Cracked Walls

Are cracked walls something you should be concerned about?

The cracking of walls is a warning sign of structural damage that should not be ignored.

Wall cracking is often due to subsidence causing structural movement and possibly damage. 

Wall crack repairs are common in properties in most metropolitan regions of Australia, particularly Sydney, Melbourne and Brisbane.

Whilst hairline cracks in walls are sometimes superficial, brick wall cracks and cracked walls often indicate sinking foundations and are a serious structural concern often requiring underpinning.

If your house is cracking and wall cracks are left unattended, this can cause further structural damage, endanger tenants and devalue your property.

What to do if your House is Cracking?

If your house is cracking Raise and Relevel has specialised polyurethane resin injection methods for wall repairs and underpinning properties or assets of any size. 

Raise and Relevel ground surgeons all have over 15 years of experience to provide you advice (not sales) about repairing your wall cracks and undertaking structural repairs.  

If your house has cracks in its walls internally or externally, your house may require to have its foundations repaired, have the supporting ground improved or concrete footings relevelled

As your house is re-levelled, wall cracks will generally close, fixing a crack in the wall and making it ready for cosmetic repairs. 

Importantly, after Raise and Relevel have completed polyurethane resin injection ground improvement, the causes of the structural issues associated with the cracking of walls are addressed. The ground is improved for the long term. 

What you need to know about Wall Repairs and Wall Crack Repairs

When your house is cracking there are three aspects to be considered for the wall crack repairs as follows;


Ground Improvement

Raise and Relevel ground surgeons use a polyurethane resin injection method of modern underpinning called Deep Injection. This dynamically compacts the ground under your house to increase the ground’s bearing capacity and achieve the ground improvement necessary to support your structure and eliminate subsidence long term.


Raising + Releveling

Once the ground has been improved, foundations and slabs are then raised and relevelled by our ground surgeons using other polyurethane resin injection techniques known as Deep Lifting and Slab Lifting.

These techniques will address the problem if your house or walls are cracking. Once undertaken, hairline cracks in walls and brick wall cracks should close and be ready for cosmetic repairs. 


Brick Stitching 

Before cosmetically repairing cracks in walls and brick wall cracks, Raise and Relevel recommend considering the brick stitching technique. Raise & Revel specialises in brick stitching, a cracked wall repair method that involves strengthening the areas where there are cracked walls and rebonding the sections of the walls that used to be monolithic.

Brick Stitching is a wall crack repairs method consisting of chasing out brick mortar courses intersecting the wall crack, inserting proprietary stainless steel tension rods and re-mortaring with a proprietary high early strength grout. 

When your house is cracking, our recommended way to repair cracks in walls is by combining brick stitching with polyurethane resin injection to provide a ‘belts & braces’ long term solution.
