Why Does My House Have Cracks In Melbourne

CAUSE OF WALL CRACKS

Building Inspection Defects - cracks to my walls

CRACKS TO WALLS MELBOURNE
You are noticing cracks to your internal walls and they are becoming larger every year or your external brick walls have cracks which are more than 5mm in width then you may have a structural issue that requires identifying the cause.

Don’t ring a tradesman to repair that internal crack or enlist the help of an underpinner-Stop you need to first identify the cause and to then rectify as the cracking will not stop if you don’t find the cause first.

House Inspections are experts at identifying the cause and they will refer you in the right direction with the right trades people to use knowing that you will not be taken for a ride and being scammed in the process.

Yes there may be structural issues at play and you therefore require someone with specialist knowledge before your house crumbles before your eyes.

Cracks to walls are normally caused by your foundations shifting/moving due to subsidence or heave caused by changing soil movement conditions.

.Your house is sitting on foundations and with changing environmental conditions you will start noticing cracks to your brickwork and internal cracking to your plaster boards you may also notice your doors not closing like they used to.

Your floorboards may creak when walking through the house or you may notice bounce to certain sections or your windows are becoming hard to open .

Most of these issues are caused by water or trees being planted to close to the house with changing water content affecting reactive soils .

You will notice cracks internally to cornice mitres or along wall junctions but these are just settlement cracks that are easily repaired, if your not sure send us some photos and we will help you to identify whether the cracks are normal that you should not be worried about-NO CHARGE FOR ADVICE

One of the most common factors affecting foundation performance is trees.

Common guidelines for tree and shrub placement on reactive sites are to keep them well away, at least their mature height distance, from buildings.

How close is too close? This depends upon the species of planting, root distribution, soil, plant size and maturity, depth of foundation, availability of water and many other factors.

You will have to take a guess at where the tree may look for water and in this case im assuming its towards the foundations

The age of the house plays a big factor but I have also seen significant cracks to walls in house that are only 5 years old ,so poor workmanship will contribute to this problem also due to negligence from the plumber or other trades.

Trees and shrubs most commonly cause settlement of the part of the building Closest to them and outward rotation of strip footings towards the plant.

Watering, particularly over-watering of plants can cause heave or in extreme cases saturation settlement.

If a large tree is removed, the foundation may heave and re-bound, perhaps leaving part of a building permanently slightly high-no trees have been removed

As many soils change in volume with moisture content this is a key property.

Granular soils can settle due to increased moisture lubricating their particles and allowing them to rearrange.

Clay display reactivity and can also become soft when extremely wet.

Moisture moves through soils or accumulates for many reasons and is a major factor in foundation performance.

Strip footings, are susceptible to rotation from differential moisture in expansive clays and settlement at corners

Strip footings are often combined with stumps internally which can settle over time.

When footings move, they may heave or settle, settlement is generally more common.

Clay foundations that swell when they get wet and shrink when they get dry are a common source of foundation movement and building distress.

There so many causes why buildings crack and without a proper intensive inspection it would be impossible to predict the eventual outcome.
