the border should be fixed to prevent the blocks from
shifting and getting loosened
Bedding Materials : the bedding materials consists
of pure sand duly compacted with a surface vibrator(Compactor).
This layer should be not less than 2" to provide
sufficient cushion to the blocks.
Layering of Blocks : The blocks can be directly
palced on this bedding layer prepared. The blocks should
be placed very close to each other to avoid any shifting.
This special care has to be taken because the joints
are not filled with cement.
Compaction : The surface compactor is again plied
on the blocks laid with a little sand rolled over it.
This process helps the sand to fill any voids or air
blocks in the joints if the blocks are laid. This process
also helps to level any uneven laying of blocks.
e) Cleaning : The floor laid
now needs proper cleaning of unused sand on it and is
ready for use.
