Waterproofing is one of those things that works invisibly when it is done properly and causes serious problems when it is not. For property owners in Newport, getting the right waterproofing work done the first time protects the building, reduces long-term waterproofing repair costs, and keeps occupants safe from the effects of water damage. Gemini Property Maintenance Group carries out waterproofing in Newport for residential and commercial properties across the full range of applications, from showers and bathrooms through to balconies, roofs, and external surfaces. We are a registered builder (DBU70140), certified waterproofers, and a family-owned construction business operating since 1984.

Where Waterproofing Is Required in Newport Properties

Waterproofing is not optional in the areas where water is regularly present or likely to penetrate the building fabric. Australian building regulations specify where waterproofing membranes are required and the standard they need to meet. Gemini applies waterproofing to that standard across all the areas that need it in Newport properties.

Common waterproofing services we carry out in Newport include:

·Shower recesses and wet areas

·Bathrooms and ensuites

·Balconies and external decks

·Laundries

·Roofs and roof terraces

·Retaining walls and below-ground structures

All completed waterproofing work comes with compliance and warranty certificates, which property owners need for building records and insurance purposes.

New Waterproofing vs Waterproofing Repairs in Newport

Waterproofing work in Newport falls into two categories. New waterproofing goes in during construction or renovation, before tiles or finishes are applied. Waterproofing repairs are carried out when an existing system has failed and water is already getting through.

Both require the same standard of workmanship, but repairs involve additional steps. Before a new membrane goes down, the failed system needs to be removed, the substrate needs to dry fully, and any damage to the building fabric needs to be addressed. Applying new waterproofing over a damp or damaged substrate shortens its service life significantly. Gemini does not skip those steps.

We also carry out full balcony and leak detection and repair work in Newport, which includes identifying the source of water ingress before any waterproofing work begins. Fixing the wrong area wastes time and money, and we do not recommend repair work until we are confident we have found the actual failure point.

How Waterproofing Fits Into Bathroom and Renovation Work in Newport

Waterproofing rarely sits in isolation. In a bathroom renovation in Newport, it is the critical step between demolition and tiling. In a balcony rebuild, it is the layer the whole finished surface depends on. Gemini manages waterproofing as part of our broader building and renovation capability, meaning it is always carried out in the right sequence and to the right standard within the wider project.

Our plumbing, electrical, and carpentry trades work alongside our waterproofing team on renovation and repair projects in Newport. The sequencing is managed internally, which means tiles do not go down before the membrane has cured and plumbing penetrations are sealed properly before waterproofing goes on.
