Preventive waterproofing
RASCOR's products and systems cater for all types of buried concrete structure, including bored tunnels. The immense variety of tunnelling and lining techniques used for such schemes is reflected by the wide range of associated waterproofing options. Waterproofing solutions play a pivotal role where tubbings are installed as the inner tunnel lining.

Typical project features:

• Construction dictated by use
• Long, narrow concrete bays
• Invert area inaccessible after completion

Potential risks:

• Complicated geometry of structural elements
• Temperature fluctuations
• Long construction periods
• Junctions with sheet membranes
• Cross-passages

Rascor provides:

• Joint sealing
• Detail solutions for junctions
• Subdivision of bays using crack-inducing units
• Waterproofing of penetrations

Remedial waterproofing
Depending on the specific construction, 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.
