Concrete Slab Install or Mobile Base?

Concrete Slab Install

  • Anchored to an engineered concrete slab for permanent placement.
  • Best for schools, plants, campuses and community sites that need a long-term shelter.
  • Plan for slab design, site prep and local permitting in your schedule — we help you scope it.

Mobile Base (No Concrete)

  • Sits on its own steel base — no concrete to pour.
  • Relocates with your project: job sites, turnarounds, seasonal and temporary workforces.
  • Faster site prep and flexible rental terms.
