Subterranean Garage

Any type of underground construction presents challenges. Here at CAS we have intimate knowledge of soil behavior and water drainage, so that surrounding properties are not impacted.


The resulting structure is carefully encased, so that moisture seepage can occur.


We have experience in all underground construction including:

  • Ground excavation

  • Shoring up existing structure and excavated areas

  • Construction of concrete foundations and retaining walls

  • Structural steel fabrication

  • Installation of drainage systems

  • Waterproofing systems and moisture barriers

  • Interior finishes


Contact us now to find out how we can assist you in your unground building challenges!
