Licensed Waterproofers Servicing Lane Cove & Surrounds

Searching for experienced waterproofers in Lane Cove? We specialise in waterproofing services in Lane Cove for homeowners, landlords, builders and strata managers. From balcony leaks to bathroom and basement repairs, our licensed team gets it right the first time – free inspection, written quote, 7-year warranty.

Properties across Lane Cove and the wider lower North Shore range from apartments and strata blocks to family homes on leafy streets. Each brings its own waterproofing challenges – older wet areas built before modern membranes were required, outdoor areas exposed to sun and storms, and below-ground walls that hold back wet soil.

Our process is simple: a free inspection, a clear written quote, proper surface preparation, the right membrane applied at full thickness, and testing and certification at the end. No shortcuts, and no paying twice for the same leak.

Balcony waterproofing membrane applied before new tiles Terraces

Balcony, Terrace & Courtyard Waterproofing

A balcony over a living room or garage needs a membrane that handles full sun, heavy rain and movement. We prepare the slab properly, correct falls where needed, and detail every edge, outlet and threshold so water drains away instead of finding its way inside.

  • Balconies, terraces and courtyards
  • External membranes to AS 4654
  • Door sill and drain detailing

Lane Cove Bathroom Waterproofing

Most bathroom leaks start at the same few weak points: cracked grout, a poorly sealed floor waste, or a membrane that stops short at the wall. We find exactly where water is escaping and fix it – with tile injection when the tiles are sound, or a new membrane when they’re not.

  • Leak repairs before you renovate or sell
  • Floor wastes, corners and junctions sealed
  • Certified membranes for renovations

Basement & Retaining Wall Waterproofing

Water pressure behind a wall never stops, so below-ground waterproofing has to be continuous – walls, slab and the joint between them. We seal construction joints and penetrations, then apply a membrane designed for constant moisture.

  • Dincel, block and retaining walls
  • Basement slab and joint repairs
  • Lift pit waterproofing

Swimming Pool Waterproofing Lane Cove

Re-tiling an older pool is the best time to waterproof it properly. We prepare and repair the shell, apply a pool-grade membrane and seal fittings and joints before your tiler starts.

  • Shell crack and joint repairs
  • Re-waterproofing before re-tiling
  • Fittings and penetrations sealed

  • Rooftop & Flat Roof Waterproofing

    Remedial roof membranes for homes, apartments and commercial buildings, built to handle UV, heat and heavy downpours.

  • Box Gutter Waterproofing

  • Lift Shaft Waterproofing

    Lift pits and shafts sealed against groundwater to protect lift equipment and stop corrosion in apartment and commercial buildings.

    A properly sealed laundry floor and upturn protects floors, walls and neighbouring rooms from washing machine and tub leaks.

  • Floor Waterproofing

    Concrete and screed floors waterproofed for wet areas, ground floors and commercial spaces where water must stay out of the slab.

  • Tile Injection Waterproofing

    Shower leaking but tiles still solid? Resin injected through the grout lines can seal it in a day, without a full renovation.

  • Planter Box Waterproofing

    Garden beds built against walls and over slabs are a common hidden leak. We waterproof and drain them properly.

  • Brick Wall Waterproofing

    External brick walls, parapets and chimneys treated against damp and salt so moisture stops reaching the inside of the building.

  • Water Leak Detection

    Our inspection finds the real source of a leak first, so you only pay to fix what's actually failing.

Know the Warning Signs

Signs Your Lane Cove Property Needs Waterproofing

Water damage gets more expensive the longer it runs. If you notice any of these, book a free inspection.

  • Stains on the ceiling below

    A bathroom, balcony or roof above is leaking through the slab.

  • White salt on brick or concrete

    Efflorescence means water is moving through the masonry.

  • Loose, drummy or cracked tiles

    The bond has failed because the bed underneath is wet.

  • Mould, musty smells or black grout

    Water is sitting behind tiles or inside the wall cavity.

  • Water in the basement or garage

    Groundwater is getting past below-ground walls or joints.

  • Wet patches below retaining walls

    Water is passing through the wall instead of draining behind it.
