What causes cracks in concrete?
Many factors may cause concrete to crack. However, rapid loss of water from fresh concrete is one of the leading causes of cracks in concrete. The rapid absorption of water from formwork or aggregate can also cause concrete to crack. In addition, cracks in concrete may also be caused by bleeding and sedimentation, negligence, poor workmanship, and content of cement.

To repair cracks in concrete, you must first clean the cracks, choose a suitable sealant, apply the sealant, and leave the sealant to cure. Concrete crack repair requires skill, practice, and an excellent eye for color matching.
Are all cracks in concrete a problem?
Cracks in a building are not necessarily dangerous, or a cause of concern; some cracks are relatively harmless. Different types of cracks may appear in concrete, including plastic shrinkage, expansion, heaving, overload, and subsidence, among others.
Plastic shrinkage occurs when concrete is still full of water and has not hardened. As the concrete loses moisture, it shrinks and may crack to relieve tension. Plastic shrinkage may not be a threat to a concrete structure.
Expansion occurs when concrete expands due to heat or hot weather and pushes against objects in its path. If the objects in its path cannot expand, it cracks. Thaw and freeze cycles, as well as growing tree roots, can also cause cracks to develop in concrete, a process known as heaving.
Settling occurs when the ground under concrete becomes soft as a result of saturation. As the weight of the concrete compacts the soil, cracks could develop due to uneven settling of the ground underneath.
When you should be concerned
Cracks in concrete become a problem when they become wider than an eighth of an inch. Water may seep through such cracks and cause structural damage. Water seepage may reach the rebar and cause it to rust, which causes the steel to expand. The expansion of steel may cause concrete to crack further and weaken the structure.
If you see cracks on your property, call us to come and assess the condition of your structure. A seemingly harmless crack can cause significant damage to your property.
