How we handle floor joint sealing in King's Somborne

Sometimes the concrete either side of a joint has already spalled. A filler laid against broken edges has nothing sound to grip, so if the edges need repair before any filling, we’ll say so and explain how it affects the programme. We work on joints along racking aisles, forklift and pallet-truck routes and retail and showroom floors, and the failures we’re asked to look at most are drivers complaining about joints on a route and a gap opening alongside old joint filler. A specialist sealant contractor works differently from a general builder: on jobs in King's Somborne, preparation and product choice get the time they need.

Jobs around smaller places like King's Somborne are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we’ll take it from there.

We stand by our work: 12 months, guaranteed. That covers our preparation and application.

Floor joint sealing around King's Somborne: points for this area

King's Somborne is about 67 miles from central London. The roads out of London are lined with trade parks and distribution sheds. King's Somborne is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and where de-icing salt is spread in winter, open joints let it in.

For an estate such as Romsey Community Hospital, 5.8 miles to the south of King's Somborne, the joints in ramps, decks and long building elevations all need attention over time. Schools such as King's Somborne Church of England Primary School have movement joints in their walls and floors that are easy to overlook.

King's Somborne is about 6 miles north of Romsey, in Hampshire. Any commercial site in King's Somborne is covered, whether it’s a single job or part of a planned programme.

Your questions answered

Must our site in King's Somborne stop work while the joints are done?

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

Is a hospital such as Romsey Community Hospital somewhere you can work?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you just go over the old sealant?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Which is better for warehouse joints, filler or sealant?

We decide joint by joint. Hard wheels need edge support, which points to a semi-rigid filler and perimeter or movement joints need flexibility. The quote sets out what goes where.

What if there’s asbestos in the old mastic?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

How long does a job like this take?

We plan the time on site around your programme and access. We’ll give you an estimate of time on site when we quote.

Diagnose, treat, sign off

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like King's Somborne are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  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. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

Getting the site ready

  • Tell us which areas need to stay in use
  • Make sure the joints can be reached

Related advice

Aftercare for building managers

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

  • Walk the main routes and inspect joint lines on a regular cycle
  • Let us know what the floor is cleaned with
  • Put loading bays at the top of the list
  • Stop forks and pallets being dragged across joints

We’ll give you a time before trucks can run over the new joints and it pays to stick to it. In a busy building, barriers keep early traffic away.

A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.

When it isn’t the sealant

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Slab panels that rock or move under load
  • Worn screed or surface finishes
  • Broken concrete either side of the joint

If in doubt, phone 01277 525 020 or email us and we’ll say what we think.

Joints and surfaces we work on

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

Why it’s worth doing now in King's Somborne

While the arrises are intact, filling a joint is straightforward. Wait until the edges have spalled and the concrete needs repairing before the joint can be filled, with longer closures to match. Older rural buildings around King's Somborne move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.

Pricing floor joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

Different surfaces, different methods

Semi-rigid joint fillers

Semi-rigid fillers are designed to support joint edges under hard wheels. They allow only small movement so timing matters on newer slabs.

Isolation joints at walls and columns

Where racking or plant sits near column joints, access is agreed before we start.

How the quote is worked out

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Access and working height
  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • The product specified

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Details that help us quote

Diagnosis starts before we arrive. Let us know:

  • The type of building and who uses it
  • Rough lengths or quantities, or drawings if you have them
  • The product your specification calls for
  • A wide shot and a close-up of the area

Let us know the site, the scope and your timescale, and a fixed quote will follow. The easiest way is to ring 01277 525 020 or email us.
