  • Blog | Dewatering for Tunnels and Shafts - Groundwater Eng

    Dewatering and groundwater control is often required as part of tunnelling projects – dealing with groundwater is one of the challenges of working underground. In the past tunnelling projects have occasionally suffered slow progress due to groundwater problems, or have even been flooded out due to inundation by groundwater.

  • Get Informed : The Basics - Groundwater Foundation

    Groundwater supplies are replenished, or recharged, by rain and snow melt that seeps down into the cracks and crevices beneath the land's surface. In some areas of the world, people face serious water shortages because groundwater is used faster than it is naturally replenished. In other areas groundwater is polluted by human activities.

    Artificial ground freezing for groundwater control and excavation support was developed more than a century ago. The technique is cost-effective in a relatively well-defined niche where both support of excavation and groundwater cut-off are required, and it is performed at significant depth or in difficult, disturbed, or sensitive ground.
