Concrete slab adjustment


A concrete slab that is sinking multiples the risks of injuries and equipment failure thereby undermining your productivity and profitability. Sometimes, its also risks leading to structural weakening with disastrous consequences.

The GeoFix solution, which focuses on the calibrated injection of a high-resistance polymer formula, helps you to quickly eliminate these risks, without the high costs and major delays linked to the traditional demolition and reconstruction method. Slab jacking is a truly modern and efficient way to solve concrete problems at a fraction of the price.

What is concrete lifting and levelling?

Concrete lifting and straightening, as the name implies, consists of levelling a concrete slab that has settled and reinforcing its stability.  Using a calibrated injection of a high-strength polymer formula, the GeoFix method quickly and permanently corrects this problem. To do this, we drill small ⅝” holes in the slab or floor to be straightened, which we carefully seal once the operation is complete. No one will even notice we are there! GeoFix concrete lifting and straightening is the most economical solution. It also takes much less time than the traditional demolition and reconstruction method, allowing you to get back to business in a flash, usually within hours or days, depending on the scope of the work.

Why straighten a concrete slab without delay?

If you have noticed a settlement on part of your slab or on several concrete slabs, act quickly. Lifting your concrete slab and levelling it will prevent major problems, such as alteration and weakening of the structure of your building. It will also eliminate the risk of tripping and work-related accidents and limit equipment breakdowns.

What can cause a concrete slab to settle?

A poorly compacted base

Good preparation of the ground is necessary before pouring the concrete slab(s) to ensure good stability. If the base is poorly compacted at the outset, the soil may settle, causing the slab(s) to sag under the weight of the concrete, machinery and equipment. 


Freezing causes the ground to expand, so when the ground thaws, it may take on a different shape than before it froze. This can cause the slab to sag. In the summer, dry spells cause the clay soils to shrink, which affects the slab above. The same applies to very wet and rainy periods, which cause the clay to swell. 


Several factors can cause soil erosion, which weakens the base on which the slab rests. For example, damaged water and sewage pipes spill water into the soil, contributing to soil erosion. Nearby rivers, lakes and other bodies of water can also pose some erosion hazard.

The presence of heavy machinery and traffic 

Heavy machinery, in addition to its significant weight which can contribute to the compaction of the soil under the slab, creates vibrations which have the same effect and which can also displace the slabs. The same is true for car traffic.
