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.
Why do sites in Erith choose this?
Before recommending seals for a bay in Erith, we check how consistent your trailers are, because mixed fleets are usually better served by a shelter. Hygiene-sensitive sites in Erith, such as food processors, can use dock seals to reduce the gaps through which dust and pests might enter during loading.
Heated packing halls next to a dock in Erith lose less warmth during loading when the gap around each trailer is closed by compressed foam.
Before anything is ordered, we visit your site in Erith for a free survey and then send a written quote with a fixed price. From that point we manage the installation, coordinating delivery, access and any other trades. Fitting is done by specialist installation engineers engaged and managed by us, at times that suit your operation, including out of hours where agreed. You get a tested installation, a demonstration for your team and the manufacturer 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.
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.
The same published guide range applies across England; access, out-of-hours working and site conditions are confirmed at the free survey.
What do we check at the survey?
- Escape routes and pedestrian doors close to the bay
- Asbestos register and any other site hazard information
- Yard gradient and the slope of the approach to the dock
- How drivers are prevented from pulling away too early
- Access for deliveries, cranes or lifting equipment during installation
- Forklift and pallet truck loads crossing the leveller platform
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.
Tapered side pads
Side pads tapered in section so they guide the trailer in and intrude less into the trailer opening, which extends pad and cover life.
Planning, building control and safety law in England
Workplace safety in England is regulated by HSE. For a loading bay in Erith, that means doors meeting regulation 18 of the Workplace (Health, Safety and Welfare) Regulations 1992, equipment maintained under PUWER and suitable safeguards against vehicles driving away too early. We check what applies at survey and design the bay accordingly.
Questions about dock seals in Erith
Can you work outside our normal operating hours in Erith?
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.
How do you price dock seals for a site in Erith?
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 the site survey in Erith 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.
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.
