Common questions from Waterlooville clients

Would you work within a site like Queen Alexandra Hospital?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Is Dunsbury Hill Business Park, near Waterlooville, within your area?

Yes. We cover Waterlooville and the area around it, including industrial estates, business parks and retail parks such as Dunsbury Hill Business Park. Send details of the unit and the work through our quote form for a quick quote.

What information helps you price floor joint sealing?

Approximate metres of joint, photographs of typical and worst areas, and a floor plan let us give a quick quote. For larger floors, a site visit is often best so speak to us on 01277 525 020 or send details through our quote form to set one up.

When can forklifts run over new joint filler?

Each product has its own cure time and cooler floors take longer. Phasing is planned with that in mind.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Why has the filler pulled away from one side?

On newer slabs, the concrete keeps shrinking after the joints are filled and a stiff filler can separate down one side. A top-up normally puts it right.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Floor joint sealing in Waterlooville

Floor joint sealing for us covers warehouse aisles, loading bays, production halls, retail floors and showroom slabs. Pricing depends on the length of joint, how worn the edges are and when we can get in and the figure is fixed before work begins. If you have joint edges breaking up under truck wheels and joint fill separating from the concrete, we can put it right. Facilities teams, main contractors and managing agents in Waterlooville tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Movement joints on schools, offices and shops in towns like Waterlooville are easy to overlook until water gets in. A split or hardened joint lets rain into the wall, and it can no longer take up the movement.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

What we can’t put right

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • A failing floor coating, which is a flooring contractor’s job
  • Spalled arrises, which need an edge repair first
  • A floor that rocks at the joints, which needs a structural fix

Not sure which it is? You can phone 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Where we work in Waterlooville

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

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Traffic, movement and joints around Waterlooville

Waterlooville sits close to the coast, within about 3 miles. External movement joints in car parks, ramps and yards near the coast take salt and wind-driven rain on top of traffic, and edges left open tend to break up faster. Rainfall across the South East, Waterlooville included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

Hospitals like Queen Alexandra Hospital (2.8 miles south-west of Waterlooville) have multi-storey or surface car parks whose joints carry vehicles round the clock. For a school such as Hart Plain Junior School, playground and building joints can be done in the holidays. At places like Parklands Business Park, 1.7 miles to the north-west of Waterlooville, joints are sealed a section at a time so operations carry on.

Why deal with it now?

Some runs only need partial renewal or topping up. Where existing filler is well bonded and the gap beside it is small, a full strip-out isn’t always needed and the quote shows which approach suits each run. In a town like Waterlooville, a split, stained or mouldy joint is often the first thing visitors notice. Renewing it keeps the building looking cared for.

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Different surfaces, different methods

Flexible floor sealants

Polyurethane sealants suit floor joints with larger movement. They give less edge support than semi-rigid fillers, so they suit lighter traffic or movement joints.

Construction joints

Construction joints, sometimes called day joints, mark where one pour ended and the next began. They can move more than saw cuts and that shapes the choice of filler or sealant.

Diagnose, treat, sign off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. If you have more than one building in Waterlooville, they can often be done on the same visit. Give us your access times and we’ll fit the work in.

  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. 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. We fill each joint to depth and finish it flush so wheels roll straight across.
  6. The area is handed back once it has cured enough to take traffic.

Before we start on site

  • Confirm the product named in the specification
  • Clear stock, furniture or equipment away from the joints
  • Agree which areas must stay open

Maintenance after handover

Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:

  • Put loading bays at the top of the list
  • Walk the main routes and inspect joint lines on a regular cycle
  • Record damaged joints with a photo and a location
  • Tell us about strong cleaning chemicals before we quote

Normal floor cleaning is fine once the product has cured. If you use strong chemicals or hot-water washing, mention it when we quote so the product suits them.

Joints are easiest to look after when someone checks them regularly. A phased plan, worst routes first, spreads the work out and keeps on top of the rest.
