Expansion joint sealing for Tonge sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Site staff or a sealant specialist?

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

About our expansion joint sealing in Tonge

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. 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. Most enquiries involve torn sealant in brick or block movement joints and hardened, cracked sealant on exposed facades, across podiums and floor movement joints, blockwork control joints and cladding panel joints. One point of contact handles commercial sealant work in Tonge from the first photographs to the final walk-round, for single jobs and planned programmes alike.

For a site near Tonge, measurements and photographs up front mean one trip where possible. Tell us the joint widths if you can, and what drives or walks over them.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Questions we’re asked in Tonge

Does the sea air around Tonge change the choice of sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. We check the specified product suits the exposure and pay close attention to preparation.

Do you take on work at healthcare sites like Sittingbourne Memorial Hospital?

Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.

Do you reseal car park expansion joints?

Yes. Let us know the opening hours and which levels or bays have to stay available, and we will plan the phasing around it.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Looking after the joints

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Clear dirt from joint lines during routine cleaning
  • Treat a small split as a warning, not a cosmetic issue
  • Keep traffic off new joints until the cure time is up
  • Put movement joints on the planned maintenance inspection round

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file.

When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one. We can suggest an order, worst joints first.

Surface by surface

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing and flag any joint that seems undersized.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond, so the new seal holds.

Expansion joint sealing around Tonge: how the place shapes the job

The sea is no more than about 1 mile from Tonge. Coastal yards and decks give their joints salt and wet weather to deal with, not just wheels, so it pays to keep them sealed. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Large sites such as Sittingbourne Memorial Hospital, 2.3 miles to the south-west of Tonge, have car parks, service roads and long elevations with movement joints in brick and panels. For a school such as Sittingbourne Community College, playground and building joints can be done in the holidays.

Tonge is about 2 miles east of Sittingbourne, in Kent. If you are looking for expansion joint sealing in Tonge, we can help. Tonge is one of 931 places in Kent on our list. There’s a separate page for London, about 39 miles away.

When something else is needed

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • A joint that has to be widened or re-detailed before it can work
  • Proprietary pre-formed expansion joint systems
  • Concrete or masonry repairs along the arrises

Not sure which it is? You can ring 01277 525 020 or send photos by email and we will tell you honestly before you book.

What we seal

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

Cost factors for movement joints

Your fixed quote is built from the real scope. It allows for:

  • Distance, for remote addresses
  • Any access equipment needed
  • How much existing material needs removing
  • Site requirements such as inductions and permits

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Anything awkward about access or site hours
  • Whether the building will be occupied during the work
  • Clear photos of the problem areas
  • Rough lengths or quantities, or drawings if you have them

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or email us.

From enquiry to sign-off

When we get to site, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases. For work around Tonge, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. 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.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Arrange parking or a loading space
  • Have the specification and drawings to hand
  • Warn occupants and staff about the work
