Measure and mark the locations for each light. Use a spacing of every 6 to 7 feet. Begin forcing the masonry chisel between the capstone and the stone below. . With the capstone removed, set your fixture where it will be placed and mark a line from the central point of the fixture straight back to the dirt. This is where you will score a line in the stone for the wire.
With your angle grinder, begin scoring the line you just marked. Make sure it’s deep enough so that the wire lays flat inside. If it’s not deep enough, the capstone won’t sit flush against the stone. Mark holes to secure the fixture with masonry anchors and screws. This is an optional step; you can actually even just glue the light in place and use the weight of the block to hold it down.
Use a small hammer drill with a masonry bit and in the holes you just marked, drill out about 1/2 to 3/4 of an inch deep for your masonry anchors. Place your anchor sleeves in the holes. If it’s a little bit tight, lightly press them in with the back end of a screwdriver or hammer. Set the fixture in the slot. Stick your screws in the anchors, then begin screwing them down. This will secure your fixture very tightly. Your hardscape fixture is now installed and ready for wiring.
Lighting up steps accentuates the beauty of this feature and provides a safe, visible pathway at night. A simple LED brick light can be integrated in the riser of each step, or another way is to insert a hardscape light under the cap of each step.
2. Railings & Posts
Deck posts can be illuminated with a variety of deck post lights (e.g., half-moon lights), available in cast aluminum and cast brass. Another option is to highlight deck railings using hardscape lights hidden under the lip of the railing.
3. Sitting Walls
A 12V hardscape light can be integrated into a brick or stone wall during construction. Hardscape lights are usually installed just underneath the top cap of a sitting wall or retaining wall, and are typically installed before the top cap is placed on the wall. You may need to ask the hardscape contractor to create a channel for your fixture wire run.
