Drilling guideline for crack injection
Enter concrete slab thickness [D] to verify injection correctness
cm
Permissible drilling area as a % of slab thickness (??)
%
Distance (a) from hole entry point to crack

Drilling angle
[α]
°
Target number of holes per meter of crack:
Hole spacing:
Number of holes per side of crack:
Hole spacing:
Correct target calculations for given slab thickness
Drilling angle
Target depth at which hole intersects crack for given slab thickness b
Minimum drilling depth (b min)
Maximum drilling depth (b max)
Distance (a) from hole entry point to crack
The size of the limit of correctness
Height at which hole intersects crack for a given distance of hole entry point from crack (calculate b)
Does the drill intersect the crack within the slab?
