Commercial Grease Tank Cleaning Service

Commercial grease tanks, interceptors, and FOG (fats, oils, grease) collection systems should be pumped and cleaned every 30 to 90 days depending on kitchen volume, local regulations, and tank size. However, full interior restoration with surface preparation and protective lining—like AmTech's DuraChem or HydraStone systems—is typically performed every 10 to 20 years or when inspections reveal structural corrosion, lining failure, or active leaks. Regular pumping removes accumulated grease, but only a protective lining prevents long-term corrosion from the aggressive acids and biological activity in FOG environments.

Grease tanks experience accelerated corrosion due to the breakdown of fats, oils, and grease into acidic byproducts, coupled with bacterial activity that produces hydrogen sulfide (H₂S) and other corrosive compounds. Steel tanks are especially vulnerable to pitting and permeation, while concrete tanks suffer from acid attack and rebar corrosion. Fluctuating water levels, high temperatures from connected dishwashers, and the presence of cleaning chemicals further accelerate deterioration. AmTech's chemical-resistant lining systems create a seamless barrier that isolates the substrate from these corrosive conditions, extending tank life by decades.

Yes. AmTech provides emergency repair services for actively leaking grease tanks, often avoiding the need for costly excavation and replacement. Our crews perform ultrasonic testing to map corrosion and identify leak points, then cut out and weld-repair perforated steel sections in accordance with API 653 standards. After structural repairs are complete, we apply a seamless DuraChem 500 series polylining or HydraStone cementitious lining that bonds monolithically to the substrate, creating a leak-proof barrier. This approach restores full containment integrity at a fraction of the cost of tank replacement and minimizes facility downtime.

DuraChem 500 series is AmTech's proprietary 100% solids poly lining system engineered specifically for harsh chemical environments including grease tanks, wastewater systems, and petroleum storage. It is spray-applied using plural-component equipment and cures instantly on contact, eliminating the multi-day cure times required by traditional epoxy or vinyl ester linings. The cured lining is seamless, resists acids, alkalis, hydrogen sulfide, and biological activity, produces zero VOCs during application, and bonds directly to steel, concrete, and fiberglass substrates. Facilities can often return tanks to service the same day or next day after application.

Yes. AmTech services all types of commercial grease management systems including indoor and outdoor grease interceptors, grease traps, FOG (fats, oils, grease) collection tanks, pump stations, and underground grease storage tanks. Our services include structural inspection, ultrasonic corrosion mapping, steel and fiberglass repairs, complete interior surface preparation via abrasive blasting or hydroblasting, and application of chemical-resistant lining systems. We work with restaurants, hotels, hospitals, universities, food processing plants, and any facility with commercial kitchen operations requiring compliant grease management infrastructure.

AmTech lines and repairs grease tanks constructed from steel, concrete, fiberglass (FRP), and fiberglass-reinforced plastic (FRP) laminates. This includes both above-ground and underground installations, single-wall and double-wall configurations, and tanks ranging from small under-sink grease traps to large outdoor collection systems. We also service associated structures like concrete vaults, manholes, and pump stations. Our material systems are selected based on the tank's substrate, stored contents, operating temperature, and site-specific conditions—ensuring optimal adhesion, chemical resistance, and long-term performance.

Project duration depends on tank size, substrate condition, required repairs, and lining system selection. A small grease interceptor with minimal corrosion might be cleaned, prepared, and lined in one to two days. Larger tanks requiring extensive steel repairs, multiple access points, or complex surface preparation may take three to seven days. AmTech's DuraChem instant-cure lining system dramatically reduces downtime compared to traditional multi-coat epoxies that require 24 to 48 hours of cure time between coats. Most facilities using DuraChem can return tanks to service the same day or within 24 hours after lining application.

Yes. AmTech's HydraStone Alkrete cementitious lining system is specifically engineered for potable water and food-contact applications, meeting NSF compliance standards. For grease storage and wastewater applications where food contact is not required, our DuraChem 500 series polylinings provide superior chemical resistance to acids, grease, and biological activity. All AmTech lining systems are applied by trained, OSHA 10 and OSHA 30 certified crews who follow strict safety protocols for work in confined spaces, ensuring compliance with OSHA regulations and maintaining the highest safety standards throughout the project.
