Expansion joint sealing in Harbridge

Joints in car park decks and ramps are among the hardest-working in any building. Wheel loads, grit and de-icing salts attack the seal and the concrete either side. A sealant suited to traffic and the expected movement goes in, phasing bays so the car park can stay in use. If you have leaks through car park deck joints onto the level below and new sealant over old, now failing, we can put it right. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Harbridge, preparation and product choice get the time they need.

Halls, schools and small commercial buildings near places like Harbridge have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

On site: what to expect

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. Rural sites near Harbridge may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Share your working hours and any access restrictions
  • Arrange parking or a loading space
  • Let building users know which areas are affected

Expansion joint sealing around Harbridge: how the place shapes the job

Harbridge is in the South East, one of the UK’s drier regions. Even so, yard and car park joints are only sealed when they’re dry and clean, and winter de-icing salt on car parks and ramps works into any open joint. The 3 miles around Harbridge 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.

Phasing is what makes joint work possible on busy sites such as Fordingbridge Business Park (2.7 miles north of Harbridge): one bay, aisle or car park row at a time. Sites like Fordingbridge Hospital (to the north of Harbridge) carry ambulances, deliveries and visitors’ cars over their road and deck joints.

Harbridge is about 3 miles north of Ringwood, in Hampshire. We cover Harbridge, with the same fixed quotes and 12-month guarantee as everywhere else. Across Hampshire, 723 places are covered, including Harbridge. Our Southampton page has more on work in that area, about 18 miles away.

We cover the BH24 postcode districts. For a building on Kent Lane and Churchfield Lane or nearby, send details and we’ll quote for movement joints. Just outside Harbridge, we also work in Ibsley (1 mile south-east), Mockbeggar (1 mile east), Ellingham (1 mile south), South Gorley (1 mile east) and Rockford (2 miles south-east). Bigger towns within reach include Totton (13 miles east), Lymington (14 miles south-east), Romsey (15 miles north-east), New Milton (11 miles south-east), Ringwood (3 miles south) and Barton on Sea (12 miles south-east).

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is one of these:

  • Waterproofing layers buried beneath the sealant
  • Cracking or settlement that calls for an engineer’s assessment
  • A joint that has to be widened or re-detailed before it can work

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

What we seal

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

Surface by surface

Concrete and precast panel joints

Joints between precast panels open and close with temperature and loading. We use a sealant classed for the movement, laid over backing to depth.

Podium joints

Podium joints often sit within a waterproofing system. We reseal the joint where sealant is the specified fix.

Common questions from Harbridge clients

Is a smaller place like Harbridge outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Do you cover business parks and estates near Harbridge, such as Headlands Business Park?

Yes. Estates, retail parks and business parks around Harbridge, Headlands Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Can a joint be sealed if the edges are broken?

Broken arrises have to be put right before resealing and we will flag every length affected. A bead on a broken edge soon lets go.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

What exactly is a movement joint?

It’s a deliberate gap that lets the structure move without cracking. Many people call it an expansion joint, and either way it needs a sound seal.

What happens if it rains on the day?

Weather matters for any external joint because a damp or frozen joint won’t take a proper bond. Indoor joints can usually carry on regardless.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Owners, agents and contractors

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. We work to your programme, your specification and your site rules.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

Do you need expansion joint sealing in Harbridge?

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

It’s worth sending us details if you spot any of the following:

  • Joints packed with grit and debris
  • Brittle, chalky sealant on external joints
  • Sealant pulling off the joint face
  • Arrises breaking up along floor joints

Business parks such as Headlands Business Park, 2.2 miles south of Harbridge, have car parks, paved areas and long brick and panel elevations, all with movement joints.

What to look for in a quote

  • What level of public liability insurance do they hold?
  • Whether old or failed sealant will be cut out, not overlaid
  • Will CSCS-carded applicators be on site?
  • Is the sealant right for the movement and the substrate?
