Hollow Mountable Kerbs for Vehicle Crossover Points
Hollow Mountable Kerbs are specially designed precast kerbs with a sloped or mountable profile. Unlike traditional vertical kerbs that create a sharp step, these kerbs feature a gentle incline that allows vehicles to cross over them safely when necessary, while still providing boundary definition during normal use.
At Majorcon Precast, our hollow mountable kerbs are engineered for the perfect balance of boundary definition and vehicle accessibility. Build with confidence. Build with Majorcon Precast.
Primary Uses
- Petrol station entrances, exits, and pump island approaches.
- Entrances to car parks where kerb lines must be maintained.
- Residential and commercial driveway crossovers.
- Paths requiring occasional vehicle access.
- Service yards and loading areas with intermittent vehicle movement.
- Dropped kerb sections for mobility access.

Why Choose Our Hollow Mountable Kerbs
- Gently inclined design allows vehicles to cross safely without damaging tyres, suspension, or the kerb itself.
- Lightweight construction makes handling and installation easier while maintaining structural integrity.
- Smooth ramp effect eliminates the harsh step found in standard vertical kerbs.
- Maintains visual edge definition while permitting occasional access when needed.
- Ideal for entrances, crossovers, and areas where vehicle access is required but kerb lines must be maintained.
Frequently Asked Questions
Mountable kerbs solve the challenge of maintaining kerb lines while allowing vehicle access. Here are answers to the questions we receive from architects, civil engineers, and site developers.
While both allow vehicle access, they serve different purposes:
| Feature | Hollow Mountable Kerbs | Standard Drop Kerbs |
|---|---|---|
| Profile | Sloped along entire length | Vertical with dipped section |
| Vehicle Crossing | Can be mounted anywhere along length | Vehicles must cross at the dipped section |
| Typical Use | Service stations, wide access areas | Individual driveways, pedestrian crossings |
| Aesthetic | Continuous kerb line appearance | Visible break in kerb line |
| Installation | Installed as continuous run | Requires transition units |
Hollow mountable kerbs are ideal where vehicles may need to cross at various points along the kerb line, such as petrol station forecourts.
Hollow mountable kerbs are designed for:
Cars and small vans: Safe mounting at low speeds
Delivery vehicles: Occasional crossing when accessing service areas
Emergency vehicles: Quick access when needed
Service trucks: Slow, careful maneuvering
For areas with frequent heavy vehicle crossing (daily HGV access), we recommend consulting our technical team about reinforced mountable options or alternative access solutions.
Hollow core refers to the internal design of the kerb, which features voids or cavities rather than being solid concrete throughout. Benefits include:
Reduced weight: Easier handling and installation without heavy equipment
Lower transport costs: More kerbs per truckload
Adequate strength: Engineered to maintain structural integrity despite hollow sections
Material efficiency: More sustainable use of concrete
Despite the hollow design, these kerbs are fully engineered to withstand vehicle loading when properly installed.
Yes, they are an excellent choice for residential driveway crossovers, particularly where:
The driveway entrance is wide and vehicles may enter at slightly different angles
A continuous kerb appearance is desired without a visible “dip”
Occasional larger vehicles (delivery trucks, moving vans) need access
The property has a curved or angled driveway approach
For standard residential driveways with a single defined entrance, traditional drop kerbs may also be suitable. Our Sales Team can advise based on your specific layout.
Installation follows a similar process to standard kerbs:
Excavation: Trench dug to required depth
Base preparation: Compacted sub-base and concrete bedding
Positioning: Kerbs set to correct line and level
Haunching: Concrete support to the back of the kerb
Transition: Standard vertical kerbs at ends where mountable section finishes
The hollow core design means these kerbs are lighter and easier to maneuver into position than solid equivalents.
Yes, drainage should be considered:
Water flow: The sloped profile may affect how water runs to drainage points
Low points: Ensure mountable sections don’t create unintended water pooling areas
Integration: Coordinate with overall site drainage design
For service stations and parking areas, we recommend integrating mountable kerbs with appropriate drainage channels to ensure effective stormwater management.
Hollow mountable kerbs are designed for occasional crossing, not continuous parking. Considerations:
Parking against: Vehicles can park with wheels against the kerb (as with standard kerbs)
Parking on: Not designed for vehicles to park on top of the kerb for extended periods
Repeated crossing: Frequent, high-speed crossing by heavy vehicles may cause wear
For areas where vehicles will regularly park with wheels on the kerb, we recommend our solid mountable or heavy-duty options.
