Expansion joint sealing for commercial buildings in Germiston

Joints in car park decks and ramps are among the hardest-working in any building. Tyres load the edges, and de-icing salts and water work into any gap, so failed seals soon lead to leaks onto the level below and broken edges. We reseal deck and ramp joints with a trafficable sealant chosen for the movement. We work on brickwork movement joints, car park decks and ramps and blockwork control joints, and the usual reasons a site gets in touch are previous reseals laid over old sealant and water dripping through deck or ramp joints. Whoever orders the work in Germiston, the brief is typically the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Weather windows decide external joint work around a place like Germiston: sealant needs a dry joint and a temperature within its range. Internal floors can be done whenever suits the site.

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.

Slabs, ramps and loading bays in Germiston

With the shore within about 2 miles, Germiston counts as a coastal location. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, which is why split joints are worth sealing before the edges deteriorate. Germiston is in the east of Scotland, which is drier than the west. Frost and de-icing salt still find their way into open external joints. Autumn is a sensible time to seal them.

Around Germiston, each joint gets a filler or sealant matched to what crosses it and how much it moves. A joint near Germiston that has lost its sealant lets in water and grit, and the edges suffer next.

Germiston is about 7 miles west of Kirkwall, in the Orkney Islands. Germiston sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. Our the Orkney Islands coverage takes in 51 places, from busy centres to rural villages.

Business premises anywhere in KW16 are within our area for movement joints. We also cover Heddle (1 mile north-east), Finstown (2 miles north-east), Grimbister (2 miles north-east), Stenness (2 miles west) and Clouston (3 miles west). For island and remote sites, travel and materials need planning ahead.

Leave it or put it right?

Re-sealing with the same product that failed is often a false economy. A higher movement class, or a design change by the engineer, may be needed, and we will say so before quoting. Renewing every failing joint on one visit is the sensible approach for a place like Germiston. Send photos and we’ll quote for everything together.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote and we’ll explain how it’s made up.

Take a look at what affects the cost and how we’re accredited.

Surface by surface

Internal floor movement joints

Floor joints include saw-cut joints and construction joints. Trafficked floor joints often get a semi-rigid filler, with a flexible sealant where movement is larger.

Joints between different materials

Different materials meeting at a joint rarely move in step. The product must bond to both substrates and cope with the movement priming where the maker calls for it.

Your questions answered

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

In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.

Does a coastal location like Germiston affect which sealant is used?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We choose the product for the exposure, prime where the manufacturer requires it and size the joint for its movement.

Do you cover Germiston?

Yes. Sites across Germiston are covered, and the same phone number covers every area.

What sealant do you use in movement joints?

The specification comes first, then the joint’s movement and exposure. We name the proposed product in the quote.

Do you reseal car park expansion joints?

Yes. Deck and ramp joints are resealed with a trafficable sealant chosen for the movement, and phased work can be planned so parts of the car park stay in use.

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

No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

What we can’t put right

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Joints too narrow for the movement, which need redesigning by the engineer
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
  • Proprietary pre-formed expansion joint systems

If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Joints and surfaces we work on

  • Brickwork movement joints
  • Blockwork control joints
  • Precast concrete panel joints

On site: what to expect

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. Where we can, we combine work around Germiston with other jobs nearby. Tell us how flexible your dates are.

  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, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. A sealant suited to the movement and traffic is laid to depth and tooled.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Agree which areas must stay open
  • Share the asbestos register for older buildings
  • Have the specification and drawings to hand

Related advice

After the work

After handover, a little attention goes a long way:

  • Keep stones and debris out of open joint lines
  • Plan racking layouts so feet don’t land on a joint
  • Report split or peeling joint sealant early
  • Note which joints were done, when, and with what

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears, especially on car park decks and warehouse floors. Regular sweeping keeps joint lines clear.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.
