SUBSTRATE QUALITY

In-situ concrete:
Clean, sound and dry, homogeneous, free from oil and grease, dust and loose or friable particles.
Shotcrete:
If the substrate is rough, a fine gunite layer on the substrate with a min. thickness of 50 mm and cleaned without loosen aggregates, stones, nails wires, etc..
If steel existed, such as girders, reinforcement mesh,anchor, etc., a min. 50 mm gunite layer is a must as a cover.
Substrate should be smooth and solid.
