North Dallas Concrete is now building 10’ x 10’ x 8′ tall concrete storm shelters completely under ground. We excavate a 16’ x 20’ x 11′ deep hole in your back yard.
After pouring 10″ footings we set up wooden forms for all the walls and stairs. All walls are 8″ thick and 1/2 rebar 12″ on center is used.
We install a drainage system with a pump and use a water tight membrane to keep the room dry. The ceiling and floor is poured at the end and #4 steel for the ceiling is used 6″ on center.
We have 4″ ventilation pipes, an opening for a A/C and heating unit, and a sleeve designated for electrical power.
Options available: buildblock …styrofoam construction, interior finish out, generator back up system and an upgraded design to withstand explosions on top of load ratings.
