1. Use water when drilling asphalt or concrete.

Remove the asphalt block from the drill bit.

2. Do not use water when drilling gravel.

Drill approx. 50 ... 100 mm (2 ... 4 in) at a time. Clean the drill bit in between to avoid gravel from sticking inside.

3. Verify the correct depth with the dummy block. If the hole is too deep, add filler sand.

If there is water in the hole, use a cloth to dry it.
