We know what's under your yard.
Wade Betlaf has spent 30 years working with groundwater in Western Washington, the last eight as Advance Drill Technologies, drilling for engineers who can't afford to guess. We now bring that same knowledge of the ground to homeowners who are dealing with water. Choose the side you need.
When you're standing in water.
Yard, crawlspace and foundation drainage across Western Washington. We start by finding out what your ground is doing.
- Standing water, wet crawlspaces, water against the foundation
- French, curtain and footing drains, tightlines, dry wells
- A written assessment before any digging
Subsurface data your design can stand on.
Geotechnical borings, monitoring wells and resource protection wells across Western Washington. Every hole is logged and sealed, and the well report is filed.
- Geotechnical borings drilled to your engineer's boring plan
- Monitoring and resource protection wells built to WAC 173-160
- Notices of intent, locates and well reports handled for you
Why one company does both
Both sides of this business answer the same question: what is actually under the surface, and what is the water doing down there?
For an engineer
That answer goes into a boring log and a foundation design. It needs to be accurate, documented and defensible.
For a homeowner
The same answer decides whether a drain will work or quietly fail after the first wet winter. The standard is the same.
What stays shared
The same licence, crew, equipment and habit of writing down what we find.
