The use of Radcon Formula 7 by several companies on projects in Saudi Arabia and Kuwait has encouraged its supplier, Australian based Radcrete Pacific Pty Ltd, to begin marketing the product in the region.
Although Radcon 7 has been used in over 75 countries over the last 30 years, it is a new concept of waterproofing in the Middle East.
It contains unique technology, which waterproofs and protects reinforced concrete for the life of the structure, eliminating the need for future maintenance.
Unlike traditional membranes, which are applied to the existing concrete surface, Radcon 7 is a biochemically modified silicate, which is sprayed onto the surface, penetrating into the concrete to form a sub-surface membrane within the concrete matrix. It seals existing cracks up to 2mm and remains active in the concrete, re-sealing future cracks, should they occur, upon contact with water.
It is also different to crystal growth materials, which are designed for use only in areas of low thermal stress such as basements, because it is primarily used on ‘above grade’ high thermal stress projects such as bridges and exposed rooftops.
Radcrete Pacific managing director, Ed Byrne, claims Radcon 7 has many advantages over traditional membranes.
“It eliminates the need for protective screeds, is cost-effective and environmentally friendly,” he said.
“It is also easy to apply, is trafficable within a few hours of application and cannot be damaged by other contractors on site.”
He also said that Radcon 7 is particularly suitable in areas of high humidity because it enables concrete to out-gas moisture and therefore effectively eliminates any premature delaminating issues common with traditional membrane technologies.
Radcon 7 also provides excellent protection against chloride ion attack.
