Application :
- With Al-Safwa Helasto-Ring, the pavement does not touch the waterproofing blanket, but is separated from it by a hollow space; in this way, the pavement can expand and contract without damaging the water-tight blanket.
- The slabs are only resting in place, and in case of repairs to the waterproofing blanket, it is not necessary to damage the floor; it is sufficient to raise a few of the square slabs to carry out the maintenance.
- Puddles can no longer form since rainwater runs directly to the drains between the open joints and the square slabs.
- Different sizes and Products can be manufactured .
