CONDAT solutions for improving soil waterproofing during underground works. Use of neutralised sodium silicate grouts.
Description
The waterproofing grout can be used before the following work:
- underground car parks
- underground railway stations
- start-up shafts
- intermediate or exit shafts
- safety galleries between tunnels...
In such cases, waterproofing is achieved with soft gels such as CONDAT STAB SOFT. After injection, the treated ground can show permeabilities of less than 10-8 m/s. Soft gels bring cohesion to the soil, without significantly increasing the mechanical resistance.
