Preparing for your Concrete Tank
The first stage for the construction of a Panthers Concrete Tank is site preparation.
- Tanks must be constructed on natural level solid ground
- We recommend 50mm thick layer of gravel and 20mm aggregate at the base of the tank
- Site must be properly compacted and laser levelled foundation
- Tanks can be constructed above or below ground. Above ground requires concrete pump at additional cost. Tanks also out of the ground more then 800mm also require a concrete pump at additional cost.
- There must be sufficient access for trucks. Require 5 metre wide truck set up point near hole.
- Prior to excavation we recommend calling us if you require further information or site inspection.
- Once the concrete tank is constructed 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 1 metre clear around hole edge for construction
