Homeowners within the Lee's Crossing subdivision began to worry as they saw riprap channels begin to slough, and eroding banks begin enroaching into their yards. Heavy flash flooding made the problems worse.


Propex helped the City of Olive Branch work with the HOA to refurbish the neighborhood drainage system with reinforced vegetated channels using the PYRAMAT® 75 High Performance Turf Reinforcement Mat. The easy, rapid installation of the system was completed in less than a week.

The rapid installation of PYRAMAT® 75 HPTRM led to full protection of these drainage ways as a +100-year storm event struck one week after completion of construction.
