Damaged reservoirs enveloped
ENVELON polymerics is capable of sealing water reservoirs and other structures prone to leakage or water incursion, thus providing an upgrade option for industrial water facilities and main town supplies.
Because time is an important factor in dealing with damage to water storage and similar equipment, Envelon claims to be suitable because it is retro applied.
Manufactured by Australian company Dominion Plastic Industries , use of the “liquid envelope” means structures that previously would have been condemned are given a renewal and a new lease of life.
Euan Sutherland, managing director of Dominion Plastics, believes water tanks represent the far reaching ability of these polymerics to provide inexpensive repairs.
“To knock down a water reservoir and replace it is a very costly exercise, particularly in regional areas where councils not only have limited funding they also have a significant reliance on such equipment,” says Sutherland.
“Envelon allows authorities to thoroughly clean the reservoir inside and out, and then ensures it is sealed against any form of leaking. Effectively, it reduces the prospects for concrete cancer and other physical degradation and extends the life of the tank infinitely,” he adds.
The liquid is applied with a spray gun and is said to leave no seams, butts or leaks; it needs no protective overcoat and is touch dry in 30 minutes.
Protection is provided in two ways: firstly, the coatings form flexible films with low water vapour transmission rates while stopping substrate corrosion caused by electrolytic action or the presence of water-borne oxygen. Its thick film also protects against surface damage from abrasion and chemicals.
The strength it provides is a barrier against bending, hammering, scratching or stretching. Whether the application is above ground or below ground, the coating will remain waterproof.
The continuous all-over skin can envelope a structure or object to seal out moisture. It caulks around openings, fills and covers cracks, and does not weather away or flake as the films are flexible and elastic in a temperature range from sub zero to tropical temperatures and expand and contract with the underlying surface to which they are applied.
These polymerics are stabilised to retain colour, gloss and flexibility even in prolonged exposure to sunlight and harsh environments.
Exhibiting qualities that protect against corrosive fumes, these products suit structural work, ducts, the underside of roof areas and the walls and equipment in plating, pickling and electrolytic cell rooms and in chemical plants.
