PRODUCT DELIVERY AND INSTALLATION DETAILS:

EXCAVATION:
Excavation length and width should be at 450-600mm (18"-24") larger than the dimensions of the concrete tank. More clearance may be required if work is to be completed on the outside of the tank. Excavated material piles should be located at a distance away from the excavation in order to allow access for the delivery vehicle.

BEDDING:
A bedding is required in order to minimize stress on the tank structure. A bedding should consist of 150mm (6" to 8") of clean 20mm or less (3/4" or smaller) crushed stone or sand. The crushed stone must be level with all large stones removed. The soil conditions need to be stable enough to support the weight of the tank and its contents when full.

DELIVERY:
Delivery is made with a crane equiped truck. Tanks can be placed in position if the site is accessible. Firm flat ground is required as well as 18 ft of overhead clearance. NOTE: Crane operators can refuse to attempt an installation that is not safe or that could damage equipment and/or property.

CONCRETE/MASTIC JOINT SEALS:
The mastic sealant is to be placed on the lower joint surface once the lower portion of the tank has been placed into the excavation. All joint surfaces must be clean and dry before placing the mastic sealant. Once the upper portion of the tank has been set in place it will take some time before the sealant has settled in the joint. The time required will vary depending on the temperature. Usually 12 - 24 hours. Avoid backfilling before the tank has settled in the joint.

BACKFILLING:
When backfilling the excavation care must be taken to ensure that no stones or rocks are placed against the tank. The machinery used to backfill must not place its weight over the edges of the excavation or on the tank itself.
Tanks can float if the fluid level in the excavation rises too high. Excavated material can be placed on the top of the tank in order to weigh it down. NOTE: Filling the tank with water is not recommended unless the outer walls are being supported with fill. The water can place too much stress on an unsupported wall.

NOTE:
WE (REIDS PRECAST CEMENT PRODUCTS LTD) CANNOT BE HELD RESPONSIBLE FOR DAMAGE TO TANKS THAT HAVE NOT BEEN INSTALLED ACCORDING TO THE RECOMMENDED INSTALLATION INSTRUCTIONS.
