In April 2014, Florida’s panhandle experienced a historic flooding event, which was highlighted by 20 in. of rainfall in just two days. For perspective, on average, the rainfall in this area is just more than 60 in. a year.

This once-a-century event caused numerous sinkholes, portions of Interstate-10 were closed and the soils of the entire region were completely saturated for an extended period of time.

One of the oldest and most cost effective methods of rehabilitating an existing drainage pipe is called sliplining.  With sliplining, a new, smaller “carrier pipe” is installed inside the old, larger “host pipe.” …
