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

  • Permanent Sealing

    Permanent prevention of water ingress by sealing measures behind the structure

  • 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
