By 2020, 85% of all dams will be at least 50 years old, and significant changes in the downstream areas and watershed in general will have occurred. For these reasons, existing dams may present a variety of structural problems of which Gibson’s Pressure Grouting offers custom solutions to help solve:
- Slope stabilization may be required due to steep incline and/or erosion over the years. Techniques used in this case may include: soil nailing, anchor systems, and fractured rock grouting.
- Foundation repair may be required due to soft, eroding, or loose soils. Various grouting techniques are used to strengthen soils to prevent further foundation problems.
- Void grouting may be necessary due to leaking dam components. Cement grouting and Chemical Grouting are used as solutions to repair voided areas and control seepage.
- Additionally, in Dam Rehabilitation applications penstock and outlet structures are commonly relined in which case Gibson offers services to grout fill the annular space between the liner and existing structure. Every project might require a different grouting material, of which Gibson can provide the design and expertise.
