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 Coleraine?
Before recommending seals for a bay in Coleraine, we check how consistent your trailers are, because mixed fleets are usually better served by a shelter. Older seals at docks in Coleraine that have been left with split covers can soak up rain, becoming heavy and losing their shape over winter.
A dedicated chilled fleet serving a site in Coleraine can be sealed closely with foam pads, at lower cost than fitting an inflatable shelter.
Your loading bay stays our responsibility from the survey to the handover. In Coleraine, the survey and written quote are free, and the quoted price is fixed for the agreed scope. Installation is carried out by specialist engineers working under our management, at times planned with you to protect your loading schedule. Out-of-hours work is available by arrangement. We finish by testing the equipment and handing over its documentation.
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.
How can dock seal pads be made to last longer?
Dock seal pads last longer when trailers arrive straight and stop at the right point, because most wear comes from trailers rubbing against the covers or pressing too far into the foam. Covers usually wear first, and the foam inside can outlast them.
- Replaceable wear pleats: sacrificial strips on the pad faces take the abrasion and can be swapped cheaply.
- Wheel guides and dock lights: help drivers reverse squarely into the centre of the bay.
- Bumper maintenance: keeps compression within design limits.
- Tapered side pads: guide trailers in and reduce rubbing on the pad edges.
- Driver briefings: regular hauliers who know the bay damage it less.
When covers split, replacing them promptly stops rain soaking into the foam, which makes it heavy, slow to recover and prone to freezing in winter.
The same published guide range applies across Northern Ireland; access, out-of-hours working and site conditions are confirmed at the free survey.

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.
Regulations and approvals 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 Coleraine, 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 Coleraine
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 Coleraine 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 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 Coleraine, 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.
Is the site survey in Coleraine 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.
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.
Can dock seals handle trailers of different heights?
Only within a limited range. A fixed head pad seals well on trailers of one height but leaves gaps over lower ones and can be crushed by taller ones. A seal with a flexible curtain head copes better with varied heights, and for very mixed fleets a shelter is usually the better option.
