Septic Tank Structural Repair
Professional structural repair services that restore your septic tank’s integrity and extend its working life
5 Highlights on Septic Tank Structural Repair
- Crack and fracture sealing — We locate and repair cracked concrete, fiberglass, and polyethylene septic tanks using commercial grade epoxy liners and crack sealant to restore a watertight seal before groundwater infiltration worsens the damage.
- Baffle replacement and reinforcement — Deteriorated or collapsed inlet and outlet baffles get replaced with corrosion resistant tee fittings, keeping solids, scum, and effluent properly separated inside the tank.
- Riser and lid restoration — Compromised access ports, risers, and lids are patched, resealed, or replaced so your system stays sealed, safe, and accessible for future pumping and inspection.
- Wall and floor relining — We coat and reline interior tank surfaces with structural membranes and fiberglass repair kits that reinforce weakened walls and stop active leaking at the source.
- Root intrusion remediation — Invasive roots that have fractured tank walls or penetrated joints are removed, and the affected areas are grouted, patched, and waterproofed to prevent reentry.
Why Choose Our Septic Tank Structural Repair
Septic tank structural repair is a specialized trade. Not every septic company has the equipment, training, or materials to diagnose and fix compromised underground tanks. Lakes Region Septic does.
Our technicians carry years of hands on experience repairing precast concrete tanks, fiberglass units, and polyethylene holding tanks across residential and commercial properties. We use inspection cameras to diagnose the exact location and severity of every crack, fracture, or corroded section before we begin work. That means no guesswork and no unnecessary excavation.
We stand behind every structural repair with a written workmanship guarantee. Our crews seal, patch, reline, and reinforce tanks to meet or exceed local code requirements, and we document every step for your records and for health department compliance.
Lakes Region Septic owns its own vacuum trucks and excavation equipment. We don’t subcontract the critical work. When you call us, our team shows up, diagnoses the problem, and completes the repair — start to finish.
We’re a top rated, trusted septic service provider in the Lakes Region. Our pricing is transparent, our timelines are honest, and our repairs last. If your tank has structural damage, we’re the qualified experts to fix it right.
Signs You Need Septic Tank Structural Repair
Septic tank structural repair becomes necessary when the physical body of your tank starts to fail. Here are five signs that your tank has a structural problem demanding professional attention.
Standing water or soggy soil near the tank. When a septic tank wall cracks or a joint seal fails, wastewater seeps into the surrounding soil. You’ll notice wet, spongy ground directly above or beside the tank even during dry weather. This seepage can contaminate groundwater and violate health codes.
Foul odors near the tank or inside the home. A fractured lid, a corroded riser, or a collapsed baffle lets sewer gas escape. If you smell sewage near your access port or in your basement, the tank’s structural envelope is compromised. Gases like hydrogen sulfide shouldn’t reach the surface on an intact system.
Repeated backups after recent pumping. Your pumper truck just emptied the tank, but drains are slow again within weeks. Groundwater infiltration through cracked walls can refill a damaged tank rapidly, overwhelming the system and pushing effluent back toward the house.
Visible cracks or shifting during inspection. A camera inspection or visual check through the access port reveals hairline fractures, spalling concrete, or sections of wall that have shifted out of alignment. These are signs of active deterioration that will worsen with freeze and thaw cycles and soil pressure.
Tank alarm or float switch triggering frequently. If your pump chamber alarm keeps sounding, the problem may not be the pump. A structurally failing tank that allows infiltration raises liquid levels beyond what the float switch considers normal, triggering repeated false alarms.
Our Septic Tank Structural Repair Process
Septic tank structural repair at Lakes Region Septic follows a clear, methodical sequence designed to identify the damage accurately and fix it permanently.
Step 1 — Locate and expose the tank. We use property records and electronic locators to find the tank. Our crew excavates the soil above the access ports, risers, and lid to expose the full working surface.
Step 2 — Pump and dewater. Our vacuum truck pumps out all sewage, sludge, and effluent. We dewater the tank completely so every interior surface is visible and workable.
Step 3 — Inspect and diagnose. A technician enters or deploys an inspection camera to examine walls, floors, baffles, inlet and outlet connections, and joints. We document every crack, corroded area, fracture, and point of infiltration.
Step 4 — Repair and reinforce. Depending on the damage, we seal cracks with structural epoxy, patch spalled concrete with mortar, reline interior surfaces with fiberglass or protective coatings, replace collapsed baffles, and waterproof compromised joints. Rebar reinforcement is added where walls have weakened.
Step 5 — Test and backfill. We fill the tank with water to confirm a watertight seal. Once the repair passes our leak test, we backfill the excavation, compact the soil, and restore the grade around the tank.

FAQs About Septic Tank Structural Repair
What is septic tank structural repair?
Septic tank structural repair is the process of fixing physical damage to the tank body itself — cracks in walls or floors, corroded surfaces, fractured joints, collapsed baffles, and compromised lids or risers. The goal is to restore the tank to a watertight, structurally sound condition so it contains wastewater properly and meets code.
When should I get my septic tank inspected for structural damage?
You should schedule an inspection every three to five years during routine pumping. If you notice soggy ground near the tank, persistent sewage odors, frequent backups, or your alarm keeps triggering, call for an inspection right away. Catching a crack or corroded wall early prevents a full tank failure.
How long does a structural repair take?
Most septic tank structural repairs take one to two days. Simple crack sealing or baffle replacement can wrap up in a single visit. Extensive relining, wall reinforcement, or waterproofing may require a second day for curing and leak testing.
Can a cracked septic tank be repaired, or does it need replacement?
Many cracked tanks can be repaired successfully. Hairline fractures, localized spalling, joint separations, and single wall cracks respond well to epoxy injection, patching, and relining. If the tank has multiple collapsed sections, severe structural compromise, or has shifted in the ground, replacement becomes the better option. Our technicians will diagnose the damage and give you an honest recommendation.
Does septic tank structural repair require a permit?
In most Lakes Region municipalities, structural repairs that don’t change the tank size or system layout don’t require a full permit. Some towns do require notification or inspection by the local health officer. We handle the paperwork and coordinate with your local authority so you stay compliant.
How much does professional septic tank structural repair cost?
Costs depend on the type and extent of damage, tank material, depth of excavation, and materials needed. Minor crack sealing may run a few hundred dollars. Full relining or baffle replacement with excavation typically ranges higher. We provide a detailed written estimate before any work begins.
