Driveway & Ramp Design
A well-designed driveway is more than just a path to your garage — it's a structural element that must support repeated vehicle loads, manage stormwater runoff, and maintain safe gradients for pedestrian and vehicle access. Proper engineering prevents cracking, settlement, and drainage issues that can be costly to repair.
Our engineers design driveways and access ramps that account for soil conditions, traffic loading, gradient requirements, and council specifications — delivering durable, long-lasting solutions for residential and light commercial applications.
Driveway Types
Plain Concrete
Standard broom-finished concrete driveway. Cost-effective, durable, and low maintenance. Engineered for vehicle loads with appropriate thickness, reinforcement, and joint spacing.
Exposed Aggregate
Decorative finish revealing natural stone aggregate. Provides excellent slip resistance and visual appeal. Same structural requirements as plain concrete with surface treatment specification.
Stamped & Coloured
Patterned concrete mimicking pavers, stone, or brick. Combines the strength of concrete with decorative finishes. Requires careful joint planning to avoid cracking through patterns.
Asphalt
Flexible pavement suitable for larger driveways and rural properties. Cost-effective for long runs. Requires engineered subbase preparation and edge restraint design.
Ramp Gradient Standards
Access ramps and steep driveways must comply with strict gradient requirements to ensure safe vehicle and pedestrian access. Australian Standards and local council regulations specify maximum gradients, transition zones, and sight distance requirements that must be incorporated into the design.
Vehicle Access Ramps
- Maximum gradient 1:5 (20%) for residential driveways
- Transition grades at street and garage entries
- Anti-slip surface finishes for steep grades
- Sight distance triangles at boundary crossings
Pedestrian Ramps
- Maximum gradient 1:14 for DDA-compliant access
- Landings required every 9m of ramp length
- Handrail and balustrade requirements per AS 1428
- Tactile ground surface indicators at transitions
Drainage Considerations
Proper drainage design is critical for driveways and ramps to prevent water pooling, erosion, and damage to the pavement structure. Every driveway must be designed with appropriate cross falls, longitudinal falls, and collection systems to manage stormwater effectively.
- Cross fall design (minimum 2%) to direct water to collection points
- Channel drains and grated trenches at garage entries and low points
- Subsoil drainage beneath driveways on reactive or clay soils
- Stormwater connection to council drainage infrastructure
- On-site detention (OSD) requirements where applicable
