About our expansion joint sealing in Wrotham Heath

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 while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. We work on car park decks and ramps, precast concrete panel joints and podiums and floor movement joints, and the failures we’re asked to look at most are weathered movement joint sealant that no longer flexes and car park joints leaking onto vehicles below. Searching for sealant specialists in Wrotham Heath? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

In and around smaller places like Wrotham Heath, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually 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 we clear our waste as we work. For a building around Wrotham Heath, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  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.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Agree which areas must stay open

Advice

Floors, slabs and movement joints in Wrotham Heath

Wrotham Heath is in the South East, one of the UK’s drier regions. 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. Wrotham Heath is about 24 miles from central London. The roads out of London are lined with trade parks and distribution sheds.

Business parks such as Invicta Business Park (1.1 miles north-west of Wrotham Heath) have car parks, paved areas and long brick and panel elevations, all with movement joints. Across sites such as Bourne Enterprise Centre, 1.7 miles west of Wrotham Heath, floor and movement joints can be sealed in phases so units keep working. Schools like Platt Church of England Voluntary Aided Primary School often have long brick elevations with movement joints that age quietly.

Wrotham Heath is about 7 miles east of Sevenoaks, in Kent. Any commercial site in Wrotham Heath is covered, whether it’s a single job or part of a planned programme. Wrotham Heath is one of 931 places we cover in Kent. Sites around London have their own page, about 24 miles away.

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. Acting at the first split keeps the cost down. For buildings around smaller places like Wrotham Heath, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why us?

  • Constructionline member
  • 12-month guarantee on workmanship
  • A range of standard colours, depending on the product
  • One number for every site we cover

Questions we are asked in Wrotham Heath

Is Wrotham Heath off your patch?

No. Places such as Wrotham Heath are covered as much as the big towns. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Do you cover business parks and estates near Wrotham Heath, such as Invicta Business Park?

Yes, sites like Invicta Business Park are within our area, along with the rest of Wrotham Heath. Photos and a short description are enough for a first look.

What will the job cost?

Each job is quoted on its own details. For yours, phone 01277 525 020 or email the details over with a description of the work.

How long do sealant joints last?

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

Is colour matching possible?

That depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Can you work while the building is occupied?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Changing the joint layout or spacing of a structure
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Movement on a scale no sealant is meant to absorb

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

What we seal

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

Keeping the joints sound

A few simple habits keep the new joints working:

  • Leave barriers in place until fresh joint sealant has cured
  • Act on the first tear or lifting edge rather than waiting
  • Inspect movement joints alongside other routine building checks
  • Sweep decks, ramps and floors so grit doesn’t collect in the joints

Movement joints belong on the planned maintenance inspection list. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. If anything looks wrong, ring 01277 525 020 or send details through our quote form with photographs.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We can suggest an order, worst joints first.
