TekSeal™

TekSeal is a low density cement foam that can be used for general void filling and the construction of lightweight barriers, bulkheads and stoppings. Typical applications include void filling above closed-off arches in tunnel drives or after rockfalls and lightweight barriers for ventilation control.

It is supplied in 25 kg lined woven polypropylene bags and forms cement foam on mixing with water in a purpose designed placer.
