Foundation defects cause approximately 30% of all documented dam failures in the United States.¹ Because of inherent uncertainty associated with the properties of the foundation it is essential that the regional geology and dam foundation geologic conditions be thoroughly investigated and characterized in order to reduce the risk of failure.

Dam Foundation Grouting, Revised and Expanded The Grouting Intensity Number (GIN) method was used for the first time in the foundation treatment of the Tannur Dam site, the first of its kind of foundation treatment in Jordan. 3m wide curtain was established under the dam body at both the left and right abutments, while a very extensive program of curtain grouting

Patil Institute of Technology, Pimpri, MH, India -----***-----Abstract –Grouting techniques in dams is one of the most emerging technique used now a days for repairing of dams. For strengthening of dams, various methods are used depending upon several challenges. Dam grouting improves
Remedial grouting of an existing dam is more complex than grouting the foundation before a dam is built, mainly because water seepage through the rock foundation may displace the injected grout. Additionally, the applied grouting pressure may cause hydraulic jacking or increase the uplift pressure, both of which can affect dam stability.

Grouting is one of the most popular methods used to control water leakage in dam constructions. The geological and engineering geological properties of the rock/soil to be grouted are important parameters influencing the design of the grouting.

Fredericksburg, Virginia . Specialty Grouting Subcontractor responsible for the installation of a 1,100 foot long single row grout curtain. The grout curtain forms a water seepage barrier in the rock foundation below a RCC Dam constructed concurrent with the foundation grouting.
In order to measure permeability of dam foundation area, lugeon test shall be conducted. Lu(lugeon value) is water volume injected at 10kgf/cm2 for 10 minutes per meter. The target Lu value after foundation treatment is generally 3 to 5. Grout system Stage Pressure (bar) Time duration of each step Pilot/Control hole Other hole 1st 1→3→1 9

They provide a 'safety valve' for the dam. Foundation problems can cause dams to collapse: This dam was partly overturned; other sections were washed downstream. Click on the picture for an enlargement and details. Typical layout of grout holes in a grout curtain. If the surface rock requires strengthening, blanket grouting could be appropriate.

Dam Construction Grouting Services Grouting can extend the life of existing structures that have experienced severe degradation due to scour or freeze/thaw damage. It rarely involves the need for heavy equipment, resulting in an economical method of restoration. In dam foundations three kinds of grouting programs are identified: Some cross sections of dams with rock foundations showing locations of drilled holes for foundation treatment. A- Curtain grout holes B- Blanket grout holes C- Special purpose, off-pattern grout holes D- Drain holes Rockfill dam with impermeable concrete face: Zoned earth UN BUEN PROFESIONAL .

Fine-grained foundations should be compacted with a roller. If the foundation is too firm for the tamping feet to penetrate, the foundation surface should be disked to a depth of 6 in and moistened before compaction. Smooth surfaces created by construction traffic on a previously Dam Foundation Grouting Foundation and geological structure: The foundation condition of the dam site is not suitable for each dam type. 3. Location and type of suitable material to be used in dam construction: There are three types of natural materials required for dam construction.
