Expansion joint sealing for Brook sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Expansion joint sealing in Brook, 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, 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. If you’re dealing with joints packed with grit and debris and movement joints with split or torn sealant, we can put it right. Looking for mastic applicators who cover Brook? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Halls, schools and small commercial buildings near places like Brook have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

A 12-month guarantee applies to all our work in Kent. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we will arrange a return visit.

Common problems we fix in Brook

Sun, rain and frost age external movement joints. UV hardens the surface, and the sealant loses its ability to stretch, so it can’t follow the movement any more.

What tends to prompt an enquiry:

  • New sealant over old, now failing
  • Sealant peeling off one face of the joint
  • Leaks through car park deck joints onto the level below
  • Joints packed with grit and debris

Schools like Brook Community Primary School often have long brick elevations with movement joints that age quietly.

What to look for in a quote

  • The terms of the workmanship guarantee
  • Is the sealant right for the movement and the substrate?
  • Whether old or failed sealant will be cut out, not overlaid
  • Are they CHAS accredited or on Constructionline?

Our contractor checklist

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. For work around Brook, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  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, and we tell you if any edges need repairing first.
  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. We check every joint before sign-off, and the work carries our 12-month guarantee.

What we need from you

  • Send any specification or drawings in advance
  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed

Advice

When something else is needed

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

  • Proprietary pre-formed expansion joint systems
  • Concrete or masonry repairs along the arrises
  • Joints too narrow for the movement, which need redesigning by the engineer

If in doubt, call 01277 525 020 or email us and we’ll say what we think before you book.

Where we work in Brook

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

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

Slabs, ramps and loading bays in Brook

Brook 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 gritting in cold spells finds its way into open joints. Brook is about 51 miles from central London. The South East has large numbers of industrial estates and warehouses along the motorway corridors.

On a site such as Mersham-le-Hatch Business Village, 2.7 miles south of Brook, the movement joints are in car park slabs, paving and building elevations. Hospitals like WIlliam Harvey Hospital, 2.3 miles south-west of Brook, have multi-storey or surface car parks whose joints carry vehicles round the clock.

Brook is about 4 miles east of Ashford, in Kent. Brook sits inside our coverage and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. 931 places across Kent fall within our area, Brook among them. There’s a separate page for London, roughly 51 miles from Brook.

We take on movement joints across the TN25 postcode area. For a building on The Street, Troy Town Lane and Stonebridge or nearby, send details and we’ll quote for movement joints.

Questions about Brook

Is Brook too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Do you take on work at healthcare sites like WIlliam Harvey Hospital?

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.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Is colour matching possible?

In many cases, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.

Is movement joint sealing guaranteed?

A 12-month guarantee covers our workmanship and we hold public liability insurance. Keeping joints clear of debris helps them last.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

Do you hold CHAS accreditation?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Act on the first tear or lifting edge rather than waiting
  • Clear dirt from joint lines during routine cleaning
  • Keep traffic off new joints until the cure time is up
  • Brief car park operatives to protect joint lines during winter clearance

Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check and long before edges start to break. If anything looks wrong, speak to us on 01277 525 020 or use the quote form with photographs.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors. Resealing promptly prevents internal damage.

What the job involves on each surface

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

Podium joints

Podiums take foot traffic, planters and weather. A sealant suited to both traffic and exposure is used.
