The 300mm Adjustable riser is designed for the underground range of tanks.
This riser is designed to be used when the underground tank is going to be put under a driveway or pathway. Simply cut the riser to length and the steel galvanised plate can then be finished flush with the height of the concrete.
The riser can also be used where the finished height of the ground or landscaping is unknown at the time of install. Once landscaping is complete, adjust the riser to match the ground level.
Contact Poly Water Tanks to order a larger riser up to 600mm.
