Tree Pits Using Resin Bound Surfacing around tree pits provides an easy to maintain surface with no loose stone, avoiding trip hazards and the build up of litter associated with traditional metal grilles/shingles and facilitating easy cleaning by mechanical sweepers. The open texture of the paving also allows trees to grow, with the aggregate peeling back as the trunk expands.

A wide range of aggregate is available for tree pits including natural, peas, gravel and rounded buff. Typically stone sizes of 6-10mm are used to ensure a highly porous structure allowing water to freely permeate through to the tree roots.

Sub Base A sub base of 150mm well compacted graded aggregate (no fines) on top of a suitable depth of well compacted tree soil or similar covered with a water permeable membrane to prevent upward movement of the fine soil and tree roots.

Performance The tree pit system uses specifically selected aggregates to allow water to flow through to the roots while maintaining a highly durable surface.

The cured paving has a texture finish resistant to degradation caused by weather and UV radiation, oil, fuel and some commonly used solvents. Under normal usage the paving is expected to have a life span at least equivalent to conventional paving materials.

SUDS – Sustainable Urban Drainage System The environmental agency has recognised the need to manage water surfacing.

Drystone’s resin bound system is permeable and if the surface such as open textured macadam, will prevent standing water drainage to the underlying ground.

Building regulations for England show the preferred disposal methods are: 1.

Infiltration on site

2.

Discharge to water course

3.

Connection to a sewer

Specifying Drystone’s resin bound surfacing system will demonstrate to the implementation of a sustainable drainage system.

About us Drystone (UK) Ltd specialises in resin surfacing systems and has over 15 years contracting experience with a wealth of knowledge.

Drystone supplies and lays resin based surfacing systems throughout the UK offering a wide range of colours and aggregate types. Our surfacing can be used for coloured borders or decorative illustration within the surfacing itself, adding an attractive feature to any landscape environment.

We are also able to produce any logo designs, shapes and stencils as required.

Our contracting experience has been used on many large commercial sites from new build to regeneration products, schools and care homes, as well as private drives, parks, car parks, footpaths, tree pits and many more.

We give you the opportunity to specify a real alternative to conventional paving, offering a full supply and lay service.

Our Resin bound surfacing is fully permeable and gives you a hardwearing, highly attractive durable new surface which is virtually maintenance free.

Resin Bound Surfacing

Performance

Drystone resin bound surfacing is compromised of graded aggregates, bound with a clear polyurethane resin binder, which allows the aggregate colour to show through. It is based upon BS 4987 (the British Standard specification for coated macadams) with bitumen replaced by a clear binder and is designed for driveways, mews, parking areas or where the application of hot applied may not be feasible.

The durability of Drystone resin bound surfacing will depend on site conditions and it is anticipated that the surface will have a similar service life to that of conventional bituminous macadam made with the same aggregate.

Drystone resin bound surfacing provides a hard-wearing textured surface, resistant to the weathering effect of UV radiation from sunlight and to softening or degradation by oils, fuels and some commonly used solvents.

Application Drystone resin bound surfacing aggregate and binder system is mixed on site immediately prior to laying in a forced action mixer, mixing the aggregate and resin together.

The mixed material is laid to a depth of 15-18mm on bituminous or concrete base courses and float finished. The depth and composition of the underlying construction will be dependant on whether the surfacing is intended for vehicular or pedestrian traffic.

The curing time of the surfacing is controlled to suit the prevailing site conditions by the incorporation of additives at the mixing stage.

Specification Guidelines Base course bituminous: Hot-applied bituminous base course or surface course to BS594 or BS4987.

Concrete: Concrete to BS328, new and existing surfaces to be prepared in accordance with construction industry research and industry information services report 184.

The surface regularity for the base course construction should be + 6mm

Resin Surface Dressing

Resin Surface Performance

Resin surface dressing is a hard wearing, easy to use cold applied polyurethane/ epoxy resin surface dressing used for bonding specially selected aggregates to macadam, asphalt, concrete or metal surfaces. It can be applied to new constructions or to existing surfaces.

The durability of resin surface dressing will depend on site conditions and it is anticipated that the surface will have a similar service life to that of conventional surfaces made with the same aggregate. Resin surface dressing is resistant to the weathering effects of UV radiation, from sunlight to softening or degradation of oils, fuels and some commonly used solvents.

Resin surface dressing can be used with a wide range of natural and pigmented aggregates for both decorative and slip resistant dressings.

The resin components are simply mixed with a drill powered mixer and is then spread over the surface using a serrated edge squeegee at a rate of 1.5-1.8kg per m2 depending on surface condition and aggregate used.

The cured resin surface dressing systems give a durable, textured surface which is ideal for pedestrian areas, pathways, cycle ways, car parks, traffic calming, colour demarcation, and anti-skid applications.

Using resin bonded surface dressing means no sticky black binder will be seen as can happen with conventional bituminous surface dressing systems.

Application

Aggregate is then broadcast to excess over the spread resin by hand so that the resin layer is fully covered. Typical application rates for 1-4mm aggregates are 8-10kg per m2. Once the resin is sufficiently cured, the excess aggregate is removed by hand brushing or mechanical sweeping, to ensure all the loose stone is removed.

Surface Preparation Porous surfaces should be sealed prior to resin application sealing compound and be of sound construction and of regular profile. Metal surfaces should be treated with a suitable metal primer.

Base Course The depth and composition of the underlying construction, will be dependent upon whether the surfacing is intended for vehicular or pedestrian traffic. A typical base build up for pedestrian and light traffic areas are bituminous – hot rolled asphalt to BS594.
