Queen Street Bus Tunnel,
Brisbane, Australia,
waterproofed and protected
with Everdure Caltite.
The deep basement of the JP Morgan Bank HQ, Blackfriars, London, UK, waterproofed and damp proofed with the Everdure
Caltite System.
The prestigious IBM & Nestle Towers on Sydney's Darling Harbour. Underground plant rooms and eight parking levels, extending up to 19 metres below sea level, are waterproofed and corrosion proofed using Everdure Caltite System.
The second level of a sub-sea basement in Hong Kong adjacent to the sea is an air conditioned billiard hall. The
retaining walls with around 6 metres hydrostatic pressure are wall papered! |
Eliminate Messy Membranes & Tanking
and achieve massive time & cost savings
The EVERDURE CALTITE SYSTEM for waterproofing substructures such as basements, tunnels and retaining walls gives
many major benefits to owners, designers and contractors.
- Space-saving: Delivering maximum usable area to owner and user. No need for excavation to allow tanking application
or subsoil drainage layers, no need for cavity walls with drainage systems.
- Reduced construction time and cost: No need for time-consuming additional treatments - the concrete is waterproof
when placed.
- Reliable, time-proven damp-proof performance, including under hydrostatic pressure; On-going successful track record demonstrated over more than 45 years, in thousands of Caltite concrete structures, including roofs and podium decks, retaining walls, underground car parks, railway stations and commercial precincts, tunnels and virtually any water retaining applications.
- Simplified design and reduced design time: No need for laborious tanking detailing, installation and protection. Simply specify EVERDURE CALTITE SYSTEM HPI concrete on the drawings for any part of the structure in contact with water.
- Simplicity & Ease of Repair: Placement imperfections (e.g. "honey-comb" / faulty joint, etc) are quickly located and easily sealed from either side of the structure by filling with Caltite-modified non-shrink grout, or by PU injection. Moisture or dampness is not able to migrate around the repair area, or move into other parts of the section, because the capilllary pathways have been sealed by Caltite, and are not available to transport dampness/moisture or salts.
- Permanent in effect with advanced durability - CALTITE's unique Hydrophobic Matrix and Pore-blocking Action provides time-proven design-life durability and immunity to chlorides and sulphates.
Design Considerations
- Since effectively no water or moisture will transpire through properly compacted EVERDURE CALTITE concrete, only construction joints or projections / service penetrations through the structure need to be sealed. Cementaid provides simple, easy-to-use standard details for these areas.
- Applied renders or tile finishes, etc., should be bonded using a Cementaid WELDCRETE/cement bonding slurry, to ensure tenacious adhesion to the waterproof CALTITE concrete substrate.
