Expansion joint sealing in Damerham

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Maintenance after handover

Once the work is signed off, these steps help:

  • Avoid parking heavy plant or pallets on joint lines
  • Keep stones and debris out of open joint lines
  • Inspect exposed joints once the cold weather has passed
  • Keep product details with the building records for the next reseal

On car parks, winter clearance can damage deck joint sealant. Lifting the blade at each joint avoids tearing the bead.

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. Catching it early keeps the water outside.

Expansion joint sealing in Damerham

If you need expansion joint sealing in Damerham, start with photographs and joint lengths. We will come and look where photos don’t show enough. You can also ring 01277 525 020 or send photos by email to talk the joints through. If you have weathered movement joint sealant that no longer flexes and water dripping through deck or ramp joints, we can help, on podiums and floor movement joints, brickwork movement joints and blockwork control joints alike. For commercial sealant work in Damerham, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

Halls, schools and small commercial buildings near places like Damerham have movement joints in brick, block and concrete too. They’re easily forgotten until water gets in or an edge breaks.

Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, call the office on 01277 525 020 or send details through our quote form and we’ll arrange a return visit.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. Then we strip out anything that has failed, prepare every joint and seal it. Jobs in and around smaller places like Damerham are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. We strip out the old seal and prepare the faces, and we tell you if any edges need repairing first.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. Where the maker calls for primer, it’s applied first, then the bead goes in and is tooled to a concave finish.
  6. Each joint is inspected and handed over with our 12-month guarantee.

Getting the site ready

  • Send asbestos survey details if the building is pre-2000
  • Have the specification and drawings to hand
  • Let us know about inductions and permits

Joints that move: notes for Damerham

At least three named trading, business or retail sites lie within about 3 miles of Damerham. Their warehouses, yards and car parks are exactly where joints take the most punishment. The South East is one of the drier parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open.

At places like Fordingbridge Business Park, 2.2 miles south-east of Damerham, joints are sealed a section at a time so operations carry on. For an occupier at a site such as Sandleheath Industrial Estate (1.5 miles south-east of Damerham), the joints at loading doors and dock levellers typically see the hardest wear.

Common problems we fix in Damerham

Some joints were never sealed with the right product. A stiff or general-purpose sealant across a joint with large movement won’t cope. Movement capability is set out in BS EN ISO 11600.

Common reasons buildings call us in:

  • Sealant pulling off the joint face
  • Leaks through car park deck joints onto the level below
  • Expansion joints filled with dirt and stones
  • Chipped joint edges on forklift routes

A healthcare site such as Fordingbridge Hospital, 2.8 miles east of Damerham, depends on car parks, ramps and service yards whose joints take traffic all day.

What to look for in a quote

  • Will RAMS and insurance details be available?
  • Can the work be phased to keep areas open?
  • Whether primer will be used where the manufacturer specifies it
  • Will CSCS-carded applicators be on site?

Our contractor checklist

When it isn’t the sealant

We check first that sealant really is the fix. It isn’t the answer for:

  • Waterproofing layers buried beneath the sealant
  • A joint that has to be widened or re-detailed before it can work
  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly before you book.

Where we work in Damerham

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

Surface by surface

Brickwork and blockwork joints

Mortar snots and debris in the joint stop it working. Everything is raked out before backing and sealant go in and flag any joint that seems undersized.

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability, and we will confirm the colours available for the specified product.

FAQs: Damerham

Can you work at a site such as Sandleheath Industrial Estate, by Damerham?

Yes. Estates, retail parks and business parks around Damerham, Sandleheath Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.

Would you work within a site like Fordingbridge Hospital?

Yes, healthcare and care buildings are part of our work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you cover Damerham?

Yes. We cover Damerham, and you can call 01277 525 020 or email us to get started.

How do I request a quote?

It works in four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.

Do the joint edges need to be sound before sealing?

Sound edges are essential. Where they’ve broken up, we’ll tell you they need repairing first, so the new seal has something to grip.

How much does the work cost?

That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.

What causes movement joint sealant to fail?

Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting.
