Where floor joints take the most wear near Blackgang
With the shore within about 1 mile, Blackgang counts as a coastal location. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. Rainfall across the South East, Blackgang included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and winter de-icing salt on car parks and ramps works into any open joint.
In a school such as Niton Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

How we handle expansion joint sealing in Blackgang
A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water; 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. The enquiries we see most involve car park joints leaking onto vehicles below and previous reseals laid over old sealant, on blockwork control joints, precast concrete panel joints and cladding panel joints. A single leaking joint is often how a building in Blackgang first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Blackgang, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.
We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Why deal with it now?
Sealing over a failed movement joint is a common shortcut. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. We cut out the old seal and prepare the faces every time. Converted and older buildings near places like Blackgang tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

How a job runs
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. For a building around Blackgang, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.
- We look at the joints, their width and how they’ve failed.
- A fixed quote follows, naming the sealant and its movement class.
- The failed seal is removed and both faces are cleaned until sound and dry, and we tell you if any edges need repairing first.
- We control the depth with backing rod or, in shallow joints, bond-breaker tape.
- Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
- We check every joint before sign-off, and the work carries our 12-month guarantee.
Preparing the site
- Point out any areas we must not close
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000

How the job changes by surface
Car park decks and ramps
Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix.
Do you need expansion joint sealing in Blackgang?
Sealant peeling cleanly off one side is an adhesion failure. Poor preparation, a skipped primer, or sealant bonded to the back of the joint are typical reasons and it often shows on rushed work.
It’s worth sending us details if you spot any of the following:
- Rain penetration at brick or block movement joints
- Car park joints leaking onto vehicles below
- Hardened, cracked sealant on exposed facades
- Joints where the bead has lost adhesion
Hospitals like Whitecroft Hospital, 5.7 miles north of Blackgang, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
Questions we are asked in Blackgang
Does the sea air around Blackgang change the choice of sealant?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
Is Blackgang too small for you to travel to?
No. Places such as Blackgang are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you handle several sites?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
What causes movement joint sealant to fail?
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. Broken edges are a third possibility.
Can you follow the specification on our project?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
Which product is best for expansion joints?
Whatever suits the joint and the specification. We name the proposed product in the quote.
Will you quote for a small job?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Keep traffic off new joints until the cure time is up
- Treat a small split as a warning, not a cosmetic issue
- Inspect exposed joints once the cold weather has passed
- Keep scrapers and ploughs from dragging across joint sealant
Movement joints belong on the planned maintenance inspection list. Early splits and edges starting to lift show up on a routine check and long before edges start to break. If anything looks wrong, call the office on 01277 525 020 or email the details over with photos.
On a multi-storey car park, a failed joint normally shows up as a leak onto the deck underneath. Salty water dripping through stains soffits and lands on parked vehicles and it can affect the structure over time. Sealing the joint promptly stops it at source.
