Due to the reduction of concrete volume the overall cost of slab is lower than solid slab even after considering additional cost of mangalore tiles.
Filler slab roof.
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.
Thus the filler slab as the roof has the following advantages.
Filler slab technology is a simple and a very innovative technology for a slab construction.
The filler material thus is not a structural part of the slab.
The mechanism the filler slab is a mechanism to replace the concrete in the tension zone.
The filler material.
Leak proofing filler slabs.
Strength of filler slabs tests by different institutions and laboratories has proved the load bearing capacity of filler slab and found it no less in performance from the conventional r c c.
Filler slab is based on the concrete portions and instead of placing filler material there and is one cost effective roofing system.
Since filler roof tiles are firmly bonded to and covered by concrete.
Filler slab roof construction.
With proper supervision and workmanship leaks can.
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.
Once the shuttering is done the reinforcements are laid in grid form.
