Expansion joint sealing across Radley Green

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Avoid parking heavy plant or pallets on joint lines
  • Put movement joints on the planned maintenance inspection round
  • Report split or peeling joint sealant early
  • Reopen bays and walkways only after the stated cure time

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’ll tell you when each bay or area can reopen. Keeping the area coned off until then avoids tyre marks and damage.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We can suggest an order, worst joints first.

Expansion joint sealing in Radley Green, done properly

Joint design counts for as much as the sealant itself. The joint has to be wide enough for the expected movement and the sealant’s movement capability. 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. The enquiries we see most involve joints where the bead has lost adhesion and spalled or broken joint edges in floors and decks, on brickwork movement joints, car park decks and ramps and podiums and floor movement joints. A specialist sealant contractor works differently from a general builder: in Radley Green, that means joint design, primers and backing rod as standard.

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

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Signs you need expansion joint sealing in Radley Green

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, so we check width and movement before quoting.

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

  • Water dripping through deck or ramp joints
  • Arrises breaking up along floor joints
  • Expansion joints split through the centre of the bead
  • Joints where the bead has lost adhesion

For estates staff at a university like Writtle University College Cow Watering Campus, 2.6 miles east of Radley Green, building and paving joints are part of the planned maintenance list.

Choosing a commercial sealant contractor

Radley Green: questions and answers

Can you take on a job at a hospital such as Chelmsford and Essex Hospital?

Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Radley Green too far out for you?

Not at all. Radley Green 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.

Can one quote cover more than one building?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

How do you choose the sealant?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, as many construction sites ask for.

How long will the joint resealing take?

That depends on joint lengths, widths, access and how much old sealant or filler needs removing. As a guide, it usually takes a day or so for a modest run of joints, and longer where decks, ramps or floors are done in phases.

From enquiry to sign-off

Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. For work around Radley Green, we aim to finish in one visit, so we ask for photos 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. 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. 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.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed

Surface by surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it, so the new seal holds.

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. A trafficable sealant suited to the movement goes in with bays done in phases so the car park keeps running.

What happens if it’s left?

Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. Older rural buildings around Radley Green move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Why appoint us

  • Matching to RAL references, product permitting
  • Colours confirmed for the specified product
  • Fixed quotes based on photos, drawings or a visit
  • CSCS-carded applicators
