US based Linex, which specialises in developing high performance protective coatings, has announced that its new spray-on Aquaurethane Extreme coating has been approved by the Secretary of State under Regulation 31 of the Water Supply (Water Quality) Regulations 2000 which is used to regulate potable, fresh and treated water storage reservoirs in Wales and England.
Although, traditionally, concrete pipes and tanks have been used to store water, the LINE-X Aquaurethane Extreme is the first spray on polyurea to be used in water storage tanks.
The LINE-X Aquaurethane Extreme consists of zero volatile organic compounds and is particularly designed to repair and protect the inside part of water storage tanks and pipes that have become vulnerable to leakages due to their porous nature. The spray-on is applied by specifically trained professionals who use high pressure multi component application equipment. The coating dries within five to seven seconds and the ease at which the coating can be applied makes it possible to cover a large area within a short span of time. Due to this factor pipes and reservoirs can be put back into service quickly. The spray-on coating creates a monolithic membrane, which prevents water from leaking into structural walls of the reservoirs and into the surroundings. The coating also has elastic properties, which allow it to contract and expand along with the concrete when it is used in pipes and prevent exterior contaminants from entering the treated and stored water.
