A crest is the highest point that a river or source of flowing water will reach during flooding or heavy rain. Seattle Rockeries' geotechnical engineers help us determine these points so we can build drainage systems that keep your foundation and feet dry in the harshest rainfall. Failure to build above the crest of drainage trenches, troughs, and channels can result in flooding and property damage.

If your drainage systems are flooding and rising above their designed limits, call Seattle Rockeries today at (206) 960-9003 or email us at This email address is being protected from spambots. You need JavaScript enabled to view it. to get a quote!
