Do you need expansion joint sealing in Faringdon?

When a bead pulls away from one face, it has lost adhesion. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.

Look out for the following:

  • Water dripping through deck or ramp joints
  • Weathered movement joint sealant that no longer flexes
  • Arrises breaking up along floor joints
  • Sealant pulling off the joint face

On a site such as Faringdon Business Park, 1.4 miles to the south-west of Faringdon, the movement joints are in car park slabs, paving and building elevations.

Choosing a commercial sealant contractor

Expansion joint sealing in Faringdon

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. If you have new sealant over old, now failing and water getting into the wall through a failed joint, we can put it right. One point of contact handles commercial sealant work in Faringdon from the first photos to the final walk-round, whether it’s one building or several.

Rural business units around smaller places such as Faringdon often have new slabs laid inside older buildings. Saw-cut and construction joints in those floors need the right filler or sealant for the forklifts and trolleys that use them.

We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and if something we did falls short, we return to it.

Site staff or a sealant specialist?

Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

On site: what to expect

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. If neighbouring businesses or buildings around Faringdon need work too, visits can be combined. Mention the building’s opening times and we will work within them.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. We compare each joint’s width with the movement and the sealant’s capability, and flag anything that needs an engineer.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

Getting the site ready

  • Move anything stored against the joints
  • Warn occupants and staff about the work
  • Send asbestos survey details if the building is pre-2000

What happens if it’s left?

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed and we will tell you honestly. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

After the work

For the best life from the joints:

  • Keep racking legs and heavy point loads off floor joints
  • Act on the first tear or lifting edge rather than waiting
  • Inspect movement joints alongside other routine building checks
  • Keep product details with the building records for the next reseal

On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.

When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one so you can prioritise and budget. We can suggest an order, worst joints first.

Joints that move: notes for Faringdon

The 3 miles around Faringdon take in two named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Faringdon lies roughly 65 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.

Across sites such as Stanford in the Vale Business Park, 2.9 miles to the east of Faringdon, floor and movement joints can be sealed in phases so units keep working. In a school such as Faringdon Community College, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Questions about Faringdon

Is Faringdon too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you work on a hospital site such as Faringdon Day Hospital?

Yes. We work in healthcare settings as well as offices and schools. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Do the joint edges need to be sound before sealing?

Sound edges are essential. If they’re damaged, we will say so before any sealing.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.
