To maximise the life of your tank you can prepare your site as follows:
- Uniform compaction (free from soft spots) and on level ground
- Tanks can be either placed on a 75-100mm bed of crusher dust (not sand), levelled, boxed and compacted, OR 100mm thick concrete pad
- All bases must be at least 200mm greater than the diameter of the tank
- Ensure that the base has some sort of retainment to prevent erosion, e.g. retaining beams
- A flexible coupling must be fitted to each outlet to validate the guarantee
- Specifications for slab for 46,825L (10,300 gal) and 36,369L (8,000 gal) tanks:
- The slab must be at least 200mm bigger than the base diameter of the tank
- The slab must be at least 150mm thick with 2 layers of F82 mesh 75mm apart and thickening of 200mm wide and 200mm deep with Y16 reo bar at the bottom of the thickening around the edge of the slab
