Shelter Build Series 2

This shelter was installed discreetly in the side of a hill. The hole is excavated, gravel laid down and compacted, and the form board are built for the pad.

The floor pad has been poured and the tie-in rebar is in place. The first few courses of blocks will be laid over this rebar and concrete will fill all the block cavities. Note the perforated drain pipes laid around the perimeter and the river rock that allows water to run through it to the pipes.

The walls are completed, the blast door rough opening is made, and the ceiling trusses are being set in place.

The ceiling form boards are attached to the trusses and the steel ventilation pipes are installed on the bottom form boards.

The riser blast hatch is attached to the riser truss pair. Note the matrix of rebar that runs through and parallel to the steel trusses.

Ready for the ceiling pour. The concrete will also be forced down into the block cavities where it will tie in the floor, the walls, and the ceiling.

The ceiling pour completed. Note how secure the riser blast hatch and ventilation pipes are.

This shelter was finished with a corrugated roofing material and a plastic vapor barrier on the walls. Note the sealant around the vent pipes and other penetrations. Also note the slope of the roof toward the hill. Water is directed to the drain pipes between the shelter and the hill shown on picture number two, above.

The shelter has been backfilled. The installer painted the exposed blast door, shelter walls, and the retaining wall to match the ground color. A little bit of vegetation will complete this camouflage.
