Hydrostatic Pressure

leave a comment »

We have a new theory about the water in our basement and I have Cyndie’s brother, Ben to thank for bringing it to my attention. Ben described a situation he experienced where a rug was acting like a sponge to pull moisture out of his basement floor. That could easily apply to the soaked rugs we encountered on our basement floor.

Coincidentally, hours before Ben called I had taken pictures of an interesting phenomenon occurring in the paddocks. Rain that we received around Christmas saturated our predominantly clay soil. I am always amazed in the winter when liquid water gets pushed up to the surface by natural hydrostatic pressure (the pressure exerted by a fluid… due to the force of gravity) and then freezes. It seems counterintuitive to me that there would be liquid water near the surface in the winter.

Well, with the uncharacteristically warm winter we have been having, there seems to be more liquid water than usual.

The darkened areas are “rivers” of ice that are forming where hydrostatic pressure is pushing water to the surface.

It would not surprise me if the water pressure in the ground around our foundation was pushing its way through the concrete in some way. We aren’t putting any rugs back down for the foreseeable future.

We happen to have a “lift system” to push basement wastewater up to the pipe that drains to our septic tank. After talking with the plumber on the phone, I looked into information on troubleshooting whether that pump was functioning properly. I admit that in the 11 years we have lived here, I’ve barely given that system a thought.

Apparently, it is recommended that an annual inspection be done to avoid major problems. Now we are considering having it checked for its first-in-a-decade inspection… whether it needs it, or not.
