Set the Foundation
To ensure the stability of the WedgeSmart DC, the foundation must be constructed
in accordance with the following guidelines:
Measure and Lay Conduit for Communication & Power
Assemble Rebar Mat
1. Place one layer rebar mat at 8-inch on center (OC)
2. Stagger rebar mat between anchor bolts.
3. Use rebar #5 (⅝ inch), Grade 40 or better.
Soil Density compacted to 95%
per ASTM-698
Excavate for Concrete Pad and Rebar Mat

and road surface grade
changes. The need for
recessed mounts may be
a site requirement.

CAUTION
Use the template to make sure rebar
#5 (⅝ inch), Grade 40 or better,
does not interfere with anchor bolts.
Also, note that the anchor holes cannot
be drilled with the chassis in place.

Min. Requirement: Use of 4 anchor bolts at each hinge location.
1" (25 mm)
Two ¾" anchor mounts for strap bracket. AVOID REBAR interference in this area.
• Excavate a hole for the foundation to house the rebar mat and anchor bolt
assemblies. Soil compression under and around the foundation shall be compacted
to a soil density of 95% of standard proctor (ASTM-698).
• Add gravel where necessary to ensure a solid soil base. Soil must be stable and adequate to support the
weight of the foundation.
NOTICE: Softer soils require a larger footing. Employ the services of a structural or civil engineer for site
specic considerations. In Northern latitudes, consider the frost line.
• The WedgeSmart DC must be installed on a level surface. The chassis and wedge plate must be
plumb, level and on grade with the roadway surface.
NOTICE: Be aware of low clearance vehicles, such as car haulers. Recess the concrete pad accordingly.
• Cure concrete properties, at minimum, 3000 psi with a smooth nish and proper drainage. Slope
drainage ¼-inch per foot within 2 feet of the operator (2 cm per meter).
• Use Anchor Kit MX3460 (Grade B7 threaded steel rod and HIT-RE500 Epoxy adhesive.
A minimum of 4 anchor bolts required to secure each hinge
(6 mounting holes available at each hinge).
