Floor joint sealing in Bracknell

Sometimes the concrete either side of a joint has already spalled. Filling against a crumbled arris won’t hold for long, so we will tell you if the joint edges need repairing first and explain how it affects the programme. We work on forklift and pallet-truck routes, saw-cut induced joints and retail and showroom floors, and what we are called in for most is old filler gone hard, cracked or loose and a rough ride across broken joints. A single leaking joint is often how a building in Bracknell first comes to us: we look at the rest while we’re there and tell you what we find.

Movement joints in a large town like Bracknell range from car park ramps and retail floors to the brick and panel joints on bigger buildings. Failed joints let water, grit and debris in, and the damage spreads from there.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Work for main contractors and building owners

Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

What sets the cost

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Any access equipment needed
  • Removal of failed or old sealant
  • Specialist products, such as fire-rated or hygienic sealants
  • Distance, for remote addresses

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you will have a fixed figure to work with.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Asbestos survey details if the building is older
  • The site address and postcode
  • The product your specification calls for
  • Drawings or a marked-up plan, if available

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Our process

Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. Bigger buildings in Bracknell are usually done in phases agreed with the site or facilities manager, keeping disruption low. Send drawings or photos and we’ll set out a phasing plan with the quote.

  1. First comes a walk of the floor to record joint sizes, broken edges and traffic routes.
  2. You get a fixed quote with the product and the phasing set out.
  3. Each joint is cleared of old fill and dirt and taken back to clean, sound edges.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. The chosen product is placed to its specified depth and trimmed level with the floor.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Getting the site ready

  • Have the specification and drawings to hand
  • Tell us your opening times and when work is allowed
  • Share the asbestos register for older buildings

Advice

Different surfaces, different methods

Semi-rigid joint fillers

Semi-rigid fillers are designed to support joint edges under hard wheels. They tolerate little movement, so they suit joints where most shrinkage has already happened.

Flexible floor sealants

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

Common problems we fix in Bracknell

Concrete slabs shrink as they dry out, and the saw cuts are there so it cracks in straight, controlled lines. As the panels contract, the joints widen so a filler put in early may separate along one side.

Most enquiries start with one or more of the following:

  • A rough ride across broken joints
  • Scruffy, dirty joint lines on a shop or showroom floor
  • Unfilled floor joints collecting dirt and grit
  • Old filler gone hard, cracked or loose

Phasing is what makes joint work possible on busy sites such as Longshot Lane Industrial Estate (1 mile west of Bracknell): one bay, aisle or car park row at a time.

How to choose a sealant contractor

Questions about Bracknell

Are the floor joints in an older unit in Bracknell worth resealing?

Usually, yes, as long as the joint edges are still sound. Resealing with the right filler or sealant for the traffic keeps grit out and protects the arrises, and we will tell you if the edges need repairing first.

Can you work on a hospital site such as Heatherwood Hospital?

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

What happens if the joint edges are damaged?

Edge condition is recorded when we look at the floor. Where they have broken away, we will tell you before quoting the filling, so nothing is filled that won’t hold.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Should floor joints be filled or sealed?

We decide joint by joint. Where hard wheels cross, a semi-rigid filler is typically right and perimeter or movement joints need flexibility. You’ll see the choice for each area in the quote.

Can the warehouse stay open while you work?

The work is phased. We work aisle by aisle or zone by zone so the rest of the floor stays in use. Tell us your site hours and access windows and we will plan around them.

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. It is normally dealt with by topping up.

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Record damaged joints with a photo and a location
  • Tell us about strong cleaning chemicals before we quote
  • Put loading bays at the top of the list
  • Stop forks and pallets being dragged across joints

Young concrete carries on shrinking, so some fillers part slightly from one face. It is a known trait of new floors and a later top-up deals with it.

While the concrete edges are intact, it’s a filling job. Once they have broken away, edge repair comes first and that takes longer and closes areas for longer.
