Expansion joint sealing for Hacklinge sites

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Damaged metal nosings or cover plates over a joint
  • Leaks coming from the membrane rather than the joint seal
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

Not sure which it is? You can call the office on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Joints and surfaces we work on

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

How we handle expansion joint sealing in Hacklinge

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We’ll tell you if the edges need repairing before sealing and phasing can keep areas working. If you are dealing with damp inside where a wall movement joint has failed and joints packed with grit and debris, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Hacklinge from the first photographs to the final walk-round, for single jobs and planned programmes alike.

For a site near Hacklinge, measurements and photographs 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. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Should maintenance staff do it?

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.

Surface by surface

Podium joints

Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. We prepare the faces thoroughly and prime where the maker calls for it.

Our process

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. If others near Hacklinge need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  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. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
  • Move anything stored against the joints

Advice

Expansion joint sealing in Hacklinge: the local picture

Hacklinge lies within about 3 miles of the sea. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, which is why split joints are worth sealing before the edges deteriorate. Rainfall across the South East, Hacklinge included, is lower than in many parts of the UK. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint.

In a school such as Worth Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak. Office parks like Birnham Farm Business Centre (to the north-west of Hacklinge) have decks, ramps and clad elevations whose joints take movement every day. A healthcare site such as Victoria Hospital (2.2 miles south-east of Hacklinge) depends on car parks, ramps and service yards whose joints take traffic all day.

Hacklinge is about 2 miles north-west of Deal, in Kent. Hacklinge sits inside our coverage, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 931 places in Kent. London is covered too, some 65 miles away.

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Note which joints were done, when, and with what
  • Clear dirt from joint lines during routine cleaning
  • Inspect exposed joints once the cold weather has passed
  • Put movement joints on the planned maintenance inspection round

On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load and the reseal becomes an edge repair as well. A sound seal keeps the joint working.

Your questions answered

Is Hacklinge off your patch?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as Victoria 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.

What if the joint edges are damaged?

Sealant needs sound faces to bond to, so broken or crumbling edges have to be repaired first. Where it’s visible beforehand, we will say so when we quote.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit before quoting.

What causes movement joint sealant to fail?

The common causes are poor preparation, three-sided adhesion, the wrong movement class and weathering. Working out the cause comes first.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Building owners, agents and FMs in Hacklinge

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in Hacklinge can sit alongside others in a wider programme across Kent.
