Dysfunctional Foundation

As a building ages, it is inevitable that it's wrinkles will show. And by wrinkles, I mean deterioration. One of the most commons signs of old age is cracking. In this example, we see extensive cracking caused by a foundation shift. This shift can be triggered by many things such as inconsistent moisture levels in soil, tree roots or poor drainage. Check out the aftermath of a dysfunctional foundation...

​Suburb: CANLEY VALE

Project: Bellmont Façade Engineering was engaged to provide an expert opinion on building defects on a property located in Canley Vale. 

​

Cracking of vermiculite along roof and corners as well as evidence of water ingress along wall face

There are 13 units within this property. They all showed signs of aging, each with building defects. Some more than others. Issues present include;

• Brick façade cracking
• Poor drainage
• Foundational soils shifting causing cracks and water ingress, compromising structural integrity
• Extensive render delamination within some units

We concluded that the most likely cause of internal and external cracking throughout the complex is due to swelling and collapsing soils resulting in some washout of foundation soils, possibly arising from failed or cracked storm water pipes and/or natural flows of surface water.

All units are identical in construction and units with parallel front doors mirror internally

Cracking along underside of cornices.

Cracking along vermiculite showing attempts of sealing using silicone

Extensive delamination of render within living room.

Major horizontal cracking within upstairs bedroom.

Multiple areas of cacking on concrete slab in backyard extending across entire slab.

​
Recommendation:

• Underpinning works will be required to prevent further movement/separation.
• Delaminating render MUST be repaired.
• Investigate the delaminating wall cladding of the living room wall of units and repair brick or render if cracks are evident.
• We would recommend the cleaning and painting of eaves in order to cost efficiently upgrade the appearance of the building.

 
Status: Currently in tender stage of project.
