Permanent Sealing
Permanent prevention of water ingress by sealing measures behind the structure
Consolidation Line
WEBAC Consolidation Line product systems cover the entire range of injection systems for
Tunnel construction, dam building and mining
Sealing, stabilization and consolidation in tunnel construction, dam building and mining
Special Engineering
Sealing of foundation pits, leaking slot and sheet pile walls, stabilization of foundations and retaining walls, anchor bonding and filling of cavities and voids
The various requirements in this field are met by different product classes such as polyurethane, silicate resin and acrylate systems, each featuring specific properties. What makes WEBAC systems so special is their adaptability: the product systems can be adapted to the respective application in an ideal and individual way by adding small quantities of additives, accelerators, foaming agents or retarders.
Range of Application
Rock Mass Stabilization
Protection from unconsolidated rock or rubble sliding down and of fault zones; in general implemented between interior construction and rock mass
Filling of Voids and Cavities
Filling and stabilization of cavities, washed-out voids and gaps – mostly using expanding reaction resins
Consolidation Grouting
Consolidation of subsoil in dam construction and tunnelling
Tunnel Face Consolidation
Stabilization of heading faces in tunnel or gallery driving; mostly for preparing further stabilization measures
Umbrella Injection
Securing of tunnel driving operations against unconsolidated rock and rubble sliding down and when breaking through fault zones
Anchor Bonding
Installation of tie rods and injection nozzles for securing unconsolidated rock, fault zones and dams
Tunnel Face Pre-injection
Stabilization of loose rock, rubble or soil in tunnel driving for protecting the team and equipment when driving tunnels or galleries
