What is a manta floor?

A Manta floor is also called a ribbed cassette floor. The ribs, or concrete beams, of these floors are located on the underside. Two ribs are attached to each element, with a thin floor slab between them on the top. This slab is 55 millimeters thick. The element width is 1,200 millimeters.

In the Netherlands, a large number of homes have manta flooring. A manta floor of moderate to poor quality poses significant risks that you'd rather avoid. Therefore, always have a building inspection carried out, during which the floor is thoroughly examined.

The biggest risk of the manta floor

Calcium chloride is often used in the production of the elements for Manta floors to accelerate the drying process. The floor's reinforcement rusts away due to the presence of calcium chloride. This prevents it from adequately absorbing tensile forces, eventually causing the reinforcement to expand and crush the surrounding concrete. This is known as concrete rot.

The greatest risk is that the manta floor will fail because the ribs simply lose their load-bearing capacity. Moreover, the reinforcement can also be damaged by insufficient compaction of the concrete or by being too close to the surface. Therefore, the presence of calcium chloride is not necessarily the cause of concrete rot.
