Remember that in the design of remedial measures there is continuing change, as new case
histories are published and the state-of-the-art advances. Examples include:
• The use of geotextiles (geofilters and geomembranes) in remedial work.
• Improved techniques to install concrete cutoff walls through embankments and
foundations.
• Improved grouting techniques and materials, such as the use of increased pressure,
computer controls, and micro-fine cement plus a wide variety of grout additives.
• Automated monitoring systems.
This unit describes emergency and temporary as well as permanent seepage control measures.
