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.
How does this suit sites in Crawley?
A dedicated chilled fleet serving a site in Crawley can be sealed closely with foam pads, at lower cost than fitting an inflatable shelter. Own-fleet distribution sites in Crawley, where the same trailers arrive day after day, are well suited to foam dock seals and the tight fit they give.
Heated packing halls next to a dock in Crawley lose less warmth during loading when the gap around each trailer is closed by compressed foam.
It starts with a free site survey in Crawley, 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.
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.
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.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What does the free survey cover?
- Wind exposure at the dock, which affects door and shelter choice
- Escape routes and pedestrian doors close to the bay
- Forklift and pallet truck loads crossing the leveller platform
- Scope to convert ground-level doors into docks or add lift tables
- Asbestos register and any other site hazard information
- Access for deliveries, cranes or lifting equipment during installation
Options to discuss
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.
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.
What do the rules in England mean for the work?
Sites in Crawley 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 Crawley
Will you deal with building control and planning for a project in Crawley?
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.
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 Crawley 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.
How long does installation take at a site in Crawley?
It depends on the equipment, the number of bays, the condition of the dock and whether any building or electrical work is needed. We agree a programme with you after the survey, setting out which bays are out of use and when. Larger jobs are usually phased so that part of the dock stays open, and out-of-hours working can be arranged.
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.
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.
