Expansion joint sealing in Wrotham

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. If you’re dealing with damp inside where a wall movement joint has failed and water dripping through deck or ramp joints, we can put it right, on car park decks and ramps, blockwork control joints and brickwork movement joints alike. A single leaking joint is often how a building in Wrotham first comes to us: 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 Wrotham, 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.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Wrotham, 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. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  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. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close
  • Confirm the product named in the specification

Questions about Wrotham

Do you take on work at healthcare sites like Sevenoaks Hospital?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

Will you take on work at estates like Invicta Business Park, close to Wrotham?

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

Are expansion joints and movement joints the same thing?

The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably.

Can you work while the building is occupied?

Typically, yes. We phase the work so most of the building stays in use.

What about RAMS and site documents?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

How do we ask for a quote?

You can use the quote form on this site; alternatively, ring 01277 525 020 or email drawings and photos. Include photographs or drawings if you have them.

Can the sealant be colour-matched?

Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.

Why deal with it now?

On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use without shutting the whole car park. Tell us what has to stay open and we will plan around it. Halls, stores and units around places like Wrotham may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

A quote for movement joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Surface by 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 and a flexible sealant where the joint moves more.

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Should maintenance staff do it?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.

Redoing a failed joint typically 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.

What we are called out for in Wrotham

On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant. The product has to be suited to the traffic.

Common reasons buildings call us in:

  • Torn sealant in brick or block movement joints
  • Joints where the bead has lost adhesion
  • Arrises breaking up along floor joints
  • Expansion joints filled with dirt and stones

Office parks like Invicta Business Park (to the east of Wrotham) have decks, ramps and clad elevations whose joints take movement every day.

What to look for in a quote

  • Their approach to joint depth and backing
  • Who will actually carry out the work
  • How they handle RAMS and site documents
  • Are they CHAS accredited or on Constructionline?
