Preparation

Shotcrete and rock surfaces must be smooth and free of sharp edges. Generally, changes in direction and voids must be limited to less than 10% over any measured length. For example, over a 1m length, no void or protrusion should exceed 100mm. Fibre-reinforced shotcrete must be covered with a smoothing layer and generally aggregate sizes greater than 10mm should be avoided. Membrane must be placed over non-woven geotextile not less than 500g/m2 in weight.
