Pipe & Well Abandonment in Portland, OR

What we fill in Portland

Common abandonment work around Portland (Portland Metro):

• Abandoned sewer and storm lines. Old sewer laterals, storm pipe and utility lines left in place under streets, yards and lots are commonly filled solid so they can't collapse or carry water.
• Utility conduit and culvert fills. Retired conduits and culverts get filled with grout, flowable fill or cellular concrete pumped in from one end.
• Underground tanks and vaults. Tanks and vaults taken out of service can be filled in place with pumped flowable fill or cellular concrete.
• Well fills. We pump grout or fill material for the well driller or contractor handling a well decommissioning.

Fill materials

• Cellular concrete. Lightweight foamed concrete that fills large voids, long pipe runs and annular spaces.
• Grout. A cement grout pumped through line fills pipes, cells and voids solid.
• Flowable fill / CLSM. Controlled low-strength material is a fluid, self-leveling fill that flows down long pipe runs and can be dug out later if needed.

We pump the grout or fill material. The well driller or contractor handling the decommissioning is responsible for permits and any state requirements.
