Shea Concrete, one of the largest precast concrete manufacturers in New England, has upgraded its residential septic tanks by adding rubber boots for inlet and outlet pipes. These boots create a more positive watertight seal between the tank and the pipes, which is essential if deflection or movement occurs during installation or settlement.

“The boots are physically bound into the septic tank structure,” explained Dave DeRose, production manager of Shea Concrete's Amesbury plant. “It’s a rubber sleeve that’s cast into the concrete. It creates a watertight seal between the rubber and the concrete.”

The rubber boots also give flexibility to the area connecting the tank and pipes so that it can be slightly maneuvered without causing damage. “The rubber will flex with the connection point, whereas it would not with the standard design most precast companies use,” DeRose said.

This flexibility is beneficial because it makes the tanks easier for contractors to install. “The standard septic design is more passive and can require a contractor to hydraulic cement the pipe connection to maintain watertightness,” said Greg Stratis, manager of Shea Concrete's Amesbury facility. “In addition, the hydraulic seal can crack and does not adhere well to the PVC pipe,” he said.

Dave Clark of D.F. Clark, Inc. in Ipswich, MA, a long-time Shea Concrete customer, said he regularly sees problems with the connection of pipe and concrete. “What we discovered is that we would cement all the pipes into the septic tanks, only to find that the bond between the hydraulic cement and the outside of the pipe and the tank would tend to break because of settlement or during the backfilling process.” He explained that as a result, rainwater would leak into the septic system, causing the leech field to fail well before its time.

Shea Concrete has now become an area leader by incorporating boots into all its residential tanks. “To see Shea Concrete take this initiative to install these boots on all their (residential) products, is a testament to their desire to promote products that are advantageous to our industry,” said Clark.

Stratis said that rubber boots can be added to any of Shea’s commercial septic tanks upon request. “In the future, we may provide this as standard on our commercial tanks,” he concluded.
