About our expansion joint sealing in Marshborough

Few joints take as much punishment as those in a car park. Wheel loads, grit and de-icing salts attack the seal and the concrete either side; water dripping through to the deck below is often the first sign. We reseal deck and ramp joints with a trafficable sealant chosen for the movement and the work can be phased so parts of the car park stay open. If you’re dealing with torn sealant in brick or block movement joints and sealant peeling off one face of the joint, we can help, on precast concrete panel joints, podiums and floor movement joints and blockwork control joints alike. Searching for sealant specialists in Marshborough? We’ve been sealing commercial buildings since 2005.

Around smaller places such as Marshborough, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Common questions from Marshborough clients

Do we have to stop operations in Marshborough while the joints are sealed?

In the majority of cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. Tell us which hours and entrances we can use and we’ll plan from there.

Does your area include sites such as Birnham Farm Business Centre, near Marshborough?

Yes, sites like Birnham Farm Business Centre are within our area, along with the rest of Marshborough. A few photos and the unit address let us price the work.

What’s the quickest route to a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photos and a postcode.

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.

Do you work to architects’ specifications?

Yes. Include it with the drawings when you ask for a quote, and we’ll price the work to it, flagging anything that needs clarifying.

How long does movement joint sealing take?

Allow a short visit for a handful of joints, or several days or more for a car park deck or long runs of facade joints. Timings are set out in the quote.

How long before the joints can be used?

We will confirm how long the chosen product needs to cure.

Maintenance after handover

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Keep product details with the building records for the next reseal
  • Reopen bays and walkways only after the stated cure time
  • Avoid parking heavy plant or pallets on joint lines
  • Keep stones and debris out of open joint lines

Keep wheels, feet and water off new joints until the sealant has cured. The time varies with product, conditions and joint depth, and we confirm it for each area before we leave. Keeping the area coned off until then avoids tyre marks and damage.

Joints sealed at the same time generally fail around the same time. It pays to check every joint, not just the obvious one so you can prioritise and budget. We’ll tell you which movement joints need doing now and which can wait.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Do you need expansion joint sealing in Marshborough?

The edges of the material can fail rather than the sealant. If the edge of the joint is friable, the bond fails with it so edge repair has to come before resealing.

Clients normally get in touch after noticing one or more of the following:

  • Arrises breaking up along floor joints
  • Brittle, chalky sealant on external joints
  • Joints packed with grit and debris
  • Torn sealant in brick or block movement joints

Schools such as Sandwich Technology School have movement joints in their walls and floors that are easy to overlook.

Our contractor checklist

On site: what to expect

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Smaller jobs around Marshborough can be grouped with others nearby. You will have a fixed quote before work starts.

  1. We assess the joints on site or from photos, noting widths and how each has failed.
  2. A fixed quote names the sealant we propose and its movement class.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. The failed seal is cut out and both joint faces cleaned back to sound material.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Before we start on site

  • Tell staff and tenants when we will be in
  • Confirm the product named in the specification
  • Share your working hours and any access restrictions

Advice

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Broken or spalled joint edges, which need repairing before any sealant goes in
  • Leaks coming from the membrane rather than the joint seal
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

Not sure which it is? You can give us a call on 01277 525 020 or email us and we’ll tell you honestly.

The South East has large numbers of industrial estates and warehouses along the motorway corridors.

On a site such as Birnham Farm Business Centre, 0.8 miles south-west of Marshborough, the movement joints are in car park slabs, paving and building elevations.

Why it’s worth doing now in Marshborough

A failed joint seal doesn’t mean the slab, panel or wall needs replacing. Where the edges are sound, cutting out and resealing is enough. We will flag where edges need repair before sealing. Halls, stores and units around places like Marshborough may not be checked every day, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.
