How we handle floor joint sealing in Fernham

We have been sealing commercial joints since 2005. Our CSCS-carded applicators follow your site induction and rules, and we are CHAS accredited and a Constructionline member, with public liability insurance in place. Completed joints come with a 12-month guarantee on our workmanship. Site teams most often ask us about trucks and loads jolting over damaged joints and scruffy, dirty joint lines on a shop or showroom floor, on forklift and pallet-truck routes, loading bays and construction joints. Facilities teams, main contractors and managing agents in Fernham tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Around smaller places such as Fernham, 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.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why deal with it now?

An open joint is a modest filling job while its edges are sound. Left until they break, it needs an edge repair before any filling can start which means more downtime in that zone. Older rural buildings around Fernham move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Honest limits

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

  • Broken concrete either side of the joint
  • Damaged or worn floor coatings and screeds
  • A floor that rocks at the joints, which needs a structural fix

If you’re not sure, just ring 01277 525 020 or use the quote form and we will give you a straight answer.

Surfaces we seal

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

Different surfaces, different methods

Flexible floor sealants

Polyurethane floor sealants are available in a range of colours so ask if the colour matters.

Saw-cut induced joints

Open saw cuts collect grit and break at the arris. Filling them early keeps them tidy and protects the edges.

FAQs: Fernham

Is Fernham too far out for you?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Is hospital work, at somewhere like Faringdon Day Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we will confirm them with the quote.

What happens if old sealant might contain asbestos?

Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and work stops until any suspect material has been tested. Removing asbestos is a job for asbestos specialists, not us.

Why is there a gap next to the joint filler?

Young concrete carries on shrinking for a long time, so a semi-rigid filler can part from one face. A top-up normally puts it right.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Which sealant will you use?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked with your site contact. Where the sealant needs time to cure before use, we tell you and sign the area. Smaller jobs around Fernham can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. You get a fixed quote with the product and the phasing set out.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. We vacuum each run and prime it if the chosen product requires a primer.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. The area is handed back once it has cured enough to take traffic.

Getting the site ready

  • Point out any areas we must not close
  • Have the specification and drawings to hand
  • Flag any permit to work we will need

Maintenance after handover

Once the work is signed off, these steps help:

  • Mention any aggressive cleaning regime at quote stage
  • Stop forks and pallets being dragged across joints
  • Keep trucks off new joints until we say they’re ready
  • Photograph any joint that starts to chip

On younger slabs, a fine line can open down one side of a filled joint as the concrete keeps shrinking. That is common and is normally dealt with by topping up once the slab has settled down in the majority of cases.

Regular inspection catches failing fills before the edges go. We can quote a programme that starts with the busiest areas so nothing is left to fail.

Traffic, movement and joints around Fernham

At about 64 miles from central London, Fernham is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day. Fernham 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, while winter salting gets into any joint left open.

Parks like Faringdon Business Park, 1.4 miles to the north-west of Fernham, combine paved areas, car parks and building elevations, each with joints that move. Another example is Stanford in the Vale Business Park, which lies east of Fernham, where floors and yards would be done in stages around the occupiers. Hospital campuses such as Faringdon Day Hospital (to the north of Fernham) grow in stages, leaving movement joints wherever new blocks meet old.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we’ll confirm the paperwork you need with the quote.
