About expansion joint sealing in Hampshire

A movement joint only works while its seal does. Once it fails, water, grit and debris get in; the joint jams, its edges take the load and the arrises spall. Dealt with early, it stays a sealant job rather than a concrete or masonry repair. Site teams most often ask us about leaks through car park deck joints onto the level below and weathered movement joint sealant that no longer flexes, on blockwork control joints, precast concrete panel joints and cladding panel joints.

We schedule the visit to fit the site hours and access windows you give us. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area.

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.
Any broken arrises or friable edges are flagged before work goes further.
A sealant suited to the movement and traffic is laid to depth and tooled.
Each area is handed back after its cure time, under our 12-month guarantee.

Pricing in Hampshire

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.

Expansion joint sealing across Hampshire: the area picture

Industrial estates, business parks and retail parks around Basingstoke, Winchester and Gosport and elsewhere in Hampshire typically have floor and slab joints under daily traffic. The right filler or sealant for each joint depends on the traffic and the movement.

London and the South East are among the drier parts of the UK, but external sealing in Hampshire still needs a dry joint and the right temperature, and damp or frosty mornings can hold it up. Coastal places in Hampshire often have hotels, guest houses and holiday accommodation with busy seasons, so work is often best planned for quieter months.

Basingstoke: For a school such as King's Furlong Infant School and Nursery, playground and building joints can be done in the holidays. Centres like The Malls, 0.6 miles to the east of Basingstoke, have mall floors and service decks whose joints carry steady traffic.

Signs you need expansion joint sealing

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, typically means the joint or product wasn’t right for the movement. The same product in the same joint tends to fail again.

What tends to prompt an enquiry:

Expansion joints split through the centre of the bead
Previous reseals laid over old sealant
Arrises breaking up along floor joints
Hardened, cracked sealant on exposed facades

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Redoing a failed joint normally 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.

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Grit and water fill the gap and the material either side breaks up. Resealing early keeps the work to sealant.

When it isn’t the sealant

Our job is the joint, not everything around it. Sealant alone won’t deal with:

Joints too narrow for the movement, which need redesigning by the engineer
Waterproofing layers buried beneath the sealant
Structural movement beyond what the joints were designed for (that needs a structural engineer)

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Hampshire can form part of a wider programme across Hampshire.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first.

FAQs: Hampshire

Is it fine to apply new sealant on top of old?

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

How long will the new sealant last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Is colour matching possible?

That depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Which product is best for expansion joints?

Movement capability matters most as set out in BS EN ISO 11600. Hybrid or MS polymer products suit some mixed-material joints.

What’s the difference between an expansion joint and 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.

Is movement joint sealing guaranteed?

It’s backed by our 12-month guarantee. Tell us straight away if a joint we sealed gives trouble in that time.
