7. Walls filling, swimming pool and technical pump room fixing
Choose a non-compressible crushed stone (identical to that of the raft). Any other type of
backfill is strictly prohibited, and will result in non-compliance with this installation manual.
7.1 Workflow of the pool filling with rubble
1. To avoid rubble pressure and body deformation when filling with earth, it is necessary to install
3 supports along the width of the pool at intervals of aproximately at the loop outer side of the
curb, Fig. 15. Also fasten with straps by hooking them to the loops on the outer side of curb. Struts
remain in place until the basin is completely filled.

2. Once the pool is anchored, add 20 cm of water and once again check that the pool level is in
correct possition. Fill the pool 20cm of water to stabilize it.
3. Pour the rubble to the corners (see 7.2)
4. Start filling the water in to the pool, and pour the rubble at the same time. Normally the level of
crushed stone should not be lower than the water level. It is necessary to ensure that the pool walls
are free of any external or internal pressure and that the pool wall remains horizontal. (see 7.3)
5. When the pool is filled, one central strap must left which connects the two long sides of the pool,
and the anchors may be removed.
6. Build a concrete fence.
5. Once the concrete has solidified, the belt connecting the pool walls should be removed.
