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
