Simply dig out existing surfaces to 150mm depth as your starting point for a resin bound driveway. Type 1 MOT stone works brilliantly as your sub-base material – it's what most UK contractors swear by. Spread the stone in even layers, making sure to compact each one properly with a whacker plate. You'll want the surface dead level, so check it with a spirit level and clear off any bits and pieces.
For proper drainage (and to meet UK SUDS requirements), stick to permeable materials throughout. This helps avoid puddles forming on your drive when we get our typical British weather. Getting the sub-base right is crucial – skimp on this stage and you risk the whole driveway sinking or cracking down the line. Rather like building a house, it's all about getting the foundations spot-on.
Key Takeaways
Sub-Base Preparation for Resin Bound Driveways
- Dig out the existing ground 100mm to 250mm deep, depending on your soil type and intended usage (deeper for driveways that'll bear vehicles).
- Remove all loose material, weeds and rubbish – a spotless base is crucial for proper installation.
- Add Type 1 MOT stone in layers, roughly 50mm at a time. Compact each layer thoroughly with a vibrating plate – you should hear a change in tone when it's properly compacted.
- Use permeable materials that meet UK SUDS requirements – this prevents flooding and ensures proper water drainage through the sub-base.
- Check the finished surface with a straight edge. It should be level, stable and free from dips or bumps before you start laying the resin bound surface.
Suitable Sub-Base Materials
Sub-Base Options for Resin Bound Driveways
Tarmac and concrete serve as the main sub-base options for resin bound driveways, each offering distinct advantages.
Tarmac provides excellent permeability, meeting SUDS regulations for water drainage. Whilst 50mm depth is adequate, 100mm offers better stability. It works particularly well in British weather conditions, though proper edge restraints are crucial to prevent shifting. Tarmac must be laid on an MOT type 3 sub-base to ensure adequate support.
Concrete delivers superior strength for high-traffic areas. It requires a minimum 100mm depth and C35 strength grade. To prevent cracking, steel mesh reinforcement and repair mortar are essential at open bay joints.
Your choice between tarmac or concrete should reflect local conditions and usage requirements. The right sub-base is vital for ensuring your resin bound driveway remains durable and functional throughout British weather conditions.
Steps for Sub-Base Preparation
First, carefully remove existing surfaces like grass, soil or old paving through excavation.
Dig to a suitable depth – typically 100mm to 250mm – using proper equipment such as mini-diggers.
Clear away all debris to create a clean working area.
Next, lay your sub-base material in even layers.
Grade each layer properly and compact it thoroughly using a plate compactor or roller.
Keep an eye on moisture levels whilst compacting, as this affects the final result.
Check each layer after compaction for evenness and stability.
Test the density to ensure it meets UK standards.
Before moving on to the resin bound surface, give the sub-base a final inspection.
Look for any damage or loose material that needs addressing.
A properly prepared sub-base is crucial for a long-lasting driveway, as it provides the necessary support for the durable surface that the resin-bound system will create.
Take time to get this foundation right, and you'll avoid problems later.
Sub-Base Depth Requirements
Getting the right sub-base depth is crucial for a lasting resin bound driveway. For footpaths and patios, you'll need at least 100mm, whilst driveways need a minimum of 150mm. Use a properly compacted Type 1 MOT stone sub-base, typically laid between 150mm to 225mm deep. A well-prepared sub-base ensures the longevity of the surface and prevents issues related to poor installation. Additionally, proper edge restraints must be installed to contain the resin and prevent spreading.
The correct depth prevents common problems like sinking and cracking – much like building a house needs solid foundations. For tarmac surfaces, you'll want at least 50mm depth, or 60-70mm if using open-grade tarmac. If you're installing permeable grids, these need about 40mm depth, with 120-150mm of base material underneath.
When digging out your driveway, plan for a sub-base depth between 100mm to 250mm, based on what you're using it for. Think of a family car versus heavy vehicles – they need different levels of support. Always ensure thorough compaction, and get professionals to install the resin layer for best results.
Ensuring SUDS Compliance
Ensuring your resin bound driveway meets SUDS compliance is vital for both legal requirements and practical performance. The key lies in creating a proper permeable base using Type 1 MOT aggregate or open-textured binder course tarmac. Your base must effectively handle water drainage into the ground below.
For full compliance, you'll need a specialist mix of porous concrete or open-grade material laid over Type 3 MOT aggregate.
SUDS compliance offers real benefits: it reduces local flood risks and supports natural water management. A properly built base ensures your driveway drains effectively, preventing damage whilst helping natural groundwater levels. Additionally, a well-constructed permeable paving system can store significant amounts of water, aiding in groundwater replenishment.
Worth noting: SUDS compliance means you won't need planning permission for larger driveways, as they'll already manage rainwater at the source.
For materials, recycled aggregates work brilliantly – they're both cost-effective and fully compliant. A SUDS-compliant driveway needs less maintenance and helps manage urban water flow, making it a smart choice for UK properties.
Focus on these core requirements to ensure your resin bound driveway works properly and meets all environmental standards.
Common Installation Mistakes
Common Installation Mistakes for Resin Driveways
Getting your SUDS paperwork sorted is only half the battle – proper installation makes all the difference between a lasting resin driveway and a costly headache.
These crucial mistakes can wreck your driveway's stability and durability:
Shoddy Ground Prep
Skip proper excavation and compaction, and you're asking for trouble. Your base must be rock-solid.
Cheap Materials
Cutting corners on resin or aggregate quality is a false economy. Budget materials mean early repairs.
Wrong Depth
Lay it thinner than 15mm, and you'll likely face cracks and lifting. Proper depth is non-negotiable.
Missing Expansion Joints
Without these, your driveway can't handle temperature changes properly. Cracks will follow.
Poor Timing
Hot weather speeds up resin curing. What works on a mild day won't do in summer heat – timing matters. Additionally, ensuring a suitable permeable sub-base can enhance water drainage and prolong the lifespan of your driveway.
