The strong currents of the famous rebel Guayabo River at it's highest point in the Anton Valley watershed almost destroyed a large area of privately owned land. Constant changes in the water levels has eroded the banks, causing ancient trees to fall helpless into the river's grasp. The construction of luxury residences "Los Portales" was suspended as the fight against nature seemed insurmountable. Traditional methods of erosion control had produced empty results as the river continued it's path of destruction. To solve the problem, Envirogrid EGA 306 layers, 6" tall and 5 cells deep, were stacked to build a 3 m high, 212 m long retaining wall. Click on the image to the left for the full case study.
