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 Larne consider?
Hygiene-sensitive sites in Larne, such as food processors, can use dock seals to reduce the gaps through which dust and pests might enter during loading. Weather-exposed bays in Larne gain the most from a well-fitted seal, since wind and rain otherwise find every gap around the trailer.
Before recommending seals for a bay in Larne, we check how consistent your trailers are, because mixed fleets are usually better served by a shelter.
Any project involving dock seals at a working site in Larne takes planning. We survey free of charge, quote a fixed price in writing, and then agree a programme that keeps as much of the dock running as possible. Specialist installation engineers carry out the work under our management, out of hours if that suits you better. On completion we test each item, show your team how it operates and leave the documentation with you.
When is a dock seal a better choice than a shelter?
A dock seal is a better choice than a shelter when the trailers using a bay are consistent in size, the dock height suits them, and the tightest practical seal matters. Mixed fleets are usually better served by a shelter.
- Consistent fleets: dedicated vehicles or regular hauliers using the same trailer type.
- Temperature control: chilled or heated buildings where gaps around the trailer are costly.
- Security and hygiene: fewer gaps for pests, dust and unauthorised access during loading.
- Budget: seals cost less than inflatable shelters for a close fit.
The trade-offs are that seals can leave gaps at trailer door hinges, side pads can intrude into the trailer opening if poorly sized, and the covers wear from rubbing. If your trailers vary, compare our retractable dock shelters before deciding, as they leave the full opening clear.
What do workplace transport rules mean for a sealed dock?
A sealed dock still needs safeguards against a trailer leaving early, and the seal, bumpers and other dock equipment must be kept in safe working order. In Great Britain the regulator is HSE; in Northern Ireland it is HSENI.
- Drive-away: HSE workplace transport guidance (HSG136) and the HSE loading factsheet call for safeguards against drivers driving away too early, including traffic lights, vehicle or trailer restraints, or the person in charge keeping keys or paperwork until it is safe.
- Trailer creep: because the trailer is pressed into compressed foam, it can ease forward during forklift loading. Restraints and well-set bumpers help keep it in position.
- Equipment duties: a dock seal forms part of the loading bay's work equipment, so the general duty under PUWER 1998 in Great Britain, or PUWER (Northern Ireland) 1999, to keep equipment suitable and maintained applies.
Torn covers and crushed pads can hide damage to the fixings and wall behind, so seals belong in planned inspections of the dock.
The same published guide range applies across Northern Ireland; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Dock height and the mix of trailers you load
- Wheel guide positions and yard markings for reversing vehicles
- Gaps around trailers where heated or chilled air escapes
- Drainage on recessed or sloping dock approaches
- Wall and steel structure for door, shelter and bumper fixings
- How often each door cycles during a typical shift
Options to discuss
Fixed head pad seal
A head pad and two side pads of set depth, the simplest and tightest arrangement where every trailer using the bay is the same height.
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.
Planning, building control and safety law in Northern Ireland
Energy requirements for non-dwellings in Northern Ireland are set by Technical Booklet F2. For new or replacement loading bay doors in Larne, we confirm the figure that applies to your project and check what applies at survey, rather than working to rules from elsewhere in the UK.
Questions about dock seals in Larne
How do you price dock seals for a site in Larne?
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.
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 County Antrim 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 Larne 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.
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.
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.
