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.
What matters for dock seals in Gorseinon?
Where trailers reverse onto a bay in Gorseinon slightly off-centre, tapered side pads and wheel guides help protect the seal from rubbing. Before recommending seals for a bay in Gorseinon, we check how consistent your trailers are, because mixed fleets are usually better served by a shelter.
Own-fleet distribution sites in Gorseinon, where the same trailers arrive day after day, are well suited to foam dock seals and the tight fit they give.
Keeping the dock running is usually the first concern, so we plan around it. After a free survey of your Gorseinon site and a written quote at a fixed price, we agree when each bay can be released and whether any work should happen out of hours. Specialist installation engineers working under our management then fit the equipment, and we test it and hand over the documentation before the bay goes back into use.
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.
The same published guide range applies across Wales; access, out-of-hours working and site conditions are confirmed at the free survey.
Survey checklist for your dock
- Asbestos register and any other site hazard information
- Bumper position and wear or damage on the dock face
- How often each door cycles during a typical shift
- Headroom above the opening and which track type will suit it
- Condition of any existing leveller pit, kerb angles and pit drainage
- Power supply at each bay, including three-phase availability
Options to discuss
Replaceable wear pleats
Sacrificial fabric strips on the pad faces that take the rubbing from trailers and can be replaced without changing the whole cover.
Seal with curtain head
Foam side pads combined with a flexible top curtain that adjusts to trailers of different heights, a halfway point between a seal and a shelter.
Regulations and approvals in Wales
Sites in Gorseinon follow the rules for Wales. Forming a new opening or dock pit may need Building Regulations approval, and loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey, so any approvals are understood before the programme is fixed.
Questions about dock seals in Gorseinon
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 West 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.
Is the site survey in Gorseinon free?
Yes. For new installations, replacements, upgrades, conversions and complete bays, the site survey and written quote are free and come with no obligation. The survey lets us measure the openings, check the dock and structure, and understand how the bay is used, so the quote reflects your site. Repair and servicing visits are different: they are chargeable, with the price agreed before anyone attends.
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 Gorseinon 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.
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.
