Chemical Grouting

 Key Points

Chemical Grouting is another tool that can be utilized to treat unstable soil conditions. This approach can be used in conjunction with other stabilization techniques to fill out an effective treatment program that will deal with dual causes of settlement. In cases where there are naturally occuring loose sandy soils in the upper 5 – 10 feet beneath a sinkhole affected property, the deep compaction grouting will be utilized to remediate the deeper soils, and the chemical grout can lock in the loose shallow conditions that might go untreated with the deep grouting work alone.

Sinkhole Pressure Grouting

 Key Points   Insurance   Engineering   Grouting Specifications

Sinkhole Pressure Grouting involves the injection of a low slump grout, which is a mixture of cement, sand, water, and other additives into the soils at or above the limerock surface.

The purpose of the grout injection is to help seal off the limerock surface and prevent further downward migration of the supporting soil particles into the underlying cavernous bedrock zones. In addition to sealing off the porous limerock surface we intend to compact and densify the loosened supporting soils that have been affected by the sinkhole activity.

Structural Steel Underpinning

 Key Points   FAQ   Engineering

Steel Underpinning can help transfer the structural loads of a building down through a problem soil condition (i.e. Buried Debris, Organics or Shrink/Swell Clay) to a competent bearing strata below. In this application we are using a small diameter pipe pile that is hydraulically driven to refusal in 3.5′ sections, using the weight of the structure as a reactionary load to advance the pile.


Shallow Slurry Grouting

 Key Points   Engineering

Shallow Cement Slurry Grouting — can be used to help compact and densify a loosely compacted soil condition. This method can also be used to re-level slabs, and other lightly loaded structures. It can also be quite effective in filling washed out void spaces that may have developed under pool decks, or parking areas.



Helical Piles and Anchors

Key Points

Helical Piers are hydraulically twisted or turned into the soil much like a corkscrew. The piers contain one or more “flights” that pull the pier into the soil. These piers are screwed down until they reach soil that is dense enough to support the desired result. Since they are screwed in, they cannot be pushed or pulled out. They can be used to either support a structure or to keep a structure from coming away from the soil such as a retaining wall or a home on a hillside. These types of piers can also be used as pre-construction piers to prevent future foundation failure.
