SuDS permeable tree pit system consisting of recycled EPDM, SBR and rubber mulch, and a quality non-UV aromatic binder resin.
Suitable for both for new and established trees used in parks and street schemes, the system allows the tree to grow through the flexibility of the surface.
LimeTreePit Rubber & Mulch offers a flexible alternative to traditional tree pits. Provides an environmentally friendly system, using recycled EPDM, SBR and rubber mulch. Bound together to create a decorative, safe and low-maintenance system which is Sustainable Drainage System (SuDS)-compliant.
Suitable for pedestrian and low vehicular traffic, whilst still keeping the system decorative, functional, seamless and slightly flexible, and also low maintenance. The system consists of either rubber EPDM granules installed over SBR rubber granules or a full rubber mulch system. Both options use a quality, non-UV aromatic binder resin for pedestrian traffic. Available in a variety of colours, both from the standard range and bespoke designs on request.
Resin and aggregate:
The system uses a non-UV polyurethane binder, as used on playground surfaces, and is designed specifically for bonding rubber granules and mulch. The rubber binder is a single-component, moisture-curing, medium-viscosity polyurethane binder. The rubber EPDM layer as a topping/ wearing course is installed at 15 mm onto a suitable 25 mm SBR shockpad/ base (40 mm total). The rubber mulch is installed at 40 mm. Coloured EPDM granules are made from a compound of EPDM rubber, specialist pigment and UV stabilizers. The LimeRubber SBR shockpad/ base is a recycled tyre granulate suitable for base layer applications. The rubber mulch/ bark is processed to remove steel, fibre and dust to produce a clean, high-quality rubber granulate.
