Expansion joint sealing in The Haven, done properly

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant. For wider joints, the width-to-depth ratio is often around 2:1, as the manufacturer advises and the bead bonds to the sides, never the back. We work on precast concrete panel joints, brickwork movement joints and blockwork control joints, and the failures we’re asked to look at most are leaks through car park deck joints onto the level below and sealant pulling off the joint face. Looking for mastic applicators who cover The Haven? We have been sealing commercial buildings since 2005.

Smaller community and commercial buildings around The Haven have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

FAQs: The Haven

Do you take on work at healthcare sites like Horsham Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Can you work at a site such as Spring Copse Business Park, by The Haven?

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

What causes movement joint sealant to fail?

It depends on how the sealant has let go: a split through the middle points to over-stretching, while peeling from one face points to preparation or primer. Broken edges are a third possibility.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Will you come and look before quoting?

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

What about RAMS and site documents?

Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

What do you charge?

Every job gets its own fixed quote. For yours, give us a call on 01277 525 020 or send photos by email with a description of the work.

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 usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases, and we clear our waste as we work. Jobs in and around smaller places like The Haven are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Before we start on site

  • For older buildings, check the asbestos register before work
  • Move anything stored against the joints
  • Flag any permit to work we will need

Quoting for work in The Haven

To price the job, we consider:

  • The product specified
  • Joint width, depth and condition
  • Removal of failed or old sealant
  • The site’s rules and procedures

There’s no price list, since every building and every scope is different. Call for a quote.

What we need to price the job

Whether it’s one area or a whole building, these details speed things up:

  • Any specification or named product
  • Photos of the joints, close up and from further back
  • Where the site is, with the postcode
  • Whether the building will be occupied during the work

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.

Common problems we fix in The Haven

When the movement exceeds the sealant’s capability, the bead tears. 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.

Things that typically lead to an enquiry:

  • Rain penetration at brick or block movement joints
  • Weathered movement joint sealant that no longer flexes
  • New sealant over old, now failing
  • Joints where the bead has lost adhesion

Parks like Spring Copse Business Park (to the east of The Haven) combine paved areas, car parks and building elevations, each with joints that move.

Warehouse floors and decks around The Haven

Rainfall across the South East, The Haven included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in. At about 34 miles from central London, The Haven is within reach of the capital. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift.

Large sites such as Horsham Hospital, 5.3 miles to the east of The Haven, have car parks, service roads and long elevations with movement joints in brick and panels. At places like The Old Brickworks Industrial Estate, 2.3 miles north of The Haven, joints are sealed a section at a time so operations carry on.

The Haven is about 3 miles north of Billingshurst, in West Sussex. We cover commercial sites throughout The Haven, for single jobs and planned programmes alike. Across West Sussex, 373 places are covered, including The Haven. For work in that direction, see our Brighton page, about 21 miles away.

What the job involves on each surface

Podium joints

Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond.

Looking after the joints

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

  • Keep scrapers and ploughs from dragging across joint sealant
  • Keep traffic off new joints until the cure time is up
  • Act on the first tear or lifting edge rather than waiting
  • Clear dirt from joint lines during routine cleaning

Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. A routine sweep is the simplest protection.

Joints sealed at the same time generally fail around the same time. Inspecting the whole run is worth the effort. We’ll tell you which movement joints need doing now and which can wait.
