Expansion joint sealing for commercial buildings in Hurstbourne Priors

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability, and depth is controlled using closed-cell backing rod, or bond-breaker tape in shallow joints. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1 and the bead bonds to the sides, never the back. We work on blockwork control joints, car park decks and ramps and brickwork movement joints, and the failures we’re asked to look at most are damp inside where a wall movement joint has failed and hardened, cracked sealant on exposed facades. For commercial sealant work in Hurstbourne Priors, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Smaller community and commercial buildings around Hurstbourne Priors have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

We stand behind the joints we seal: 12 months, guaranteed. It covers how we prepared and applied the sealant.

Diagnose, treat, sign off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and our waste is bagged and taken away as we go. For a building around Hurstbourne Priors, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We look at the joints, their width and how they’ve failed.
  2. You get a fixed quote with the product and its movement capability stated.
  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. We control the depth with backing rod or, in shallow joints, bond-breaker tape.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

Advice

Looking after the joints

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

  • Leave barriers in place until fresh joint sealant has cured
  • Keep product details with the building records for the next reseal
  • Put movement joints on the planned maintenance inspection round
  • Plan racking layouts so feet don’t land on a joint

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. Should you spot a problem, you can call 01277 525 020 or send photos by email and send a picture.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Catching it early keeps the water outside.

Expansion joint sealing in Hurstbourne Priors: the local picture

Hurstbourne Priors 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, and winter de-icing salt on car parks and ramps works into any open joint. At about 59 miles from central London, Hurstbourne Priors is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London.

Another example is Harewood Forest Industrial Estate, 2.4 miles south-west of Hurstbourne Priors, where floors and yards would be done in stages around the occupiers. For a school such as Testbourne Community School, playground and building joints can be done in the holidays.

What we’re called out for in Hurstbourne Priors

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.

Common reasons buildings call us in:

  • Expansion joints split through the centre of the bead
  • Joints packed with grit and debris
  • Hardened, cracked sealant on exposed facades
  • Sealant peeling off one face of the joint

On industrial estates such as Ardglen Industrial Estate, 2 miles north-east of Hurstbourne Priors, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

How to choose a sealant contractor

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Cracking or settlement that calls for an engineer’s assessment
  • Damaged metal nosings or cover plates over a joint

If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think before you book.

Joints and surfaces we work on

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

Site staff or a sealant specialist?

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

How the job changes by surface

Podium joints

Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.

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, with primer where specified.

FAQs: Hurstbourne Priors

Is Hurstbourne Priors too small for you to travel to?

Not at all. Hurstbourne Priors is within our area. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Is hospital work, at somewhere like Andover War Memorial Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. Each area is agreed with the ward or department and the estates team in advance.

How soon can the area be used again?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

Can you quote from photos?

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

Does the weather affect the work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

What will the job cost?

Every job gets its own fixed quote. To get one, speak to us on 01277 525 020 or send details through our quote form with a description of the work.

Do the joint edges need to be sound before sealing?

Sound edges are essential. Where they’ve broken up, we will tell you they need repairing first so you are not paying for a bead that won’t hold.
