The multi-story parking station for the Sydney Adventist Hospital in Wahroonga, relieves a capacity bottle-neck. PENETRON technology was used to ensure a durable concrete structure and sealed, abrasion-resistant surfaces throughout the structure.The Sydney Adventist Hospital opened in 1903 as a Sanitarium to provide a place of healing. Since then, it has been affectionately known as the San. Now a world-class medical facility, the San offers comprehensive surgical, medical, and emergency services to more than 53,000 inpatients and 180,000 outpatients each year.
A key component of the San Hospital’s redevelopment project, the new multi-deck car park provides parking for almost 900 cars. The automated parking system also provides increased space for parking and enhanced on-site security for patients, visitors, doctors and staff.
“We’ve used the PENETRON System very successfully in a number of parking facilities,” notes Jozef Van Beeck, Director, PENETRON International Sales & Marketing. “It’s an optimal solution for both above- and below-ground designs, especially where there is any question of a high water table or exposure to the environment.”
“Our PENESEAL FH sealer penetrates deep into surfaces and reacts with the concrete ingredients to solidify them into a harder, denser, stronger concrete,” adds Mr. Van Beeck. “This gives the concrete a higher surface abrasion resistance and compressive strength, which can be particularly important during the construction phase.”
Concrete Supplier: Hanson

Areas Treated: Penetron Admix was used to treat all concrete used in the ground floor structure and the roof slab of the multi-floor parking garage to secure impermeability of the most exposed structural elements. Penebar SW45 waterstop was used to seal the resulting construction joints in the new concrete.
Peneseal FH, a clear, reactive penetrating sealer that permanently protects, preserves and strengthens concrete, was applied to all new concrete surfaces – a total area of over 20,000 m2 – for high durability.
