OPTION 1: ARROW FLOOR FRAME KIT:
(Order No. FB106-A or 68381-A)
Arrow has the best base for your building in this simple kit. It keeps stored items above the ground. This kit should be used with one
of the following:
A. To support a plywood deck B. To be filled with sand. We recommend the combined use of
1. an ARROW FLOOR FRAME KIT and 2. an ARROW ANCHORING KIT as an effective method of securing the building to the ground.
Allow 1 - 2 hours for construction.
OPTION 2: Wood Platform
If you decide to build your own foundation, be sure to select the appropriate materials.
These are the recommended materials for your foundation:
● 2 x 4's (5cm x 10cm) Pressure Treated Lumber ● 5/8" (1,5cm) 4 x 8 (122cm x 244cm) Plywood-exterior grade
● 10 & 4 penny Galvanized Nails ● Concrete Blocks (optional)
The platform should be level and flat (free of bumps, ridges etc.)
to provide good support for the building. The necessary materials
may be obtained from your local lumber yard.
To construct the foundation follow instructions and diagram.
Construct frame (using 10 penny galvanized nails)
Measure 16"/24" (40,6cm/61cm) sections to construct
inside frame (see diagram)
Secure plywood to frame (using 4 penny galvanized nails)
Allow 6 - 7 hours for construction.
OPTION 3: Concrete Slab
The slab should be at least 3" to 4" (8-10cm) thick. It must be level and flat to provide good support for the frame.
The following are the recommended materials for your foundation.
● 1 x 4's (2,5cm x 10cm) (will be removed once the concrete cures)
● Concrete ● Sheet of 6 mil plastic
● We recommend for a proper strength concrete to use a mix of:
1 part cement
● 3 parts pea sized gravel ● 2 1/2 parts clean sand
Prepare the Site/Construct a Foundation
1. Dig a square, 6" (15cm) deep into the ground (remove grass).
2. Fill up to 4" (10cm) in the square with gravel and tamp firm.
3. Cover gravel with a sheet of 6 mil plastic.
4. Construct a wood frame using four planks of 1x4 (2,5cm x 10cm)
lumber.
5. Pour in concrete to fill in the hole and the frame giving a
total of 4" (8-10cm) thick concrete. Be sure surface is level.
Allow 3 - 5 hours for construction and a week for concrete curing time.
Note: Platform/Slab will extend 9/16" (1,4cm) beyond floor
frame on all four sides. Seal this 9/16" of wood with a
roofing cement (not included), or bevel this 9/16" of
concrete when pouring, for good water drainage.
