Installing the R-7512 T-Head Mooring Bollard with Epoxy Resin
The R-7512 T-Head Mooring Bollard is a specially-designed marine bollard for carrying wire ropes. The bollard has a “T” shaped top, a simple and efficient shape for securing marine vessels to a wharf, and is suitable for steeper rope angles.
The T-Head Mooring Bollard has two mounting options: it can be surface mounted, or recess mounted. Recess mounting is generally recognized as superior, as recessing the base prevents the bolts from working loose. In either case, the bollard is fixed with anchors—either cast-in or using epoxy and resin.
For an epoxy or resin installation, use an appropriate high strength epoxy or resin as determined by a site engineer.

- Reliance Foundry Co. Ltd. is not responsible for installation and cannot offer guidance on specialized applications. Please refer to the product warranty for specifics.
Anchor Installation should be carried out by qualified personnel and under the supervision of the person responsible for technical matters of the site.
Use anchors supplied by Reliance Foundry.
Have a site engineer confirm that the strength class of the concrete used is appropriate for this bollard.
Study the site plans
Study the site plans and mark the intended location of each bollard on the plan.
Check for hazards
Always check for hazards such as water pipes, gas lines, and underground wiring before digging
Note: You may need a permit to dig to certain depths or in certain locations.
Preparation for epoxy / resin installation
Epoxy/resin is used to bond the anchors to existing concrete. If existing concrete is not being used, follow applicable instructions in the cast-in installation instructions to pour appropriate concrete pad. Allow to cure completely before proceeding.
Clean the area of all debris.
Use anchor template to mark positions of holes.
Use a hammer drill to drill holes 30 mm [1.18"] in diameter and 432 mm [17"] deep.
- Use a continuous flow of water to reduce heat generation between drill bit and concrete.
- Slowly drill hole to required depth.
Once hole has been cored, roughen inner surface of the hole using a rotary hammer drill bit.
Clean holes using a pressurized water flow until water runs out of the hole clear.
Insert steel brush to the bottom of the holes, twist during removal.
Blow oil-free compressed air two times into the drilled hole.
Repeat cleaning using water and air two more times.
Inject epoxy / resin
Follow epoxy or resin manufacturer’s instructions for injecting into the bore holes. Fill bore holes up to 2/3 full.
Clean each anchor and dry completely.
Insert into each core while twisting slowly.
Set the anchor to the appropriate embedment depth and leave for the necessary working time, according to the manufacturer’s guidelines.
After install, fill the annular gap with epoxy/resin.
Use an anchor template to stop movement of anchors after installation.
Leave anchors to cure according to manufacturer’s guidelines. Do not touch anchors during curing time.
Cover anchors with a suitable cap to avoid damage.
Ensure all anchors are straight and level and at the appropriate protrusion length for the bollard installation.
Grout and place the bollard
Roughen the surface of the concrete and remove all debris from the surface.
Clean the base of the bollard of all grease, dirt, loose rust and scale.
Align the bollard on the anchors and shim to leave a gap between the base and the concrete surface.
- Use either removable shims, or corrosion-free shims if non-removable.
Check the alignment of the bollard using a level.
Use boundary forms to isolate the area for grouting.
Follow grout manufacturer’s procedure for filling the grout.
Grout should be sturdy and caulked approximately 15 mm [0.6"] around the edge of the base of the bollard.
Place the grout at least 5 mm [0.2"] above the bottom of the base flange.
Cover immediately with wet rags or curing compound.
Allow grout time to cure completely.
Torquing to anchors
Once grout has cured, place provided washers and nuts and torque to 240 N-m.
Inspect the installation
From a distance, examine the plane of view.
Ensure the bollard is plumb.
Check the bollard for any signs of surface damage
Abrasions should be covered as soon as possible to prevent rust and ensure the proper life of the bollard. For damage repair or other servicing needs, please contact Reliance Foundry’s sales department.
Care and maintenance
Reliance Foundry manufactures its products to the highest design standards to ensure their durability. Reliance Foundry’s bollards are finished with long-lasting powder coating. In most North American environments, routine inspections and cleaning will ensure that bollards retain their aesthetic appeal. Proper care and maintenance are required to maintain the finish and ensure a full service life.
