When the geologic and geotechnical investigations conclude that sinkhole activity or ground settling is occurring at the site, the Engineer could recommend that chemical grouting be utilized to stabilize the structure to minimize and further subsidence damage.
A high density chemical or polyurethane expandable grout is installed by Ureteck under low pressure to fill voids immediately beneath foundations and/or concrete slabs. This process will create a rapidly expanding polyurethane (or equivalent) foam that can lift, realign, and fill voids under concrete slabs and foundations being supported by base soils.
This process is used for industrial, commercial, and residential customers. Specializing in environmentally-friendly, patented Deep Injection Process to repair infrastructure damage, The URETEK Method controls foundation problems with minimal disruption to your home or business. The chemical grout depth, the estimated pounds of material and the amount of points will vary from site to site according to the engineer.
Continuous monitoring by C&N and the Engineering firms personnel during remediation is always done to verify compliance that these recommendations meet the necessary adjustments to the remediation programs. This will also allow the engineer who created the remedial design to certify that C&N’n remediation met the design specification after the professional stabilization is complete.
