Repair of conventional reinforced concrete floors
About conventional reinforced concrete
Steel fibre-reinforced concrete is a composite material consisting of a concrete matrix with randomly distributed steel fibres. The steel fibres enable the concrete, which is relatively brittle, to accommodate tensile forces and resist a higher load, resulting in reduced crack formation.
Reinforced concrete has been used as a construction material since the beginning of the 20th century. Conventionally reinforced concrete contains steel bars or nets with a thickness of several millimetres as reinforcement.

Repair of conventional reinforced concrete floors – the ConcreteFloorSystems system:
Conventional reinforced concrete floors do not have foundations. Concrete floors without foundations can subside if the earth underneath them consolidates or if the floor is subjected to heavy loads. Generally, concrete floors suffer uneven subsidence. As a result the floor bends, fractures or cracks. At ConcreteFloorSystems we can always provide a solution to return the subsided concrete floor to the required level.
PREPARATION
PREPARATION
We start by drilling holes through the subsided concrete floor. The hole pattern depends on the underlying soil, the type of concrete floor, the client's requirements, and the required amount of relevelling.
EXECUTION
EXECUTION
We install tightly fitting injection plugs into the drilled holes. Next we use a special injection lance to inject the lightweight concrete lifting mix under the subsided concrete floor. The whole process is carefully monitored using laser surveying equipment.
HAND-OVER
HAND-OVER
Once the client has approved the work the injection plugs are removed and the injection holes are carefully filled. The concrete floor is ready for use after 24 hours.
