Bollard Installation

Not automatically. Impact performance depends on vehicle mass, speed, angle, pipe, foundation, reinforcement, soil, spacing, and stand-off. A concrete-filled pipe can deter low-speed contact but is not represented as crash-rated without accepted test or engineered evidence. Harrowgate installs the specified system for the defined protection objective.

Depth and diameter depend on bollard type, impact demand, soil, frost, slab condition, projection, and foundation design. Surface-mounted and embedded systems transfer loads differently. Harrowgate follows the structural or proprietary detail, verifies excavation and reinforcement, and does not use a universal depth for every site.

Yes, if scanning and design confirm slab thickness, reinforcing, edge distance, waterproofing, and anchor capacity. Options include core-drilled embedded posts, surface-mounted base plates, or new isolated foundations through the slab. Harrowgate restores joints and waterproofing and avoids post-tensioning, conduits, and structural conflicts.

Spacing comes from the protection design, vehicle geometry, and required pedestrian or accessible clear route. It must prevent unwanted vehicle passage without blocking mobility devices, doors, fire access, or service operations. Harrowgate lays out the complete line in the field and checks clear openings before foundations are placed.

Removable units suit fire, maintenance, seasonal, event, and controlled service access. Sleeves need drainage, caps, debris control, secure locking, and a key-management plan. The removable unit and its receiver must still meet the required structural function. Harrowgate checks operation after surrounding pavement and finishes are complete.

Options include galvanizing, stainless steel, powder coating, compatible paint systems, and replaceable covers. Base detailing must shed water, seal pavement penetrations, and limit salt accumulation. Harrowgate protects finishes during concrete work, seals interfaces, and uses specified repair coatings on field damage or weld areas.

Only if the engineer or system detail confirms the foundation, steel, anchors, and surrounding slab remain sound. Vehicle impact often cracks concrete below the surface or elongates anchors. Harrowgate exposes and assesses the condition, removes damaged material, and rebuilds the foundation where capacity or alignment is uncertain.
