Resin Bound Gravel Hospital Gardens

Summit Landscapes resurfaced three internal gardens within the grounds of Cambridge’s Ida Darwin Hospital. Our client (the NHS) wanted resin bound gravel for the surfacing as there are no loose stones to repeatedly sweep up and it creates a clean, contemporary feel.

Summit Landscapes cut down and removed a tree from one of the gardens and laid suitable sub-bases, installed metal edging around each resin bound gravel surface. The first garden was 91m², the second was 63m² and the third was 84m².

Garden 1: Paved Area

Resin Bound Gravel 91m²
– Excavated area using a digger to a depth of 200mm and removed waste from site
– Laid geotextile weed membrane over the area to suppress weed growth
– Laid 50mm compacted limestone
– Laid 50mm base coat (SMA) porous Tarmac so Aco drains will not be required
– The resin was mixed precisely with an activator
– The resin and gravel were combined using a forced action mixer
– Resin bound mixture was then spread and regulated over the area
– Edging was installed 300mm from the building and gravel spread 5m²
– Reinstalled raised flower beds at the end of the project
– Installed new sleeper beds
