Expansion joint sealing in Queen's Park, done properly

Few joints take as much punishment as those in a car park. Tyres load the edges, and de-icing salts and water work into any gap; 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. Most enquiries involve previous reseals laid over old sealant and movement joints with split or torn sealant, on cladding panel joints, car park decks and ramps and blockwork control joints. A specialist sealant contractor works differently from a general builder: in Queen's Park, that means joint design, primers and backing rod as standard.

Around Queen's Park, as across London, joints are under constant load, from basement car parks and loading bays to podium decks and busy mall floors. A failed joint lets water and debris in, and the edges soon spall, so it pays to act early.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

After the work

For the best life from the joints:

  • Clear dirt from joint lines during routine cleaning
  • Raise snow-clearing blades over deck joints where possible
  • Check joints after long freezing spells
  • Keep product details with the building records for the next reseal

Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.

Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall and the reseal becomes an edge repair as well. Keeping the seal sound avoids all of that.

When to call us in Queen's Park

The edges of the material can fail rather than the sealant. Weak or crumbling concrete, brick or render edges give the sealant nothing sound to grip.

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

  • Joints packed with grit and debris
  • Damp inside where a wall movement joint has failed
  • Car park joints leaking onto vehicles below
  • Brittle, chalky sealant on external joints

Phasing is what makes joint work possible on busy sites such as Mitre Bridge Industrial Estate (1.4 miles south-west of Queen's Park): one bay, aisle or car park row at a time.

What your quote should include

  • Can the work be phased to keep areas open?
  • What the guarantee covers, and for how long
  • Are they CHAS accredited or on Constructionline?
  • Will RAMS and insurance details be available?

Questions to ask before you appoint anyone

Diagnose, treat, sign off

We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. Planning a London job such as one in Queen's Park starts with access. Send the building rules and access times with your enquiry.

  1. We start with photographs, approximate lengths and any drawings, visiting where needed.
  2. We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
  3. Old sealant and debris are cut out of every joint.
  4. Edges are checked, and we tell you if any need repairing before sealing.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

What we need from you

  • Warn occupants and staff about the work
  • Send your site hours and access windows
  • Make sure the joints can be reached

Common questions from Queen's Park clients

Do you take on jobs in Queen's Park where loading and access are tightly controlled?

Yes. Inductions, permits and timed loading are routine for us in London. Send the building rules and access times with your enquiry. We allow for the ULEZ, which covers every borough

Would you work within a site like St Charles' Hospital?

Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.

Are you insured?

Yes. Mastic Doctor is fully insured, public liability included.

What exactly is a movement joint?

Put simply, it’s a planned break in a wall, slab or deck so the materials can move. Expansion joint is a name often used for the same thing.

When can you be on site?

Mention the site’s hours and access windows in your enquiry, and we will plan around them. You can reach the office between 8am and 5pm, Monday to Friday.

Do you reseal car park expansion joints?

Yes. Let us know the opening hours and which levels or bays have to stay available and we will plan around them.

What if the joint edges are damaged?

Spalled edges need repairing before a new seal will last and we’ll flag every length affected. A bead on a broken edge soon lets go.

Surface by surface

Car park decks and ramps

Deck and ramp joints take tyre loads, grit and de-icing salts. We use a sealant made for wheel loads and the expected movement with bays done in phases so the car park keeps running.

Cladding panel joints

Cladding panels move more than masonry as they heat and cool. A sealant with the right movement class is chosen in a colour confirmed for that product.

Slabs, ramps and loading bays in Queen's Park

The 3 miles around Queen's Park take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest. In London, decks, bays and service yards normally have to keep running, so joints are sealed in sections with each area handed back once cured.

University campuses such as Imperial College London, 1.6 miles south-west of Queen's Park, have car parks, paved walkways and building elevations with movement joints. Retail centres such as O2 Centre (to the north-east of Queen's Park) have floors, service yards and car parks with joints under constant traffic.
