Harlow, Essex -- A project to build a designer home on the site of some old farm buildings in a new UK National Park is using a polyurethane-bound aggregate surfacing on the groundworks of the three-acre site.
The blend of naturally coloured aggregates was selected as in keeping with the house surroundings. The light shade of the aggregate will not change over time because the elastic polyurethane resin does not degrade when exposed to ultraviolet light, says Ronacrete, supplier of the resin surfacing.
The owner employed BPR Architects to design Downley House as a family home, on the site of old farm buildings within the newly formed South Downs National Park. Part of the original house remains as a folly next to the main house. The building's two wings are linked by a barrel-vaulted dining hall. Other features are a copper roof and glass surround spiral staircase leading to a roof terrace.
PRC Landscapes did the groundworks and landscaping, including application of the RonaDeck Resin Bound Surfacing from Ronacrete, a Harlow, Essex-based surfacing supplier.
The two-part aggregate system, which is compliant with SuDS (sustainable drainage systems) was applied to 650 square metres of macadam substrate including patios, the driveway and turning circle.
The resin is supplied in two components which were mixed with a drill and paddle before being added to the aggregate blend. The complete surfacing system was mixed in a high-capacity forced action mixer and poured, spread to level and trowel-finished at a thickness of 15mm. The paving was ready for foot traffic in four hours and ready for vehicles after 1-2 days.
