Expansion joint sealing in Crampmoor, done properly

Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. Our applicators are CSCS-carded, we’re CHAS accredited and a Constructionline member, and we carry five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. We work on podiums and floor movement joints, cladding panel joints and precast concrete panel joints, and the usual reasons a site gets in touch are spalled or broken joint edges in floors and decks and new sealant over old, now failing. One point of contact handles commercial sealant work in Crampmoor from the first photographs to the final walk-round, for single jobs and planned programmes alike.

Halls, schools and small commercial buildings near places like Crampmoor have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Surface by surface

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler.

Brickwork and blockwork joints

Vertical movement joints in brick and block walls let the masonry grow and shrink. We use a sealant rated for the movement, typically low-modulus laid over backing rod at the correct depth.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is one of these:

  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Waterproofing layers buried beneath the sealant
  • Changing the joint layout or spacing of a structure

If you are not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer.

Surfaces we seal

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

What we’re called out for in Crampmoor

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, and specifications often refer to it.

These are often picked up first by site or facilities staff:

  • Debris jammed in movement joints
  • Car park joints leaking onto vehicles below
  • Weathered movement joint sealant that no longer flexes
  • New sealant over old, now failing

At places like Belbins Business Park, 1.4 miles west of Crampmoor, joints are sealed a section at a time so operations carry on.

Before you book anyone

  • Will CSCS-carded applicators be on site?
  • How they’ll work around occupants
  • Are they CHAS accredited or on Constructionline?
  • Will failed sealant be removed rather than covered?

How to choose a sealant contractor

When to bring in a specialist

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Diagnose, treat, sign off

When we get to site, we sign in, go through any site induction and check how permits are handled. Floors, finishes and fittings next to the joints are covered before any cutting starts, and the work usually 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. Jobs in and around smaller places like Crampmoor are normally planned as a single visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Where areas have to stay open, we agree a phased sequence before starting.
  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.

Before we start on site

  • Have the specification and drawings to hand
  • Share the asbestos register for older buildings
  • Let building users know which areas are affected

  • The asbestos register, for older buildings
  • The postcode of the building

Questions about Crampmoor

Is a hospital such as Romsey Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Crampmoor too small for you to travel to?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work while the building is occupied?

In most cases, yes. We phase the work so most of the building stays in use, with each area protected and signed.

Do you take on small jobs?

Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.

Do you need to see the site first?

It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

Do you take on multi-site work?

Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Expansion joint sealing around Crampmoor: how the place shapes the job

Rainfall across the South East, Crampmoor included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Crampmoor has at least three named business or industrial parks inside a 3-mile radius. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Business parks such as Sleepy Hollow Business Park, 0.8 miles to the north-east of Crampmoor, have car parks, paved areas and long brick and panel elevations, all with movement joints. Schools such as Cupernham Infant School have movement joints in their walls and floors that are easy to overlook.
