The Addastone resin bonded surfacing system provides an attractive, hard wearing, low maintenance surface by bonding or fixing loose gravel aggregates to concrete, asphalt, wood or metal. Aggregates bonded with resin to a surface give the appearance of loose gravel without the many maintenance problems. A wide range of natural and recycled aggregates can be resin bonded to a variety of surfaces making it ideal for heritage sites, landscaping schemes, parks, paths, driveways, roads and visitor attractions that want the look of loose stone but the convenience of fixed paving.

Major Benefits

• Aesthetically pleasing – decorative natural appearance
• Durable – hard wearing and resilient
• Fixed – does not move, migrate, or wash away
• Low maintenance – requires only occasional sweeping and or pressure washing
• Anti-slip – textured aggregates provide a good anti skid surface
• Apply to asphalt, concrete, timber and steel surfaces.

Life Expectancy

Resin bonded gravel surfaces are very resilient. However life spans will depend on usage and choices of aggregate. Typical examples of expected life are as follows:
• Footpaths using a 2-5mm Brittany Bronze: 8-15 Years
• Domestic Drive using a 1-3mm Chinese Bauxite: 8-15 Years
• Car Parks using a 1-3mm Guyanan Bauxite: 5-10 Years
• Roads using 1-3mm Chinese Bauxite 5-8 Years

General Cleaning

Oil, dirt or other common stains should be removed from resin bonded aggregate surfaces by applying a suitable household detergent or similar degreaser.

Resin bonded gravel driveways, paths or paved areas should be swept occasionally to remove loose stones, they can also be cleaned using pressure washers to remove dirt and detritus.

To protect surfaces from staining and to aid cleaning and removal of chewing gum a coat of Addatone Surface Protector >>> should be applied.

Maintenance

Newly treated resin bonded gravel surfaces must be swept to remove excess aggregate as soon as possible using a mechanical road sweeper* or by hand. A further sweep should be carried out after 1 – 3 months to remove remaining loose stones.

A visual examination should be carried out to check that no or very little aggregate is left as this could result in the bonded aggregate splitting and working out of the resin. This could negate on any guarantees agreed with the Addastone installer.

*Mechanical sweepers using metal bristles must not be used.

Addastone surfaces are resistant to acid and alkali. However some staining may occur.

Alternatives: Resin Bonded or Resin Bound?

What is the difference between Addaset and Addastone?

There are two different systems that use resin to fix gravel aggregates. These are:

Resin Bonded (Addastone) is a scatter system which provides texture and the appearance and loose gravel. Simplistically it is a layer of resin applied to a suitable surface and covered with loose aggregate. Once cured the remaining loose stones are removed. Thicknesses are governed by aggregate size. i.e. 1-3mm aggregate will have a nominal depth of 3mm.

Resin Bound (Addaset) This differs in so far as the aggregate is added to the mixed resin and further mixed. When amalgamation is complete the material is towelled down to a smooth finish similar to a screed (with no loose stones). Depths are specified depending on use, normally 15mm or 18mm.

How to specify Addastone

Typical Addastone Specification

Addastone is a two part resin surface dressing, designed to bond natural aggregates. The finish provides an attractive, safe, hard wearing, low maintenance surface for pedestrian and vehicular areas where aggregate appearance is desired.

Addastone Resin Bonded surfacing is designed to give the appearance of natural loose aggregate. A suitably sized aggregate should be chosen to give the required performance and effect. A range of aggregates is available from various aggregate suppliers. Contact Addagrip for details and advice on the suitability of the chosen aggregate.

Standard Addastone Resin colours: Buff, Natural and Black, alternative colours are available on request.

N.B. When specifying aggregates for resin bonding ensure specification is “washed and dried” do not re use aggregates or pre existing driveway gravel etc as adhesion will be compromised.

Preparation

All bituminous surfaces to be treated with ADDASTONE® RESIN should be sealed with ADDACRYL (refer to product information sheet) to prevent the resin from soaking into the capillary pores. New bituminous surfaces should be installed and compacted to current British Standard Specification.

Suggested surface course requirements are as follows:

Existing bituminous surfaces to be of sound construction: any weakness could result in a bond failure or blistering. We STRONGLY recommend that the client takes or, instructs, that core samples are taken to confirm base suitability.

Concrete and timber surfaces should be primed using EP ADDASTONE PRIMER.

Steel surfaces should be degreased and lightly shot blasted or suitably abraded prior to application of EP ADDASOL SHEILDCOAT PRIMER (refer to product information sheets).
