Braced Excavation OptionsSLURRY WALLS SOLDIER PILES
Prevents horizontal flow of water
Can be used as permanent retaining wall
Excavation time doubled
Excavation cost increased by 30%
Time & Cost Benefits
Groundwater should not be an issue
Proper Spacing of planks can eliminate water pressure
SHEET PILES
Good to control seepage, construction below water table
Bracing needed – beyond property line
