Expansion joint sealing in Priddy's Hard, done properly
Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises. We work on precast concrete panel joints, podiums and floor movement joints and cladding panel joints, and the failures we are asked to look at most are expansion joints filled with dirt and stones and rain penetration at brick or block movement joints. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Priddy's Hard it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
In and around smaller places like Priddy's Hard, 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.

Diagnose, treat, sign off
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself normally taking a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. Rural sites near Priddy's Hard may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- A fixed quote follows, naming the sealant and its movement class.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
- Each joint is inspected and handed over with our 12-month guarantee.
Getting the site ready
- Send your site hours and access windows
- For older buildings, check the asbestos register before work
- Send any specification or drawings in advance

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.
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
Different surfaces, different methods
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.
Common problems we fix in Priddy's Hard
With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears, which is why depth control matters.
If one of these sounds familiar, it’s time for a closer look:
- Weathered movement joint sealant that no longer flexes
- Water getting into the wall through a failed joint
- Sealant pulling off the joint face
- Leaks through car park deck joints onto the level below
For an occupier at a site such as Cranbourne Industrial Estate, 1.1 miles south of Priddy's Hard, the joints at loading doors and dock levellers usually see the hardest wear.

Questions we are asked in Priddy's Hard
Is Priddy's Hard too far out for you?
No. Places such as Priddy's Hard are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
Does the sea air around Priddy's Hard change the choice of sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
How long before the joints can be used?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Is colour matching possible?
That depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.
Why has the sealant in our expansion joints split?
Typically the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting, rather than replacing like for like.

Keeping the joints sound
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. Our advice:
- Keep racking legs and heavy point loads off floor joints
- Keep scrapers and ploughs from dragging across joint sealant
- Clear dirt from joint lines during routine cleaning
- Report split or peeling joint sealant early
Fresh joint sealant needs its full cure time before it takes traffic or water. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.
