- The ideal plug spacing is 300-500mm apart, therefore you require 2-3 plugs per meter of wall (per side).
- The suggested height is 300mm from the floor (or can be placed at height where damp is most prominent).
- You require a Rotary Hammer drill & 40mm SDS Max Masonry drill bit (recommended). The 40mm SDS core bit will also work.
- This can be hired from most tool hire shops.
- If possible, you should drill straight through the wall, and insert the plugs on either side (for maximum efficiency).
- For cavity walls - drill into the center cavity of the wall between the front and back layers of bricks (approx. 140mm)
