Our teams’ experience and capabilities range from simple surface beds to drainage pumps and waterproof walls or seals. With the introduction of a professional engineer into Mantella we are now able to design and certify all types of civil structures.

We have developed techniques to place and transport 35MPa ready-mixed concrete up to 140m underground over several hundred meters with pumps or kilometres in flameproof concrete mixer machines. We also have a purpose built shuttering system used in building waterproof concrete walls.

The sealing agent is a two component polypropylene based expanding flexible material. Water leaks of hundreds of litres per minute across a gap of 80mm have been successfully stopped.
