When carrying out major repairs to long-existing housing with concrete floors, it is very often necessary to restore the integrity of these seemingly “indestructible” coatings. Unfortunately, they are also subject to aging and gradual destruction.
Over a long period of its service, the screed, once poured over the floor slab, can become covered with a network of cracks and begin to crumble under the influence of deforming forces (associated, for example, with building shrinkage, seismic points, operational static and dynamic loads). Concrete can lose its strength over time, especially if used in unfavorable conditions where opportunities for erosion to activate arise.
Bringing dilapidated concrete floors into a “working” condition can be done in different ways, depending on the extent and nature of the damage. And it should be noted right away that this is not such a simple task as it may seem at first glance. There are even situations when it is much easier to completely dismantle the old screed and pour a new one, rather than trying to restore it.
