What is Concrete Topping ?

Concrete topping is the process of overlaying (resurfacing) the hard, non-abrasive, structurally tough layer of concrete over any existing surface.

The old surface may be worn out or structurally not suitable for the special purpose; such as installing pieces of machinery and big equipment causing impacts and vibration at workshop, factories and garages, establishing bus stops and parking, for a smooth and raised level surface, or creating an impermeable surface layer.

Sometimes concrete topping is also done simultaneously after the construction of the base surface to provide a rigidly and cost-effective surface.

The concrete topping is generally classified as cost-effective and sustainable techniques of maintenance, rehabilitation and reconstruction. Their thickness may vary from 2 inches (50mm) to 10 inches (250mm).
