Damage to structures is often caused by human error or low-quality materials. To solve the problem of low quality, both from a human and material perspective, there are a few tips to make up for big expenses by increasing the strength of the building structure. One of the main problems is sinkage. The soil layer under the foundation is less dense or hard so that it is unable to support the load above it. Soil changes its characteristics due to natural events such as floods, earthquakes. You need to create a new foundation that is close to the foundation that fell. The goal is to share the excess load. Compact the soil surface under the new foundation manually or with the help of a stamper machine so that the soil bearing capacity increases. Or the easiest way to fix the problem is by underpinning method that is provided by underpinning services in Melbourne.
One of the signs of sinkage is cracks on the wall. Structural cracks in the beam have a vertical or diagonal pattern, besides, there are also hair crack patterns. Cracked concrete blocks can be categorized as structural cracks consisting of flexural cracks that have a vertical or upright pattern. Usually caused by loads that exceed the beam’s ability and shear cracks that have a diagonal or sloping pattern, which usually occurs after a bending crack that has a vertical pattern. Shear cracks can also occur if the beam is subjected to earthquake forces. Besides, the cracks of the blocks can be caused by incomplete work processes. Small cracks or hair cracks, mostly caused by environmental influences. It generally occurs because the blocks are exposed to sunlight and rain.
For concrete blocks where there is a wall underneath, additional columns or small posts can be made around the crack. The function of this column is to support the beam and help distribute the load to the bottom or foundation. For concrete blocks under which additional columns are not possible, first injected with epoxy in the cracks, then enlargement of the beam dimensions with external reinforcement. For small cracks, simply patch with plaster. The goal is that the steel reinforcement is not in direct contact with outside air which can cause rust.
