Bolted Steel Tank Lining for Wastewater

AmTech commonly uses the DuraChem® 500 series for wastewater tank lining. It is a 100% solids poly lining system that bonds directly to prepared steel and cures instantly on contact. The finished barrier is seamless and monolithic, helping protect bolted steel tanks from hydrogen sulfide, fluctuating pH, biological activity, corrosion, and abrasive suspended solids.

Wastewater tanks are exposed to aggressive service conditions, including hydrogen sulfide gas, acids formed by biological activity, changing pH levels, suspended solids, and cleaning chemicals. A chemical-resistant lining helps isolate the steel from these corrosive forces, reducing pitting, coating failure, leaks, contamination risks, and premature tank replacement.

Yes. Bolted tanks require careful detailing around seams, joints, penetrations, nozzles, and uneven transitions. AmTech can use preparation methods and compatible detailing materials such as PLS 755 Tank Tape to bridge gaps and create a smoother surface before lining. This helps reduce voids, weak points, and premature failures around difficult geometry.

Surface preparation typically includes cleaning, removal of old coatings, rust, oxides, contaminants, and scale through abrasive blasting, wet blasting, hydroblasting, or mechanical profiling. AmTech verifies surface profile, ambient conditions, dew point, and humidity before lining. Proper preparation is essential because chemical-resistant linings rely on strong adhesion to the substrate.

Project duration depends on tank size, access, corrosion severity, repairs, and required containment, but the DuraChem® 500 system can reduce downtime because it cures instantly during application. Unlike traditional multi-coat systems that may require long cure intervals, many tanks can move toward inspection and return-to-service steps much faster after application.

Yes. AmTech crews can address corroded steel, pitting, damaged nozzles, failed coatings, and structural concerns before lining begins. Repairs may include cleaning, steel patching, welding, rebuilding attachment areas, and surface profiling. Correcting substrate issues first helps ensure the new lining performs as a long-term corrosion barrier.

Yes. DuraChem® 500 series linings are used in municipal wastewater treatment plants, industrial process wastewater facilities, lift stations, clarifiers, digesters, equalization tanks, and commercial wastewater applications. The system is designed for aggressive wastewater environments and can bond to properly prepared steel or concrete substrates.

Yes. AmTech provides emergency tank repair for active leaks, sudden corrosion breakthroughs, lining delamination, nozzle blowouts, structural damage, and regulatory shutdown situations. Engineer-led crews can mobilize with repair materials, temporary sealing options, welding equipment, and lining systems to help restore tank integrity while minimizing facility downtime.
