Preventive waterproofing
Basement car parks tend to be long, narrow, large-area structures extending over one or more underground levels. In the absence of suitable safeguards, large-size structural elements are much more prone to cracking and subsequent water infiltration than structures comprising smaller-scale elements. A further factor that exacerbates cracking problems is the frequent exposure of such structures to ambient temperature fluctuations. Waterproofing solutions for publicly accessible buildings also need to allow for the risk of wilful damage or vandalism.

Typical project features:

• Long, narrow structures
• Medium-sized to large concrete bays
• Commonly of monolithic construction

Potential risks:

• Complicated geometry of structural elements
• Temperature fluctuations
• Vandalism

Rascor provides:

• Integral "White Tank" waterproof concrete basement system
• Joint sealing
• Subdivision of bays using crack-inducing units
• Waterproofing of penetrations
• Reinforcement optimization

Remedial waterproofing
The generally monolithic construction tends to facilitate rapid leak location and repair. Given the temperature fluctuations acting on the structure, the problem may not be solved simply by grouting the existing leaks. Such cases may call for the incorporation of a grout curtain or membrane behind the structure. Here, RASCOR provides suitable products and solutions to cater for all waterproofing needs.
