Expansion joint sealing near Hawthorn

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

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Hawthorn can be grouped with others nearby. You will have a fixed quote before work starts.

  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.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  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.

Preparing the site

  • Let building users know which areas are affected
  • Tell us what induction or permit system the site runs
  • Agree which areas must stay open

Advice

Expansion joint sealing in Hawthorn, done properly

Long runs of brick or block have movement joints built in. Failed sealant here lets rain into the wall and can leave the joint full of debris. The old seal comes out, backing goes in and a sealant with the right movement class is applied. If you have chipped joint edges on forklift routes and sealant pulling off the joint face, we can help, on brickwork movement joints, blockwork control joints and cladding panel joints alike. Searching for sealant specialists in Hawthorn? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Halls, schools and small commercial buildings near places like Hawthorn have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

Work we carry out comes with a 12-month guarantee. Should something we installed fail, speak to us on 01277 525 020 or email the details over and we’ll come back to it.

Aftercare for building managers

Regular inspection catches problems early. Specifically:

  • Plan racking layouts so feet don’t land on a joint
  • Keep traffic off new joints until the cure time is up
  • Check joints after long freezing spells
  • Act on the first tear or lifting edge rather than waiting

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.

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.

When to bring in a specialist

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Do you need expansion joint sealing in Hawthorn?

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

If one of these sounds familiar, it’s time for a closer look:

  • Arrises breaking up along floor joints
  • Sealant pulling off the joint face
  • Rain penetration at brick or block movement joints
  • Torn sealant in brick or block movement joints

Across sites such as Chislet Business Park (2.6 miles south of Hawthorn), floor and movement joints can be sealed in phases so units keep working.

How to choose a sealant contractor

Leave it or put it right?

On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open. Tell us what has to stay open and we’ll plan around it. Around Hawthorn, it’s better to renew all the failing joints at once, rather than one at a time. Send photos of each area and we’ll quote for the lot.

Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why us?

  • Work carried out by CSCS-carded applicators
  • One number for every site we cover
  • Matching to RAL references, product permitting
  • Health and safety: CHAS accredited

Where floor joints take the most wear near Hawthorn

Hawthorn is within about 2 miles of the coast. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so a failed joint lets more in and the edges break up sooner. Less than 3 miles from Hawthorn there are two named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

Schools such as Reculver Church of England Primary School have movement joints in their walls and floors that are easy to overlook. A healthcare site such as Queen Victoria Memorial Hospital, 1.4 miles to the west of Hawthorn, depends on car parks, ramps and service yards whose joints take traffic all day.

Hawthorn is about 2 miles east of Herne Bay, in Kent. Anywhere in CT6, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Hawthorn is one of 931 places in Kent on our list for movement joints. We also cover London, some 56 miles away.

What the job involves on each surface

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. The sealant needs the right movement capability and a controlled depth.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement.

Common questions from Hawthorn clients

Does your area include sites such as Eddington Business Park, near Hawthorn?

Yes. Estates, retail parks and business parks around Hawthorn, Eddington Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Can you take on a job at a hospital such as Queen Victoria Memorial Hospital?

Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

What’s the difference between an expansion joint and a movement joint?

They’re closely related. A movement joint allows for expansion, contraction, shrinkage and loading while the sealant stops grit and water getting in.

Is movement joint sealing guaranteed?

The workmanship is guaranteed for 12 months from sign-off and we hold public liability insurance. Keeping joints clear of debris helps them last.

Does the weather affect the work?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Do you work in Hawthorn?

Yes. We cover Hawthorn, and you can speak to us on 01277 525 020 or email the details over to get started.
