The following example of
resin bonded gravel was carried out to demonstrate the ease of application
and the aesthetic properties that are produced using this easy to apply
system.
A materials list is provided at the bottom of this page. |
| The area was first brushed to get rid of
any loose debris, then marked out using string lines, the plastic formed
angle bead was attached using STEVENS own brand glassfibre bridging compound
onto the primed (using G-fix primer) lines, alternatively masonry nails or
screws could have been used, in many applications these wouldn't be required
as edging bricks etc usually form the perimeter. |
 |
Gravel bonded resin can be
used in many types of applications including: Footpaths, Driveways,
Tree-pits, Cycle paths, Roads, Patios, Pool surrounds, etc.
Can be applied to many surfaces including: Concrete, Asphalt, Wood,
Compacted MOT stone, etc.
Benefits include: Low-Maintenance, Non-Slip, Wheelchair & Pushchair
friendly, Logo incorporation, Easy clean, Long lasting, Very hardwearing,
Very attractive aesthetically, etc. |
| The lettering was constructed from the
plastic angle, however this could be substituted using plywood/MDF blanks in
which case they would remain in the structure until the surrounding gravel
had cured (24 hours) they can then be removed and contrasting colour gravel
applied. |
 |
Prime area first and allow
to become tacky, approx 30 minutes. Using a Bell type mixer introduce
75 kilos of gravel then pour in 4.5 kilos of thoroughly blended G-fix
resin/hardener mix. When the gravel is fully wetted out distribute in
the area and trowel down to achieve the flat surface, white spirit can be
used to stop gravel sticking to the trowel.
NOTE: Ratio of resin mix to gravel indicated is around 6% by weight which
normally allows full and complete wetting out. However, due to the
variation in porosity of some gravels it is recommended a trial area be
tested to determine quantities required. |

The total area covered is 7m x 6m (42mē) x 15mm
thick. We did actually use 3 bags (75kg) gravel more than anticipated due
to undulations in the concrete surface.
Materials:
70m 15x15 plastic angle bead.
2 x No7 Bridger Compound.
2 x 5ltr G-Fix primer.
45 x 25kg bags 2-5mm gravel
1 x 37.5 kilo G-Fix kit for the mixes and 10 kilos approx for the top
layer seal-coat.
NOTE: on resin rich surfaces i.e. small pea gravel, silver sand or similar
can be scattered sparingly to achieve a non slip texture.
Because the area is subject to vehicular traffic a sealing layer of resin
(which increases strength) is applied to the cured surface at a rate of
approx 1 litre per 4mē.
The primer layer (polyurethane) is recommended an all concrete, wood or
metal surfaces, however it is replaced by resin on asphalt/tarmac etc.
