Pearson Composite Pilings

Pearson Composite Pilings are today’s preferred building material for waterfront foundations, docks, piers and bridges. Pearson composite pilings are stronger than wood, steel or concrete pilings, and because they will not rust, rot or crumble, they will last virtually forever. Containing no chemical preservatives that leach into the water, Pearson sustainable fiberglass composite pilings are environmentally friendly and are the choice of “green” developers of clean marinas and waterfront properties.

WIPP Flood Protection Training - AES Panama

January 2012

The WIPP water inflated dam is an excellent temporary and reusable flood control system. Daniel Senf trained personnel at this hydro-electric power plant so they are prepared the next time than flooding occurs due to high river water levels.

Zarumilla River Stabilization - Tumbes, Peru

October 2009

The Zarumilla River separates Ecuador and Peru. The Peruvian side had severe erosion and was stabilized with a flexible concrete slab which was produced by filling the Geoweb cellular confinement system with concrete. Engineering assistance was provided through Andex del Norte S.A. of Peru and general support by Daniel Senf.
