Expansion joint sealing for businesses in Nyewood

Expansion joint sealing in Nyewood, done properly

Width, depth and product all have to work together. The joint has to be wide enough for the expected movement and the sealant’s movement capability. For wider joints, many sealant makers recommend a width-to-depth ratio, often around 2:1. The enquiries we see most involve torn sealant in brick or block movement joints and new sealant over old, now failing, on car park decks and ramps, brickwork movement joints and precast concrete panel joints. Most enquiries from Nyewood start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

Smaller community and commercial buildings around Nyewood have their own movement joints in walls and floors. They’re easily forgotten until water gets in or an edge breaks.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Slabs, ramps and loading bays in Nyewood

Rainfall across the South East, Nyewood included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints. Nyewood is about 48 miles from central London. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital, and their floor joints take forklift and pallet-truck traffic all day.

On industrial estates such as Upper Adhurst Industrial Park, which lies north-west of Nyewood, saw-cut floor joints, loading bay slabs and yard joints take the heaviest traffic. Hospital campuses such as Petersfield Community Hospital (3.7 miles west of Nyewood) grow in stages, leaving movement joints wherever new blocks meet old.

Nyewood is about 3 miles east of Petersfield, in West Sussex. Any commercial site in Nyewood is covered, whether it’s a single job or part of a planned programme. Nyewood is one of 373 places we cover in West Sussex for movement joints. Sites around Portsmouth have their own page, about 16 miles away.

Business premises anywhere in GU31 are within our area. If your building is just outside Nyewood, we cover East Harting (1 mile south), South Harting (2 miles south-west), Elsted (2 miles south-east), Dumpford (2 miles east) and Elsted Marsh (2 miles east). Nearby towns on our patch include Chichester (11 miles south), Portfield (11 miles south), East Wittering (15 miles south), Midhurst (5 miles east), Southbourne (10 miles south) and Westergate (13 miles south-east).

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Changing the joint layout or spacing of a structure

If in doubt, call 01277 525 020 or email a schedule or drawings and we will say what we think.

What we seal

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

Building owners, agents and FMs in Nyewood

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Nyewood can sit alongside others in a wider programme across West Sussex.

What the job involves on each surface

Concrete and precast panel joints

Concrete edges can be weak or carry release agents that stop adhesion. We prepare the faces thoroughly and prime where the maker calls for it and check the edges for soundness as we go.

Joints between different materials

Hybrid or MS polymer sealants bond to many substrates. The choice depends on the substrates and how much the joint moves, and confirm it in the quote.

Looking after the joints

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Leave barriers in place until fresh joint sealant has cured
  • Plan racking layouts so feet don’t land on a joint
  • Keep product details with the building records for the next reseal
  • Clear dirt from joint lines during routine cleaning

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead and a look at the joints after winter catches any damage.

An open joint fills with grit, and a joint full of grit can’t close. The edges then take the pressure and start to spall, turning a sealant job into a repair job. A sound seal keeps the joint working.

Questions about Nyewood

Can you work at a site such as Upper Adhurst Industrial Park, by Nyewood?

Yes. We cover Nyewood and the area around it, including industrial estates, business parks and retail parks such as Upper Adhurst Industrial Park. Send details of the unit and the work through our quote form for a quick quote.

Do you take on work at healthcare sites like Petersfield Community 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.

Can you seal joints in cold or wet weather?

Sealing onto a damp surface leads to adhesion failure. We agree a revised date with you.

What’s the quickest route to a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photos and a postcode.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

On site: what to expect

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work typically takes a few hours to several weeks, depending on how many metres of joint there are and how much old sealant or filler needs removing. For a building around Nyewood, tell us how to find it and who will meet us. Send that with the details and we’ll confirm the plan with the quote.

  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. Each area is handed back after its cure time, under our 12-month guarantee.

Before we start on site

  • Explain the parking and delivery arrangements
  • Point out any areas we must not close
  • Send asbestos survey details if the building is pre-2000

When to bring in a specialist

A short, simple internal joint is often within reach of a maintenance team. 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, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
