One Piece Septic Tank Molds
One piece tanks meet requirements of those states that mandate the joint line of the tank to be above the inside liquid level of the tank and the water table outside of the tank. These septic tank molds are offered with our patented Hydra-Strip® system, air strip or hydraulic collapsing core. They feature spring-assisted hinged outer walls, rollback jackets or expanding corner shell. Septic tank molds are available in sizes ranging from 300 gallons to 10,000 gallons and can be set up for an inverted or upright pour. Add versatility to your mold set by incorporating cast-in-tees and compartment walls. Our baffle wall blockouts can convert multi-chamber molds into a single chamber mold. If you have a need for a single mold that can produce more than one capacity tank, we have standard and custom shims available to adjust tank volume.
