Existing Stone & Pipe Septic System Repair

Septic systems have finite life spans (~38 years) and will need repair and maintenance. We specialize in repairing and expanding existing stone and pipe systems. We can also repair stone and pipe systems with InfiltratorĀ® systems when necessary.

Septic tanks, like septic systems, have a finite life span. We can replace old or deteriorating septic tanks with new septic tanks, even in tight workspaces. We have experience installing both plastic and concrete tanks.

Septic Tank Top Replacement & Repair

Oftentimes, the top of a septic tank will collapse or corrode before the sidewalls do. Gases trapped between the standing water in the tank and the tank top will erode away the top of the septic tank, occasionally causing the entire top to collapse. We can reinforce and reconstruct a new tank top over the existing top and extend the life of the tank.
