Round Culvert

Strong & Durable Underground Shelters

The Versatility of Round Culverts

The most popular bomb shelter in the world is a round culvert pipe. While the modular square shelter is designed to be close to home as possible, the round culvert is designed to be as strong as possible. It not only allows the customer to bury it way beyond excavation capabilities but, it is using the natural strength of the earth as your main protection and not the thickness of the walls.

The round culvert is the least expensive way to make a strong durable underground shelter in a non-high water table situation. 10’ Culvert Pipe, if installed correctly, will hold up to 42’ of top soil. The corrugated walls make the interior silent, eliminating echoes that is mostly common in smooth wall shelters. The height of the ceiling in a 10’ diameter shelter is typically 7’ with 3’ of storage underneath the floors. The shelter parts bolt together, making this shelter extremely easy to install for Do-It-Yourselfers.
