Filler Roof Slab

The mechanism the filler slab is a mechanism to replace the concrete in the tension zone.

Filler roof slab.

The filler material thus is not a structural part of the slab. Once the shuttering is done the reinforcements are laid in grid form. The filler slab is based on the principle that for roofs which are simply supported the upper part of the slab is subjected to compressive forces and the lower part of the slab experience tensile forces. A filler slab is where we replace a portion of concrete in the tension zone of the slab with inexpensive lightweight filler materials such as clay roof mangalore tiles bricks earthen pots coconut shells glass bottles or any other creative material you can think of.

With proper supervision and workmanship leaks can be avoided. Leak proofing filler slabs. The chance of a leak in a filler slab is much the same as the conventional r c c slab. The filler material.

For example grid of 35cm x 50cm is used for magalore tile as filler material and grid of 45cm x 45cm is used for clay pots of 40cm diameter filler. The size of grid depends on structural design and size of filler material. By reducing the quantity and weight of material the roof become less expensive yet retains the strength of the conventional slab. Due to the use of low cost less heavy filler material such as clay pots rejected cali cut tiles and broken pieces of cement blocks the filler slab consumes less concrete and steel as compared to conventional rcc slab.

Since filler roof tiles are firmly bonded to and covered by concrete it does not collapse under the impact of say a coconut falling on the roof. Filler slab is based on the concrete portions and instead of placing filler material there and is one cost effective roofing system.
