CONCRETE BLOCK MATERIALS
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.
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 nes (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 ll
material shall be placed in more than one lift. Each layer or lift of ll material shall be leveled and
compacted to a 95% Standard Proctor density before moving on.
• Once the top layer of ll 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 ll
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 sufcient. A thickened edge and reinforcement of the leveling slabs may be required. Please consult a
professional engineer for specic requirements.

your yard. Check out the Progress Bar at the bottom of each page to track your advancements as you
complete each phase of your project!
INSTRUCTIONS:
• Please research and fol-
low local building codes
prior to the excavation,
construction and assem-
bly of your project.
• Exercise caution when
you work with Concrete
Block designs. Wear pro-
tective safety equipment
such as safety glasses,
dust masks, gloves and a
hard hat.
• Whether you plan to
build the project your-
self or to hire a profes-
sional, every project
requires a call to mark
your utility lines.
BEFORE YOU BEGIN:
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.
RESPONSIBILITIES:
Chisel
Standard Hammer
This is an advanced to expert plan; cutting or chiseling block will be necessary for assembly. A
block tter and circular saw with masonry cutting blade are ideal tools to work with. Necessary
cuts will be called on the plans.
