Floor joint sealing in Locks Heath, done properly

A working floor can rarely be closed for days on end, so we phase the work aisle by aisle or bay by bay. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. The enquiries we see most involve sealant pulled out along a truck route and saw-cut joints left open and packed with grit, on forklift and pallet-truck routes, loading bays and saw-cut induced joints. Facilities teams, main contractors and managing agents in Locks Heath tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Small units near places like Locks Heath are often converted farm buildings with new concrete floors. Joints in those slabs need a product suited to whatever runs over them, from pallet trucks to foot traffic.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When to call us in Locks Heath

Older fills harden, shrink and crack with age, particularly where cleaning machines and traffic work it daily. At that point it neither holds the edges nor keeps debris out.

Clients normally get in touch after noticing one or more of the following:

  • Brittle joint filler breaking up
  • A rough ride across broken joints
  • Dock area joints that have failed first
  • Sealant pulled out along a truck route

At places like Kite's Croft Business Park, which lies south-east of Locks Heath, joints are sealed a section at a time so operations carry on.

What your quote should include

  • Which product they’ll use, and why it suits the joint
  • How they’ll work around occupants
  • The terms of the workmanship guarantee
  • Their pre-qualification and accreditations

How to choose a sealant contractor

Our process

Tell us your site hours and access windows and we’ll plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For a job in Locks Heath, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Old fill and packed debris come out until both faces are sound.
  4. We extract the dust and prime the faces if the product needs it.
  5. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

Getting the site ready

  • Agree which areas must stay open
  • Send asbestos survey details if the building is pre-2000
  • Confirm the product named in the specification

Joints that move: notes for Locks Heath

Locks Heath lies within about 2 miles of the sea. Open joints in coastal car parks and yards let in salt-laden water as well as grit, which is why split joints are worth sealing before the edges deteriorate. Locks Heath 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 where de-icing salt is spread in winter, open joints let it in.

Sites like Fareham Community Hospital (to the north-west of Locks Heath) carry ambulances, deliveries and visitors’ cars over their road and deck joints. Schools such as Park Gate Primary School have movement joints in their walls and floors that are easy to overlook.

Locks Heath is about 3 miles west of Fareham, in Hampshire. Commercial clients in Locks Heath use us for work on floor joints. Across Hampshire, 723 places are covered, including Locks Heath. Southampton is covered too, around 7 miles from Locks Heath.

Questions about Locks Heath

Does a coastal location like Locks Heath affect which sealant is used?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Will you take on work at estates like Park Gate Business Centre, close to Locks Heath?

Yes. Estates, retail parks and business parks around Locks Heath, Park Gate Business Centre among them, are all within reach. Photos and a short description are enough for a first look.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

Are your applicators CSCS-carded?

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

How soon can traffic go back on the floor?

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

Do you cover Locks Heath?

Yes. We take on work across Locks Heath, with one number for every area we cover.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Keeping the joints sound

After handover, a little attention goes a long way:

  • Photograph any joint that starts to chip
  • Treat loading bay joints first if they’re failing
  • Let us know what the floor is cleaned with
  • Sweep debris out of open joints until they can be filled

Walk the main truck routes every few months and look along the joint lines. Look for separation down one side, new chips in the arris and debris gathering and keep photographs so changes are easy to compare.

Grit in an open joint does damage every time a wheel crosses it. Getting it filled stops the damage before it becomes a repair.

How the quote is worked out

Quotes vary with the job. Expect it to depend on:

  • How much existing material needs removing
  • How much there is to seal
  • Distance, for remote addresses
  • Induction, permit and paperwork requirements

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.

Before you send an enquiry

To price the job accurately, we need to understand the site. Send us:

  • Drawings or a marked-up plan, if available
  • Whether the building will be occupied during the work
  • Whether an asbestos survey exists
  • Clear photos of the problem areas

Specifications, drawings and tender packages are welcome with any enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Why act early in Locks Heath

Every jolt over a broken joint passes into the truck, the load and the driver. Wheels and bearings wear faster and loads can shift, adding costs nobody plans for. A filled joint takes most of that out. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.
