How to Install Rubber Speed Bumps: Step-by-Step Guide
Rubber speed bumps are the most practical traffic calming solution for private car parks, industrial estates, and access roads. Unlike asphalt humps, rubber speed bumps require no road closure, no specialist machinery, and no hot works permit. A small team can install a complete system in a few hours.
What You'll Need
- Rubber speed bump modules (full section + end caps)
- Anchor bolts (typically M12 × 100mm or supplied with product)
- Rotary hammer drill with masonry bit (12–16mm diameter)
- Torque wrench
- Tape measure and chalk line
- Road marking paint and brush
- High-visibility jacket and appropriate PPE
Step 1: Site Assessment
Assess the installation site for surface type (tarmac, concrete, block paving), drainage (ensure the hump line does not block water flow), approach sight lines (drivers should have 20–30m of clear visibility), and calculate width requirements. Browse our speed bump range to find the right product.
Step 2: Mark Out the Installation Line
Use a chalk line to mark the centre line of the speed bump across the full carriageway width at 90° to traffic direction. Mark the position of each module and the anchor bolt hole positions.
Step 3: Pre-Drill Anchor Holes
Drill anchor holes to the depth specified by the manufacturer (typically 80–120mm for tarmac, 100–150mm for concrete). Clear each hole with compressed air — debris prevents the bolt from seating correctly.
Step 4: Position End Caps First
Start with the end caps at each kerb edge. These provide a ramp profile at the sides, preventing wheel catch and pedestrian trip hazards. Insert anchor bolts hand-tight.
Step 5: Install Middle Sections
Working from one end cap towards the other, place each middle module with the interlocking lip engaging the previous module. Insert bolts hand-tight. Do not tighten bolts until all modules are in position.
Step 6: Torque All Bolts
Starting from the centre and working outward, torque each bolt to the manufacturer's specification (typically 25–40Nm for M12 bolts). Do not over-torque — this can crack the rubber module.
Step 7: Apply Road Markings
- Apply yellow or white hatching to the face of the speed bump
- Add "SLOW" or speed limit markings to the approach surface
- Consider retroreflective markers for night visibility
Step 8: Install Signage
Advance warning signage is strongly recommended even on private land. Use a "Road Hump Ahead" warning sign placed 20–30 metres before the hump.
Maintenance After Installation
- Inspect bolt torques after the first week of use
- Check for module movement, cracking, or edge lifting quarterly
- Individual damaged modules can be replaced without removing the entire hump
