Expansion joint sealing for Dungate sites

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

How we handle expansion joint sealing in Dungate

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we’ll say so before sealing and phasing can keep areas working. We work on car park decks and ramps, precast concrete panel joints and brickwork movement joints, and what we are called in for most is water getting into the wall through a failed joint and torn sealant in brick or block movement joints. Looking for mastic applicators who cover Dungate? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Smaller community and commercial buildings around Dungate have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

What affects the price in Dungate

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

  • Induction, permit and paperwork requirements
  • Whether old sealant has to be cut out first
  • Any access equipment needed
  • Travel to remote or island sites

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • How the joints are reached, and at what height
  • The type of building and who uses it
  • The asbestos register, for older buildings
  • When you need the work done

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, call the office on 01277 525 020 or email the details over.

Our process

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Dungate, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Preparing the site

  • Tell staff and tenants when we’ll be in
  • Share your working hours and any access restrictions
  • Share the asbestos register for older buildings

Slabs, ramps and loading bays in Dungate

The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open. Dungate lies roughly 39 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

Parks like Kent Science Park (to the north-west of Dungate) combine paved areas, car parks and building elevations, each with joints that move. Campuses like Canterbury Christ Church University (to the south-west of Dungate) mix old and new buildings, with movement joints wherever they meet. Schools such as Milstead and Frinsted Church of England Primary School have movement joints in their walls and floors that are easy to overlook.

Dungate is about 3 miles south of Sittingbourne, in Kent. Across the ME9 postcode area, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Dungate is one of 931 places we cover in Kent for movement joints. London is covered too, some 39 miles away.

We take on movement joints across the ME9 postcode area. Sites close to Dungate are covered too, including Newbury (1 mile north-east), Kingsdown (1 mile east), Rodmersham Green (1 mile north), Highsted (1 mile north) and Bapchild (1 mile north-east).

What the job involves on each surface

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement.

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.

Doing it in-house

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

When something else is needed

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Movement on a scale no sealant is meant to absorb
  • Joints too narrow for the movement, which need redesigning by the engineer
  • Proprietary pre-formed expansion joint systems

Not sure which it is? You can ring 01277 525 020 or use the quote form and we will tell you honestly before you book.

Your questions answered

Is a hospital such as Sittingbourne Memorial Hospital somewhere you can work?

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.

Does your area include sites such as Kent Science Park, near Dungate?

Yes. Estates, retail parks and business parks around Dungate, Kent Science Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Which product is best for expansion joints?

It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane, and the specification has the final say.

How long does movement joint sealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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 do sealant joints 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.

How do we ask for a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Why deal with it now?

A torn seal left alone typically gets worse. Grit and water fill the gap and the material either side breaks up, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Converted and older buildings near places like Dungate tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
