Expansion joint sealing for Hedgerley sites

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Maintenance after handover

Problems stay small when the joints are checked regularly. Specifically:

  • Brief car park operatives to protect joint lines during winter clearance
  • Record the sealant used and the date in the O&M file
  • Check joints after long freezing spells
  • Leave barriers in place until fresh joint sealant has cured

In warehouses, forklift and pallet-truck routes take the most wear. Keep racking feet and heavy point loads off joint lines.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint. Catching it early keeps the water outside.

How we handle expansion joint sealing in Hedgerley

A movement joint only works while its seal does. When the sealant splits or lets go, the gap fills with dirt and water, the joint can’t close properly and its edges begin to crumble. Resealing at the first signs of failure is far cheaper than repairing the material either side. If you have rain penetration at brick or block movement joints and joints packed with grit and debris, we can help, on blockwork control joints, cladding panel joints and car park decks and ramps alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Hedgerley it comes down to the same thing: the right product in a properly prepared joint.

Around smaller places such as Hedgerley, 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.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Hedgerley: questions and answers

Must our site in Hedgerley stop work while the joints are done?

Normally not: we work in sections and hand each one back once it has cured. We agree the sequence and timings with you before we start.

Is Hedgerley off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

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, because fresh silicone will not bond with aged silicone.

Who decides which product is used?

Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What guarantee do you give on joint sealing?

The workmanship is guaranteed for 12 months from sign-off, and we’re fully insured for public liability. Keeping joints clear of debris helps them last.

What’s the quickest route to a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.

Are your applicators CSCS-carded?

Yes. Our applicators hold CSCS cards, which many sites require.

Diagnose, treat, sign off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Hedgerley are usually 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. 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

  • Let us know about inductions and permits
  • For older buildings, check the asbestos register before work
  • Send any specification or drawings in advance

Advice

What we’re called out for in Hedgerley

Sealant peeling cleanly off one side is an adhesion failure. Dusty, damp or contaminated faces, a missing primer and three-sided adhesion are the usual causes.

Look out for the following:

  • Movement joints with split or torn sealant
  • Expansion joints filled with dirt and stones
  • New sealant over old, now failing
  • Spalled or broken joint edges in floors and decks

In a school such as Farnham Common Junior School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Before you book anyone

  • The named product and why it was chosen
  • The terms of the workmanship guarantee
  • Are they CHAS accredited or on Constructionline?
  • Their plan for phasing and protecting the area

Choosing a commercial sealant contractor

How the job changes 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, with a flexible sealant where movement is larger.

Podium joints

Podiums take foot traffic, planters and weather. We choose a product that copes with feet, wheels and weather.

When something else is needed

Honesty saves time and money. New sealant won’t cure:

  • Changing the joint layout or spacing of a structure
  • Movement on a scale no sealant is meant to absorb
  • Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)

If you are not sure, just phone 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

What we seal

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

Commercial clients in Hedgerley

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.

When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.

Slabs, ramps and loading bays in Hedgerley

Rainfall across the South East, Hedgerley 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 where de-icing salt is spread in winter, open joints let it in. At about 22 miles from central London, Hedgerley is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital.

Hospital campuses such as Spire Thames Valley Hospital (2.4 miles south-east of Hedgerley) grow in stages, leaving movement joints wherever new blocks meet old.
