Lay a resin-bound driveway.

This installation is particularly popular in the UK due to its compliance with drainage regulations and its ability to transform the look of a property instantly. Whether you are looking to replace a cracked concrete drive or create a modern entrance for a new build, understanding the process and costs is essential for a successful project.

What Does the Work Involve?

• Site Survey and Preparation: Assessing the existing ground conditions, levels, and drainage requirements.
• Excavation: Removing the old surface and digging down to a required depth (usually 200mm-250mm) if a new sub-base is needed.
• Sub-base Installation: Laying and compacting MOT Type 1 followed by a binder course of open-graded macadam to ensure permeability.
• Edge Restraints: Installing brick, stone, or aluminium edging to create a frame that holds the resin in place.
• Mixing: Using a forced-action mixer to combine the kiln-dried aggregates with a two-part UV-stable polyurethane resin.
• Laying and Trowelling: Spreading the mixture evenly and hand-finishing the surface to a depth of 15mm-20mm.
• Curing: Protecting the area while the resin sets, typically requiring 6 to 24 hours depending on the temperature.

Typical Costs

The cost of a resin bound driveway varies significantly depending on whether you are "overlaying" an existing solid base or requiring a full "dig-out" and new sub-base construction. Prices below include VAT and professional labour rates for 2025/26.

Several factors influence the final price, including the size of the area (larger drives often have a lower cost per square metre), the choice of aggregate (rare or imported stones cost more), and the complexity of the driveway's shape.

Pro Tip: Always insist on UV-stable resin. While non-UV versions are cheaper, they will turn yellow or "tea-coloured" within months when exposed to UK sunlight, ruining the aesthetic of your choice of stone.

How Long Does It Take?

• Preparation & Groundworks: 2–4 days (depending on the extent of excavation and weather).
• Installing Edging: 1 day.
• Resin Application: 1 day for a standard 50m²–80m² driveway.
• Curing Time: 6–12 hours for foot traffic; 24–48 hours before driving vehicles onto the surface.

DIY or Professional?

Resin bound installation is strictly a professional task. The materials have a very short "pot life," meaning they must be mixed and trowelled within minutes before they begin to set. If the "wet edge" is lost during installation, you will be left with visible lines and patches that cannot be easily fixed.

Professional installers use specialized forced-action mixers; standard cement mixers are not sufficient as they do not coat the aggregate evenly. Furthermore, a professional install ensures the surface remains porous and complies with UK Sustainable Urban Drainage Systems (SuDS) standards.

Choosing the Right Tradesperson

• Check Equipment: Ensure they use a forced-action mixer, not a standard drum mixer.
• UV Stability: Confirm in writing that they are using UV-stable aliphatic resin.
• Portfolio: Ask to see local projects that are at least 2-3 years old to see how they have weathered.
• Insurance: Verify they have public liability insurance and offer a guarantee (typically 10 years).

• Are you trained by a specific resin manufacturer?
• Will the base be permeable (SuDS compliant)?
• How do you handle "day joints" if the project takes more than one day?
• What depth will the resin be laid at? (Standard should be 15mm-18mm for drives).

UK Regulations

Resin bound surfacing is one of the few materials that helps homeowners comply with UK planning laws regarding front gardens. Since 2008, regulations have focused on reducing surface water runoff into the main sewer system.

• SuDS Compliance: Because resin bound is porous, water drains through it into the ground. This means you generally do not need planning permission.
• Drainage: If the driveway is not porous (resin bonded rather than bound), you must install a soakaway or drainage channel to comply with the law.
• Building Regs: Ensure any changes to the driveway do not create a trip hazard at the threshold of your property (Part M compliance).

Common Problems

• Reflective Cracking: If the resin is laid over a base that moves or has existing cracks, those cracks will eventually show through the resin surface.
• Iron Spotting: Some cheaper aggregates contain natural iron which can rust and leave orange spots; ensure your installer uses "cleaned and dried" specialist aggregates.
• Clouding/Blooming: If it rains during installation or while the resin is curing, the moisture reacts with the chemicals, causing a white, cloudy finish.
• Loose Stones: Usually caused by an incorrect resin-to-stone ratio or using a standard cement mixer which didn't coat the stones properly.
