MiTek’s Epoxy
The EBP44T-TZ Elevated Post Base is an economical solution for supporting
4x4 posts at the minimum 1 inch above the concrete foundation as required
by the building code. For applications where uplift loads are not present, the
EPB44T-TZ can be installed directly into a hole predrilled in a pier block or
concrete foundation as shown in Figure A below. To resist uplift loading, the
EPB44T-TZ must be cast into concrete or epoxied into place as shown in
Figure B below.
Materials: 12 gauge
Finish: G-185 galvanizing U-bracket; Hot-dip galvanized threaded rod,
nuts, washers
Codes: IBC, FL, LA
Installation:
• Use all specied fasteners. See Product Notes, page 18.
• Drilled Hole – No Uplift Resistance
– Drill 5/8" diameter hole into cured concrete 4" deep.
– Insert threaded rod of EPB44T-TZ into hole and adjust nut
to desired height.
– Install 4x4 post and fasten with (8) 10d common nails.
• Embedded In Concrete – Uplift Resistance Installation
– Adjust nut for desired height.
– Insert threaded rod with nut and washer into wet concrete.
– Provide temporary support to post base (if needed) to maintain
vertical and horizontal position.
– After concrete has cured, install 4x4 post and fasten with
(8) 10d common nails.
• Epoxied Into Place – Uplift Resistance Installation
– Drill 3/4" diameter hole into cured concrete 4" deep.
– Clean hole as per MiTek’s recommendations.
– Adjust nut for desired height.
– Fill the hole 3/4 full with MiTek Epoxy. Visit MiTek-US.com for
proper installation procedures and injection of MiTek epoxy products.
– Insert threaded rod with nut and washer into hole, pressing down
until the washer is rmly seated on the concrete.
– After epoxy has cured, install 4x4 post and fasten with
(8) 10d common nails.
• Not recommended for fence posts or other unrestrained
(not xed or fastened at top) applications. These anchors
are not designed to resist overturning (moment) loads.
