Septic Tank Renovation

A 5000 gallon brick septic tank had high levels of water infiltration filling the tank every 48 hours with ground water, resulting in high emptying costs and to the local environment.


Provide a watertight barrier that would last 10+ years to a septic tank that required renovation.


The septic tank was jetted then wet abrasive blasted to remove all weak substrate allowing us to achieve full adhesion with Ultracoat protective coating.

Areas of high infiltration were injected with our water stop injection system to stop groundwater from entering the tank during coating works.

Tank was then sprayed with an acid etch and followed by a anti-microbial wash to kill any bacteria that may affect the bond between the Ultracoat and the substrate.

The tank was then coated with 6mm of Ultracoat pure epoxy coating system. The tank was only out of service for three days from start to finish.

Another successful project undertaken by Ultimate Coatings Limited. The UK leader in tank, bund and sump lining and in sprayed foam and polyurea solutions.
