The varied climatic conditions and the penetration of de-icing salts are the main causes of the deterioration of multi-storey concrete parking lots. These include cracks caused by freeze-thaw, premature shrinkage of concrete, scaling caused by melting salts, carbonation and many other signs of degradation. When these appear, it is essential to communicate quickly with our professionals in order to ensure the safety of your users and to protect your investments in the long term.
Here are the different types of work that can be done in an indoor parking lot:
Repair the concrete on the upper surface (above) and lower surface (below) of the slabs;
The slabs form the floors of a multi-storey parking lot. Since they form the fundamental basis of this structure, it is imperative to repair them as soon as the first signs of deterioration appear. These can be present above and / or below the slabs and our team of professionals will be able to make the necessary repairs to ensure the protection of users.
Repair columns and beams;
Replace the reinforcing steel;
Cimentiers MC are often called upon to replace reinforcing steel during underground parking repairs. In the form of rods or wire mesh, this material is necessary for the reinforcement of the concrete mixer structure. Reinforcing steel is primarily intended for formwork tasks as well as for repairing columns, beams, slabs, etc.
Perform formwork work;
Formwork is often mandatory when repairing underground parking lots. This temporary structure, which is the formwork, will notably allow the construction of work with defined shapes. Usually, this type of work is done in areas where there are signs of serious delamination in the slab, beams and columns.
Inject cracks with epoxy and / or polyurethane;
Cracks caused by freeze / thaw, shrinkage of concrete, movement or any other factor can be repaired by the injection of products such as epoxy and polyurethane. The application of these materials prevents water, de-icing salts and excessive moisture from penetrating the concrete and potentially attacking the rebar.
Repair the expansion joints;
Replace structural slab drains;
Cimentiers MC sometimes have to replace structural slab drains when performing repair work in indoor parking lots. To do this, the company's specialists crush the cement on the periphery of the damaged drains, change the drains and again pour concrete around them.
Replace the waterproofing membrane;
The waterproofing membrane prevents the penetration of water, moisture and salt which directly affect the reinforcing steel. Its replacement is therefore important to prevent structural damage and avoid expensive repair costs. A rigorous visual inspection is suggested every year in order to detect anomalies and cracks that could cause more extensive repairs.
