A dock seal is a set of fabric-covered foam pads fixed to the building around a loading bay door, usually a head pad and two side pads. When a trailer reverses in, its rear end presses into the foam, which compresses to close the gaps around the trailer body. Seals give a very tight fit but work best when the trailers using the bay are a consistent size.
Why do sites in Mid Glamorgan choose this?
Weather-exposed bays in Mid Glamorgan gain the most from a well-fitted seal, since wind and rain otherwise find every gap around the trailer. Where trailers reverse onto a bay in Mid Glamorgan slightly off-centre, tapered side pads and wheel guides help protect the seal from rubbing.
Older seals at docks in Mid Glamorgan that have been left with split covers can soak up rain, becoming heavy and losing their shape over winter.
Our part of the job in Mid Glamorgan is to survey, quote and manage; the fitting itself is done by specialist installation engineers working under our management. The survey and the written quote are free. Once the fixed price is accepted, we agree dates that work around your deliveries and shifts, including out-of-hours working where needed. Every installation is tested before handover, and you receive the documentation for each item fitted.
Why does the gap between the seal and the bumpers matter?
The distance between the face of the seal and the face of the bumpers decides how far the trailer compresses the foam, and getting it right is the difference between a good seal and pads that are crushed or leave gaps.
- Too little projection: the trailer meets the bumpers before it presses the foam enough, leaving gaps at the head and sides.
- Too much projection: the foam is over-compressed, which crushes the pads, strains the fixings and can push the trailer forward as the foam recovers.
- Worn bumpers: let trailers travel further than designed, over-compressing the seal every time.
Correct projection depends on the foam depth and your trailers, so we set it at installation and it should be checked at each service. Keeping dock bumpers in good condition protects both the seal and the leveller from repeated impact.
How are dock seals fitted to a loading bay?
Dock seals are fixed to the outside wall around the dock door, normally on brackets or a frame that sets their projection, and a set usually takes a few hours to fit. No power supply is needed.
- The wall is checked for sound fixing points, with a frame or spreader plates added on cladding.
- The head pad and side pads are positioned to suit your trailer width and height.
- Projection is set relative to the bumpers, so trailers compress the foam by the right amount.
- Bumpers are checked and, if worn, replaced at the same time.
- A trailer is docked to confirm an even seal along the head and sides.
From you we need the bay taken out of use, a clear area in the yard for powered access equipment and, ideally, one of your usual trailers available at the end of the job so the fit can be checked under real conditions.

What do the rules in Wales mean for the work?
HSE regulates workplace safety in Wales. Loading bays in Mid Glamorgan need doors that meet regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, work equipment maintained under PUWER, and safeguards that stop vehicles leaving the dock too early. We check what applies at survey and build those measures into the design.
Questions
What warranty comes with new loading bay equipment?
New equipment comes with the manufacturer's warranty, which varies by product. Our workmanship terms are set out in writing in the quote for your Mid Glamorgan site, so you can see what is covered before you commit. Check the warranty terms for any servicing conditions, and we can quote for planned maintenance once the installation is complete.
Is VAT included in your guide prices for dock seals?
No. Our customers are businesses, so guide prices exclude VAT, which is added at the standard rate. The same guide range applies in Mid Glamorgan as everywhere else: for dock seals, it is £1,100 to £2,600 per set, excluding VAT. It covers supply and fit for a typical installation. Your fixed written quote after the free survey shows the net price, the VAT and exactly what is included.
Do trailer doors need to be opened before docking against a seal?
Yes, the rear doors are opened and folded back before the trailer reverses onto a seal, so the pads press against the rear of the trailer rather than the doors. Gaps can remain at the door hinges, which is a known limitation of seals compared with shelters.
Are dock seals suitable for cold stores?
Yes, for cold stores with consistent trailers a dock seal gives a tight fit at a lower cost than an inflatable shelter. The pads must be kept in good condition, because water in the foam can freeze and stiffen it. Mixed fleets at cold stores are often better served by inflatable shelters.
