Professional Waterproofing Services in Pyrmont, NSW 2009

Need dependable waterproofing in Pyrmont? Our licensed team provides expert Pyrmont waterproofing for houses, apartments, townhouses and commercial buildings. We repair leaking balconys, rooftops, basements and more using proven membrane systems, with every job backed by a written 7-year warranty.

Homes and buildings in Pyrmont – apartments and converted warehouses to offices – all rely on waterproofing that’s hidden under tiles, screeds and coatings. When it fails, the first sign is usually a stain, a musty smell or a loose tile, and by then water has often been escaping for months.

We waterproof internal wet areas to AS 3740 and external areas to AS 4654, prepare every surface properly before the membrane goes on, and finish with a compliance certificate where required. That’s how we can back our work with a written 7-year warranty.

Waterproofing Services Pyrmont

Waterproofing Services in Pyrmont

We offer the full range of waterproofing in Pyrmont, with particular focus on balcony, rooftop, basement and bathroom work – the areas where water causes the most damage when membranes fail.

Balcony waterproofing membrane applied before new tiles Outdoor areas

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

Pyrmont Rooftop Waterproofing

A roof membrane only works if every upstand, outlet and penetration is sealed. We prepare the surface, reinforce joints and corners, and apply a UV-stable system matched to how the roof is used – plant deck, terrace or non-trafficable roof.

  • Trafficable roof terraces
  • Upstands and penetrations detailed
  • Roof gardens and planters

Below-ground wall waterproofing before backfill Below ground

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

Pyrmont Bathroom Waterproofing

Showers leak when the membrane is cracked, missing at the hob or wall junction, or wasn’t sealed around the floor waste. In Pyrmont we test, trace and repair the actual failure point – then re-waterproof to AS 3740 so the repair lasts as long as the tiles.

  • Shower recesses, en-suites and full bathrooms
  • Membrane to AS 3740 with compliance certificate
  • Tile injection when tiles are sound
Bathroom waterproofing

More Waterproofing Services in Pyrmont

  • Box Gutter Waterproofing

    We line and seal box gutters, sumps and outlets so heavy storms drain away instead of overflowing into the building.

  • Lift Shaft Waterproofing

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

  • Laundry Waterproofing

    Laundries leak quietly behind machines and tubs. We waterproof the floor and walls properly so the problem doesn't come back.

  • 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

    Tile injection stops many shower leaks without ripping out the bathroom, so you avoid weeks of renovation.

  • Planter Box Waterproofing

    Planters and garden beds against walls or over slabs waterproofed and drained so roots and water stay where they belong.

  • Brick Wall Waterproofing

    Damp brickwork lets water track inside. We treat and seal masonry walls to keep moisture out for good.

  • Swimming Pool Waterproofing

    Membranes for concrete pools and spas, applied before tiling on new pools or as a remedial fix for a pool that's losing water.

  • 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

Warning Signs of Water Damage in Pyrmont

These are the early warning signs that waterproofing has failed. Catch them early and the repair is usually smaller.

  • 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.

  • Overflowing gutters in storms

    Box gutters or roof outlets can’t cope and spill inside.

  • 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.

  • Loose, drummy or cracked tiles

    The bond has failed because the bed underneath is wet.
