Bollards / installation
Tools Needed for Installation
Cement mixing tub
Hole coring machine with 4" bit
Access to water hose
Materials to build brace
Installing into Existing Concrete Surface
Core holes no less than 3" diameter (4" recommended) and no less than 10" deep into surface.
Place bollard into holes making sure the bollard is level.
Fill holes with Por-Rok or epoxy grout. 32" of the bollard should remain above the surface.
Make sure bollard is level and held in place until the grout has completely set. An easy way to brace the bollard while the grout sets is to bolt two 1x4" boards together at one end and clamp them onto the legs of the bollard like a clothes pin.
Installing into New Concrete Surface
Place corrosion resistant sleeve (min. 3" inside diameter) in sand pour bed in exact location where rack will be installed. Make sure top of sleeve is at same level as desired finished concrete surface. Fill sleeve with sand to keep it in place and prevent it from filling with concrete.
Pour concrete and allow to cure.
After appropriate cure time, dig out sand from sleeves and insert racks, making sure they are level and at the appropriate height.
Place Bollards into holes making sure the rack is level.
