BACKFILLING AND PLACEMENT OF TANK

Filling with water in stages - min. 30cm

Backfilling the body of the tank requires the use of appropriate backfill material (the same as was used for making the bedding) and

the proper execution of backfilling.

The backfill material has to be consolidated and compressed carefully and in layers (up to 30 cm in height) to 97% Proctor compaction

over a minimum width of 50cm from the wall of the tank. Simultaneously with backfilling the body of the tank, water must be poured

into the tank itself, so that the level of the backfill material equals the water level in the container. When backfilling, pay special

attention to the space on the bottom. Using manual aids, fill in and consolidate the entire empty space, thus preventing potential

subsequent deformation of the bottom.

When backfilling the PE container, make sure that heavy construction machinery does not drive over the body or in the area of

backfilling.
