During concreting, the usual practice is to use stones and concrete pieces to raise the steel bars. This is not at all recommended, as it will reduce the strength of concrete. Also, using stones with different shapes will cause uneven slanting to the concrete surface, which in turn would shift to one side to create voids. The solution? Kalliyath Cover Blocks with zero void design. Kalliyath Cover Blocks prevent chances of creating voids and thus increases the strength and durability of concrete surface.
It is the sophisticated design, created by experts, that strongly holds the steel bars, keeping them still at a point at the desired height, without slipping away.
Since Kalliyath Cover Blocks with Zero Void Design keep the steel bars strongly in their proper places, the full strength of the reinforced concrete can be achieved. The Cover Blocks can be used for concreting steel bars with 8 mm to 25 mm size range. If required, it can also accommodate steel bars with 20 mm to 50 mm sizes. Cover Blocks are made up of top quality materials which have proven compression strength and water absorption properties. As these cover blocks hold the steel bars efficiently, the concreting can be done at equal height and measures. This in turn, reduces material and cost, at the same time ensuring better strength and durability.
> Strengthens concrete
> Provides enough space between concrete and the steel bars
> Protects the steel bars from rust
> Eliminates the possibility of void formation inside the concrete
Building’s foundation footing, beams, pillars, roof slab, lofts, sunshade, etc.
The arrangements can be done as 20 mm for roof slab, 40 mm for pillars and beams, 20 mm for lintel and 50 mm for foundation. For added strength, arrange Kalliyath Cover Blocks at every 2 feet.
