The slabs are made depressed in depth form the general floor level in wet area like toilets, balconies, wash area in kitchen etc. This is to ensure the wet and dry area separations in buildings. Even though the sunken slabs provided the toilet and balcony areas are found with a major quality problem of Dampness. This is due to the continues contact of water with building blocks. Here comes the importance of Kerb Construction.
Effect of dampness?
Dampness causes the wall suitable for the fungal attack. Also it results in the peeling off of wall plaster and the putty applied. Thus creates a major quality as well as aesthetic issue.
What is Kerb?
Kerbs are small PCC Belt provided over sunken slabs before starting the block work as per set out drawing. The Kerb can be constructed with at least a height of 20 cm and a width corresponding to Block or Brick coming over it as per the Drawing. It should be constructed and cured well before starting the Block work.
What kerbs do?
Kerbs prevent the blocks from absorbing water from the contact area and make the water proofing effective.
