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 Clwyd?
Before recommending seals for a bay in Clwyd, we check how consistent your trailers are, because mixed fleets are usually better served by a shelter. Heated packing halls next to a dock in Clwyd lose less warmth during loading when the gap around each trailer is closed by compressed foam.
A dedicated chilled fleet serving a site in Clwyd 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 Clwyd, 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.
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.

Questions
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 Clwyd 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.
Can you work outside our normal operating hours in Clwyd?
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.
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.
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.
