A telescopic bollard should typically be installed to a depth of 800 mm to 1,200 mm (approximately 32–48 inches), depending on the model, bollard height, and manufacturer’s specification. The correct depth ensures stability, smooth operation, and impact resistance once fitted.
Here’s what to consider during installation:
- Foundation Depth – Most standard driveway or commercial telescopic bollards require a concrete foundation around 1 m deep and approximately 300 mm × 300 mm wide.
- Ground Conditions – Softer ground or high-traffic areas may need reinforced concrete or a deeper foundation for extra strength and rigidity.
- Drainage – Telescopic bollards include a built-in or gravel soakaway at the base to allow water to drain freely and prevent freezing or sticking in winter.
- Alignment – The bollard casing must be installed vertically and level so the post raises and retracts smoothly without friction.
- Surface Finish – Once set, the top of the bollard housing should sit flush with the surface for a neat, trip-free installation.
At Aremco Barriers, all UK-manufactured telescopic bollards are supplied with installation guidance, foundation dimensions, and drainage recommendations. Made from galvanised and powder-coated steel, our bollards are engineered for secure, long-life performance across driveways, car parks, and commercial sites.
