Bound UV

You are here:

LimeGrid Bound UV is a Resin Bound Surfacing installed at 25-30mm onto a 40mm depth high performance grid made from recycled polypropylene. Initially designed as a standalone product for car-parking, LimeGrid Bound UV has adapted to be suitable for pathways and drive on / drive off vehicular usage. Where there is limited access to install a granular or macadam binder course the ease of install and flexibility for the contractor makes this system an environmentally friendly alternative. The structure allows rainwater to pass through being SuDS (Sustainable Urban Drainage) compliant. Available in a variety of colours LimeGrid Bound UV is ideal for pedestrian and low vehicular traffic. LimeGrid Bound UV is decorative and functional, seamless and slightly flexible and requires low maintenance. Edgings created from brick, stone, timber or steel should be installed to retain and protect.

Resin & aggregate

LimeGrid Bound UV resin is a UV resistant resin and will not yellow on exposure to UV light. This is a more attractive option than some other types of resin which can yellow and dramatically alter the appearance of the finished surface. The resin is formulated using aliphatic HDI which will not deteriorate or become brittle when exposed to UV light when tested to BS EN ISO 16474-3 method A The performance and appearance of the finished surface is dependent on the aggregate used (see LimeGate Solutions LimeGrid Bound UV mix blend swatch sheet for colour options). The LimeGrid Bound UV Aggregate blends have been designed to achieve strength, resilience, porosity and decoration.

Please Note:

Natural aggregates may contain small amounts of iron which can produce rust staining when exposed to air and water; standard LimeGrid UV blends contain aggregates selected for infrequency of incidence of staining but iron may be present in any natural aggregate. The presence of iron cannot be identified before use and Limegate Solutions cannot accept responsibility for any loss or damage suffered as a result of staining.

Coverage rates for individual blends can vary. Please refer to the Limegate Solutions LimeGrid Bound UV Mix Blend & Aggregate sheet. Coverage is based on application to a smooth flat surface and will vary when applied to undulating surfaces, according to compaction, and to the aggregate grading, which can change from batch to batch. Please contact us if you have any queries.

Working times & temperatures

Working time is affected by temperature; at temperatures above the maximum recommended 25°c the pot life and working time may be insufficient to allow a wet edge to be maintained. Do not therefore proceed when product and/or air temperature exceeds recommendations. The air temperature must be monitored during application and work should stop when the temperature exceeds recommendations. Care must be taken to keep materials as cool as possible in warm weather.

At low temperatures 5°C and below the resin will not flow sufficiently to achieve a smooth finish and work should not proceed.

Substrate requirements

LimeGrid Bound UV is designed for foot traffic and occasional vehicle traffic such as on domestic driveways, residential developments with light domestic traffic or car parking bays. It is however, not a road surface for heavy volumes of domestic or commercial traffic. Heavier vehicle traffic, including heavy impact and high point loading will damage the surface and may result in failure. Due to the destructive scuffing forces created by power steering (e.g. three point turns) in car parks or on driveways where cars will repeatedly turn within a confined area, localised wear is more likely.

Site attendance

When on site Limegate Solutions representatives are if asked, able to give a general indication of the correct method of installing Limegate Solutions products. It is important to bear in mind that Limegate Solutions is a supplier and not an application contractor and it is therefore the responsibility of the contractor and his employer to ensure he is aware of the correct practices and procedures to ensure the correct installation of the product and that liability for its correct installation is with the contractor and not with Limegate Solutions Ltd.
