Tank Dimensions
*Model CDA-45 required.
Deadmen Anchors are beams of
reinforced concrete placed alongside
the tank in the bottom of the
excavation. The weight of the backfill
on the Deadmen Anchors provides
additional resistance to buoyancy
forces acting on the tank. Properly
installed Deadmen Anchors, when
used exclusively with Polyester
Hold-Down Straps and the supplied
hardware, prevent tank flotation and
cost less than a concrete bottom
hold-down pad. Best of all, there is no
delivery charge for Concrete Deadmen
Anchors when they are shipped on
the same truck along with a Highland
storage tank.
Standard Features
‹‹ Designed to work with standard
underground storage tanks from 500
to 50,000 gallons
‹‹ Utilize a 4,000 psi concrete mix
reinforced with #4 rebar
‹‹ Dimensions:
CDA-15: 120" L, 18" W, 12" H
CDA-45: 120" L, 36" W, 18" H
‹‹ Volume:
CDA-15: 15 cubic feet (approx.)
CDA-45: 30 cubic feet (approx.)
‹‹ Weight:
CDA-15: 2,200 pounds (approx.)
CDA-45: 6,500 pounds (approx.)
Note:
1. Above recommendations assume that tanks
are buried at least 36" deep, have at least one
tank-top Sump and are installed exclusively
with Highland Polyester Hold-Down Straps.
2. To be effective, Deadmen Anchors must be
placed outside the tank diameter and extend
the full length of the tank.
3. A limited number of Deadmen Anchors require
the installation of supplemental methods of
restraint, such as 8" grade-level reinforced
concrete pads (as recommended by
PEI RP100-11).
