How we handle floor joint sealing in Crawley

Some joints reach us with their edges already broken. A filler laid against broken edges has nothing sound to grip, so we’ll tell you if the joint edges need repairing first and explain how it affects the programme. The enquiries we see most involve untidy open joints in a retail unit and drivers complaining about joints on a route, on construction joints, forklift and pallet-truck routes and saw-cut induced joints. Searching for sealant specialists in Crawley? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

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

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. For a building around Crawley, tell us how to find it and who will meet us. Send that with the details and we will confirm the plan with the quote.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. We extract the dust and prime the faces if the product needs it.
  5. The joint is filled to its specified depth and trimmed level.
  6. Zones reopen once cured and the work moves on.

Before we start on site

  • Explain the parking and delivery arrangements
  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints

Advice

Surface by surface

Forklift and pallet-truck routes

Trucks running over open joints wear wheels and shake loads. Filling them gives a smoother run and protects the floor.

Flexible floor sealants

Flexible floor sealants come in several colours so ask if the colour matters.

Aftercare for building managers

Cleaning and maintenance staff play a part too. Share these points with them:

  • Record damaged joints with a photo and a location
  • Stop forks and pallets being dragged across joints
  • Make joint checks part of your floor inspections
  • Clear packed debris from open joints regularly

If a joint we filled starts to break up within 12 months, tell us and we’ll arrange a look. After that, a check before your busiest period keeps small repairs small.

Treating joints while the arrises are sound keeps the work simple. Once they have broken away, edge repair comes first and that takes longer and closes areas for longer.

Crawley: questions and answers

Would you work within a site like Royal Hampshire County Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you take on work at estates like Beeches Industrial Park, close to Crawley?

Yes. Our area takes in Crawley and its surroundings, with estates and business parks such as Beeches Industrial Park included. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.

How long before trucks can use the joints?

The wait is set by the product’s cure time, and cold floors slow it down. Phasing is planned with that in mind.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Do you have public liability insurance?

Yes. We’re fully insured, including public liability cover.

How long does a typical visit take?

It depends on the scope, but the work normally takes a day or more, depending on the metres of joint and how many zones the floor is split into. For bigger or phased jobs, we will set out a timescale with the quote.

How the quote is worked out

Before we quote, we look at:

  • The site’s rules and procedures
  • Phasing around occupants
  • Which sealant the job calls for
  • The size and state of each joint

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What to include in your enquiry

The more we know, the firmer the quote. When you get in touch, include:

  • When you need the work done
  • Clear photographs of the problem areas
  • Drawings or a marked-up plan, if available
  • Access details, including height

To get a fixed quote, call the office on 01277 525 020 or send photos by email, telling us the site location and the nature of the job. Our quote form is another easy route.

Commercial clients in Crawley

Building owners and managing agents use us on everything from one building to a spread of sites around Crawley. Several sites can go on one quote, which keeps the paperwork simple.

CHAS accredited and a Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Slabs, ramps and loading bays in Crawley

Crawley sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. Less than 3 miles from Crawley there are two named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.

On industrial estates such as Beeches Industrial Park (1 mile south-east of Crawley), saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. University campuses such as University of Winchester, 4.6 miles south-east of Crawley, have car parks, paved walkways and building elevations with movement joints.

Crawley is about 5 miles north-west of Winchester, in Hampshire. Across the SO21 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. We work across 723 places in Hampshire, from busy centres to rural villages. For work in that direction, see our Southampton page (13 miles or so).

Work on floor joints is covered throughout SO21, for business premises of every kind. We also cover Worthy Down (3 miles east), South Wonston (3 miles east), Sutton Scotney (4 miles north-east), Barton Stacey (4 miles north) and Springvale (4 miles east) for floor joints. A short drive away, we cover Winchester (5 miles south-east), Eastleigh (10 miles south), Andover (8 miles north-west), Totton (14 miles south), Chandler's Ford (9 miles south) and Hedge End (14 miles south).

Around Crawley

In Crawley, that means premises near Fox And Hounds Public House. The closest station to Crawley is Winchester station, roughly 4.5 miles south-east. Nearby you will also find Winchester Castle (4.8 miles south-east) and Royal Hampshire County Hospital (4.5 miles south-east). Not far away are Winnall Moors.

What we are called out for in Crawley

Oil, laitance, dust and old cleaning chemicals build up inside joints. If the faces aren’t taken back to clean concrete first the new filler can’t stay bonded.

Look out for the following:

  • Saw-cut joints left open and packed with grit
  • Old filler gone hard, cracked or loose
  • A gap opening alongside old joint filler
  • Trucks and loads jolting over damaged joints

Phasing is what makes joint work possible on busy sites such as Balldown Business Centre (1.4 miles south of Crawley): one bay, aisle or car park row at a time.

Questions to ask before you book

  • Do they follow the manufacturer’s priming guidance?
  • How they’ll work around occupants
  • Health and safety accreditation such as CHAS
  • Is the sealant right for the movement and the substrate?
