Water Tank Leak Detection & Repair Services

While plumbers can address basic piping connections and fixture issues, structural water tank leaks—especially those involving corrosion, permeations, or lining failures—require specialized tank repair expertise. AmTech's engineer-trained crews perform ultrasonic leak detection to identify invisible permeations, execute API 653-compliant structural steel repairs, and apply proprietary HydraStone or DuraChem lining systems that create permanent, monolithic barriers. These solutions go far beyond standard plumbing repairs and are designed to restore full tank integrity for decades of continued service.

AmTech uses ultrasonic testing (UT) equipment to scan tank walls and bottoms, detecting minute permeations, pinholes, and areas of wall thinning that are invisible during visual inspection. This non-destructive testing method produces detailed thickness maps showing exactly where corrosion has compromised the tank structure. For active leaks, visual inspection combined with pressure testing and moisture mapping identifies the leak source. Ultrasonic detection is critical for regulatory compliance, preventive maintenance, and determining whether repair or replacement is the most cost-effective solution.

Water tank leaks result from several factors: internal corrosion caused by aggressive water chemistry (low pH, high chloride content, or softened water), external corrosion from ground contact or condensation, mechanical damage from overpressure or impact, weld seam failures due to thermal cycling or poor original construction, and deterioration of existing lining systems that exposes bare substrate to water. Tanks storing hot water are particularly susceptible to accelerated corrosion. Regular ultrasonic inspection and preventive re-lining with systems like HydraStone Alkrete significantly reduce leak risk and extend tank service life.

Emergency leak repairs with temporary containment can often be completed within 24-48 hours to restore basic operations. Comprehensive repairs involving structural steel work, surface preparation, and lining installation typically require 3-7 days depending on tank size, damage extent, and the lining system used. AmTech's DuraChem instant-cure polylining drastically reduces downtime compared to traditional multi-coat epoxy systems that require days of cure time between coats—tanks can often return to service within 24-48 hours after DuraChem application. Hot water tank repairs using HydraStone Alkrete require longer cure times but provide superior high-temperature performance.

Yes, in most cases. AmTech specializes in restoring structurally compromised tanks through a combination of ultrasonic assessment, surgical steel repairs (cutting out corroded sections and welding in new steel), and application of seamless lining systems that eliminate future corrosion pathways. This approach saves tens of thousands of dollars compared to full tank replacement and avoids the extensive facility disruption associated with tank removal and installation. Replacement is only necessary when corrosion is too extensive or when the tank no longer meets current code requirements for its service application.

For potable water and hot water tanks, AmTech uses HydraStone Alkrete—a proprietary cementitious lining that is NSF-certified for potable water contact and can withstand temperatures up to 900°F, making it ideal for domestic hot water, boiler feed, and thermal storage tanks. For cold water, chemical, and wastewater applications, DuraChem 500 series instant-cure polylining provides superior chemical resistance, zero VOC emissions, and eliminates extended cure times. Both systems bond monolithically to steel, concrete, and fiberglass substrates, creating seamless barriers with no joints or seams where future leaks could develop.

Yes. AmTech provides 24/7 emergency response for active water tank leaks, catastrophic corrosion failures, lining blowouts, and regulatory shutdown scenarios. Our engineer-led field crews mobilize rapidly across the US and Canada with proprietary repair materials including instant-cure DuraChem polylining, HydraStone cement systems, fiberglass laminate kits, structural welding equipment, and PLS 755 Tank Tape for temporary leak containment. Emergency services include rapid damage assessment, temporary leak mitigation to prevent facility flooding, permanent structural and lining repairs, and verification testing before the tank returns to service.

Water tank leak repair costs vary significantly based on tank size, damage extent, accessibility, and the required repair scope. Minor pinhole repairs with localized patching and spot-lining may cost a few thousand dollars, while comprehensive repairs involving structural steel replacement, full interior re-lining, and manway retrofitting can range from $10,000 to $50,000+ for large commercial or industrial tanks. However, these repair costs are typically 50-70% less than full tank replacement, which includes excavation, disposal, new tank procurement, installation, and extended facility downtime.
