We successfully completed a sump pump system installation project in Bothell. We removed existing vapor barriers and standing water, dug deep trenches, laid lava rock, installed perforated pipes, and placed plastic backfill basin. Additionally, we covered trenches with drain rock, installed iron cast sump pump system, and channeled pump water away from the house. Rodent-proofing was also conducted. In addition, we installed new 10 mil white vapor.
