Expansion joint sealing in Kent: how it works

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We’ll tell you if the edges need repairing before sealing and phasing can keep areas working. We work on brickwork movement joints, precast concrete panel joints and cladding panel joints, and what we’re called in for most is previous reseals laid over old sealant and water dripping through deck or ramp joints.

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you.

Photos, joint lengths and drawings come to us, or we visit.
We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
Every joint is cleared of the failed seal and any grit packed into it.
Edges are checked, and we tell you if any need repairing before sealing.
The right sealant goes in at the right depth, bonded to the two sides only.
Areas reopen once cured, and the work carries our 12-month guarantee.

Estates, car parks and floors in Kent

From Maidstone, Ashford and Canterbury to smaller places, Kent has buildings and slabs with movement joints that need resealing as they age. When they fail, water and grit get in and the edges start to break.

All of Greater London is inside the ULEZ, and much of the South East is within easy reach of the capital, so jobs in Kent are planned with access, loading and parking in mind. Coastal places in Kent often have hotels, guest houses and holiday accommodation with busy seasons, which makes the quieter months a good time for sealant work.

Maidstone: University campuses such as University for the Creative Arts (1.3 miles west of Maidstone) have car parks, paved walkways and building elevations with movement joints. At places like Powerhub Business Centre, which lies north-west of Maidstone, joints are sealed a section at a time so operations carry on.

Why deal with it now?

Closing a car park for a reseal is rarely an option. Work can be planned so parts of the deck stay open without shutting the whole car park. Tell us what has to stay open and we’ll plan around it.

General trades versus a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

When something else is needed

Not every problem is a sealant problem, and we’re upfront when that’s the case. These need a different solution:

Structural movement beyond what the joints were designed for (that needs a structural engineer)
Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

Common problems we fix in Kent

On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. A sealant that isn’t trafficable won’t last there.

If one of these sounds familiar, it’s time for a closer look:

Hardened, cracked sealant on exposed facades
Joints packed with grit and debris
Arrises breaking up along floor joints
Water dripping through deck or ramp joints

What sets the cost

Sealant work doesn’t have a standard rate, because every site is different. What we take into account:

Distance, for remote addresses
Removal of failed or old sealant
The size and state of each joint
Any access equipment needed

Pricing movement joints depends on quantities, condition and access, and any specification that applies. Ask us for a fixed quote.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

Asbestos survey details if the building is older
A wide shot and a close-up of the area
What the building is and how it’s used
The postcode of the building

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Kent: questions and answers

What guarantee do you give on joint sealing?

Each job is backed by a 12-month guarantee on the workmanship. The guarantee covers how we sealed, not damage caused afterwards.

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you offer coloured sealant?

That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What hours do you work?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.
