Expansion joint sealing for Beech sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

How a job runs

The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For work around Beech, we aim to finish in one visit, so photos and measurements up front really help. That way the right products come on the day.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces, flagging any broken edges that need repair before sealing.
  4. Closed-cell backing rod is set to depth, or bond-breaker tape in shallow joints.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Warn occupants and staff about the work
  • Point out parking and an unloading spot
  • For older buildings, check the asbestos register before work

Expansion joint sealing in Beech, done properly

Joint design counts for as much as the sealant itself. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises, and the bead is tooled so it grips the two faces alone. If you have hardened, cracked sealant on exposed facades and water getting into the wall through a failed joint, we can help, on precast concrete panel joints, car park decks and ramps and cladding panel joints alike. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Beech, that means joint design, primers and backing rod as standard.

Jobs around smaller places like Beech are planned so the whole job is done in one visit. Tell us the joint widths if you can, and what drives or walks over them.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Why deal with it now?

A torn seal left alone normally gets worse. Grit and water fill the gap and the material either side breaks up and the job grows to repairs as well as sealing. Acting at the first split keeps the cost down. Halls, stores and units around places like Beech may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Questions about Beech

Is Beech too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Do you cover business parks and estates near Beech, such as Kerridge Industrial Estate?

Yes, sites like Kerridge Industrial Estate are within our area, along with the rest of Beech. To start, just speak to us on 01277 525 020 or email us with the unit, the joints involved and your access times.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Can the sealant be colour-matched?

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

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Will you quote for a small job?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

How do we ask for a quote?

It works in four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photos and a postcode.

Expansion joint sealing in Beech: the local picture

Beech sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, while winter salting gets into any joint left open. The 3 miles around Beech take in at least three 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.

For a school such as Amery Hill School, playground and building joints can be done in the holidays. At places like Farringdon Business Park (2.3 miles south of Beech), joints are sealed a section at a time so operations carry on.

Beech is about 2 miles west of Alton, in Hampshire. If you are looking for expansion joint sealing in Beech, we can help. 723 places across Hampshire fall within our area, including Beech. We also cover Reading, around 21 miles from Beech.

Work on movement joints is covered throughout GU34, whatever the building.

Close to Beech, our area also takes in Thedden (1 mile north-west), Wivelrod (1 mile west), Bentworth (2 miles north-west), Holt End (2 miles west) and New Copse (2 miles west).

Surface by surface

Concrete and precast panel joints

Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.

Brickwork and blockwork joints

Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

When to call us in Beech

Most movement joint failures come down to the joint stretching further than the sealant can take. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. The same product in the same joint tends to fail again unless width and product are reviewed.

Common reasons buildings call us in:

  • Brittle, chalky sealant on external joints
  • Car park joints leaking onto vehicles below
  • New sealant over old, now failing
  • Torn sealant in brick or block movement joints

For an estate such as Alton Community Hospital, 1.2 miles east of Beech, the joints in ramps, decks and long building elevations all need attention over time.

What your quote should include

  • Their public liability cover
  • Can the work be phased to keep areas open?
  • How they handle RAMS and site documents
  • Is the sealant right for the movement and the substrate?
