Settlement and other foundation deformations are frequent problems, which can be associated both with errors made during the design and construction, and with violations of the conditions of building operation. They significantly reduce its life, and lead to the destruction. Foundation leveling will help make things better. This is the process that includes the use of various technologies, allowing you to raise or lower parts of the foundation to reach the required level. We level the foundation using modern methods of deep soil injection under our own brand GeoResin Deep Stabilization and GeoResin Slab Lifting.
When you may need to level the foundation
The main causes of base deformations are:
- · design errors due to the incorrect building weight distribution on the base;
- · soil instability or inhomogeneity;
- · water impact;
- · violation of building rules and regulations;
- · excessive loads during natural disasters (earthquakes, floods, strong winds).
Besides, these factors can interact, aggravating each other.
Base settlement and other deformations can occur both in the horizontal plane and in the vertical one.
Foundation Leveling Methods
Today, various technologies and methods are used to strengthen the foundation. The choice of method depends on the type of foundation, the type of deformations, and the reasons that caused them. Here are some of the methods used to strengthen foundations:
- 1. Additional supports arrangement help to disperse the weight of the building on the base and prevent further movement.
- 2. Replacement of damaged foundation sections in case of serious damage. This can be a complex process that involves lifting and maintaining the building during replacement.
- 3. Increasing the bearing area of the foundations by installing concrete fastening lugs, deepening the foundation, placing a concrete pad under the foundation. In these cases, at first formwork is installed to form concrete structures, which is then poured with building concrete mix.
- 4. Relieving existing foundations from lateral pressure, transferring loads from foundations to piles to improve soil conditions and prevent problems from reoccurring.
- 5. Fixing the foundation base soil by injecting special polyurethane foam compounds into the soil under the foundation – a method that is used to level and raise foundations, strengthens the soil, stopping the foundation sagging. This is a modern, non-invasive method that does not take much time to complete the work.
Stages of work on the foundation leveling
Regardless of the method chosen, the base leveling process includes the following steps:
- 1. Assessment of the foundation and base state, as well as identifying the causes of the foundation deformation.
- 2. Work planning. Based on the assessment of the foundation state and the causes of its deformation, the specialist develops an action plan to stabilize the foundation and level the foundation, which includes the choice of the method.
- 3. Preparation of the site that will be used to perform the work. This may include debris clearing, constructing temporary supporting walls or bearings, and installing equipment.
- 4. The process of the base and foundations strengthening. It may include various steps, depending on the chosen method.
- 5. Restoration works after the foundation strengthening is completed. This may include the foundation backfilling, restoring the blind area around the perimeter.
