THE GRAF SEPTIC TANK REVIEW
Welcome to the Graf septic tank, one of the best septic tanks in the world. Why do we say that? Well for starters Graf has been in the business for 50 years. They are made from light durable plastic, and their build quality is one of thein the world. There deisgn means that the tank can be installed it can be installed without a concrete base or blanket surround in dry conditons. What is more, these tanks are also approved by UK building regs, The Environment Agency, British Water and Sepa.
Because of its uniques design the Graf septic tank does not need concreting just granular backfill. Simply dig the hole. Place the tank onto the base of the hole, and backfill around the tank with sand or 20-30mm shingle. The granular backfill absorbs any water pressure that builds up in the soil around the tank, and this is why it does not need concreting. Very clever indeed!
