Pressure Grouting In Florida

A Deep Compaction Grouting Process For Florida Sinkhole Remediation And Foundation Repair


What Does Pressure Grouting Entail?

pdf-groutingWhen geotechnical engineers determine you have sinkhole conditions, The Sinkhole Pros at Foundation Services perform “Pressure Grouting,” also known a “Deep Compaction Grouting.”

We insert injection pipes with skilled precision down to the depth of the fractured, collapsed or eroded karstic bedrock, which in Florida is typically limestone. The depth of the pipes may vary considerably from one side of a structure to the other, as determined by detailed engineering specifications. A representative from the firm providing the engineering blueprint monitors injection point placement and other job requirements.

A concrete pump is then connected to the pipes, and our highly trained crews begin injecting a low slump grout to fill the voids and seal the karst layer (limestone). It is vital for this process to be completed with precision to prevent continued soil movement through remaining karst fractures and into the solution cavities. It is also vital to prevent and detect any movement in the structure. The jobsite Foreman watches sensitive surveyor-type equipment to monitor the structure for any movement as slight as 1/32 of an inch.

The Foreman also carefully monitors the pressure gauge we insert between the concrete pump and the injection pipes throughout the grout pumping process. When the pressure gauge reaches 300 psi, the karst area has been remediated and the grout pipe is extracted in 5 foot increments. Then the process starts over again through the next injection pipe until the karst area under each pipe is sealed, and the soils have been satisfactorily stabilized and compacted within 10 to 15 feet of the surface.

Our skilled teams use our own advanced, custom equipment and the best engineering techniques to minimize disruption to you and your property. All pipes are pulled with care to prevent any damage to your home and landscaping, and your property is restored from the sinkhole damage. We give you more than just a sense of security. We deliver!
