Resin Bound Gravel Driveway
Emerald Landscapes love surfacing work, when a customer in Cambridge was in need of some resurfacing work to their driveway, our expert team was on hand to help out.
Cambridge Project: Resin Bound Gravel Driveway
The surfacing game has really changed a lot in the past few years, aesthetically and practically combined with extra precaution on drainage has led to the rise in popularity of resin bound gravel. Its permeability, overall sleek and contemporary finish topped off with the choice in over 25 colours, makes this surfacing option a must have.
At Emerald Landscapes we are always trying to do our bit for the environment and ensuring all of the water from this driveway is sustainably drained is why we love installing a resin bound gravel driveway. The makeup of the driveway is built in 3 structural layers to form the solid foundation and SuDs ( Sustainable Drainage system ) compliant surface which does not require any additional drainage such as ACO drains or a soakaway system.
To blend in with the existing brickwork wall a resin bound gravel colour was chosen that complimented the surrounding area. We broke out and excavated the old tarmac with gravel just laid on top using a pneumatic breaker and digger, the waste was then removed by a grab lorry.
New concrete flat top edging was required at the front of the driveway due to there being a large hump where the footpath meets the drive, we levelled this out and installed the new edging ready to take the resin. The first of the structural layers was then installed on top of a Geo-textile membrane, 100mm of permeable MOT type 3 laid and compacted using a 1 ton roller.
Next was 75mm of open grade 14mm binder course of permeable tarmac, this makes up the second structural layer of the driveway. Again compacted with a 1 ton roller left 20mm off the finish height ready for the resin bound gravel. Due to the tarmac naturally having lots of oils within its compound, after this process we have to leave the surface for 10-14 days to allow all of the oils time to leach out of the surface. This is done to guarantee that when we come to lay the resin bound gravel over the top there will not be an oily layer between the 2 preventing any lifting to the finished surface.
When we returned the final structural layer was applied using aluminium trowels and smoothed out to a uniform thickness of 18-20mm. The resin bound gravel cures in around 4-6 hours so we secured the perimeter to make sure the postman did not stroll across our new driveway.
