Light posts offer a unique outdoor design element. Incorporating a light post into your outdoor space is easy. Light posts can be built on existing patios, as well as on an unfinished surface such as soil. If you will be building in an area that does not have an existing patio or pavement, seeHow-to Sheet #220 Building Postsfor more information. To build on soil, you must create a foundation pad.
This project details how to build a light post that is 3 ft. tall on an unfinished surface.
Step 1: Begin the Foundation Pad Prepare a foundation pad by removing the grass and soil creating a hole 24 in. square by 4 in. deep. Poor soil conditions under the foundation pad may require additional attention (please visit Allan Block.com for more details). Step 2: Run the Conduit Carefully, stretch the conduit from the electrical source to the center of the foundation pad. (Figure 1). Allan Block recommends placing the wire in plastic conduit for protection. Always follow local electrical codes for correct conduit installation depth and wiring requirements.
Step 3: Install Wall Rock Place 4 in. of base rockin the foundation pad and methodically compact with a hand tapper, being careful to level in all directions.
Step 4: Create the Base Course To start the post base course, with the long sides facing out, set four corner blocks. With a dead blow hammer and a square, set and align the blocks.
Step 5: Build the Second Course Alternating the pattern to offset vertical seams, place the second course of blocks. Proceed with stacking additional courses, alternating the pattern until you reach your desired height. Next, making certain that the wiring extends past the post and post cap, add the final section of conduit and run the wiring to the top of the post.
Step 6: Cap the Post Finish the post with two post caps. Each cap will need a notch cut out of the center for the wiring. Wearing safety glasses, use a skill saw with a masonry blade, in the center of both Post Caps make a 2 in. wide notch, by making several 1 in. deep cuts to score the area. Then with a hammer and chisel, knock out the small pieces. Once the notch is completed, place both Post Caps on the post/pillar so that the notches line up.
Step 7: Secure the Caps Apply a bead of masonry adhesive (SRW) near the outside edge of each corner block. Place the caps on top of the post/pillar, making sure that your conduit extends up through the hole in the Post Caps.
Step 8: Place the Light Fixture Place the light base in the center of the post. Mark the position of the screw holes. For the masonry anchors, carefully drill holes using a drill with a masonry bit. Insert the anchors into the holes, add the light base and fasten to the Post Cap with screws. Then complete the wiring for your light using the factory instructions, and attach the light to the light base.
