Seven Hills — Balcony, Bathrooms & Laundry
Precision internal bathroom, ensuite, and laundry membrane installation alongside external balcony expansion joint sealing.
Flawless internal and external waterproofing for a premier Seven Hills home, featuring tiled balconies, shower hobs, wall niches, and laundry wet zones.
Balcony Expansion Joint Engineering
External balcony junctions were pre-treated with neutral-cure polyurethane sausage tooling, creating continuous elastomeric fillets. Puddle flanges were mechanically embedded and encapsulated to prevent water bypass between the screed and concrete substrate.
Full Room Encapsulation
Internal ensuites and main bathrooms were sealed seamlessly with Class III liquid polyurethane membranes, backed by our 10-year written waterproofing guarantee.
