Concrete – one of the most versatile products ever created and utilised heavily as both a primary floor surface and also as the main substrate for the application of flooring compounds.
In both cases, the quality of the finished surface is directly related to the quality of the concrete preparation techniques used. In the case of newly laid concrete, a mechanically weak surface layer with high water content forms during the drying out period (known as laitance) which must be removed prior to polishing the concrete or applying a surface coating. For existing concrete, any failed coating or contaminants (e.g. greases, oils, and other solids) should also be removed prior to the application of a new coating.
Roads, bridges & walkways are also places where concrete is found as a primary surface. Rough, uneven surfaces can be dangerous, leading to trips & falls. Concrete preparation techniques can also be applied here to provide a smooth, safe environment to pedestrians.
