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 should sites in Alloa consider?
Hygiene-sensitive sites in Alloa, such as food processors, can use dock seals to reduce the gaps through which dust and pests might enter during loading. Before recommending seals for a bay in Alloa, we check how consistent your trailers are, because mixed fleets are usually better served by a shelter.
Where trailers reverse onto a bay in Alloa slightly off-centre, tapered side pads and wheel guides help protect the seal from rubbing.
If you are planning dock seals for a site in Alloa, expect four stages. A free survey and fixed written quote come first. We then agree a programme with you, including any out-of-hours work. Specialist installation engineers carry out the installation under our management, with us as your single point of contact. Finally, the equipment is tested, your staff are shown how it works and everything is handed over with its 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 much do dock seals cost?
A set of dock seals typically costs £1,100 to £2,600 per set, excluding VAT, supply and fit. A set is normally a head pad and two side pads for one bay.
The price depends on:
- Pad size and depth: larger openings and deeper foam cost more.
- Head arrangement: a fixed head pad, or a curtain head for varied trailer heights.
- Cover fabric: heavier coated fabric and replaceable wear pleats last longer.
- Pad shape: tapered side pads that guide the trailer and intrude less into the opening.
- Mounting: fixing direct to masonry, to a steel frame, or to brackets that set the projection.
- Site work: removing old seals, adjusting bumpers and powered access equipment.
Where the foam is still sound, new covers can cost less than new pads, and we will say if that is an option. After a free site survey you receive a fixed written price for the work described.
The same published guide range applies across Scotland; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Control positions, isolators and any existing interlocks
- Scope to convert ground-level doors into docks or add lift tables
- Dock height and the mix of trailers you load
- Working hours, shift patterns and windows for out-of-hours work
- Forklift and pallet truck loads crossing the leveller platform
- Headroom above the opening and which track type will suit it
Options to discuss
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.
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.
What do the rules in Scotland mean for the work?
HSE is the workplace safety regulator in Scotland. At a loading bay in Alloa, doors need to satisfy regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, dock equipment must be kept safe under PUWER, and drivers must be prevented from pulling away too early. We check what applies at survey.
Questions about dock seals in Alloa
Will you deal with building control and planning for a project in Alloa?
We check at survey whether the work is likely to need approval. Forming a new opening or dock pit may need Building Regulations approval, a building warrant or building control approval, depending on the nation, and external structures such as loading houses can need planning permission. Where approval is needed, we explain what is involved, work with your designer or agent, and build it into the programme.
Do you remove and dispose of the old equipment?
Yes, where it is part of the scope. When we replace doors, levellers, shelters or seals at a site in Alloa, removal and disposal of the old equipment can be included and is itemised in the quote, so it is clear what is covered. If anything should be kept, such as a frame or motor that is still serviceable, we agree that at survey.
Do you cover Alloa for dock seals?
Yes. We take on dock seals for businesses in Alloa and across Forth Valley. We survey the site, provide a fixed written quote and manage the installation, with specialist installation engineers working under our management. Visits are arranged in advance at a time that suits your operation, and the same single contact stays with the job through to handover.
How can I tell if seal projection is wrong?
Look at the pads with a trailer docked. Daylight around the head or sides suggests too little compression, while pads squashed flat or bulging around the trailer suggest too much. Worn bumpers are a common cause, and both can be checked at a planned service.
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.
