Expansion joint sealing across Teston

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

When it isn’t the sealant

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

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • A joint that has to be widened or re-detailed before it can work
  • Proprietary pre-formed expansion joint systems

If in doubt, speak to us on 01277 525 020 or email a schedule or drawings and we will say what we think before you book.

Joints and surfaces we work on

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

Expansion joint sealing in Teston

Long runs of brick or block have movement joints built in, and they’re easy to miss until the sealant fails. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. We work on brickwork movement joints, precast concrete panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are car park joints leaking onto vehicles below and debris jammed in movement joints. Most enquiries from Teston start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Teston, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

The 12-month guarantee covers our workmanship: 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.

On site: what to expect

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Teston are normally planned as a single visit, so we ask for photos and rough sizes first. 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. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Explain the parking and delivery arrangements
  • Share your working hours and any access restrictions
  • Move anything stored against the joints

Aftercare for building managers

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Keep scrapers and ploughs from dragging across joint sealant
  • Plan racking layouts so feet don’t land on a joint
  • Leave barriers in place until fresh joint sealant has cured
  • Inspect movement joints alongside other routine building checks

On car parks, winter clearance can damage deck joint sealant. Raising blades over joints where possible protects the seal and a look at the joints after winter catches any damage.

Once debris packs a failed joint, the structure has nowhere to expand. The arrises crack and break away under the load and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

Work for main contractors and building owners

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

We work for building owners and managing agents on everything from one building to a spread of sites around Teston. One quote can cover more than one site, which keeps the paperwork simple.

What the job involves on each surface

Car park decks and ramps

Failed deck joints often show as leaks on the level below. We strip the old seal, prepare the edges and seal again, and we’ll tell you if any edges need repairing first.

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement.

Teston: questions and answers

Will you take on work at estates like Mereworth Business Centre, close to Teston?

Yes. We cover Teston and the area around it, including industrial estates, business parks and retail parks such as Mereworth Business Centre. Photos and a short description are enough for a first look.

Is a hospital such as Maidstone Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Can you follow the specification on our project?

Yes. Send it with your enquiry, and the quote will be based on it.

How long will the new sealant last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Doing it in-house

Redoing a failed joint usually costs more than getting it right at the outset, since all of it has to come out and the faces be 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. A poor seal in places like these tends to cost more to put right later.

Slabs, ramps and loading bays in Teston

Teston is about 29 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital. Rainfall across the South East, Teston included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.

Large sites such as Maidstone Hospital, 2.3 miles to the north-east of Teston, have car parks, service roads and long elevations with movement joints in brick and panels. Another example is Kings Hill Business Park (2.3 miles north-west of Teston), where floors and yards would be done in stages around the occupiers. Schools like Wateringbury Church of England Primary School often have long brick elevations with movement joints that age quietly.

Teston is about 4 miles west of Maidstone, in Kent. We send applicators to Teston for movement joints, handled exactly as we handle every other area. Teston is one of 931 places we cover in Kent. We also cover London, some 29 miles away.

Postcode districts covered here: ME18. Buildings on The Street, Courtlands and Church Street are within our area for movement joints. We also cover Red Hill (1 mile north-west), West Farleigh (1 mile south-east), Wateringbury (1 mile west), Barming Heath (1 mile east) and Hoppers Corner (1 mile east). Nearby towns on our patch include Maidstone (4 miles east), Sittingbourne (14 miles north-east), Sevenoaks (11 miles west), Royal Tunbridge Wells (11 miles south-west), Gravesend (12 miles north) and Tonbridge (8 miles south-west).
