Expansion joint sealing in Lenham Forstal

Joint design counts for as much as the sealant itself. 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, many sealant makers recommend a width-to-depth ratio, often around 2:1, and the bead is tooled so it grips the two faces alone. If you have arrises breaking up along floor joints and water getting into the wall through a failed joint, we can help, on blockwork control joints, brickwork movement joints and podiums and floor movement joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Lenham Forstal, that means joint design, primers and backing rod as standard.

Jobs around smaller places like Lenham Forstal are planned so the whole job is done in one visit, with the right materials on hand. Tell us the joint widths if you can, and what drives or walks over them.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or send details through our quote form and we will arrange a return visit.

What the job involves on each surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors, with a flexible sealant where movement is larger.

Brickwork and blockwork joints

Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

Expansion joint sealing around Lenham Forstal: points for this area

Lenham Forstal lies roughly 41 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.

For estates staff at a university like Canterbury Christ Church University (4.2 miles north-west of Lenham Forstal), building and paving joints are part of the planned maintenance list.

Lenham Forstal is about 8 miles north-west of Ashford, in Kent. Businesses, contractors and managing agents in Lenham Forstal can call on us for movement joints, as part of our coverage of Kent.

Owners, agents and contractors

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

When you manage a building on behalf of an owner, clear figures and clear communication matter. You get a fixed quote, an agreed scope and a walk round at the end.

Honest limits

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

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Concrete or masonry repairs along the arrises
  • Leaks coming from the membrane rather than the joint seal

FAQs: Lenham Forstal

Is Lenham Forstal too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Do we have to stop operations in Lenham Forstal while the joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Can the building stay open while you work?

Typically, yes. Phased work can be planned so areas stay in use.

Do you guarantee expansion joint work?

Each job is backed by a 12-month guarantee on the workmanship. Damage from later works or traffic loads outside the joint’s design isn’t a workmanship fault.

How long will the new sealant last?

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

Do you have public liability insurance?

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

Our process

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. Jobs in and around smaller places like Lenham Forstal are usually planned as a single visit, so we ask for photographs 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.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  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.

What we need from you

  • Flag any permit to work we’ll need
  • Agree which areas must stay open
  • Share your working hours and any access restrictions

Do you need expansion joint sealing in Lenham Forstal?

Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons, and it’s common on joints sealed in a hurry.

Most enquiries start with something like this:

  • Debris jammed in movement joints
  • Layers of sealant in a movement joint
  • Arrises breaking up along floor joints
  • Car park joints leaking onto vehicles below

Schools like The Lenham School often have long brick elevations with movement joints that age quietly.

Comparing quotes

  • Proof of insurance
  • Which product they’ll use, and why it suits the joint
  • Whether primer will be used where the manufacturer specifies it
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Look over external and deck joints after a hard winter
  • Include every elevation and deck joint in periodic inspections
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints
  • Plan racking layouts so feet don’t land on a joint

Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it. Regular sweeping keeps joint lines clear.

A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles, which is bad news for the concrete and the people parking below. Sealing the joint promptly stops it at source.
