Floor joint sealing for commercial buildings in Walderslade

Sometimes the concrete either side of a joint has already spalled. Filling against a crumbled arris won’t hold for long, so if the edges need repair before any filling, we’ll say so and explain how it affects the programme. We work on joints along racking aisles, saw-cut induced joints and loading bays, and the failures we are asked to look at most are broken arrises where pallet trucks cross and scruffy, dirty joint lines on a shop or showroom floor. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Walderslade, that means joint design, primers and backing rod as standard.

In a smaller place such as Walderslade, floor and movement joints are often in agricultural and rural business units, schools and the odd small industrial yard. Their slabs and walls still need movement joints that work.

We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

What affects the price in Walderslade

Before we quote, we look at:

  • Which sealant the job calls for
  • Access and working height
  • How much there is to seal
  • Site requirements such as inductions and permits

The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • Where the site is, with the postcode
  • What the building is and how it’s used
  • Photos of the joints, close up and from further back
  • Any specification or named product

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Work for main contractors and building owners

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so the building keeps working while we do.

On site: what to expect

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, the joints are worked through in the order agreed with your site contact. Work in places the size of Walderslade is planned as a single visit where we can. Clear photos and measurements help us bring the right products.

  1. A floor survey records every joint, its edges and what crosses it.
  2. You receive a fixed quote showing products and phasing.
  3. Each joint is cut or routed back to clean, sound concrete.
  4. Dust is vacuumed out and primer applied where specified.
  5. Filler or sealant is placed to depth and finished flush.
  6. We hand each phase back when it can take traffic.

Before we start on site

  • Let building users know which areas are affected
  • Share the asbestos register for older buildings
  • Move anything stored against the joints

Related advice

Why deal with it now?

Every jolt over a broken joint passes into the truck, the load and the driver. That means extra wear on wheels and a rougher ride for staff, which nobody budgets for. A filled joint takes most of that out. Small buildings around Walderslade suffer from failed joints as much as large ones. Early resealing avoids the damage that follows a leak.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Common questions from Walderslade clients

Would you work within a site like Spire Alexandra Hospital?

Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.

Is Walderslade too small for you to travel to?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

What information helps you price floor joint sealing?

Use our quote form, or email photographs and a plan and tell us what runs on the floor. We then send a fixed quote that shows the products and zones.

What happens if the joint edges are damaged?

A filler needs sound edges to grip. If the arrises have spalled, we’ll say they need repair before filling, so you can decide how to proceed.

Is it normal for joint filler to separate?

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

How long do sealant joints last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

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.

Common problems we fix in Walderslade

A soft, flexible sealant on a forklift route can’t hold the arrises up, so the concrete still breaks beside it. The opposite mistake happens as well: a stiff filler in a joint that keeps moving splits or comes away from the sides.

Look out for the following:

  • Cracked and crumbling joint fill
  • Trucks and loads jolting over damaged joints
  • A gap opening alongside old joint filler
  • Sealant pulled out along a truck route

Schools such as Tunbury Primary School have movement joints in their walls and floors that are easy to overlook.

Questions to ask before you book

  • What the guarantee covers, and for how long
  • Their public liability cover
  • Can the work be phased to keep areas open?
  • Will CSCS-carded applicators be on site?

Our contractor checklist

Site staff or a sealant specialist?

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
