Expansion joint sealing for Sarisbury sites

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

Maintenance after handover

Once the work is signed off, a little attention goes a long way:

  • Plan racking layouts so feet don’t land on a joint
  • Raise snow-clearing blades over deck joints where possible
  • Reopen bays and walkways only after the stated cure time
  • Record the sealant used and the date in the O&M file

Fresh joint sealant needs its full cure time before it takes traffic or water. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. A sound seal keeps the joint working.

About our expansion joint sealing in Sarisbury

Width, depth and product all have to work together. 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, and the bead is tooled so it grips the two faces alone. The enquiries we see most involve debris jammed in movement joints and joints where the bead has lost adhesion, across podiums and floor movement joints, cladding panel joints and precast concrete panel joints. Facilities teams, main contractors and managing agents in Sarisbury tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Small units near places like Sarisbury are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Surface by surface

Brickwork and blockwork joints

Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it before the bead goes in.

Car park decks and ramps

Car park joints are some of the hardest-working joints in any building. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.

Work for main contractors and building owners

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sarisbury can form part of a wider programme.

Expansion joint sealing in Sarisbury: the local picture

Sarisbury is within about 2 miles of the coast. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, which is why split joints are worth sealing before the edges deteriorate. Sarisbury is about 67 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift.

Schools such as Sarisbury Church of England Junior School have movement joints in their walls and floors that are easy to overlook. At places like Solent Business Park, which lies east of Sarisbury, joints are sealed a section at a time so operations carry on.

Sarisbury is about 3 miles south of Hedge End, in Hampshire. Commercial clients in Sarisbury use us for work on movement joints, as part of our coverage of Hampshire. Across Hampshire, 723 places are covered, including Sarisbury. Our Southampton page has more on work in that area (6 miles or so).

Signs you need expansion joint sealing in Sarisbury

Weathering wears down sealant on exposed elevations and decks. UV hardens the surface, and the sealant loses its ability to stretch and opens at the next temperature swing.

Site and facilities staff are often the first to spot these:

  • Sealant pulling off the joint face
  • Chipped joint edges on forklift routes
  • Hardened, cracked sealant on exposed facades
  • New sealant over old, now failing

Business parks such as Park Gate Business Centre (0.7 miles east of Sarisbury) have car parks, paved areas and long brick and panel elevations, all with movement joints.

Choosing a commercial sealant contractor

Sarisbury: questions and answers

Is Sarisbury too small for you to travel to?

Not at all. Sarisbury is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Does the sea air around Sarisbury change the choice of sealant?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

How long before the joints can be used?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Can the sealant be colour-matched?

That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.

How do you deal with asbestos in old sealant?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. 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.

What if the joint edges are damaged?

Sealant needs sound faces to bond to, so we’ll tell you if the edges need repairing before sealing. We flag it at the quote stage where we can see it.

Will you come and look before quoting?

Many jobs can be quoted from photos, drawings or a joint schedule. If the job needs a look first, we will arrange a visit.

Cost factors for movement joints

We price every job individually. The main factors are:

  • How much existing material needs removing
  • Which sealant the job calls for
  • Induction, permit and paperwork requirements
  • The size and state of each joint

Pricing movement joints depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • The asbestos register, for older buildings
  • Drawings or a marked-up plan, if available
  • How the joints are reached, and at what height
  • What the building is and how it’s used

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call 01277 525 020 or send photos by email if you’d rather talk the job through.

From enquiry to sign-off

The first thing on site is a walk round with your contact, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a job in Sarisbury, the main thing is a clear picture of the work. You will then get a fixed price for the work.

  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. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid 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

  • Arrange parking or a loading space
  • Send your site hours and access windows
  • Send any specification or drawings in advance

Quotes
