Where Can This Shelter Be Installed?

Survive-A-Storm welded Extreme (EX) shelters are delivered as fully assembled units, making installation best suited for locations with clear delivery and placement access. Proper planning ensures the shelter can be positioned and anchored correctly for long-term performance.

Garage Installation

Garage installations are common when adequate access is available for delivery and placement. This location provides quick access during severe weather while keeping the shelter close to primary living areas.

Outdoor Installation

Outdoor installations are ideal for welded shelters, especially when direct delivery access is available. Shelters are typically installed on a reinforced concrete slab and may be placed under a covered structure for added protection from the elements.

Interior Installation

Interior installation of welded shelters is possible in select situations but depends on access for delivery. Because these units are fully assembled, doorways, hallways, and structural limitations must be evaluated in advance.

Commercial / Workshop Installation

Workshops, barns, and commercial buildings often provide sufficient space and access for welded shelter installation. Each project is evaluated based on access, slab conditions, and placement requirements.
