<br />t;ompletiol/ Report Of Grout Injection Remediation <br />The Pittman Residence - Zephyrhills, Florida <br />Claim No. 2800031710 <br />SDlI Project No. 3017839A <br /> <br />July 17, 2008 <br /> <br />. The contractor ordered 19 truckloads containing a total of approximately 180 cubic <br />yards of grout mix to the site. Of this quantity, approximately 171.9 cubic yards were <br />injected into the subsurface. <br /> <br />. The grout slump tests conducted at the site indicated a range in slump of 5.0 to 5.5 <br />inches. <br /> <br />Based on the above information, it is our opinion that the deep injection-grouting program has <br />been completed in substantial compliance with SDU's engineering recommendations and local <br />grouting practices. This grouting procedure was implemented to stabilize the subsurface <br />conditions related to sinkhole activity in the immediate vicinity of the foundation of the <br />structure. This procedure may not preclude development of new sinkhole activity in the future, <br />however. Table 1 in the Appendix summarizes the grout injection, including estimated grout <br />volume injected and initial depth of each point. Figure 2 illustrates the location and numbering of <br />the grout points. <br /> <br />It is SDU's understanding that cosmetic repairs will be done following the grouting operations. <br />Accordingly, any existing damage and/or collateral damage associated with the grouting <br />operations should be repaired at that time by a qualified restoration contractor. <br /> <br />CLOSING <br /> <br />SDU appreciates the opportunity to be of service to you on this project.
