Coordination with builders and trades
1. Waterproof
Substrates are inspected, detailed and primed where required. Membrane systems are applied to the specified thickness and coverage, including junctions, penetrations and movement joints.
2. Tile
Once waterproofing has cured and any testing is complete, tiles are installed with precise set-out, accurate alignment and consistent spacing. We ensure the correct adhesive selection and application methods are used, suited to the tile type and environment.
3. Finish
Final detailing includes clean finishes, accurate grouting and coordination with other trades to ensure fixtures and fittings align correctly. The result is a durable, compliant installation ready for long-term performance.
Residential Waterproofing
Bathrooms, kitchens, laundries, pools, outdoor areas and more.
We work with Sydney homeowners and renovation specialists to ensure wet areas are protected before tiling begins. Proper membrane installation prevents structural damage, mould growth and long-term issues.
Commercial Waterproofing
Compliant systems for commercial and institutional projects.
AMP Tiling & Waterproofing partners with Sydney builders and project managers to deliver waterproofing across commercial amenities, hospitality venues, multi-residential developments and institutional environments. We understand the importance of coordination, timelines and strict compliance requirements.
