Surface by surface

Joints between different materials

Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement priming where the maker calls for it.

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. The joints need a low-modulus sealant with enough movement capability, and we will confirm the colours available for the specified product.

Expansion joint sealing in Force Green, done properly

Floor movement joints in warehouses, retail and public buildings carry wheeled traffic. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing and phasing can keep areas working. If you’re dealing with joints where the bead has lost adhesion and expansion joints split through the centre of the bead, we can put it right, on cladding panel joints, brickwork movement joints and blockwork control joints alike. Most enquiries from Force Green start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Jobs around smaller places like Force Green 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 is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

When something else is needed

Being straight saves everyone time. Fresh joints won’t solve:

  • Proprietary pre-formed expansion joint systems
  • Crumbling edges that would give a new bead nothing sound to grip
  • Movement on a scale no sealant is meant to absorb

If you’re not sure, just ring 01277 525 020 or email us and we will give you a straight answer.

Joints and surfaces we work on

Questions about Force Green

Can you work on a hospital site such as Tandridge Priory?

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 Force Green too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Who decides which product is used?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you seal car park deck joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement.

What sealant do you use in movement joints?

It depends on the movement, exposure and traffic. Facades often take a low-modulus silicone; floors and decks usually need a polyurethane.

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Site staff or a sealant specialist?

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Commercial clients in Force Green

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

For main contractors, we work as the sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

How a job runs

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If others near Force Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. Each joint is inspected and handed over with our 12-month guarantee.

What we need from you

  • Confirm the product named in the specification
  • Share the asbestos register for older buildings
  • Move anything stored against the joints

Force Green is in the South East, one of the UK’s drier regions. External slab and deck joints still need a dry, clean joint to seal, and where de-icing salt is spread in winter, open joints let it in.

Large sites such as Tandridge Priory (to the south-west of Force Green) have car parks, service roads and long elevations with movement joints in brick and panels. In and around Force Green, the right filler or sealant for each joint depends on the traffic and the movement it takes.

What happens if it’s left?

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. If the material either side is sound, a properly prepared reseal restores the joint. If the edges have broken up, we will tell you they need repairing first. Converted and older buildings near places like Force Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.
