Expansion joint sealing for commercial buildings in Lydden

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. We work on car park decks and ramps, precast concrete panel joints and blockwork control joints, and the usual reasons a site gets in touch are expansion joints filled with dirt and stones and previous reseals laid over old sealant. For commercial sealant work in Lydden, you deal with one contact from quote to sign-off, whether it’s one building or several.

For a site near Lydden, measurements and photos up front mean one trip where possible, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What we’re called out for in Lydden

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it, so we tell you if the edges need repairing first.

Any of the following is a good reason to get the joints checked over:

  • Layers of sealant in a movement joint
  • Arrises breaking up along floor joints
  • Sealant pulling off the joint face
  • Joints packed with grit and debris

On a site such as White Cliffs Business Park, which lies east of Lydden, the movement joints are in car park slabs, paving and building elevations.

Questions to ask before you book

  • How the existing material will be dealt with
  • Their approach to joint depth and backing
  • Whether their applicators hold CSCS cards
  • How long is the guarantee, and what does it include?

Choosing a commercial sealant contractor

For managing agents and facilities managers

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Lydden can form part of a wider programme across Kent.

Looking after the joints

Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:

  • Put movement joints on the planned maintenance inspection round
  • Check joints after long freezing spells
  • Report split or peeling joint sealant early
  • Plan racking layouts so feet don’t land on a joint

Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file so future maintenance isn’t guesswork.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Resealing promptly prevents internal damage.

Surface by surface

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

Brickwork and blockwork joints

A brick movement joint full of old mortar or debris can’t close. We clear the joint fully before sealing and flag any joint that seems undersized.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work normally takes a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints, and our waste is bagged and taken away as we go. If others near Lydden need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Move anything stored against the joints
  • Send any specification or drawings in advance

Quotes

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.

Lydden: questions and answers

Do you cover business parks and estates near Lydden, such as White Cliffs Business Park?

Yes. Our area takes in Lydden and its surroundings, with estates and business parks such as White Cliffs Business Park included. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Is a smaller place like Lydden outside your area?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Are you insured?

Yes. We’re fully insured, and the certificate can go with your quote.

Why has the sealant in our expansion joints split?

Adhesion failure, cohesive failure, edge breakdown and UV ageing account for most cases. We diagnose which one it is before resealing.

Can the building stay open while you work?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Where floor joints take the most wear near Lydden

Lydden is in the South East, one of the UK’s drier regions. Outside joints in yards and car parks still have to be dry before sealing, and where de-icing salt is spread in winter, open joints let it in. Central London is about 62 miles from Lydden. The South East has large numbers of industrial estates and warehouses along the motorway corridors; their floors carry heavy traffic every shift.

Hospitals like Buckland Hospital (to the south-east of Lydden) have multi-storey or surface car parks whose joints carry vehicles round the clock. In a school such as Lydden Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Lydden is about 3 miles north-west of Dover, in Kent. Lydden sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 931 places in Kent, large and small. London is covered too, around 62 miles from Lydden.

Nearby towns on our patch include Canterbury (11 miles north-west), Dover (3 miles south-east), Folkestone (6 miles south-west), Ramsgate (14 miles north-east), Deal (8 miles north-east) and Herne Bay (15 miles north).

When something else is needed

Not every problem is a sealant problem, and we are upfront when that’s the case. It won’t fix:

  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Damaged metal nosings or cover plates over a joint

Not sure which it is? You can speak to us on 01277 525 020 or send photos by email and we will tell you honestly.
