Consents, ground and services in Thornhill
Local roads and pavements in Thornhill are the responsibility of Cardiff Council as highway authority, with the Welsh Government's trunk road agents handling trunk roads. Posts on the public highway need that authority's consent; private land does not.
Many private-land installations in Thornhill need no planning application, but the rules don't clearly cover bollards, so listed buildings, conservation areas and prominent frontages are worth raising with the planning team at Cardiff Council before posts go in.
Each post sits on a concrete base on firm ground, and on soft verges or made ground the base is deepened or widened to suit. Because concrete bollards are heavy, a weak foundation shows itself quickly as a tilt.
- Plan lifts with an exclusion zone and suitable lifting equipment, and record the method for the site.
- Do not present untested concrete bollards as crash-rated protection.
From survey to handover
Plan lifting
Each bollard's weight is checked, and a lifting method is chosen, such as a vacuum lifter or crane arm, with an exclusion zone set during lifts.
Excavate and cast foundations
Small foundations are excavated, checked for services and cast with a dowel hole or sleeve at the right position and level.
Set the bollards
Each bollard is lowered onto a mortar bed with its dowel grouted in, checked plumb and aligned with its neighbours.
Choosing the right spec
| Option | Detail |
|---|---|
| Planters and blocks | Concrete planters and seating blocks used in place of bollards where a softer look is wanted. |
| Dowel-fixed or root-set | Dowels grouted into a foundation for most installations; root-set posts buried in the ground on softer sites. |
| Reconstituted stone | Crushed natural stone in a concrete mix, giving a Portland, buff or granite-like appearance for civic and heritage settings. |
