The Challenge



To provide a robust paved surface for both vehicular and pedestrian use to;

Soften the impact of the building

Provide a welcoming area for pedestrian use


The paved surface would have to;

Accommodate vehicular traffic in areas.

Be porous in areas, to comply with planning permission.

Provide pedestrian crossings and disabled parking without the use of painted road markings.

Provide kerbing, manhole covers and tactile flags.

Accommodate the use of steel bollards to segregate pedestrian walkways.

Accommodate soft landscaping features.

The Solution

Roadstone provided 3000m2 of 80mm Castlestone Paving for the vehicular trafficked area. This paving was natural in colour with the zebra pedestrian crossings, created using natural and charcoal bands, and disabled parking being delineated by charcoal coloured Castlestone Paving Bricks.

The porous area was paved using 800m2 of Aqua Cobblesett 80mm Permeable Paving which was natural in colour to compliment the trafficked area (ground investigations were carried out by Michael Punch and Partners Engineering).

Buff tactile flags were used at the pedestrian crossings.

Castlestone kerbs were used on edge at the grass verges.

Recessed steel manhole covers were employed to allow for the paving of manhole covers.

The Result

Roadstone provided a naturally coloured multifunctional paved surface which both softened the impact of the adjacent buildings and provided a welcoming area for both students and members of the public.


What we Learned –

Use Aqua Castlestone 60mm in Pedestrian Porous areas to tie in with main Castlestone paving (Not available at the time of construction but now available).

Ensure Roadstone’s Aquaflow Permeable Paving build up stone is used as specified.
