Natural UV

You are here:

LimeTreePit Natural UV is a 40mm natural aggregate surface surround for planted trees. Surrounding the tree in a permeable construction which allows for water to feed the tree whilst keeping the tree pit free from rubbish and hazardous items. The structure allows rainwater to pass through being SuDS compliant. (Sustainable Drainage Systems) Available in a variety of colours due to the inclusion of a high performance UV stable resin the aggregate surface system. LimeTreePit is ideal for pedestrian and low vehicular traffic whilst still keeping the system decorative, functional, seamless and slightly flexible which is also low maintenance. Edgings created from brick, stone, timber or steel should be installed to retain and protect the system and prolong it’s life span.

Slip resistance

All LimeTreePit Natural UV aggregate blends have been tested for slip resistance in accordance with: BS 8204-6:2008+A1:2010 Appendix B. All aggregate blends achieved ’low potential for slip’ in wet & dry conditions. Application of LimeTreePit Natural UV Anti-Slip Aggregate broadcast onto the surfacing during installation will significantly increase the slip resistance of the surface in the wet and on steep gradients without substantial change to the appearance.

Resin & aggregate

LimeTreePit Natural UV uses 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 LimeTreePit mix blend swatch sheet for colour options). The LimeTreePit Natural 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 LimeTreePit Natural 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. Average rate for reference: 1.6m² @ 40mm

Please refer to:

Limegate Solutions LimeTreePit Natural 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

LimeTreePit Natural UV is designed for foot traffic and occasional low vehicular traffic.

Please refer to:
Limegate Solutions LimeTreePit Natural UV Base Build Up Sheets for individual substrate requirements.
