EXTERNAL INTERNAL WALL CRACKS MELBOURNE

 

CRACKS TO WALLS MELBOURNE

While people usually ignore cracks in building interiors and exteriors, professionals know that these can lead to damages if left unchecked for an extended period. If you are looking to buy properties that are relatively aged, hairline cracks may be unavoidable. However, there’s a huge difference between hairline cracks on a facade and structural cracks.

Hairline cracks can be repaired easily; structural cracks cant be repaired but not as easily. You will need the help of a building house inspector in Melbourne  to assess the situation and handling the repairs for you when it comes to structural cracks. Otherwise, the structural integrity of the building you’re looking to purchase will be compromised.

 

Cracks to walls may indicate minor movement with the house which is normal but if the cracks are 5mm wide or wider then you may have a structural issue that will require urgent rectification,

Doors and window no longer closing in there frame will indicate either heave or subsidence to the foundations due to changing conditions to the soil below due to water.

Many old homes still have earthenware piping systems  that are prone to cracking or collapsing over time and storm water going to the foundations will cause many of the external/internal cracks.

I have also seen houses only 4 years old with PVC pipes being  blocked with tree roots and cracked causing water to run off under the slab destabilizing the soil and the foundations.

 

I always recommend before buying a house to conduct a CCTV survey scan of all drains as this defect only could set you back thousands

Problematic wall cracks will typically start at windows, doorways or corners of buildings. Generally, smaller hairline cracks are not cause for concern. These are usually the result of seasonal expansion and contraction of soils beneath the building over time, and can be easily patched and re-painted.

Large cracks appear because the property’s foundation have shrunk or lost there strength, causing all or a part of a building to sink, known as subsidence. This usually happens because the moisture in the soil beneath the foundations has caused the soil to subside therefore causing the wall to move and crack

The best long-term solution for fixing large cracks is to lift, re-level and re-support the building. This level correction process is called underpinning. As the building is re-leveled, the cracks in walls may close or become smaller (readying plaster or render walls for fine patching and repainting)

. Windows and doors will also usually begin to work properly again. Traditional underpinning or level correction methods involve excavating or digging up parts of the foundation, pouring in concrete, waiting for it to set and then jacking up the building off the concrete blocks.

Common types of Brickwork cracking include:

  • Vertical cracking
  • Horizontal cracking
  • Stepped cracking
  • Diagonal cracking
  • Togged cracking

Using these factors alongside measuring the cracks in the bricks make it possible to determine a rating of the severity of the cracking, and accurately attribute the cause of the cracking in most cases.

 

Frequent causes of brickwork cracking are:

  • Sinking foundations usually caused by environmental factors which have caused the building to sink over time, and caused it to pull away from the rest of the building.
  • Over time, the force of built-up soil, tree roots, and water movement can affect a retaining wall and cause brickwork to crack.

Our building inspectors provide a severity assessment which considers the location, number, length, and width of the cracks to identify if cosmetic, minor, or remedial work is needed or if it is more serious, and a structural engineering solution would be needed to determine an appropriate course of action to prevent further cracking, and offer a permanent fix.

A building inspection which focuses on cracks in brickwork will help to put your mind at ease and stop you stressing.

A qualified building inspector will carry out a thorough inspection and provide you with a written and insured report which details the type of cracking found, the cause of the cracks, and also some recommendations about how to repair the cracking.
