Expansion joint sealing for businesses in Lashenden

Lashenden: questions and answers

Must our site in Lashenden stop work while the joints are done?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we will plan from there.

Can you take on a job at a hospital such as Benenden Hospital?

Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What exactly is a movement joint?

The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day, and sign any area that should be left alone.

What if the joint edges are damaged?

A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we will say so when we quote.

Which sealant will you use?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Expansion joint sealing in Lashenden, done properly

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, phasing bays so the car park can stay in use. Site teams most often ask us about previous reseals laid over old sealant and brittle, chalky sealant on external joints, on precast concrete panel joints, podiums and floor movement joints and cladding panel joints. Facilities teams, main contractors and managing agents in Lashenden tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

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

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Waterproofing layers buried beneath the sealant
  • Broken or spalled joint edges, which need repairing before any sealant goes in

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

Surfaces we seal

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

Slabs, ramps and loading bays in Lashenden

Lashenden lies roughly 40 miles out from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. Lashenden sits in one of the drier corners of the country, the South East. 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.

Large sites such as Benenden Hospital (3.9 miles south of Lashenden) have car parks, service roads and long elevations with movement joints in brick and panels.

Lashenden is about 10 miles west of Ashford, in Kent. We send applicators to Lashenden for movement joints. Lashenden is one of 931 places in Kent on our list for movement joints. For work in that direction, see our London page, about 40 miles away.

What sets the cost

What shapes the price:

  • Distance, for remote addresses
  • The size and state of each joint
  • Which sealant the job calls for
  • Any access equipment needed

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Before you send an enquiry

There’s no need for a formal survey. A few details are enough to get going:

  • Your programme or deadline
  • Any specification or named product
  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, speak to us on 01277 525 020 or email drawings and photos.

Surface by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in.

Brickwork and blockwork joints

Long brick and block elevations have movement joints at intervals. We use a sealant rated for the movement, typically low-modulus, with backing rod setting the depth.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Lashenden can form part of a wider programme.

From enquiry to sign-off

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Rural sites near Lashenden may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  4. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Preparing the site

  • Tell us what induction or permit system the site runs
  • Have the specification and drawings to hand
  • Agree which areas must stay open

Ask for a quote

Advice

What we are called out for in Lashenden

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.

Site and facilities staff are often the first to spot these:

  • Expansion joints filled with dirt and stones
  • Water dripping through deck or ramp joints
  • New sealant over old, now failing
  • Hardened, cracked sealant on exposed facades

For floors and slabs around Lashenden, the product is chosen for the traffic and the movement at each joint.

Questions to ask before you book

  • Their approach to joint depth and backing
  • Do they follow the manufacturer’s priming guidance?
  • Will failed sealant be removed rather than covered?
  • The named product and why it was chosen
