Fixing leaks in dams has always been a stressful venture. Not only are current methods expensive and slow to yield results. They often will resort to “trial and error” methods that may further strain the integrity of the structures rather than fix it.
Here at Guardian/Willowstick we offer our own solution. By using our patented state of the art geophysics and hydro-physics technology.
These sensitive instruments coupled with our field specialists, collect data all along project parameters. Using points collected in the data we create 3D models of the subsurface allowing us to gain insight on flow paths of the current leaks, potential issues arising if no remediation is done and finally predicting the effects that remediation may have going forward.
Willowstick utilizes technology that has proven effective in an array of fields including: geology, bio-magnetics, military, civil remediation and other scientific fields for the past 30 years.
Being the best in the world comes with a burden of pressure. For the past 12 years we have been continuously perfecting our technology to a industry leading 95% (MSR) success rate.
Willowstick investigations take days. Our competitors take weeks or even months. Using cutting edge data collection and model creation we form a seamless process from our field crews to our data analysts. We solve problems quickly, but more importantly, correctly.
Nearly all of our investigations can be performed using existing wells or piezometers (an instrument for measuring the pressure of a liquid or gas). This mitigates any need for expensive and time consuming drilling.
By energizing the water from one side of the reservoir to the downstream leak we can measure and map the induvial pathways the water takes. Once fully identified we can show this data in 2D and 3D allowing for clear steps forward in remediation.
Often our models are so clear that our customers will even use them for their “as-built” maps.
Having near real-time insight into the health of dams, reservoirs, canals (or other water features) allow us to tailor and modify our investigations as needed. Giving owners and operators to quickly make decisions based on our state of the art data collection rather than walking blindly towards possible solutions.
Another benefit of a Willowstick investigation is to observe and evaluate changes over time using our Willowstick Compare™ capability.
In much the same way that a dentist compares current x-rays with earlier ones, we create the possibility of our clients comparing the results of past Willowstick investigations with current results. This gives them the capability to gauge the effectiveness of remedial work, categorize the level of current concerns and determine the level of risk facing the dam, reservoir or canal.
Performing these investigations at regular intervals allow for a more comprehensive understanding of the health of the dam than what has been previously possible.
For 12 years and 130 different clients, our Willowstick investigations create clients that are eager for more. Over 75% of our business comes from repeat customers, because they know that our accuracy in modeling and predictions will always give them reliable results.
