Site Preparation Delivered to Site

The first stage for the installation of a Panthers Concrete Tank is site preparation.

• Tanks must be installed on natural level solid ground
• If there is a concrete slab underneath, before sitting the tank on the slab, you will be required to put a couple of bags of
  wet self levelling grout to ensure tank is fully supported on slab as some slabs are not screeded level
• We recommend 50mm thick layer of gravel at the base of the tank
• Site must be properly compacted and laser levelled foundation
• Tanks can be installed above or below ground.
• There must be sufficient access for trucks. Refer to site preparation specific to the tank size
• Prior to excavation we recommend calling us if you require further information.
• Once the concrete tank is installed you must take care when backfilling around the tank to keeps its structural stability.
• Overflow pipe to be diverted away from tank base
• Tanks fully in the ground must never be empty. Once the tank is completed, fill the tank with a minimum of 25%.
• Empty tanks are buoyant. Do not let water on the outside of the tank in the excavated hole build up as the tank will float.
• Do not put excavated soil on hole edge. Keep 500mm clear around hole edge for construction
