Product: Resin Bound Paving
Supplier: Making Ground
Resin Bound Permeable
A single layered material that is hand applied and trowelled to a smooth finish. Resin bound aggregate paving is permeable, allowing water to permeate through the surface.
The system needs to be mixed on site and cold applied, using high quality clear resin bind to coat the aggregate particles prior to laying.
We have tested all of our approved stone mixes for strength and UV resistance. If customers wish to use other stone mixes, they need to ensure that they are fit for purpose. Please contact the company for further details.
Product included in this system
Resin Bound materials are supplied in pre-weighed kits. Each kit comprises of two basic elements:
- The Resin Binder (which comes in 2 components – Part A and Part B).
- And Pre-weighed aggregate mix.
Note: If installing onto a concrete base you will also need to consider our Concrete Primer.
The figures below are typical properties achieved in laboratory tests at 21°C and 55% Relative Humidity.
Resistant to temperatures of up to 50°C for long periods.
To various acids, diesel and petrol as well as strong bases.

Speed of Cure
Resin Bound involves mixing the polyurethane resin binder directly with the aggregate blends, in a forced action pan mixer. Once mixed thoroughly, it is then applied to the substrate and hand-trowelled to a smooth finish, at the intended thickness.
The typical depth of Resin Bound Paving surface, based on applying onto a sound and stable substrate, such as asphalt or concrete:
A. 18 mm depth for pedestrian traffic.
B. 25 mm depth for vehicular traffic.
*Thickness: Minimum x3 the largest aggregate.
The system is generally installed on a stable substrate such as concrete or asphalt and the substrate should ultimately be fit for the intended purpose (e.g. pedestrian or vehicular traffic). The substrate structure must be adequate to support the traffic without undue cracking or deformation during the life of the System.
Ensure the substrate is clean, dry, and fully cured prior to the installation of the Resin Bound System. The area should also be free from laitance and any contamination that may impair the adhesion of the system.
All imperfections in the substrate should be rectified prior to laying the resin bonded system. Any surface irregularities should be removed by suitable methods, such as shot-blasting or by grinding. Any loose surface pieces or cracks must be repaired with a suitable repair product.
Edging and Joints
Perimeter Edging – A perimeter edging should be installed to contain the resin bound surface. An Edging / Termination detail such as a metal profile / kerb / natural stone banding / wall / etc.) can be used.
Expansion Joints – Any Movement / Construction joints in the substrate should be extended to the surface, through the Resin Bound System.
Day joints – With large areas you may need to consider day joints, this is if it is unlikely to finish the application of the Resin Bound system in one day/shift. Formed day-work joints can be achieved by either a simple butt joint or a neat decorative feature of metal edging.
The installation should be carried out by an experienced contractor, details of contractors in your area can be obtained by contacting the company.

System Parameters During Application
Recommended Air Temperature: 10°C-35°C.
Recommended Ground Temperature: 10°C-35°C.
Relative Humidity: RH 30- 85%.
Dew Point: Surface temperature at least 3°C above dew point.
Moisture (No water) – Please note any moisture/water (including but not limited to – rising damp from the substrate / damp from adjacent fixings e.g. mortar from edging / irrigation / weather, etc.) must be avoided, otherwise it may affect the performance and even cause foaming of the PU binders.
Weather Limitations – Check weather forecasts in advance, it is vital that the Resin Bound system is not exposed to rain, hail, wind, debris or very hot or humid conditions during the placing/curing process.
Proceed with installation only when existing and forecasted weather conditions permit Resin Bound surface system installation to be performed according to manufacturers’ recommendations.
Mixing – Every Resin Bound mix (Resin Binder + Aggregate) should be mixed consistently and for an equal amount of time to avoid colour change from one mix to another. Do not leave mixes in the forced action mixer for different amount of times.
Resin – We recommend that all materials are stored according to the relevant Data sheets / Literature. Typically out of direct sunlight in a temperature controlled environment.
Aggregates – With regards to the aggregates we would like to highlight that they are kiln-dried aggregates which must be kept dry. The contractor must not rely on the packaging to prevent moisture ingress. Kiln-dried aggregate which becomes damp must not be used.
Clean as required, the surface should be swept regularly to keep it free of organic material such as leaves.
Detailed Maintenance Guide is available on request.
The finished system is assessed as non-hazardous to health and the environment. The long service life and seamless surface reduce the need for repairs, maintenance and cleaning. Environmental and health considerations are controlled during manufacture of the products.
To ensure you are specifying a fit for purpose surface for your project, please consult our Sales Manager for your area.
