Floor joint sealing for commercial buildings in Catmore

A working floor can rarely be closed for days on end, so we phase the work aisle by aisle or bay by bay. Tell us your site hours and access windows and we’ll plan around them, with goods still moving in the areas we aren’t in. If you’re dealing with a gap opening alongside old joint filler and saw-cut joints left open and packed with grit, we can put it right, on forklift and pallet-truck routes, construction joints and joints along racking aisles alike. Searching for sealant specialists in Catmore? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Jobs around smaller places like Catmore are planned so the whole job is done in one visit. Note joint widths and the traffic that uses them, and we’ll take it from there.

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

Floor joint sealing in Catmore: the local picture

Catmore is about 54 miles from central London. The roads out of London are lined with trade parks and distribution sheds. Catmore is in the South East, one of the UK’s drier regions. External joints still wait for dry conditions, and winter de-icing salt on car parks and ramps works into any open joint.

In and around Catmore, the right filler or sealant for each joint depends on the traffic and the movement it takes.

Catmore is about 6 miles south-east of Wantage, in West Berkshire. Commercial clients in Catmore use us for work on floor joints. Across West Berkshire, 140 places are covered, Catmore among them. We also cover Reading, around 17 miles from Catmore.

Commercial sites across RG20 are covered. Nearby places we also cover include Farnborough (2 miles north-west), Brightwalton (2 miles west), Stanmore (2 miles south-east), Brightwalton Green (2 miles south-west) and West Ilsley (2 miles north-east) for floor joints. Further afield, our area takes in Newbury (8 miles south), Thatcham (9 miles south-east), Burghfield Common (15 miles south-east), Speenhamland (8 miles south), Hungerford (10 miles south-west) and Fords Farm (15 miles east).

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

Signs you need floor joint sealing in Catmore

Older fills harden, shrink and crack with age, particularly where cleaning machines and traffic work it daily. At that point it neither holds the edges nor keeps debris out.

What tends to prompt an enquiry:

  • Failing joints at loading bays and dock doors
  • Cracked and crumbling joint fill
  • Sealant pulled out along a truck route
  • A rough ride across broken joints

Around Catmore, open joints collect water and debris, and the arrises are the next to go.

What your quote should include

  • The named product and why it was chosen
  • Will failed sealant be removed rather than covered?
  • How they’ll work around occupants
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Our contractor checklist

Building owners, agents and FMs in Catmore

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first.

What we can’t put right

We check first that sealant really is the fix. It isn’t the answer for:

  • A floor that is out of level for the racking or trucks
  • Structural cracking in the slab
  • Slab panels that rock or move under load

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

Joints and surfaces we work on

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

Your questions answered

Must our site in Catmore stop work while the joints are done?

Usually not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

Is Catmore off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Which is better for warehouse joints, filler or sealant?

We decide joint by joint. Hard wheels need edge support, which points to a semi-rigid filler and perimeter or movement joints need flexibility. The quote sets out what goes where.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Why is there a gap next to the joint filler?

Separation usually comes from slab shrinkage, poor preparation or the wrong product. We look at which it is before recommending anything.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we will confirm it when we quote.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Catmore, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  1. We look at joint widths, edge condition and the traffic on each route.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. We remove failed material and packed debris until sound concrete is exposed on both faces.
  4. Dust is sucked out of the joint and a primer used if the product data sheet asks for one.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. We tell you when each zone can carry trucks again and move on to the next.

What we need from you

  • Share the asbestos register for older buildings
  • Explain the parking and delivery arrangements
  • Make sure the joints can be reached

What the job involves on each surface

Forklift and pallet-truck routes

Open route joints are hard on equipment and drivers. Filling them gives a smoother run and saves the edges.

Saw-cut induced joints

Sawn joints make up most of the joint length in a typical industrial floor. We clear them back to clean concrete and fill them to the depth the product calls for with a flush finish.
