Expansion joint sealing for businesses in Saltwood

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing in Saltwood

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. If you have previous reseals laid over old sealant and water dripping through deck or ramp joints, we can put it right, on car park decks and ramps, brickwork movement joints and cladding panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Saltwood, preparation and product choice get the time they need.

In and around smaller places like Saltwood, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

How a job runs

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Saltwood are normally planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Getting the site ready

  • Tell staff and tenants when we’ll be in
  • Agree which areas must stay open
  • Let us know about inductions and permits

Common problems we fix in Saltwood

Repeated failure often traces back to the wrong product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600, and specifications often refer to it.

Most enquiries start with something like this:

  • Expansion joints filled with dirt and stones
  • Water getting into the wall through a failed joint
  • Chipped joint edges on forklift routes
  • Expansion joints split through the centre of the bead

For estates staff at a university like University Centre Folkestone, which lies east of Saltwood, building and paving joints are part of the planned maintenance list.

What your quote should include

  • Will RAMS and insurance details be available?
  • Whether primer will be used where the manufacturer specifies it
  • How joint depth will be controlled
  • What level of public liability insurance do they hold?

How to choose a sealant contractor

Different surfaces, different methods

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. We use a sealant made for wheel loads and the expected movement.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them.

When it isn’t the sealant

Being straight saves everyone time. Fresh joints won’t solve:

  • 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)
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

If you are not sure, just call the office on 01277 525 020 or email the details over and we will give you a straight answer.

Where we work in Saltwood

  • Podiums and floor movement joints
  • Car park decks and ramps
  • Cladding panel joints
  • Blockwork control joints
  • Precast concrete panel joints
  • Brickwork movement joints

Doing it in-house

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.

Warehouse floors and decks around Saltwood

Saltwood is within about 1 mile of the coast. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, which is why split joints are worth sealing before the edges deteriorate. Saltwood lies roughly 58 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London.

Large sites such as Royal Victoria Hospital, 4.1 miles to the east of Saltwood, have car parks, service roads and long elevations with movement joints in brick and panels. Schools such as Saltwood CofE Primary School have movement joints in their walls and floors that are easy to overlook.

What affects the price in Saltwood

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Induction, permit and paperwork requirements
  • Distance, for remote addresses
  • How accessible the joints are
  • Specialist products, such as fire-rated or hygienic sealants

The price depends on the quantity of joints, how much old material needs removing and how the joints are reached. Call for a quote when you’re ready.

What to include in your enquiry

Whether it’s one area or a whole building, these details speed things up:

  • Access details, including height
  • Your programme or deadline
  • The product your specification calls for
  • The postcode of the building

For a fixed quote, call the office on 01277 525 020 or send details through our quote form. You can also send details through our quote form.

Saltwood: questions and answers

Can you work at a site such as Shorncliffe Industrial Estate, by Saltwood?

Yes. We cover Saltwood and the area around it, including industrial estates, business parks and retail parks such as Shorncliffe Industrial Estate. To start, just call 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

Can being near the sea in Saltwood affect the sealant we need?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Do the joint edges need to be sound before sealing?

Sealant needs sound faces to bond to, so we’ll tell you if the edges need repairing before sealing. Where it’s visible beforehand, we’ll say so when we quote.

How long will the new sealant last?

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

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
