Tunnel Oberau (D) – Compensation Grouting
Unexpected water ingress and poor ground conditions during underground construction usually escalate costs, can have a negative influence on the environment/construction process, and inevitably cause significant delays.
Grouting with cementitious products including additives, hydraulic binders, expanders or wash-out admixtures, also used as suspension, are hereby often carried out as a specific measure to counteract these risks. Additional, they are used as an economical approach to a wide range of different application fields, wherein Renesco offers its service:
Some specific assignment of these measures, for example to meet mechanical or hydrogeological characteristics, necessitates the knowledge of various ground parameters, like the stress-strain behaviour. The in-time-evaluation of these parameters in combination with surveillance and the ground reaction could be of essential.
Chemical injections or grouting are often use for the repair of structures, concrete elements or sealing components, where fast-reaction is necessary. The range can varies from a convenient one-component resin for small water sealing jobs to specialist robust multi-component systems to effectively stop massive water ingress problems.
Many of the products for preventing water ingress can be adjusted on site to give varying performance properties to suit the conditions using different accelerators, which requires a high demand on experience, material know-how and equipment technology from the specialised applicator. Additional requirements on health/safety and durability aspects have to be considered. Renesco offer its service in a wide range of application fields, like:
During the last five years Renesco has become a trusted international partner for the execution of specialised drilling works in combination with our grouting/injection technology…
State of the art grouting control and reporting systems ensure and secure the quality of the grouting process in order to meet specific grouting criteria and required projects specific standards. The grout control system provides data record, processing and a comprehensible steering of the process even in case of variable ground conditions. Real time monitoring incorporates a high work flow of data acquisition, processing and visualization to enable in time decision making and steering of the construction. Renesco offers these components including a wide range of experience and expert know-how.
