Polyurea is an extremely versatile material and one of its many uses is in the relining of process and storage tanks. One area where it is particularly useful is the lining of tanks and vessels which may be subjected to dynamic movement – such as sectional and bolted tanks. This is because the high elongation properties of the material (often in excess of 300%) mean that flexing and movement can be accommodated without cracking and splitting the tank lining.
This flexibility also makes polyurea particularly suitable for the lining and relining of concrete tanks which always have the potential for cracking due to the nature of their construction. This ensures that the contents of your storage tanks remain where they should.
Another significant advantage of using polyurea for lining tanks is that the cure time following application is significantly less than alternative epoxy and polyurethane materials commonly used. This means that your tanks can be returned to service much quicker following relining.
The high tensile strength of polyurea means that it effectively creates a ‘tank within tank’, allowing the refurbishment of tanks that could not conventionally be refurbished.
Polyurea comes in many formulations and from many manufacturers. Different formulations offer varying levels of elasticity, chemical resistance and gel time. There is no one material that can fulfil all tank lining requirements. We have been applying Polyurea tank linings since …… and can draw on our years of experience to select the correct manufacturer and material for your tank lining project. From WRAS approved polyurea tank linings for drinking water, to hydrocarbon resistant storage tank linings, we have the solution.
Many less experience contractors make the mistake of thinking the normal rules of coating application do not apply when using this fantastic material – much to their detriment. As with all of our tank relining projects, polyurea tank linings are subjected to the same stringent quality assurance – from preparation through to spark testing for pin holes.
