PhosphoCreteTM
Madrid Engineering Group, Inc. (MEG) has developed a new and innovative method, called PhosphoCrete, to chemically stabilize soft soils on areas previously mined for phosphate. Pockets of soft, waste phosphatic (often called 'slimes') are highly compressible and weak and may be too extensive to excavate and replace. PhosphoCrete can permanently chemically alter the clay to create a stabilized platform on which to build.
The technology is based on research previously conducted for the Florida Institute of Phosphate Research (FIPR) in Bartow, Florida, involving some of the world's leading experts in clay stabilization. MEG has expanded the research, concentrating on developing mix designs and installation techniques that make the technology cost-effective compared to deep foundations such as pilings, excavating and replacing, or surcharge techniques. Recent efforts included an extensive laboratory test program, a field demonstration, and commercial applications.
