Belt and braces approach for Aquawrap seal


Belt and braces approach for a watertight seal

Engineering firm Aquatech Solutions is making its Aquawrap watertight seal available on the local market. The butyl rubber sleeve provides a watertight seal around manhole, pipe or box culvert joints. It can also be used to prevent corrosion. It resists harsh soil conditions and provides a root barrier for any crack or joint.

Aquawrap adheres to all surfaces including concrete, earthenware, plastics (PVC, PE and PP) and is stable in ultraviolet light. It has an unlimited shelf life and design life of more than 50 years.

Aquatech Solutions director Leigh John says most of the councils and contractors he has spoken with so far are interested in using it as a “belt and braces” approach in a number of situations. These include in high water table areas, areas prone to ground movement, around larger-diameter manhole and pumpstation joints, and in connections between plastic pipes and concrete.
