Expansion joint sealing in Newbury

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. Every one calls for a sealant picked for its movement, exposure and traffic. If you’re dealing with chipped joint edges on forklift routes and sealant pulling off the joint face, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Newbury, that means joint design, primers and backing rod as standard.

In a town the size of Newbury, floor joints are mostly in industrial and trade units, supermarkets and car parks. Smaller units can’t stop work for long, so we plan around the occupier’s hours.

Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

From enquiry to sign-off

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 reopened once the sealant allows before we move to the next. Most work in Newbury is one building at a time: a school, a unit, an office or a block. Your photos, drawings or a site visit come first, followed by a fixed quote.

  1. First, the joints are inspected for width, movement and the type of failure.
  2. A fixed quote follows, naming the sealant and its movement class.
  3. The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
  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. Finished joints are checked and backed by our 12-month guarantee.

What we need from you

  • Share the asbestos register for older buildings
  • Agree which areas must stay open
  • Move anything stored against the joints

Joints that move: notes for Newbury

Newbury has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Newbury is about 53 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

Phasing is what makes joint work possible on busy sites such as Raceview Business Centre (0.5 miles east of Newbury): one bay, aisle or car park row at a time. Places like Parkway Shopping Centre (under half a mile north of Newbury) put trolleys over floor joints inside and cars over slab joints outside. Sites like West Berkshire Community Hospital, 1.5 miles east of Newbury, carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Newbury is about 15 miles west of Reading, in West Berkshire. We cover commercial sites throughout Newbury. Our West Berkshire coverage takes in 140 places. We also cover Reading, some 15 miles away.

We cover the RG14, RG19, RG18 and RG20 postcode districts. Among the streets we cover are Market Street, London Road and Donnington Square. Newbury sits on or close to the A4 and A339, which helps when planning parking and deliveries for the job. We also cover Greenham (1 mile south-east), Sandleford (1 mile south), Skinners Green (2 miles south-west), Wash Common (2 miles south-west) and Enborne (2 miles west) for movement joints. A short drive away, we cover Thatcham (3 miles east), Burghfield Common (11 miles east), Hungerford (8 miles west), Fords Farm (13 miles east), Little Heath (12 miles east) and Calcot (12 miles east). Newbury ranks among the main centres of West Berkshire, with offices, shops, schools and other public and commercial buildings.

Owners, agents and contractors

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, and each stage is agreed with your contact.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Surface by surface

Internal floor movement joints

Wheeled traffic chips floor joint edges that aren’t supported. We match the product to the traffic and the movement flagging broken arrises before sealing.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix.

FAQs: Newbury

Must our site in Newbury stop work while the joints are done?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we will plan from there.

Do you take on work at healthcare sites like West Berkshire Community Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can you work while the building is occupied?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

Do your applicators hold CSCS cards?

Yes. We use CSCS-carded applicators.

What if the joint edges are damaged?

Broken arrises have to be put right before resealing, and we will point out where that’s the case. A bead on a broken edge soon lets go.

Do you cover Newbury?

Yes. Newbury falls within our area, and the simplest way to start is to speak to us on 01277 525 020 or send details through our quote form.

What sealant do you use in movement joints?

Whatever suits the joint and the specification. The quote states the sealant and its movement class so there are no surprises.

After the work

Keep the joints in good shape with a few simple steps:

  • Keep racking legs and heavy point loads off floor joints
  • Keep traffic off new joints until the cure time is up
  • Keep stones and debris out of open joint lines
  • Look over external and deck joints after a hard winter

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.

Joints sealed at the same time generally fail around the same time. 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.

Site staff or a sealant specialist?

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.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
