Multiple Component & Crawl Space Systems Gallery
-
- A larger, high-volume multiple component system for a DC Public School. This building was originally built almost completely over a crawl space, in the 1920s.
-
- Split level slab configurations that require multiple suction points.
-
- Properly sealed sump cover with radon vent pipe for sub-slab depressurization. Note flexible coupling on vent pipe for easy disassembly for sump servicing.
-
- View of sealed sump component with “tee” fitting to sealed crawlspace component, and to radon fan mounted on exterior of building.
-
- View of “tee” fitting for multiple suction points in large, sealed crawlspace (sub-membrane depressurization system). Note properly sealed vent pipe at suction point through roof flashing in crawlspace membrane.
-
- High-volume radon fan for multiple component system, vented through large overhang and flashing on roof.
-
- Multiple suction points in large crawlspace system.
-
- Sub-slab suction point in multiple component & crawlspace system.
-
- Multiple suction points in large crawlspace and slab system.
-
- Crawlspace suction point properly sealed through roof flashing and connected to collection pipe under crawlspace membrane.
-
- High-volume fan equipped with noise reducer for large multiple component and crawlspace system.
-
- View of exterior of multiple component and crawlspace system showing exterior vent pipe and discharge point.
-
- Multiple suction points in large crawlspace and slab system. Note collection pipes connected to suction point and sealed under membrane.
-
- Multiple suction points in large crawlspace and slab system.
-
- Spit-level house system showing suction points in basement slab and slab on grade. Suction points for slab on grade in split level homes are usually drilled sideways under the slab through the foundation wall, from the basement.
-
- Multiple suction points in large crawlspace and slab system. Note collection pipes connected to suction point and sealed under membrane.
-
- Sub-slab and sub-membrane depressurization (for crawlspaces) systems integrated into one system.
-
- Crawlspace suction point in multiple component system.
-
- Sealed sump combined with sub-membrane system for sump and crawlspace situations.
-
- Multiple component system showing sealed sump with radon vent pipe for basement slab depressurization. Note pink flyswatter for perspective with next photo.

- Multiple component system showing sealed crawlspace with sub-membrane suction point integrated with sump system (previous photo). Slotted drain pipe is sealed under membrane and connected to vent pipe.
