Underground shafts can benefit from the geotechnical construction techniques for the stabilization of walls, groundwater control, and filling in place for abandonment.
For the purpose of shaft wall stabilization, ground anchor systems can be installed as a vertical or lateral load-carrying element.
To allow for groundwater control, various grouting techniques, including cement grouting can be applied. This grouting essentially seals up all voids and fractures in the soil making the area much less susceptible to the slow leakage of groundwater into the shaft.
When an underground shaft is no longer in use, techniques including void fill grouting can be applied. Also called bulk grouting, this allows for the safe and effective decommissioning of underground structures. This method not only seals up the structure permanently, but it also keeps it from breaking down in the future, causing problems such as sink holes on the earth above it.
Gibson’s Pressure Grouting has the knowledge, tools, and resources to enhance or fix problems with any underground shafts in the southeast United States. Contact their geotechnical construction team with years of experience in the commercial, industrial, or municipal industries.
