The EHBP-20 is intended for outdoor use, so it needs to withstand the worst weather mother natire wil throw it’s way.
There are several approaches to constructing a suitable foundation:
1. Pour a complete slab with steel rebar. Place locations for anchor screws.
2. Attach base to four 12″ sonotube piers.
3. Attach the base to a sturdy existing deck structure.
4. Attach to a sturdy concrete patio using drilled in anchors.
5. Set the four 8×8 wood roof support beams in ground. No concrete is required except for a small foot ant the bottom of the hole.
Fill the rest of the hole with tightly packed sand & gravel.
