Floor joint sealing for commercial buildings in Cowplain

Open joints take a beating from forklift and pallet-truck wheels. Every pass chips at the bare concrete edge until a crisp saw cut becomes a wide, broken groove. A properly filled joint carries the wheel over and protects both arrises, which is kinder to trucks, loads and operators. We work on construction joints, joints along racking aisles and retail and showroom floors, and what we are called in for most is a gap opening alongside old joint filler and failing joints at loading bays and dock doors. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Cowplain, that means joint design, primers and backing rod as standard.

Around places the size of Cowplain, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.

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.

Floors, slabs and movement joints in Cowplain

Cowplain is about 58 miles from central London. Warehousing clusters around the motorways that ring and radiate from London. Cowplain has at least three named business or industrial parks inside a 3-mile radius. Sites like these are full of saw-cut floor joints, yard slabs and car park joints.

In a school such as Woodcroft Primary, movement joints in brick, block and hall floors tend to be forgotten until they leak. A healthcare site such as Havant War Memorial Hospital, 3.5 miles south-east of Cowplain, depends on car parks, ramps and service yards whose joints take traffic all day.

Your questions answered

Is a hospital such as Havant War Memorial 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.

Is Cowplain too small for you to travel to?

Not at all. Cowplain is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. If anything suspect turns up, we stop until it’s tested.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Do you use semi-rigid filler or flexible sealant on floor joints?

We decide joint by joint. Where hard wheels cross, a semi-rigid filler is normally right and perimeter or movement joints need flexibility. You will see the choice for each area in the quote.

Will your applicators have CSCS cards?

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

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What we are called out for in Cowplain

Left open, joints fill with grit, wrap and wood fragments. That debris is hard and levers at the edges as wheels pass so the arrises break sooner.

What tends to prompt an enquiry:

  • Saw-cut joints left open and packed with grit
  • Loading bay joints breaking down
  • Chipped and spalling edges along forklift routes
  • Trucks and loads jolting over damaged joints

Across sites such as Dunsbury Hill Business Park, 1.7 miles to the south-east of Cowplain, floor and movement joints can be sealed in phases so units keep working.

What to look for in a quote

  • Can the work be phased to keep areas open?
  • The named product and why it was chosen
  • Are they CHAS accredited or on Constructionline?
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

How a job runs

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. Then we strip out anything that has failed, prepare every joint and seal it. Several jobs near Cowplain can be grouped on one trip. Tell us your site hours and we will plan around them.

  1. First, the zones and order of work are agreed with you.
  2. We point out joints whose edges need repairing first.
  3. We clear each run back to clean concrete.
  4. We fill the joints with the agreed product, finished level.
  5. You get a time for each zone to reopen.

What we need from you

  • Tell us your opening times and when work is allowed
  • Agree which areas must stay open
  • Let building users know which areas are affected

What sets the cost

These are the things that shape the price:

  • The size and state of each joint
  • Access and working height
  • Whether the work must be split into stages
  • Site requirements such as inductions and permits

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.

What to include in your enquiry

A few photographs plus some basic facts will normally do. Please tell us:

  • Any specification or named product
  • Access details, including height
  • Photos of the joints, close up and from further back
  • When you need the work done

Pricing a project or setting a maintenance budget? We will quote against your scope and drawings you can plan around. For a chat about it beforehand, speak to us on 01277 525 020 or email drawings and photos.

When it isn’t the sealant

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is one of these:

  • Unstable slabs moving under traffic
  • A failing floor coating, which is a flooring contractor’s job
  • Broken concrete either side of the joint

If in doubt, call the office on 01277 525 020 or email the details over and we’ll say what we think.

Surfaces we seal

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

Site staff or a sealant specialist?

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

What the job involves on each surface

Isolation joints at walls and columns

We plan column and wall joints around racking and fixed plant so nothing has to move unexpectedly.

Retail and showroom floors

In retail, joints take trolleys, castors and cleaning machines rather than forklifts. We pick a filler or sealant to suit and the appearance is part of the brief.
