Permissions and groundwork in Caernarfon
In Caernarfon the highway authority for local roads is Gwynedd Council. We confirm whether the ground is adopted highway before quoting, because shallow-mount bollards on a public footway need its agreement first.
Many private-land installations in Caernarfon 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 Gwynedd Council before posts go in.
Shallow does not mean simple. The trench has to sit over services with enough cover to protect them, but the frame also needs a firm, consistent bearing; soft spots, old backfill around pipe trenches and voids under paving can all need treating first.
- Agree works and separation distances with utility owners, and with the highway authority where the line is on public highway.
- Check gaps work for wheelchair users and buggies while still stopping vehicles, referring to Inclusive Mobility guidance.
How the job runs
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.
Specification choices
| Option | Detail |
|---|---|
| Removable posts within a run | Some systems include removable or retractable positions for maintenance or emergency access. Check how these affect the rating. |
| 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. |
Pricing shallow-mount bollards in Caernarfon
Two Caernarfon jobs with the same number of posts can price quite differently. The usual reasons:
- Restricted working hours in busy streets or occupied sites
- Changes of direction, end details and removable positions
- Structural engineering checks on slabs or decks
After installation
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. Pay attention to the surface around the posts, because settlement or loose paving can indicate movement in the bearing layer.
We can also service, repair or replace existing posts anywhere in Caernarfon.

Does a shallow system protect as well as a deep one?
It can achieve the same rating, because both are tested to the same standards. What differs is how the load is resisted. Your security adviser should compare the specific ratings, not the foundation depths.
What if a service turns out to be higher than the records show?
Work stops at that position and the finding goes back to the manufacturer and your adviser. Sometimes the frame can be adjusted within tested limits; sometimes the utility has to be lowered or the line moved. We do not improvise a change to a rated foundation on site.
