Expansion joint sealing for Bagnum sites

Expansion joint sealing for commercial buildings in Bagnum

We cover the full range of movement joints: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. Every one calls for a sealant picked for its movement, exposure and traffic, and we’ll confirm the choice in the quote. We work on car park decks and ramps, brickwork movement joints and blockwork control joints, and the usual reasons a site gets in touch are damp inside where a wall movement joint has failed and movement joints with split or torn sealant. A single leaking joint is often how a building in Bagnum first comes to us: we look at the rest while we’re there and tell you what we find.

In and around smaller places like Bagnum, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Building owners and contractors get the same cover: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Different surfaces, different methods

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. We pick the product for the materials and the movement, and confirm it in the quote.

Podium joints

On podiums, the joint can belong to a larger waterproofing detail. Where the specification calls for sealant, we reseal and flag it if the membrane looks like the source.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Waterproofing layers buried beneath the sealant
  • Movement on a scale no sealant is meant to absorb
  • Crumbling edges that would give a new bead nothing sound to grip

If in doubt, give us a call on 01277 525 020 or email drawings and photos and we will say what we think.

Where we work in Bagnum

  • Cladding panel joints
  • Podiums and floor movement joints
  • Precast concrete panel joints
  • Car park decks and ramps
  • Blockwork control joints
  • Brickwork movement joints

Commercial clients in Bagnum

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.

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.

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For a building around Bagnum, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the 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. Old sealant and filler are cut out and the joint faces cleaned back to sound material, 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. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification
  • Point out any areas we must not close

Warehouse floors and decks around Bagnum

At least three named trading, business or retail sites lie within about 3 miles of Bagnum. Their warehouses, yards and car parks are exactly where joints take the most punishment. Bagnum sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open.

Across sites such as Crow Arch Lane Industrial Estate, 1.5 miles north-west of Bagnum, floor and movement joints can be sealed in phases so units keep working. Schools such as Ringwood School have movement joints in their walls and floors that are easy to overlook. Hospitals like St Leonard's Hospital, 4.4 miles west of Bagnum, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Bagnum is about 2 miles south-east of Ringwood, in Hampshire. We cover commercial sites throughout Bagnum, whether it’s a single job or part of a planned programme. Bagnum is one of 723 places we cover in Hampshire. Our Southampton page has more on work in that area (17 miles or so).

Why it’s worth doing now in Bagnum

Combining joint work with other maintenance reduces set-up costs. Leaking joints need sealing now. We can split the scope into urgent and planned. For buildings around smaller places like Bagnum, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Resealing early avoids that.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Why appoint us

  • Colours confirmed for the specified product
  • One phone line for London, the South East and Scotland
  • Workmanship guaranteed for 12 months
  • Colours chosen to suit frames, cladding or finishes where possible

Common questions from Bagnum clients

Can you work at a site such as Platinum Jubilee Business Park, by Bagnum?

Yes. Estates, retail parks and business parks around Bagnum, Platinum Jubilee Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Is Bagnum too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Can you quote from photos?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Why do our movement joints keep failing?

Normally the joint is moving more than the sealant can take. That’s why we check width, depth and movement class before quoting.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Looking after the joints

Once the work is signed off, these steps help:

  • Put movement joints on the planned maintenance inspection round
  • Inspect exposed joints once the cold weather has passed
  • Reopen bays and walkways only after the stated cure time
  • Raise snow-clearing blades over deck joints where possible

On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead.

Unsupported floor joint edges spall under forklift and pallet-truck wheels. Damaged edges make the floor rough and wear wheels faster. Keeping the filler or sealant sound protects the floor.
