Floor joint sealing for commercial buildings in Crowthorne

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. Our job is to put the right filler or sealant into them for the loads and the movement they see so the edges are held up and debris can’t pack in. We work on construction joints, forklift and pallet-truck routes and joints along racking aisles, and the failures we’re asked to look at most are unfilled floor joints collecting dirt and grit and loading bay joints breaking down. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Crowthorne, that means joint design, primers and backing rod as standard.

Joints in town car parks and service yards take tyres, de-icing salt and standing water. Resealing before the edges break up is far less disruptive than repairing them later.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

On site: what to expect

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Town-centre premises in Crowthorne may have limited parking, so tell us what’s nearby. Industrial and business units typically have yard or car park space.

  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.

Before we start on site

  • Agree which areas must stay open
  • Have the specification and drawings to hand
  • Point out parking and an unloading spot

What affects the price in Crowthorne

A fixed quote reflects the actual work. It allows for:

  • Quantities, in metres or numbers
  • Backing rod, priming and other preparation
  • Specialist products, such as fire-rated or hygienic sealants
  • How much existing material needs removing

The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.

Before you send an enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • The site address and postcode
  • Any specification or named product
  • Your programme or deadline
  • What the building is and how it’s used

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call 01277 525 020 or email us.

Doing it in-house

Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for 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.

Questions we are asked in Crowthorne

Does a site in Crowthorne have to shut while its joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. We agree the sequence and timings with you before we start.

Can you work at a site such as Wellington Business Park, by Crowthorne?

Yes. Estates, retail parks and business parks around Crowthorne, Wellington Business Park among them, are all within reach. To start, just call 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

What if there’s asbestos in the old mastic?

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

Which is better for warehouse joints, filler or sealant?

There isn’t one answer for a whole floor. Where hard wheels cross, a semi-rigid filler is typically right and perimeter or movement joints need flexibility. You’ll see the choice for each area in the quote.

Can you follow the specification on our project?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

Can you send site paperwork?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Do you seal on top of existing sealant?

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.

Maintenance after handover

A few simple habits keep the new joints working:

  • Clear packed debris from open joints regularly
  • Plan for a top-up on newer floors
  • Put loading bays at the top of the list
  • Ask drivers not to drag forks or pallets

Dragged forks and pallets gouge joints and edges alike. Even a well-filled joint can be damaged by steel scraping along it.

A broken joint on a main route is crossed by every truck on that route. Early treatment protects wheels, loads and drivers as much as the floor.

When it isn’t the sealant

Honesty saves time and money. Fresh joints won’t solve:

  • Uneven floors that need grinding or levelling
  • Broken concrete either side of the joint
  • Cracks across panels caused by settlement or overload

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly before you book.
