Expansion joint sealing near Townsend

Expansion joint sealing for commercial buildings in Townsend

Internal floor joints take trolleys, pallet trucks and forklifts. Unsupported edges break up under wheels, so the right filler or sealant for the traffic and movement matters. If the arrises are already broken, we will say so before sealing. If you have sealant peeling off one face of the joint and arrises breaking up along floor joints, we can put it right. A single leaking joint is often how a building in Townsend first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

In and around smaller places like Townsend, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

How the job changes by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. A semi-rigid filler is common in trafficked industrial floors and a flexible sealant where the joint moves more.

Warehouse floors and decks around Townsend

Central London is about 49 miles from Townsend. Warehousing clusters around the motorways that ring and radiate from London; their floors carry heavy traffic every shift. The South East is one of the drier parts of the UK. External slab and deck joints still need a dry, clean joint to seal, while winter salting gets into any joint left open.

Hospitals like Park Prewett Hospital, 4.5 miles to the south-east of Townsend, have multi-storey or surface car parks whose joints carry vehicles round the clock. Office parks like Scion Business Park (2.6 miles north of Townsend) have decks, ramps and clad elevations whose joints take movement every day.

Townsend is about 3 miles south-west of Tadley, in Hampshire. Across the RG26 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Townsend is one of 723 places we cover in Hampshire. We also cover Reading, around 13 miles from Townsend.

If you need expansion joint sealing in RG26, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Looking after the joints

Once the work is signed off, a little attention goes a long way:

  • Keep racking legs and heavy point loads off floor joints
  • Include every elevation and deck joint in periodic inspections
  • Keep traffic off new joints until the cure time is up
  • Note which joints were done, when, and with what

Grit is the slow enemy of a joint seal. Stones pressed into the bead by wheels or feet can puncture it and decks and floors suffer most. A routine sweep is the simplest protection.

Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint, well after the seal first opened. Resealing promptly prevents internal damage.

Townsend: questions and answers

Do you take on work at healthcare sites like Park Prewett Hospital?

Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you take on work at estates like Scion Business Park, close to Townsend?

Yes. Our area takes in Townsend and its surroundings, with estates and business parks such as Scion Business Park included. To start, just call the office on 01277 525 020 or email the details over with the unit, the joints involved and your access times.

Are you insured?

Yes. We are fully insured, and the certificate can go with your quote.

What if there’s asbestos in the old mastic?

Asbestos is possible in some older mastics, particularly in buildings from before 2000. Before we disturb old sealant in an older building, we ask to see the asbestos register or survey, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

What if the joint edges are damaged?

The edges have to be sound. If they’re damaged, we’ll say so before any sealing.

How long before the joints can be used?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.

Are expansion joints and movement joints the same thing?

The terms overlap a great deal. Both let materials grow and shrink with temperature, moisture and load, and the seal across it keeps water and debris out.

When to call us in Townsend

Three-sided adhesion is a common cause of early failure. Sealant fixed to the base and sides can’t flex, so it tears so backing is set before sealing.

Typical triggers for a call:

  • Water getting into the wall through a failed joint
  • Water dripping through deck or ramp joints
  • Hardened, cracked sealant on exposed facades
  • Arrises breaking up along floor joints

Schools like The Hurst School often have long brick elevations with movement joints that age quietly.

Questions to ask before you book

  • Which product they’ll use, and why it suits the joint
  • Their pre-qualification and accreditations
  • Who will actually carry out the work
  • Whether primer will be used where the manufacturer specifies it

Our contractor checklist

Site staff or a sealant specialist?

Redoing a failed joint normally costs more than getting it right at the outset, 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.

For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. Smaller jobs around Townsend can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
  6. We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.

Preparing the site

  • Move anything stored against the joints
  • Tell us your opening times and when work is allowed
  • Tell us what induction or permit system the site runs
