Photos of a Typical Sub-Slab Depressurization System

Sub-Slab or Block Wall System: Hole is drilled in basement slab and suction is drawn from under the slab. Block wall systems are rarely used but can be effective in hard to mitigate homes.

Sump crock is sealed and suction is drawn from the drain loop.

The systems exhaust must terminate above the roofline

Internal System

Sometimes it is possible to route the system through a garage or even closets in the home to hide the piping.  The exhausts then exits the roof and looks like a normal stack pipe.

Operational Indicator

Shown here is a U-tube used to monitor system operation. The systems are so quiet it is otherwise difficult to monitor.
