Epoxy Septic Tank LiningRestore Your Septic Tank Without Replacement
Epoxy lining is a cost-effective way to rehabilitate aging, leaking, or deteriorating septic tanks without the expense and disruption of complete tank replacement. A specially formulated structural epoxy coating is applied to the interior surfaces of the tank, creating a seamless, watertight barrier that restores strength and extends the life of the system.
Benefits of Epoxy LiningAvoid the Cost and Complexity of Tank Replacement
In many situations, replacing a septic tank can trigger permitting requirements, site disturbance, excavation, and environmental concerns. Epoxy lining often allows an existing tank to be rehabilitated without replacing the structure, making it an excellent option for:
Restore Structural Strength
The structural epoxy coating forms a durable protective shell inside the tank. Once cured, the lining becomes an integral part of the tank structure and helps prevent further deterioration from wastewater gases, moisture intrusion, and corrosion.
A properly applied epoxy lining can create a coating approximately 1/4-inch thick. This reinforced interior surface significantly increases the tank’s durability and resistance to future deterioration.
Stop Leaks and Infiltration
Cracks, seams, and deteriorated surfaces can allow groundwater to enter the tank or wastewater to escape. Epoxy lining creates a continuous, watertight barrier that seals leaks and helps protect both the septic system and the surrounding environment.
Extend the Life of Your Septic System
Epoxy lining can add decades of service life to an existing tank while avoiding the cost and inconvenience of full replacement.
The Epoxy Lining Process
Most septic tank lining projects can be completed in as little as one day.
Step 1: Pump and Clean the Tank
The tank is completely pumped of wastewater and solids. Remaining water and debris are removed to prepare the surfaces for rehabilitation.
Step 2: Pressure Wash
The interior walls and floor are thoroughly cleaned using high-pressure washing—up to 5,000 PSI—to remove buildup, contaminants, and deteriorated material.
Step 3: Vacuum and Surface Preparation
All loosened material, wash water, and debris are vacuumed from the tank, leaving a clean surface for repairs and coating.
Step 4: Repair Defects
Any cracks, holes, leaking joints, or damaged areas are repaired using specialized structural mortars designed for wastewater environments. They can even rebuild baffle walls separating the main compartment from the 2nd.
Step 5: Apply Structural Epoxy Coating
A thick structural epoxy lining is spray-applied to the tank interior, creating a seamless, corrosion-resistant, watertight barrier that bonds directly to the existing tank surfaces.
Step 6: Cure and Return to Service
After curing, the rehabilitated tank is ready to return to service with renewed structural integrity and long-term protection.

In many situations, replacing a septic tank can trigger permitting requirements, site disturbance, excavation, and environmental concerns. Epoxy lining often allows an existing tank to be rehabilitated without replacing the structure, making it an excellent option for:
- Properties located in archaeological or culturally sensitive areas
- High groundwater locations
- Waterfront and near-shore properties
- Wetlands and environmentally sensitive sites
- Areas with limited access for excavation equipment

Is Your Septic Tank a Good Candidate?
Epoxy lining may be an ideal solution if your tank is:
- Structurally sound but showing signs of age
- Leaking groundwater into the system
- Located in a difficult-to-excavate area
- Near a shoreline, wetland, or environmentally sensitive area
- In an archaeological review area
- Experiencing concrete deterioration or corrosion
