Formpave Aquaflow at Stourhead estate

Over 1,000m2 of Formpave’s EcoGranite Aquasett paving has been used by the National Trust at its historic Stourhead estate to alleviate the risk of flooding in the large visitor reception area.

The National Trust’s Stourhead estate is a Palladian mansion set within 2,650-acres of parkland in Wiltshire. The partially-bound gravel surface at the large visitor reception area presented problems throughout the year including flooding, which was causing the existing gravel and topsoil surface to be washed away, exposing raised tree roots and creating potential trip hazards. A hard surfacing solution that was self-draining, accessible and aesthetically pleasing was needed.

Formpave combined the environmental credentials of its EcoGranite paver, containing up to 77 per cent recycled content, with the benefits of the SUDS and permeable paving system, Aquaflow.

The paving was installed in the visitor reception area, as well as the courtyard of the Spread Eagle Inn – an 18th century inn located in the village of Stourton, part of the Stourhead estate.

The visitor reception area had a number of sloping parts which meant that during heavy rainfall pools would form. Fortunately ground conditions were good, allowing Formpave to design the system to infiltrate back into the ground.

By designing and installing the system in this way, Formpave was able to manage and eradicate flooding and pooling across the entire surface.

Following the success of the first installation, the team turned its attention to the courtyard of the Spread Eagle Inn where it faced the same on-site challenges as well as a number of well-established trees.

Trees have a ‘no-dig’ zone to protect the root ball. The scheme was designed leaving a circle of exposed earth around the base of each tree.

It was important that the EcoGranite edging was seamless to the original 18th century cobbles and the paving was selected in ‘Victoria’, a warm, rustic cream colour ideal for the chalky tones of the downs.
