Common problems we fix in South Street

A slab keeps shrinking for a long time after it is cast, and the saw cuts are there so it cracks in straight, controlled lines. Each panel pulls back as it shrinks and the joints open up, and a filler placed early can part company with one face.

If one of these sounds familiar, it’s time for a closer look:

  • Soft sealant dragged out of trafficked joints
  • Failing joints at loading bays and dock doors
  • Open saw cuts full of debris
  • Grimy joint lines spoiling a showroom floor

A healthcare site such as Princess Royal Hospital, 4.3 miles to the north-west of South Street, depends on car parks, ramps and service yards whose joints take traffic all day.

Questions to ask before you book

  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • Who will actually carry out the work
  • Their pre-qualification and accreditations
  • How they’ll work around occupants

How to choose a sealant contractor

Floor joint sealing for commercial buildings in South Street

Few warehouses can shut a whole floor while joints are done, so we phase the work aisle by aisle or bay by bay. Share your site hours and access windows and the programme is built around them, with goods still moving in the areas we aren’t in. If you have cracked and crumbling joint fill and soft sealant dragged out of trafficked joints, we can put it right, whatever the surface. Most enquiries from South Street start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Around smaller places such as South Street, 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.

Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

How a job runs

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. Smaller jobs around South Street can be grouped with others nearby. A fixed quote is given before anything starts.

  1. Each area is assessed for joint width, arris damage and the wheels that cross it.
  2. A fixed quote follows, listing the treatment for each area and the order of work.
  3. Old filler, debris and contamination are cut or routed out back to clean concrete.
  4. Dust is extracted from the joint and primer applied where the manufacturer specifies it.
  5. Filler or sealant goes in to the right depth and is finished flush with the slab.
  6. Each phase reopens when the product is ready for wheels, then we start the next.

What we need from you

  • Agree which areas must stay open
  • Warn occupants and staff about the work
  • Have the specification and drawings to hand

Honest limits

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

  • Structural cracking in the slab
  • Damaged or worn floor coatings and screeds
  • Uneven floors that need grinding or levelling

If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think before you book.

What we seal

  • Construction joints
  • Forklift and pallet-truck routes
  • Loading bays
  • Retail and showroom floors
  • Joints along racking aisles
  • Saw-cut induced joints

Why it’s worth doing now in South Street

Waiting for a site-wide shutdown often means the joints keep getting worse. Phased in zones, the busiest routes can be treated first while the rest of the floor carries on. Converted and older buildings near places like South Street tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Why us?

  • Over 20 years of commercial sealing
  • Health and safety: CHAS accredited
  • Constructionline member for supplier checks
  • Fully insured, including public liability cover

Questions about South Street

Would you work within a site like Princess Royal Hospital?

Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.

Will you take on work at estates like Park Farm Business Park, close to South Street?

Yes. Estates, retail parks and business parks around South Street, Park Farm Business Park among them, are all within reach. A few photos and the unit address let us price the work.

How long does a job like this take?

That varies with the scale of the job, though a typical visit usually takes a day or more, depending on the metres of joint and how many zones the floor is split into. Larger or phased jobs take longer, and we will give you a timescale with the quote.

What happens if the joint edges are damaged?

A filler needs sound edges to grip. We will tell you if the joint edges need repairing first and set out how that affects the job.

How do we get a quote for floor joints?

Use our quote form, or email photographs and a plan, with the traffic on each area. A fixed quote follows that shows the products and zones.

Are your applicators CSCS-carded?

Yes. We use CSCS-carded applicators, as many construction sites ask for.

Will you just go over the old sealant?

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

After the work

For the best life from the joints:

  • Record damaged joints with a photo and a location
  • Ask drivers not to drag forks or pallets
  • Treat loading bay joints first if they’re failing
  • Tell us about strong cleaning chemicals before we quote

On younger slabs, a fine line can open down one side of a filled joint as the concrete keeps shrinking. It is a known trait of new floors and a later top-up deals with it in the majority of cases.

Joint damage starts slowly and then speeds up. Once the first piece is out, wheels drop further and hit harder so early treatment saves a lot of trouble.

What the job involves on each surface

Semi-rigid joint fillers

On industrial routes, a semi-rigid filler is often the right choice. They are installed to the depth the manufacturer specifies and finished flush.

Construction joints

Day joints on busy routes are prone to edge damage. We look at how much they are moving before choosing the treatment.
