At worst, familiarize yourself with the best water purification methods. If it is possible to construct a self-contained water system within the structure that is the best option. Your major priority in any survival situation will be water and survival equipment. The underground water discovery might be a nice potential source of drinking water later on, though. It’s usually best to just dig somewhere else. Underground water, on the other hand, is a problem that is difficult to deal with. Boulders can usually be removed by equipment or blasting. While digging you may encounter obstacles such as boulders and underground water. Wood really doesn’t have the strength to safely support the dirt above and at the sides anyway. Treated wood will last longer but will constantly leak poison. Wood is not generally a good choice due to decomposition. Steel is sometimes used instead of or in conjunction with concrete.


That way you have room to work around it during construction.Ĭoncrete is the strongest and most cost-effective material but others are possible as well. You’ll need to excavate the hole a bit bigger than the planned structure will be. Most people will want to hire or rent heavy equipment for the digging work, but digging by hand is certainly an option.
