Slabs, ramps and loading bays in Matchams
At least three named trading, business or retail sites lie within about 3 miles of Matchams. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Matchams is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, while winter salting gets into any joint left open.
At places like Pintail Business Park, 2.1 miles to the north-east of Matchams, joints are sealed a section at a time so operations carry on. If you manage units on an estate such as Millstream Trading Estate, 2 miles to the north-east of Matchams, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Expansion joint sealing for commercial buildings in Matchams
Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. We work on blockwork control joints, precast concrete panel joints and car park decks and ramps, and what we are called in for most is spalled or broken joint edges in floors and decks and leaks through car park deck joints onto the level below. Most enquiries from Matchams start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
Halls, schools and small commercial buildings near places like Matchams have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Common questions from Matchams clients
Can you work on a hospital site such as St Leonards Hospital?
Yes, healthcare and care buildings are part of our work. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Millstream Trading Estate, near Matchams, within your area?
Yes, sites like Millstream Trading Estate are within our area, along with the rest of Matchams. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.
Do you cover Matchams?
Yes. Matchams is in our area and the rest of Hampshire. To discuss a job, phone 01277 525 020 or email the details over.
Are expansion joints and movement joints the same thing?
The terms overlap a great deal. A movement joint allows for expansion, contraction, shrinkage and loading, and the seal across it keeps water and debris out.
What if there’s asbestos in the old mastic?
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. We don’t remove asbestos-containing materials.
What sealant do you use in movement joints?
Whatever suits the joint and the specification. We name the proposed product in the quote, so you know what’s going in.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
How the job changes by surface
Podium joints
Podium joints often sit within a waterproofing system. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.
Concrete and precast panel joints
Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.
Signs you need expansion joint sealing in Matchams
Repeated failure often traces back to the wrong product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability.
Look out for the following:
- Hardened, cracked sealant on exposed facades
- Chipped joint edges on forklift routes
- Debris jammed in movement joints
- Leaks through car park deck joints onto the level below
Sites like St Leonards Hospital (1.8 miles west of Matchams) carry ambulances, deliveries and visitors’ cars over their road and deck joints.
Questions to ask before you book
- Their public liability cover
- Whether old or failed sealant will be cut out, not overlaid
- Their approach to joint depth and backing
- Their pre-qualification and accreditations
Aftercare for building managers
Cleaning and maintenance staff play a part too. Share these points with them:
- Raise snow-clearing blades over deck joints where possible
- Keep product details with the building records for the next reseal
- Inspect exposed joints once the cold weather has passed
- Keep racking legs and heavy point loads off floor joints
Our workmanship on movement joints carries a 12-month guarantee. Record which product went into which joints in the building file so future maintenance isn’t guesswork.
An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall. Keeping the seal sound avoids all of that.
For managing agents and facilities managers

Cost factors for movement joints
To price the job, we consider:
- Removal of failed or old sealant
- Which sealant the job calls for
- Travel to remote or island sites
- Any access equipment needed
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
What we need to price the job
It doesn’t need to be a full survey. These details are enough to start:
- The product your specification calls for
- Rough lengths or quantities, or drawings if you have them
- The postcode of the building
- The asbestos register, for older buildings
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or email the details over.
