How it Works

The wellpoint system consists of small-diameter wellpoints installed around the excavation, connected to a header pipe and vacuum-assisted pump. Groundwater is continuously removed, stabilizing the soil and preventing collapse.

Applications

• Basement and foundation excavations
• Pipeline and sewer line installation
• Underpasses and utility trenches
• Bridge and culvert works
• Road and highway projects in waterlogged soils

Step-by-Step Process

• Site inspection and hydrogeological study
• Designing layout of wellpoints around excavation
• Jetting or driving wellpoints into the ground
• Connecting wellpoints to header pipe and pump
• Continuous pumping and monitoring of drawdown
• Safe disposal of extracted groundwater

Key Benefits

• Cost-effective for shallow depths (up to 6m)
• Quick installation and dismantling
• Flexible for irregular excavation shapes
• Efficient in sandy or silty soils
• Safe, dry working environment for workers
