Drilling
Basic operation: Drilling
As in the case of conventional operations, if the drill hole has not been made according to instructions, the demolition will fail.
- Drill hole diameter: 30 to 65 mm. At temperatures of over 25º, the maximum diameter must be 50 mm. Up to diameter 40/45, CRAS VERDE or Universal should be used; for larger diameters, CRAS AZUL o AZUL ESPECIAL should be used.
- Distance between holes: = drill bit diameter x 10
- Depth: Always larger than the distance between holes, minimum 50 cm.
The above references will serve as guidelines, but, in all cases, we recommend you to make a preliminary test with few holes.
