Expansion joint sealing in Arborfield

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. Most enquiries involve joints where the bead has lost adhesion and water dripping through deck or ramp joints, across podiums and floor movement joints, brickwork movement joints and car park decks and ramps. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Arborfield, that means joint design, primers and backing rod as standard.

In and around smaller places like Arborfield, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

We stand by our work with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Common problems we fix in Arborfield

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Bonded on three faces, it can’t stretch evenly when the joint opens, which is why depth control matters.

Look out for the following:

  • Layers of sealant in a movement joint
  • Expansion joints filled with dirt and stones
  • Joints where the bead has lost adhesion
  • Torn sealant in brick or block movement joints

Large sites such as Wokingham Hospital, 3 miles east of Arborfield, have car parks, service roads and long elevations with movement joints in brick and panels.

Before you book anyone

  • What level of public liability insurance do they hold?
  • Whether old or failed sealant will be cut out, not overlaid
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What site paperwork they can supply

Questions to ask before you appoint anyone

Site staff or a sealant specialist?

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

FAQs: Arborfield

Is a smaller place like Arborfield outside your area?

No. Places such as Arborfield are covered as much as the big towns. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does your area include sites such as Thames Valley Science Park, near Arborfield?

Yes. Estates, retail parks and business parks around Arborfield, Thames Valley Science Park among them, are all within reach. A few photos and the unit address let us price the work.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Can you handle several sites?

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

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Are your applicators CSCS-carded?

Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.

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.

Diagnose, treat, sign off

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. Jobs in and around smaller places like Arborfield are typically planned as a single visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. We look at the joints, their width and how they’ve failed.
  2. Next, we fix a price and confirm the sealant we propose for the movement.
  3. We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
  6. We check every joint before sign-off, and the work carries our 12-month guarantee.

Before we start on site

Floors, slabs and movement joints in Arborfield

Arborfield sits in one of the drier corners of the country, the South East. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints. Arborfield lies roughly 36 miles out from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.

On a site such as Thames Valley Science Park, 1.4 miles to the north-west of Arborfield, the movement joints are in car park slabs, paving and building elevations. At places like Hogwood Lane Industrial Estate (2.1 miles south-east of Arborfield), joints are sealed a section at a time so operations carry on.

Arborfield is about 3 miles west of Wokingham, in Wokingham. Any commercial site in Arborfield is covered, for single jobs and planned programmes alike. Arborfield is one of 42 places in Wokingham on our list.

Anyone looking for expansion joint sealing in RG2 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee.

Why it’s worth doing now in Arborfield

Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use without shutting the whole car park. Tell us what has to stay open and we’ll plan around it. For buildings around smaller places like Arborfield, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote when you’re ready.

Why us?

  • Constructionline member for supplier checks
  • 12 months’ guarantee on every job
  • Failed material removed, not covered up
  • A fixed quote before work starts

What we can’t put right

Being straight saves everyone time. New sealant won’t cure:

  • Movement on a scale no sealant is meant to absorb
  • Proprietary pre-formed expansion joint systems
  • Joints too narrow for the movement, which need redesigning by the engineer

If you’re not sure, just call 01277 525 020 or email the details over and we will give you a straight answer.

Joints and surfaces we work on

  • Podiums and floor movement joints
