How we handle expansion joint sealing in Bassett
Joint design counts for as much as the sealant itself. 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. Most enquiries involve weathered movement joint sealant that no longer flexes and rain penetration at brick or block movement joints, across blockwork control joints, cladding panel joints and podiums and floor movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Bassett it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Small units near places like Bassett are often converted farm buildings with new concrete floors. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Do you need expansion joint sealing in Bassett?
Weathering wears down sealant on exposed elevations and decks. In time the bead chalks, stiffens and cracks.
Things that normally lead to an enquiry:
- Weathered movement joint sealant that no longer flexes
- Arrises breaking up along floor joints
- New sealant over old, now failing
- Leaks through car park deck joints onto the level below
Across sites such as Northbrook Industrial Estate (0.9 miles south-west of Bassett), floor and movement joints can be sealed in phases so units keep working.

- Whether their applicators hold CSCS cards
What happens if it’s left?
On a car park, resealing joints in phases keeps the deck open. Phased work by bay or zone lets the rest stay in use, compared with a full closure. We agree phasing with you before work starts. In a smaller place such as Bassett, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.
The product called for affects the cost, as does the preparation each joint needs. Access, phasing and site requirements come into it too.
Why us?
- Our applicators hold CSCS cards
- Constructionline member for supplier checks
- Specification-led, product-correct work
- Coloured sealants to suit the setting, where available

Floors, slabs and movement joints in Bassett
Bassett sits close to the coast, within about 3 miles. Open joints in coastal car parks and yards let in salt-laden water as well as grit, so it pays to keep them sealed. Central London is about 69 miles from Bassett. The South East has large numbers of industrial estates and warehouses along the motorway corridors.
A campus such as University of Southampton, 1 mile south-east of Bassett, has long runs of movement joint in its buildings, decks and paving. Hospital campuses such as Princess Anne Hospital, 1.1 miles to the west of Bassett, grow in stages, leaving movement joints wherever new blocks meet old.
Bassett is about 2 miles north-west of Southampton, in Southampton. We send applicators to Bassett for movement joints, handled exactly as we handle every other area. 30 places across Southampton fall within our area, Bassett among them.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:
- Waterproofing layers buried beneath the sealant
- Broken or spalled joint edges, which need repairing before any sealant goes in
- Cracking or settlement that calls for an engineer’s assessment
If in doubt, call 01277 525 020 or use the quote form and we’ll say what we think before you book.
What we seal
- Car park decks and ramps
- Precast concrete panel joints
- Podiums and floor movement joints
- Blockwork control joints
- Brickwork movement joints
- Cladding panel joints
Aftercare for building managers
Keep the joints in good shape with a few simple steps:
- Reopen bays and walkways only after the stated cure time
- Check joints after long freezing spells
- Include every elevation and deck joint in periodic inspections
- Record the sealant used and the date in the O&M file
Add every elevation, deck and floor joint to your inspection round. A periodic look picks up tears and lifting before water gets in, when they’re still cheap to deal with. Should you spot a problem, you can phone 01277 525 020 or send details through our quote form and send a picture.
Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one. We can suggest an order, worst joints first.
Questions about Bassett
Is Bassett too small for you to travel to?
Not at all. Bassett is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can you work at a site such as Shirley Retail Park, by Bassett?
Yes. Estates, retail parks and business parks around Bassett, Shirley Retail Park among them, are all within reach. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
How do we ask for a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or send photos by email. Include photos or drawings if you have them.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
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. We flag it at the quote stage where we can see it.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Are expansion joints and movement joints the same thing?
Movement joint is the broad term for any joint built in to let a structure move. In everyday use the two names are often swapped and the way they’re sealed is similar.
Doing it in-house
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Diagnose, treat, sign off
On arrival, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, and the work normally takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. For a site in Bassett, we plan so the whole job is done in one go where possible. Photos with rough sizes let us arrive with everything needed.
- Photos, joint lengths and drawings come to us, or we visit.
- Joint widths and expected movement are checked against what the sealant can take and tell you if the design looks wrong for the movement.
- Old sealant and debris are cut out of every joint.
- Any broken arrises or friable edges are flagged before work goes further.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Getting the site ready
- Explain the parking and delivery arrangements
- Send any specification or drawings in advance
- Share the asbestos register for older buildings
