About Us

Specialist Remedial Waterproofers

United Trade Links is a family-owned team focused on one thing: stopping leaks at the source when waterproofing has failed. We work with Sydney homeowners, strata committees, building managers and trades on balconies, terraces, rooftops and bathrooms.

We don’t do cosmetic refreshes or general tiling. We diagnose the failure, repair it with epoxy re-grouting and waterproof membrane injections, and back the work with a 10-year written warranty without lifting your tiles.

If your leak has been chased before and come back, that’s exactly the work we’re set up for.

Leaking Balcony

Fix Leaks Fast

Keep your tiles, save up to 98% on demolition!

Balcony & Terrace Leaks – NO TILE REMOVAL!

We use advanced epoxy re-grouting and waterproof injection systems to seal the source, block water ingress, and restore full protection.

Failed Grout = Failed Waterproofing

When grout cracks, shrinks or washes out, water gets straight through to the substrate underneath. We replace failed grout with high-performance epoxy that permanently seals joints and combine it with waterproof injection where the membrane has gone. The leak stops. The tiles stay.

Efflorescence Is a Symptom, Not the Problem

Those white salt stains aren’t a cosmetic issue — they’re moisture pushing through from a failed membrane behind your tiles. We treat the visible deposits, but more importantly, we fix the source: the failed waterproofing underneath. Surface cleaning alone guarantees the stains return.

My balcony has cracked or drummy tiles – can it be fixed?

Yes! If you have the same or matching tiles, we can repair them, so your balcony or terrace looks like new again — fully restored in both function and appearance.

The grout is damaged or failing – what can I do?

Our advanced epoxy re-grouting permanently seals joints against water, protecting your balcony from leaks.

No! Our waterproofing injection systems and high-performance membranes stop leaks while keeping your existing tiles intact.

How fast can the repairs be done?

We act fast and efficiently, minimizing disruption while delivering a durable, leak-free finish.

Will this save me money compared to full demolition?

Yes! You save up to 98% on demolition costs — no unnecessary tile removal.

What is efflorescence?

Efflorescence is a white, powdery salt residue that appears on tiles or grout when moisture pushes mineral deposits to the surface.

Is efflorescence a sign of a leak?

Yes — in many cases it indicates moisture movement behind tiles, failed waterproofing, or water ingress that needs attention.

Can efflorescence damage my tiles?

Over time, ongoing moisture can weaken grout, loosen tiles, and cause structural damage if not treated properly.

Can it simply be cleaned off?

Surface cleaning may remove stains temporarily, but without fixing the moisture source, it will return.

How do you fix it?

We remove the salt deposits, treat the affected area, repair grout if needed, and address the underlying moisture issue — without unnecessary tile removal.
