Installing Benches and Site Furnishings using an Expansion Screw
Expansion screws should only be installed in fully cured concrete that is at least 4” thick. All measurements in this installation guide assume a bare, level concrete surface.
Check for hazards
Always check for hazards such as water pipes, gas lines, and underground wiring before drilling.
Clean the surface
Dirt and debris can affect the line of sight and disrupt placement of the bench.
Use a broom or pressure washer to clean the concrete surface prior to bollard installation.
Study the site plans
Site plans are generally created by the architect of the project.
Refer to site plans, or place the bench where is to be installed, and mark the locations of each anchor.
For secure installation, ensure there is a minimum radius of ¾”1 of solid concrete around each mark.
Drill the hole
Create pilot hole
Tap a pilot divot hole in the center of each mark.
This will prevent the hammer drill or rotary hammer from drifting while boring the hole.
Set the depth control on the hammer drill (or rotary hammer) to 3-3/16″
If depth control is not available, mark 3-3/16″ on the masonry bit.
Drill the hole
Drill a hole that has a 9/16″ diameter and 3-3/16″ depth.
Drill on high speed, using the hammer function if available.
Check the masonry bit often to ensure it remains free of debris.
Secure the Bench
Clear the hole
Clear the hole of all debris and/or standing water using the vacuum.
Place the bench and set the expansion screws
When ready to install, remove the bench from any packaging.
Place the bench over-top of the holes and confirm bench is level and holes are placed correctly.
Insert an expansion screw into the hole. Hold the washer of the screw in place with a wrench, and then tighten the bolt with another wrench or hex socket to expand the sleeve and secure the anchor.
Repeat with the other expansion screws.
Inspect the installation
From a distance, examine the plane of view.
Ensure the bench is level.
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.
