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.
Is this right for your site in St Austell?
Before recommending seals for a bay in St Austell, we check how consistent your trailers are, because mixed fleets are usually better served by a shelter. A dedicated chilled fleet serving a site in St Austell can be sealed closely with foam pads, at lower cost than fitting an inflatable shelter.
Older seals at docks in St Austell that have been left with split covers can soak up rain, becoming heavy and losing their shape over winter.
It starts with a free site survey in St Austell, where we measure the openings, check the dock and talk through how the bay is used. You then receive a fixed written quote. Once you accept, we manage the job: specialist installation engineers carry out the work under our management, planned around your deliveries, and out-of-hours working can be arranged. At handover we test everything with you and leave the documentation.
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 England; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Headroom above the opening and which track type will suit it
- Whether planning, building control or a building warrant may be needed
- Gaps around trailers where heated or chilled air escapes
- Drainage on recessed or sloping dock approaches
- Yard gradient and the slope of the approach to the dock
- How drivers are prevented from pulling away too early
Options to discuss
Tapered side pads
Side pads tapered in section so they guide the trailer in and intrude less into the trailer opening, which extends pad and cover life.
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.
What do the rules in England mean for the work?
Sites in St Austell fall under the rules for England. Structural changes such as forming a new opening or a dock leveller pit may need Building Regulations approval, and external structures such as loading houses, canopies or new dock approaches can need planning permission from the local planning authority. We check what applies at survey and build any approvals into the plan.
Questions about dock seals in St Austell
Which building and safety rules apply to a site in St Austell?
It depends on which UK nation the site is in. England and Wales use Building Regulations approval, Scotland uses building warrants and Northern Ireland uses building control approval from the council. Workplace safety is regulated by HSE in Great Britain and HSENI in Northern Ireland, and energy rules differ between nations. For your site in St Austell, we check what applies at survey and design to it.
Can you work outside our normal operating hours in St Austell?
Yes, by arrangement. Evening, night and weekend working can be planned so the installation causes as little disruption as possible to your loading schedule. Out-of-hours work can affect the price, so mention it at the survey and we will include it in the written quote. The agreed times are confirmed in the programme before the job starts.
How do you price dock seals for a site in St Austell?
Guide budgets for supply and fit are £1,100 to £2,600 per set, excluding VAT. The figure moves with size, insulation, the operator, electrics, access, any pit or groundworks and out-of-hours working. Where levellers are involved, the guide assumes an existing, sound pit. After the free survey you receive a fixed written quote, and that is the price for the agreed scope.
Can just the covers be replaced?
Yes, if the foam is still resilient and dry, new covers can often be fitted over the existing foam, which usually costs less than new pads. Waterlogged or permanently crushed foam should be replaced. Cover replacement is handled as a repair, with the visit price agreed beforehand.
Do dock seals block access to the trailer?
They can if they are poorly sized. Side pads that sit inside the line of the trailer body intrude into the opening and get in the way of pallets and forklifts. Correctly sized and tapered pads compress against the rear corners and leave the opening clear.
