Secure Shed

[Mortblanc]

I have owned several buildings with cellars and finished basements. Depending on the geography, water table and rainfall amounts, a big hole dug in the ground under a building, with no natural drainage, will require drains or pumps to remain dry.

My last house had a basement that was usable underground space but that was due to an extensive "French drain" system as well as a separate drain system against the concrete foundation and land sloping properly for good drainage.

The first house I owned that had a cellar also had a sump w/pump that kept it dry. I accidentally turned the pump off and a good soaking overnight rain resulted in the 25x35 cellar filling with water to the rafters. I had to turn off all power to the house and dive under water to reconnect the pump to power.

That is a lesson one only makes one time in life.
