When to call us in Puddle Dock

Oil, laitance, dust and old cleaning chemicals build up inside joints. If the faces aren’t taken back to clean concrete first the new filler can’t stay bonded.

Most enquiries start with one or more of the following:

  • Open saw cuts full of debris
  • Sealant pulled out along a truck route
  • Filler that has parted from one face
  • Loading bay joints breaking down

With Puddle Dock inside the ULEZ and kerb space scarce, we sort access and loading before the first day on site.

Before you book anyone

  • Who will actually carry out the work
  • Are they CHAS accredited or on Constructionline?
  • Proof of insurance
  • How joint depth will be controlled

Questions to ask before you appoint anyone

Floor joint sealing in Puddle Dock

Forklifts and pallet trucks are hard on open joints. Each crossing knocks the unsupported edge, and over time a neat cut turns into a ragged channel. A properly filled joint carries the wheel over and protects both arrises. It also smooths the route for drivers and stock. We work on retail and showroom floors, construction joints and loading bays, and what we are called in for most is old filler gone hard, cracked or loose and chipped and spalling edges along forklift routes. One point of contact handles commercial sealant work in Puddle Dock from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Puddle Dock means thinking about access, loading times and the ULEZ as well as the joints.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Building owners, agents and FMs in Puddle Dock

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.

What happens if it’s left?

Painting or coating straight over joints rarely lasts. The joints have to be filled or sealed as joints before or alongside any coating work. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote and we will explain how it’s made up.

What you get with us

  • Fixed quotes based on photos, drawings or a visit
  • Fully insured
  • CHAS accredited
  • One contact handling all your sites

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. All of Greater London is in the ULEZ, and kerbside space in Puddle Dock can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.

  1. We agree the traffic routes and phasing with your site team.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. The chosen filler or sealant goes in flush with the slab.
  5. You get a time for each zone to reopen.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Share the asbestos register for older buildings
  • Tell us your opening times and when work is allowed

What sealant work can’t fix

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

  • Uneven floors that need grinding or levelling
  • Worn screed or surface finishes
  • Spalled arrises, which need an edge repair first

Not sure which it is? You can phone 01277 525 020 or email a schedule or drawings and we will tell you honestly.

What we seal

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

Questions about Puddle Dock

Do you take on jobs in Puddle Dock where loading and access are tightly controlled?

Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.

Does your area include sites such as Childerditch Industrial Park, near Puddle Dock?

Yes. We cover Puddle Dock and the area around it, including industrial estates, business parks and retail parks such as Childerditch Industrial Park. Send details of the unit and the work through our quote form for a quick quote.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Which sealant will you use?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

When can forklifts run over new joint filler?

Cure times vary with the product and how cold the slab is. We’ll give you a time for each zone when we agree the phasing.

Can you fill joints where the arrises have spalled?

We check the edges as part of the survey. Damaged edges are flagged up front so the filling isn’t wasted.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Slabs, ramps and loading bays in Puddle Dock

Two named trading, business or retail sites lie within about 3 miles of Puddle Dock. Their warehouses, yards and car parks are exactly where joints take the most punishment. In London, decks, bays and service yards typically have to keep running, so joints are sealed in sections with each area handed back once cured.

Schools such as The James Oglethorpe Primary School have movement joints in their walls and floors that are easy to overlook. If you manage units on an estate such as Childerditch Industrial Park, 1.8 miles north-east of Puddle Dock, the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch.

Different surfaces, different methods

Construction joints

Day joints on busy routes are prone to edge damage. Movement and traffic are both checked before we decide what goes in.

Forklift and pallet-truck routes

Main aisles and cross routes carry the most wheel movements, so their joints wear fastest. A semi-rigid filler is common here because it supports the arrises under hard wheels.
