Leak Sealing

Flat Patch
Tank Repair Kit

Manufactured by InduMar Systems, LP · Distributed by ECS

A carbon-epoxy composite repair system engineered for active sealing where localized repair is needed or full pipe wraps are impractical. A preformed carbon sheet combined with advanced adhesives enables working pressures up to 1,000 PSI (70 kg/cm²) and operating temperatures up to 350°F (177°C).

The Flat Patch Tank Repair Kit consists of a preformed carbon composite sheet and two advanced epoxy adhesives to provide superior leak sealing on flat surfaces. This novel approach enables the sealing of actively leaking defects, the localized repair of tank surfaces, and the ability to bond through oil contamination — recommended for pressure applications up to 1,000 psi with a built-in 4:1 safety margin. Return to service at pressure may be accomplished in ~2 hours for temperatures above 75°F.

Key Attributes

Adaptable composite construction with time-efficient installation addresses a wide range of tank sizes
Advanced adhesives eliminate leaks without the need to drain the tank
Cartridge dispensing minimizes waste, ensures complete mixing, and manages pot life
Short cure time allows rapid repair and reduced time on site
Outstanding compressive, flexural, and adhesive bond strength
Accelerated cure times possible with annealing of the installed repair
Restores operations up to 1,000 psi and provides localized corrosion inhibition
