Sprayed Concrete

Contech has considerable experience in the application of dry and wet mix sprayed concrete for the repair and strengthening of damaged concrete structures. These techniques are also utilised for tunnel linings, retention of excavations and slope stabilisation.

 

The characteristics of traditional sprayed concrete can be greatly improved by the addition of polymer modifiers, silica fume, set accelerators, polypropylene and steel fibres.

 

We have a range of specialised gunite spraying equipment and trained machine operators and nozzle men to undertake a range of spraying projects.
