Floor Leveling and Preparation.
Plan to assemble a floating wall mount pergola against a wall where you can excavate and create a level platform, at least, the
overall outer dimensions of the pergola. If soil type is sandy, soft, or wet, you must consider adding concrete blocks or pier blocks
under corners of pergola to prevent sinking into soil.
1.
Excavate enough dirt to create a flat and level platform.
2.
Spray Roundup weed killer herbicide on the excavated area to prevent weed growth inside your pergola area.
3.
Lay thick weed control fabric over the entire pegola platform. Overlap the fabric at least 6 inches where they join. Use U-
shaped lanscaping fabric nails to anchor the fabric to the ground.
Alternatively, you can excavate deeper, about 3 inches, lay the weed control fabric at the bottom and fill the excavated
area on top of the fabric with gravel up to your desired height.
