Advice

About our floor joint sealing in Plummers Plain

It isn’t only heavy industry. Retail units, showrooms and trade counters have slab joints crossed by trolleys, footfall and cleaning machines, where a gappy, dirty joint looks untidy and snags castors. A flush, well-finished joint tidies the whole floor. We work on forklift and pallet-truck routes, joints along racking aisles and construction joints, and what we are called in for most is a gap opening alongside old joint filler and joint edges breaking up under truck wheels. A specialist sealant contractor works differently from a general builder: in Plummers Plain, that means joint design, primers and backing rod as standard.

Around smaller places such as Plummers Plain, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Wide or random cracking that suggests a structural issue
  • Unstable slabs moving under traffic
  • Damaged or worn floor coatings and screeds

If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think.

What we seal

  • Forklift and pallet-truck routes
  • Loading bays
  • Joints along racking aisles
  • Retail and showroom floors
  • Saw-cut induced joints
  • Construction joints

Keeping the joints sound

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

  • Plan for a top-up on newer floors
  • Record damaged joints with a photo and a location
  • Walk the main routes and inspect joint lines on a regular cycle
  • Ask drivers not to drag forks or pallets

Keep traffic off fresh joints until the time we give you and it pays to stick to it. In a busy building, barriers keep early traffic away.

Joints are easiest to look after when someone checks them regularly. A phased plan, worst routes first, spreads the work out so nothing is left to fail.

When to call us in Plummers Plain

Loading bay joints are exposed to wind, wet tyres and bigger temperature swings on top of the heaviest turning movements. They are often the first on a site to break down.

Any of the following is a good reason to get the joints checked over:

  • Old filler gone hard, cracked or loose
  • Joint fill separating from the concrete
  • A rough ride across broken joints
  • Dock area joints that have failed first

A healthcare site such as Horsham Hospital (4.4 miles north-west of Plummers Plain) depends on car parks, ramps and service yards whose joints take traffic all day.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • Whether old or failed sealant will be cut out, not overlaid
  • Which product they’ll use, and why it suits the joint
  • The terms of the workmanship guarantee

Choosing a commercial sealant contractor

Warehouse floors and decks around Plummers Plain

Central London is about 32 miles from Plummers Plain. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. Plummers Plain sits in one of the drier corners of the country, the South East. External joints still wait for dry conditions, while winter salting gets into any joint left open.

Schools such as Newells Preparatory School have movement joints in their walls and floors that are easy to overlook.

Work for main contractors and building owners

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.

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

Questions about Plummers Plain

Is a smaller place like Plummers Plain outside your area?

No. Places such as Plummers Plain are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Do we have to stop operations in Plummers Plain while the joints are sealed?

Rarely. Work is phased around your operations. Tell us which hours and entrances we can use and we’ll plan from there.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Will your applicators have CSCS cards?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Will we need to close the floor?

In the majority of cases, just the area being treated is coned off. Traffic returns to each zone once it has cured and the next zone follows.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited and a Constructionline member.

How long does a job like this take?

The duration is planned around your programme and the access we’re given. You’ll have an expected duration with the quote.

What happens if it’s left?

Dirt and spillage gather in open joints, out of reach of the floor cleaner. Where the floor is on show or needs to be kept clean, that is a problem. Filled joints are far simpler to keep clean. Older rural buildings around Plummers Plain move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
