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. These 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.
