Press Release Body = Water Intrusion Technologies has an advanced solution for
removing and keeping water out of subterranean concrete walls and slabs, which is
Electro-Osmotic Pulse (EOP) technology. Traditional methods for correcting water
intrusion involved the application of sealants or costly excavation around a
facility exterior. In 1994, a team of researchers and the U.S. Army Engineer
Research and Development Center (ERDC) began development of an innovative technology
for the prevention of water intrusion in below-grade concrete structures. This
technology has been successfully used in basements, elevator shafts, tunnels,
underground bunkers, crawl spaces and recently a roadway. The heart of this
technology is strategically placing an Anode (titanium strip) on the dry side and
Cathode (copper rods) on the wet side and passing a controlled current from the
Anode to the Cathode. Water attaches to the electrically charged ions as they move
from the Anode to the Cathode and therefore the water is removed from the controlled
media. One of the many challenges was keeping the rebar, which is embedded in the
concrete for strength, from corroding. A high tech controller, patent pending, was
designed to provide controlled current flow through the concrete and protecting the
rebar while managing multiple zones.

A multimillion dollar project using this technology was just completed in Santa
Barbara California. A Soggy Problem was the headlines in the Santa Barbara
News-Press on August 20, 2006. A highway off ramp and underpass has been the site of
many vehicle accidents costing California millions in lawsuits. A solution for the
soggy problem had stumped public works officials for decades. This underpass handles
over 20,000 vehicles a day. The paper went on to say, a fix would do more than dry
out the over 70,000 square feet of roadway. Success would allow Caltrans to put off
a $20 million to $30 million replacement of the interchange scheduled for 2012.
Caltrans did find a fix. They found out about Electro-Osmosis Pulse Water Removal.
This was a challenging project because of the square footage involved and the
concrete with reinforcement steel. OsmoTech did the installation over scene by the
U.S. Army Corp of Engineers. DSP Automation developed a new controller for this
application to power the anodes and protect the reinforcement steel. The system
covered the 70,000 square feet of roadway and consisted of 35,000 linear feet of
anode. Within five days of turning on the system, a once very wet roadway was dry.

We are currently involved in waterproofing underground bunkers. This has also been a
major problem for years. There are over 40,000 bunkers with moisture seeping through
the concrete walls and floors causing high humidity, mold and corrosion. This is a
very costly environment for equipment and humans. No other technology has
successfully kept the water out for any reasonable length of time.
