Waste Water Treatment Plants

Mountain Grout Strong

Wherever there is concrete and water, there are cracks and leaks. Mountain Grout has been used to seal many leaking concrete tanks. Water treatment facilities are one of the primary beneficiaries of the performance of Mountain Grout. Mountain Grout Polyurethane Resins are injected into leaking wastewater treatment tanks to seal cracks and stop the leaks, saving thousands of gallons of water and thousands of dollars in infrastructure repairs over time.

Injecting Water Tanks with Polyurethane Resin

Installers grout vertically starting at the bottom of each crack and the foam follows the crack upward, sealing it as the foam cures. The foam fills the void and keeps the water where it is supposed to be – inside the treatment tank. Mountain Grout can also be used on oil tanks and potable water tanks. If it is a potable water tank, Mountain Grout Flexible is UL Classified for use on NSF-61 jobs.
