Where floor joints take the most wear near Platt's Heath
Platt's Heath lies roughly 39 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. The South East is one of the drier parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint.
Campuses like Canterbury Christ Church University, 3.1 miles north of Platt's Heath, mix old and new buildings, with movement joints wherever they meet. On a site such as Roebuck Business Park, 1.4 miles north-west of Platt's Heath, the movement joints are in car park slabs, paving and building elevations.

About our expansion joint sealing in Platt's Heath
Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. Site teams most often ask us about joints where the bead has lost adhesion and rain penetration at brick or block movement joints, across cladding panel joints, podiums and floor movement joints and blockwork control joints. For commercial sealant work in Platt's Heath, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Jobs around smaller places like Platt's Heath are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we will take it from there.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Damaged metal nosings or cover plates over a joint
- Changing the joint layout or spacing of a structure
- Cracking or settlement that calls for an engineer’s assessment
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think before you book.
Where we work in Platt's Heath

Leave it or put it right?
Spot repairs can be useful on a tight budget. But if the rest of the run is the same age and product, it’s usually not far behind. Where it helps, we quote both options. One visit to deal with every failing joint makes more sense than several trips to a place like Platt's Heath. Send photographs of each area and we will quote for the lot.
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

What else we do in Platt's Heath
Signs you need expansion joint sealing in Platt's Heath
Sun, rain and frost age external movement joints. In time the bead chalks, stiffens and cracks, so it can’t follow the movement any more.
Common reasons buildings call us in:
- Joints where the bead has lost adhesion
- Debris jammed in movement joints
- Hardened, cracked sealant on exposed facades
- Layers of sealant in a movement joint
Schools such as Platts Heath Primary School have movement joints in their walls and floors that are easy to overlook.

How the job changes by surface
Internal floor movement joints
Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler.
Car park decks and ramps
Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again, and we will tell you if any edges need repairing first.
Questions we are asked in Platt's Heath
Do you cover business parks and estates near Platt's Heath, such as Roebuck Business Park?
Yes, sites like Roebuck Business Park are within our area, along with the rest of Platt's Heath. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.
Will our site in Platt's Heath have to close for joint sealing?
Rarely. Work is phased around your operations. The phasing plan comes with the quote.
Is it fine to apply new sealant on top of old?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
Can you work while the building is occupied?
Usually, yes. We phase the work so most of the building stays in use, with each area protected and signed.
What site paperwork can you supply?
Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.
Diagnose, treat, sign off
Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If others near Platt's Heath need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.
- We start with photographs, approximate lengths and any drawings, visiting where needed.
- We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
- Old sealant and debris are cut out of every joint.
- 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.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Getting the site ready
- Send your site hours and access windows
- Flag any permit to work we will need
- Point out parking and an unloading spot

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
General trades versus a specialist
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
