Settlement Control and Soil

Unacceptable levels of surficial settlement, resulting in structural distress, can occur when foundation soils are loosened by adjacent construction activity, as a result of soil consolidation induced by groundwater or leaking utility lines, from underlying sinkhole activity, or from insufficiently compacted bearing soils. When potential settlement is anticipated, such as that which could occur during soft ground tunneling in urban areas, compensation grouting can be performed concurrent with tunneling operations. For unexpected settlement, a range of grouting methods is available to cater to the site-specific conditions and project objectives.
