Recently Completed Projects

Project located at the City of Sarasota, Florida

The Problem:

Water entering the wastewater system through holes, breaks and joint failures can significantly tax your treatment facilities, especially during storm events.

The pipe is buried 35 feet below grade, laid within a 10-foot barrier of tunneled bedrock, contained with 10 feet of gravel, and covered with 25 feet of compacted soil creating the foundation for the with the structure. During this time, phase 2 of the project continued unknowingly of the dilemma that was developing. Years of groundwater seepage throughout various locations towards the pipe was creating a questionable loose soil condition.

The Solution:

The company hired Foundation Professionals of Florida to inject two (2) component, fast reaction polyurethane foam to seal the leaks from the exterior. This method had the potential of foam intrusion to the sewer system rendering it completely useless. Bio-flow sewer camera company was hired to monitor intrusion sites to ensure further damaged was prevented and to provide a quality Pre and Post Video. After repeated attempts, the system failed to seal any leaks. This material has never been successfully delivered pasts the depths of 10-15 feet. Prior to total excavation, and as a LAST RESORT; Polymer Technologies U.S. was asked to utilize its patented technologies.


Property located at Altamonte Springs, Florida

This report documents the results of a Neutral Evaluation of the sinkhole damage claim for a residential property located at Altamonte Springs, Florida. The Neutral Evaluation program was conducted in accordance with Department of Financial Services. As required, the evaluation consisted of an inquiry of the parties and an independent investigation of the subject property as reasonably necessary to determine the existence, nature, and scope of a sinkhole loss and the nature, extent, and costs of necessary repairs and remediation.

The report shown below by Richter Enginering INC,  documents the chemical grout installation monitoring efforts. Six injection points were installed at 55′ below grade. A total of 2500 lbs of Prime Resin Precision Lift 4.0 was injected in a manner to not exceed 500 psig.


Property located at Tampa , Florida

 Universal Envineering Sciences was requested to perform a forensic geotechnical evaluation of a property located at Tampa, FL. Their analysis indicates that sinkhole activity was interpreted to be present within the subsurface borings conducted as part of the exploration…See geotechnical evaluation report shown below.

The report shown below by Richter Enginering INC,  documents the chemical grout installation monitoring efforts. Eight (8) injection points were installed around the perimeter of the structure.  A total of 3,560 Lbs of Precision Lift 4.0 was injected in a manner so that the gauge pressure of the lines did not exceed 500 psig.


Property located at Apopka, Florida 

The report shown below by Richter Enginering INC,  documents the chemical grout installation monitoring efforts. Six (6) injection points were installed between 35′ to 45′ below grade. A total of 4,200 Lbs of Precision Lift 4.0 was injected in a manner no that the pressure of the lines did not exceed 500psig.
