How we handle expansion joint sealing in Test Valley
The seal is what lets a movement joint do its job. Once it fails, water, grit and debris get in, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. The enquiries we see most involve arrises breaking up along floor joints and layers of sealant in a movement joint, on cladding panel joints, car park decks and ramps and blockwork control joints. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Test Valley is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Test Valley, 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.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Keeping the joints sound
For the best life from the joints:
- Include every elevation and deck joint in periodic inspections
- Act on the first tear or lifting edge rather than waiting
- Note which joints were done, when, and with what
- Look over external and deck joints after a hard winter
On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead.
A failed deck joint lets water straight through to the level below. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Resealing early limits the damage.
Our process
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. For a building around Test Valley, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.
- 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.
- Every joint is cleared of the failed seal and any grit packed into it.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Each area is handed back after its cure time, under our 12-month guarantee.
What we need from you
- Make sure the joints can be reached
- Confirm the product named in the specification
- Tell us your opening times and when work is allowed

When something else is needed
Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is one of these:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Waterproofing layers buried beneath the sealant
- Broken or spalled joint edges, which need repairing before any sealant goes in
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.
Surfaces we seal
- Brickwork movement joints
- Blockwork control joints
- Car park decks and ramps
- Podiums and floor movement joints
- Precast concrete panel joints
- Cladding panel joints
Where floor joints take the most wear near Test Valley
Test Valley sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Central London is about 59 miles from Test Valley. The roads out of London are lined with trade parks and distribution sheds; their floors carry heavy traffic every shift.
Around Test Valley, open joints collect water and debris, and the arrises are the next to go; we’ll tell you if the edges need repairing first.

Site staff or a sealant specialist?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
When to call us in Test Valley
Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.
These are often picked up first by site or facilities staff:
- Arrises breaking up along floor joints
- Sealant pulling off the joint face
- Rain penetration at brick or block movement joints
- Weathered movement joint sealant that no longer flexes
For floors and slabs around Test Valley, the product is chosen for the traffic and the movement at each joint.
What your quote should include
- Will failed sealant be removed rather than covered?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?

Surface by surface
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability, and we will confirm the colours available for the specified product.
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler and a flexible sealant where the joint moves more.
Questions we are asked in Test Valley
Must our site in Test Valley 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.
Is Test Valley off your patch?
No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
Why do our movement joints keep failing?
The way it has failed typically tells us why: tearing down the centre means too much movement, and lifting off one side means poor adhesion. Sometimes the edge material itself has failed.
What’s the quickest route to a quote?
It works in four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
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’ll confirm the colours available for the specified product.
What’s the difference between an expansion joint and a movement joint?
It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint and both need a flexible seal.
