Table 2 Grout Efficiency
From: Estimation of base grout quantity for cast in situ piles based on field test results
Soil Type Description | Permebility (m/s) | Grout Filling Condition for f = Filling Efficiency > 90% |
|---|---|---|
Silty Sand | > 10−7 | Fair Grouting |
Dense fine sand,silty sand | 10−7 to 10− 8 | Difficult Grouting |
Clayey Silt | < 10−8 | Very Difficult Grouting |
