After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Astwick, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.
- We agree the traffic routes and phasing with your site team.
- Any joints with broken edges are flagged before work starts.
- We clear each run back to clean concrete.
- The chosen filler or sealant goes in flush with the slab.
- You get a time for each zone to reopen.
Preparing the site

How we handle floor joint sealing in Astwick
Most industrial slabs are divided into panels with saw cuts and day joints, and each joint line is a weak edge that wheels run over all day. We fill or seal them with a product matched to the traffic and the movement so the edges are held up and debris can’t pack in. Site teams most often ask us about a gap opening alongside old joint filler and old filler gone hard, cracked or loose, on forklift and pallet-truck routes, joints along racking aisles and construction joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Astwick, preparation and product choice get the time they need.
In and around smaller places like Astwick, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
Every job we finish is backed by a 12-month workmanship guarantee, in Astwick as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What the job involves on each surface
Saw-cut induced joints
Sawn joints make up most of the joint length in a typical industrial floor. Each one is cleaned out and filled to the specified depth, finishing flush with the slab.
Construction joints
Where a day joint crosses a truck route, its edges take heavy punishment. Movement and traffic are both checked before we decide what goes in.
What sets the cost
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Which sealant the job calls for
- Site requirements such as inductions and permits
- Quantities, in metres or numbers
- Phasing around occupants
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Details that help us quote
A few photos plus some basic facts will normally do. It helps to include:
- What the building is and how it’s used
- The asbestos register, for older buildings
- The postcode of the building
- Your programme or deadline
Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. The easiest way is to call 01277 525 020 or send photos by email.

Leave it or put it right?
Broken joints shake trucks, stock and operators alike. That means extra wear on wheels and a rougher ride for staff, adding costs nobody plans for. A filled joint takes most of that out. Older rural buildings around Astwick move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
Pricing floor joints depends on how many there are, their condition and the access. Call for a quote.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
When to call us in Astwick
An ageing filler or sealant can go brittle and split especially under daily scrubbing and traffic. At that point it neither holds the edges nor keeps debris out.
What tends to prompt an enquiry:
- Drivers complaining about joints on a route
- Sealant pulled out along a truck route
- Cracked and crumbling joint fill
- Failing joints at loading bays and dock doors
Across sites such as A1 Retail Park, 2.9 miles to the north of Astwick, floor and movement joints can be sealed in phases so units keep working.

Questions about Astwick
Do you take on work at healthcare sites like Fairfield Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Do you cover business parks and estates near Astwick, such as Stratton Business Park?
Yes, sites like Stratton Business Park are within our area, along with the rest of Astwick. A few photos and the unit address let us price the work.
How long will the new sealant last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
What if there’s asbestos in the old mastic?
Managing asbestos is the dutyholder’s responsibility, so we will ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.
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 before we start.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Can you send site paperwork?
Each site asks for different documents, so tell us what you need and we’ll confirm it when we quote.
