Expansion joint sealing near Wokingham

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Avoid parking heavy plant or pallets on joint lines
  • Check joints after long freezing spells
  • Put movement joints on the planned maintenance inspection round
  • Act on the first tear or lifting edge rather than waiting

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints.

Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster, and the damage spreads along the joint. Keeping the filler or sealant sound protects the floor.

Expansion joint sealing in Wokingham, done properly

The seal is what lets a movement joint do its job. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. We work on podiums and floor movement joints, brickwork movement joints and car park decks and ramps, and the failures we are asked to look at most are expansion joints split through the centre of the bead and brittle, chalky sealant on external joints. Most enquiries from Wokingham start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Large places such as Wokingham typically have industrial estates and business parks with warehouse and trade-counter floors. Every one has joints taking pallet trucks, forklifts or tyres, and the right filler or sealant depends on the traffic and the movement.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

FAQs: Wokingham

Will our site in Wokingham have to close for joint sealing?

Rarely. Work is phased around your operations. The phasing plan comes with the quote.

Will you take on work at estates like Station Industrial Estate, close to Wokingham?

Yes. We cover Wokingham and the area around it, including industrial estates, business parks and retail parks such as Station Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

Do you offer coloured sealant?

That depends on the product specified. Some ranges are wide, others limited, so we’ll confirm the colours available for the specified product with the quote.

How much does the work cost?

Every job gets its own fixed quote. To get one, call 01277 525 020 or use the quote form with a description of the work.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. We don’t remove asbestos-containing materials.

Does the weather affect joint sealing?

Sealant needs a dry joint and a temperature within the product’s range. Cold, damp or frosty mornings can stop work outside, so we plan with the forecast in mind.

What timescale should we allow for resealing expansion joints?

Allow a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. We confirm the timescale with the quote.

Building owners, agents and FMs in Wokingham

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.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

Common problems we fix in Wokingham

When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way unless width and product are reviewed.

Typical triggers for a call:

  • Expansion joints split through the centre of the bead
  • Joints where the bead has lost adhesion
  • Arrises breaking up along floor joints
  • Water dripping through deck or ramp joints

Hospital campuses such as Wokingham Hospital (less than half a mile east of Wokingham) grow in stages, leaving movement joints wherever new blocks meet old.

What your quote should include

  • Who will actually carry out the work
  • What site paperwork they can supply
  • Whether old or failed sealant will be cut out, not overlaid
  • Their plan for phasing and protecting the area

Questions to ask before you appoint anyone

On site: what to expect

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before the next one starts. Jobs in a large place like Wokingham are often on business parks, retail sites or campuses with their own sign-in and permit rules. Send the site rules with your enquiry and we will plan to them.

  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. Old sealant and filler are cut out and the joint faces cleaned back to sound material.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  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.

Getting the site ready

  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we will be in

Advice

Floors, slabs and movement joints in Wokingham

Rainfall across the South East, Wokingham included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. Wokingham lies roughly 33 miles out from central London. Warehousing clusters around the motorways that ring and radiate from London.

For estates staff at a university like University of Reading - Whiteknights Campus, 4.6 miles north-west of Wokingham, building and paving joints are part of the planned maintenance list. Estates like Station Industrial Estate, less than half a mile to the east of Wokingham, combine warehouse slabs, yards and loading bays, all with joints under wheels.

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Cracking or settlement that calls for an engineer’s assessment
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

If in doubt, speak to us on 01277 525 020 or email the details over and we’ll say what we think.
