Expansion joint sealing in Knave's Ash, done properly
Internal floor joints take trolleys, pallet trucks and forklifts. Without a sound filler, joint edges chip and spall under load, so the right filler or sealant for the traffic and movement matters. We will tell you if the edges need repairing before sealing, and phased work keeps areas in use. Most enquiries involve joints where the bead has lost adhesion and new sealant over old, now failing, across podiums and floor movement joints, blockwork control joints and precast concrete panel joints. Searching for sealant specialists in Knave's Ash? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.
Jobs around smaller places like Knave's Ash are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered
Is Knave's Ash too small for you to travel to?
Not at all. Knave's Ash is within our area. We work across Greater London and the South East. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work on a hospital site such as Queen Victoria Memorial Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
When is resealing likely to be due?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Will your applicators have CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
What happens if it rains on the day?
The joint has to be dry, and the air and surface temperature inside the product’s limits. Frost, rain and condensation on steel or concrete can hold up external work, so we plan with the forecast in mind.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. These need a different solution:
- Crumbling edges that would give a new bead nothing sound to grip
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Damaged metal nosings or cover plates over a joint
If in doubt, speak to us on 01277 525 020 or use the quote form and we will say what we think before you book.

- Car park decks and ramps
- Precast concrete panel joints

How the quote is worked out
These are the things that shape the price:
- The total length or number of joints
- Which sealant the job calls for
- How accessible the joints are
- Backing rod, priming and other preparation
A quote for movement joints depends on how many there are, their condition and the access. Call for a quote.
What we need to price the job
The more we know, the firmer the quote. When you get in touch, include:
- Where the site is, with the postcode
- Access details, including height
- Whether an asbestos survey exists
- Any dates the work must fit around
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, give us a call on 01277 525 020 or use the quote form.
Do you need expansion joint sealing in Knave's Ash?
On trafficked joints, wheels and salts do the damage. Tyres and wheels press on the edges and the sealant, while de-icing salts and grit attack the seal. A sealant that isn’t trafficable won’t last there.
Look out for the following:
- Expansion joints filled with dirt and stones
- Brittle, chalky sealant on external joints
- Water dripping through deck or ramp joints
- Sealant pulling off the joint face
Phasing is what makes joint work possible on busy sites such as Canterbury Industrial Park (1.5 miles south-east of Knave's Ash): one bay, aisle or car park row at a time.
Questions to ask before you book
- How they’ll work around occupants
- Do they follow the manufacturer’s priming guidance?
- What the guarantee covers, and for how long
- Proof of insurance
Surface by surface
Concrete and precast panel joints
Concrete edges can be weak or carry release agents that stop adhesion. Proper cleaning and primer where specified give a sound bond.
Brickwork and blockwork joints
Mortar snots and debris in the joint stop it working. We clear the joint fully before sealing, and tell you if the joint looks too narrow for the movement.
On site: what to expect
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before the next one starts. Rural sites near Knave's Ash may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We assess the joints on site or from photos, noting widths and how each has failed.
- You receive a fixed quote stating the product and the movement it is rated for.
- Where areas have to stay open, we agree a phased sequence before starting.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- Point out parking and an unloading spot
- Let building users know which areas are affected
- For older buildings, check the asbestos register before work

Joints that move: notes for Knave's Ash

A campus such as University of Kent (to the south-west of Knave's Ash) has long runs of movement joint in its buildings, decks and paving. Schools such as Hoath Primary School have movement joints in their walls and floors that are easy to overlook.
