Expansion joint sealing in Northfield

Width, depth and product all have to work together. Joint width must suit the movement and the movement class of the sealant while depth is limited by backing rod or, in shallow joints, a bond-breaker. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. If you have sealant peeling off one face of the joint and expansion joints split through the centre of the bead, we can put it right, whatever the surface. Searching for sealant specialists in Northfield? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around the edges of Scotland’s cities are warehouses, trade counters and distribution units, whose floor joints take forklift and pallet-truck traffic daily. The right filler or sealant, laid in phases, keeps them operating.

A 12-month guarantee applies to all our work. Should something we installed fail, speak to us on 01277 525 020 or email the details over and we’ll come back to it.

Traffic, movement and joints around Northfield

Northfield is in the east of Scotland, which is drier than the west. Cold winters and gritting are hard on any yard or deck joint left open. Sealing them in drier months limits winter damage. The 3 miles around Northfield 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.

Schools such as Northfield Academy have movement joints in their walls and floors that are easy to overlook. A healthcare site such as Woodend Hospital (to the south of Northfield) depends on car parks, ramps and service yards whose joints take traffic all day.

Northfield is about 2 miles north-west of Aberdeen, in Aberdeen. Anywhere in AB16, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Our Aberdeen coverage takes in 40 places, large and small.

We take on movement joints across the AB16 and AB21 postcode area, for business premises of every kind. Among the streets we cover are Tay Road, Quarry Road and Deveron Road. Just outside Northfield, we also work in Cummings Park (1 mile east), Mastrick (1 mile south), Bucksburn (1 mile north-west), Summerhill (1 mile south) and Cornhill (1 mile south-east). Nearby towns on our patch include Ferryhill (3 miles south-east), New Aberdeen (3 miles south-east), Dyce (3 miles north-west), Cults (3 miles south), Braeside (3 miles south) and Cove Bay (5 miles south-east).

From enquiry to sign-off

Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then handed back before we move to the next. University, hospital and office estates in Scotland’s cities have their own permits, inductions and sign-in rules. Tell us the rules and we will work to them.

  1. Photos, joint lengths and drawings come to us, or we visit.
  2. Joint widths and expected movement are checked against what the sealant can take.
  3. Old sealant and debris are cut out of every joint.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Each area is handed back after its cure time, under our 12-month guarantee.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Let building users know which areas are affected
  • Tell us your opening times and when work is allowed

How the job changes by surface

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. The right filler or sealant for the traffic and movement protects them flagging broken arrises before sealing.

Brickwork and blockwork joints

Brick and block edges need careful preparation. We clean them back to sound material and prime where the manufacturer specifies, then seal and tool the joint.

Should maintenance staff do it?

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.

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

Leave it or put it right?

On a car park, resealing joints in phases keeps the deck open. Work can be planned so parts of the deck stay open, compared with a full closure. Tell us what has to stay open and we will plan around it. Scottish city buildings take plenty of rain, so a split or hardened joint lets water into the wall. Renewing them early protects the fabric.

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Honest limits

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Movement on a scale no sealant is meant to absorb
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Broken or spalled joint edges, which need repairing before any sealant goes in

If you’re not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer.

Surfaces we seal

  • Brickwork movement joints
  • Podiums and floor movement joints
  • Precast concrete panel joints
  • Blockwork control joints
  • Cladding panel joints
  • Car park decks and ramps

Common questions from Northfield clients

Is hospital work, at somewhere like Woodend Hospital, something you do?

Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.

Is Twin Spires Business Park, near Northfield, within your area?

Yes. Estates, retail parks and business parks around Northfield, Twin Spires Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Is it fine to apply new sealant on top of old?

No. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

Do the joint edges need to be sound before sealing?

Sound edges are essential. If they’re damaged, we’ll say so before any sealing, so the new seal has something to grip.

Do you guarantee expansion joint work?

The 12-month guarantee applies to the workmanship. Tell us right away if a joint we sealed gives trouble in that time.

Do you use silicone or polyurethane in movement joints?

We choose a sealant with a movement capability that suits the joint, classified under BS EN ISO 11600. Where two different materials meet, a hybrid sealant can be the better choice.

Does the weather affect joint sealing?

Sealing onto a damp surface leads to adhesion failure, so external work waits for suitable conditions. We agree a revised date with you.

Do you need expansion joint sealing in Northfield?

Most movement joint failures come down to the joint stretching further than the sealant can take. Cohesive failure, a split through the centre, normally means the joint or product wasn’t right for the movement. Resealing like for like often fails the same way.

Most enquiries start with one or more of the following:

  • Expansion joints filled with dirt and stones
  • Arrises breaking up along floor joints
  • Layers of sealant in a movement joint
  • Water getting into the wall through a failed joint

For buildings at a park such as Twin Spires Business Park, 0.7 miles north of Northfield, brick and panel movement joints are easy to forget until one leaks.

What your quote should include

  • Whether old or failed sealant will be cut out, not overlaid
  • Their pre-qualification and accreditations
  • Can the work be phased to keep areas open?
  • Do they follow the manufacturer’s priming guidance?
