However, as the concrete crack widens gradually, it would ultimately become a structural crack and cause structural problems, unless the crack is repaired. When cracks on a horizontal concrete surface such as a concrete slab get widened to a degree of causing a tripping hazard, it is considered a severe crack and needs immediate repair.
In construction, the crush resistance of building materials like concrete, steel, or bricks must be understood to ensure that structures can support the intended loads. Overall, crush resistance is a vital parameter that …
Robore Cuts are one of the only Concrete Demolition companies with a fully equipped mobile workforce across the UK. Find out about concrete bursting now.
Hydraulic and chemical pressure bursting break up concrete structures with a minimum of noise and flying debris. Both methods work by applying lateral forces against the inside of holes drilled into the concrete, and can do virtually any job other demolition methods are capable of.

Concrete's direct tensile strength is much less than its compressive strength—about 10%. So when it's pulled too hard, it …
After concrete is placed, the concrete increases in strength very quickly for a period of 3-7 days. Concrete which is moist cured for 7 days is about 50% stronger than uncured concrete. Water curing can be done after …
Poor Workmanship – Using more hand trowel actions while placing the concrete leads to the improper settlement of concrete and raises cement paste to the surface and makes water bleeding. It later forms the crazing. Excessive Use of Cement – To give a smooth finish on the concrete finish, labours try to sprinkle cement on the surface. Later ...

After concrete is placed, the concrete increases in strength very quickly for a period of 3-7 days. Concrete which is moist cured for 7 days is about 50% stronger than uncured concrete. Water curing can be done after the slab pour by building dams with soil around the house and flooding the slab. The enclosed area is continually flooded with water.
Pipe Bursting Methods Static Pipe Bursting. Static pipe bursting is a method that utilizes a pulling machine situated at one end of the pipeline.
