Floor joint sealing in Whippendell Bottom

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

What we are called out for in Whippendell Bottom

Soft sealant in a heavily trafficked joint gives the edges little support, so the concrete still breaks beside it. It can go the other way too: a stiff filler in a joint that keeps moving splits or comes away from the sides.

Things that typically lead to an enquiry:

  • A gap opening alongside old joint filler
  • Sealant pulled out along a truck route
  • Drivers complaining about joints on a route
  • Cracked and crumbling joint fill

A healthcare site such as Hemel Hempstead Hospital (to the north of Whippendell Bottom) depends on car parks, ramps and service yards whose joints take traffic all day.

What to look for in a quote

  • Whether old or failed sealant will be cut out, not overlaid
  • Their public liability cover
  • Which product they’ll use, and why it suits the joint
  • Health and safety accreditation such as CHAS

Joints that move: notes for Whippendell Bottom

At least three named trading, business or retail sites lie within about 3 miles of Whippendell Bottom. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. Rainfall across the South East, Whippendell Bottom included, is lower than in many parts of the UK. External slab and deck joints still need a dry, clean joint to seal, and gritting in cold spells finds its way into open joints.

At places like Apsley Industrial Estate, 1.8 miles north of Whippendell Bottom, joints are sealed a section at a time so operations carry on. On industrial estates such as Kings Park Industrial Estate, which lies east of Whippendell Bottom, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic.

Should maintenance staff do it?

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Whippendell Bottom: questions and answers

Do you cover business parks and estates near Whippendell Bottom, such as Kings Park Industrial Estate?

Yes. Our area takes in Whippendell Bottom and its surroundings, with estates and business parks such as Kings Park Industrial Estate included. A few photographs and the unit address let us price the work.

Is Whippendell Bottom off your patch?

No. Places such as Whippendell Bottom are covered as much as the big towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Will we need to close the floor?

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’ll plan around them.

When can forklifts run over new joint filler?

Cure times vary with the product and the conditions. We will give you a time for each zone when we agree the phasing.

Do you guarantee industrial floor joints?

Our workmanship carries a 12-month guarantee and the work is covered by public liability insurance.

Do you offer coloured sealant?

It depends on the product. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Expect fillers on young slabs to need a top-up
  • Sweep debris out of open joints until they can be filled
  • Start with the dock areas, where joints fail soonest
  • Make joint checks part of your floor inspections

On younger slabs, a fine line can open down one side of a filled joint as the concrete keeps shrinking. That is common and is usually dealt with by topping up once the slab has settled down in the majority of cases.

Edges tend to break slowly at first, then quickly. Once the first piece is out, wheels drop further and hit harder, so it pays to act at the first signs.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Which sealant the job calls for
  • Access and working height
  • The total length or number of joints
  • Joint width, depth and condition

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What to include in your enquiry

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

  • Rough lengths or quantities, or drawings if you have them
  • Photos of the joints, close up and from further back
  • The postcode of the building
  • Whether an asbestos survey exists

Need a figure for a tender or a budget? We will quote against your scope and drawings you can plan around. If you have questions first, call the office on 01277 525 020 or email the details over.

What we can’t put right

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • A failing floor coating, which is a flooring contractor’s job
  • Spalled arrises, which need an edge repair first
  • Unstable slabs moving under traffic

Not sure which it is? You can phone 01277 525 020 or send photos by email and we will tell you honestly.

Joints and surfaces we work on

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