural problem.

Cracked Wall Type No. 3: Horizontal

Horizontal cracks are a tell-tale sign of localized movement in your home. While stepped cracks are usually an indicator of mass movement, horizontal cracks are an indicator of a foundational failure directly beneath the cracked wall.

Sometimes horizontal cracks just stop which means the wall is dropping down at a very localised and specific location. While horizontal cracks are a localised issue, the remainder of the structure will continue to sink and break apart if they’re not fixed.

Cracked Wall Type No. 4: Cracks in Corners

Over extended periods of time, clay bricks (natural product clay) expand. Some can even expand up to several millimetres per year. This may not sound like much, but over decades this expansion of the clay brick can create lateral force. This force drives the ends of walls into each other causing cracks to appear in the corners of your home.

Left untreated, lateral force can destabilise your home to the extent the walls can become free-standing and ready to fall over.
