Floor joint sealing for Kemsley Street sites

Signs you need floor joint sealing in Kemsley Street

Concrete slabs shrink as they dry out, and the saw cuts are there so it cracks in straight, controlled lines. Each panel pulls back as it shrinks and the joints open up, and a filler placed early can part company with one face.

Look out for the following:

  • Joint edges breaking up under truck wheels
  • Filler that has parted from one face
  • Trucks and loads jolting over damaged joints
  • Loading bay joints breaking down

Retail parks like Hempstead Valley Shopping Centre, 0.9 miles north-west of Kemsley Street, have long runs of car park and yard joints taking daily traffic.

Questions to ask before you book

  • Can the work be phased to keep areas open?
  • Are they CHAS accredited or on Constructionline?
  • How they handle RAMS and site documents
  • Will CSCS-carded applicators be on site?

Questions to ask before you appoint anyone

How we handle floor joint sealing in Kemsley Street

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 will plan around them so the rest of the operation keeps going. We work on loading bays, construction joints and retail and showroom floors, and the failures we are asked to look at most are a rough ride across broken joints and untidy open joints in a retail unit. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Kemsley Street it comes down to the same thing: the right product in a properly prepared joint.

For a site near Kemsley Street, measurements and photographs up front mean one trip where possible, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What affects the price in Kemsley Street

There’s no standard rate for sealant work, since sites vary so much. What we look at:

  • Location, for remote and island sites
  • Which sealant the job calls for
  • The size and state of each joint
  • Phasing around occupants

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Details that help us quote

Diagnosis starts before we arrive. Tell us:

  • Any specification or named product
  • Access details, including height

Questions we’re asked in Kemsley Street

Do you take on work at healthcare sites like Spire Alexandra Hospital?

Yes. We work in healthcare settings as well as offices and schools. Each area is agreed with the ward or department and the estates team in advance.

Do you cover business parks and estates near Kemsley Street, such as Hempstead Valley Shopping Centre?

Yes. We cover Kemsley Street and the area around it, including industrial estates, business parks and retail parks such as Hempstead Valley Shopping Centre. To start, just call the office on 01277 525 020 or email us with the unit, the joints involved and your access times.

What happens if the joint edges are damaged?

Filling against broken edges doesn’t last. We’ll tell you if the joint edges need repairing first and set out how that affects the job.

What site paperwork can you supply?

Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

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, because fresh silicone will not bond with aged silicone.

How soon can traffic go back on the floor?

Cure times vary with the product and the conditions. You will get a reopening time for each area when we agree the phasing.

What happens if old sealant might contain asbestos?

The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Traffic, movement and joints around Kemsley Street

The 3 miles around Kemsley Street take in at least three named trading estates, business parks or retail parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic. Rainfall across the South East, Kemsley Street included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and where de-icing salt is spread in winter, open joints let it in.

University campuses such as University for the Creative Arts - Rochester, 4.5 miles to the north-west of Kemsley Street, have car parks, paved walkways and building elevations with movement joints. Hospital campuses such as Spire Alexandra Hospital (to the west of Kemsley Street) grow in stages, leaving movement joints wherever new blocks meet old.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Slab panels that rock or move under load
  • Level or flatness problems across the floor
  • A failing floor coating, which is a flooring contractor’s job

If in doubt, ring 01277 525 020 or send details through our quote form and we will say what we think.

Where we work in Kemsley Street

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

What the job involves on each surface

Flexible floor sealants

Flexible floor sealants come in several colours so ask if the colour matters.

Isolation joints at walls and columns

Joints around columns and along walls let the slab move without cracking against the structure. Something flexible normally suits them, not a stiff filler.

Diagnose, treat, sign off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. Where the sealant needs time to cure before use, we tell you and sign the area. For a building around Kemsley Street, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. First, the zones and order of work are agreed with you.
  2. We point out joints whose edges need repairing first.
  3. Failed material and debris are removed and the joint cleaned.
  4. We fill the joints with the agreed product, finished level.
  5. Each area is handed back when ready for traffic.

Preparing the site

  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs
  • For older buildings, check the asbestos register before work
