What Welwyn Garden City sites use shallow-mount bollards for
Around Welwyn Garden City, shallow-mount bollards usually solve one of these:
- Retrofits outside occupied buildings with tight programmes
- Lines that must cross over shallow drainage or ducts
- Bridges and structures where excavation depth is limited
Before we dig in Welwyn Garden City
Hertfordshire County Council is the highway authority covering Welwyn Garden City's local roads. If any post would stand on adopted highway rather than your land, that consent is the first thing we sort out.
Bollards on private land often don't need planning permission, but it depends on the council's view, the height and the location; in a conservation area, next to a listed building or under an Article 4 direction, ask the local planning authority (the council for Welwyn Hatfield) first — we flag this at survey.
Utility owners may set minimum separation distances or ask to be present when digging near their apparatus. Paving is often natural stone in the streets where these systems are used, so careful lifting, storage and relaying is part of the job.
- Get written confirmation from a structural engineer before installing on slabs, decks, basements or over voids.
- Check gaps work for wheelchair users and buggies while still stopping vehicles, referring to Inclusive Mobility guidance.
Installation, step by step
Cut and excavate the trench
Paving is lifted and kept for reuse where possible, and a shallow trench is excavated by hand near known services. Where a service sits higher than expected, work stops and the detail is referred back.
Assemble and level the frame
Frame sections are placed, joined and set to line and level, with posts fixed as the drawing shows. Joints and fixings are photographed before any concrete goes in.
Pour, cure and reinstate
Concrete is placed to the specified grade and finish depth, then the surface is rebuilt to match. The line is protected until the specified curing period has passed.
Finishes and options
| Option | Detail |
|---|---|
| Surface-mounted rated units | Some tested products sit on or very close to the surface with minimal digging. These are often used for temporary or semi-permanent protection and need careful checking of the surface they bear on. |
| Covers and sleeves | Stainless, cast or powder-coated covers fitted over the cores to match surrounding street furniture, supplied or approved by the manufacturer. |
| Rated planters and street furniture | Benches, planters and cycle stands built around a tested shallow core, used where a line of posts would look out of place. |
Pricing shallow-mount bollards in Welwyn Garden City
Two Welwyn Garden City jobs with the same number of posts can price quite differently. The usual reasons:
- Changes of direction, end details and removable positions
- Restricted working hours in busy streets or occupied sites
- Amount of hand digging needed around live services
Keeping them working
Once cured, a shallow-mount line needs much the same care as any static rated barrier: periodic visual checks, cleaning of covers and renewal of visibility bands. Any later utility work beside the line should be supervised so the frame is not undermined.
For damaged or loose posts in Welwyn Garden City, repairs and replacements are priced in writing first.

Will future roadworks damage the system?
They can if contractors dig beside it without knowing it is there. That is why we provide as-built drawings showing the frame position. Ask anyone excavating nearby to check those drawings first.
Can I install a single shallow-mount bollard on its own?
Usually not. Most shallow systems rely on several posts working together, and the rating applies to a tested run with a stated minimum number of posts. A single position generally needs a different solution.
