A solid foundation is necessary to prevent settling and tiling of each project. We recommend using a
leveling pad, unless local building code requires you to pour a concrete foundation or build another type
of foundation.
***Fire rings should be placed on stone, dirt, or sand surfaces. Pavers or concrete can be
installed around fire rings, but should not be under fire rings. Fire rings should not be placed on wood or
composite decking surfaces.
FOUNDATION:
• Choose the location for the completed project; place and mark the position of the base layer
of blocks. Once marked, remove the blocks and the organic top soil within the marked area.
• If applicable to your area, create a leveling pad with a non-frost susceptible, well graded,
compacted angular gravel-sand mixture with fines (GW as per ASTM D248). The leveling pad
should be a minimum of 4 to 6 inches thick. For leveling pads greater than 8” thick, the fill
material shall be placed in more than one lift. Each layer or lift of fill material shall be leveled
and compacted to a 95% Standard Proctor density before moving on.
• Once the top layer of fill material is compacted and level, place the base layer of blocks.
The base layer should sit 1 to 2 inches below grade to help further prevent shifting. Use
additional fill material to level the base layer as needed.
* If a concrete slab is required, prepare a leveling pad using the procedures listed in the paragraphs above. The
concrete shall have a minimum compressive strength of 2500 psi. A 4-inch thick concrete slab should be more
than sufficient. A thickened edge and reinforcement of the leveling slabs may be required. Please consult a
professional engineer for specific requirements.

It is the responsibility of the owner to ensure compliance with all applicable laws, codes and regulations
for any project. Proper safety precautions must be taken prior to and during the construction of each
project. Please follow standard safety guidelines and wear necessary protective equipment when
building and using your new backyard addition.

TOOL CHECK LIST
• Please research and
follow local building
codes prior to the
excavation, construction
and assembly of your
project.
• Exercise caution when
you work with concrete
block designs.
Wear protective safety
equipment such as safety
glasses, dust masks,
gloves and a hard hat.
• Whether you plan to build
the project yourself or to
hire a professional, every
project requires a call to
mark your utility lines.
