Prison Gets Rehabilitated

An unstable floor at a Texas prison has settled over 7 inches and is in need of rehabilitation.  With relocating over 2,000 inmates out of the question, URETEK’s injection technology is a welcome site.

Even routine repairs present unique challenges within prison walls.

Fort Worth, Texas – The Federal Correction Institution located in Fort Worth Texas is unique among prisons in the United States in that the original purpose and use of the facility was non-prison related.  

The aging brick buildings located on the property were built in the 1930’s, once serving as a federal mental health institution and later on as a military hospital before being transferred over to the Federal Bureau of Prisons in 1971.

The converted buildings are now surrounded by 40 acres of high fence and barbed wire, housing over 1,700 male inmates and is located roughly 6 miles from downtown Fort Worth.

The Problem:

Recreation Hall Before Injection

Through decades of facility use, combined with weak soil and unpredictable climate conditions eventually caused structural and floor settlement in several of the buildings.  Some locations, such as the recreation hall, recorded over 7 inches of settlement over a 2,700 square foot area.

Throughout the years, several concrete repair methods were attempted to correct the continual floor settlement with none lasting the test of time.  This created a unique challenge for prison maintenance engineers to find a long lasting, concrete raising solution that was minimally disruptive and appropriately secure to ongoing, daily inmate regiments.

The Solution:

With minimal repair alternatives, prison officials turned to URETEK to raise and level the recreation hall.  URETEK’s non-invasive concrete raising technology consists of injecting light weight, ultra strong structural polymer though 5/8”, penny sized holes underneath the concrete floor.

This solution, known as The URETEK Method, is quick and powerful, providing precision lifting to realign sunken concrete of all types.  URETEK’s structural polymer cures and expands rapidly, reaching 90% strength in less than 30 minutes, giving operators surgical precision for leveling the concrete floor, critical for repairing older structural problems.

The Process:

Elevations Taken Prior to Polymer Injection

Before the injection procedure begins, existing floor elevations are recorded for future reference.  A string line grid is set to use as a visible reference during the lifting process.  A digital compu-level continually calculates elevation changes throughout the procedure.

The 3-man URETEK crew worked methodically throughout the settled recreation hall, raising the sunken floor with surgical precision, taking less than a day to complete the leveling process.

Once URETEK completed the project, pool tables and recreation equipment can immediately be placed back in the recreation hall ready for use.

As an industry pioneer, and inventor of structural polymer injection technology, URETEK also utilizes advanced, non-intrusive UAV site mapping to assist in detecting potential future structural and erosion issues before they become a larger and more costly problem to solve.

Summary

The Federal Bureau of Prisons has earned many accomplishments and faced extraordinary challenges since it’s inception in 1930.  With an agency goal of ensuring every inmates rehabilitation and return to community, URETEK is proud to provide a different kind of rehabilitation, returning aging prison facilities back into useful service.  For more information about the Federal Bureau of Prisons, click here.
