Post-tension Slab for Modular Building PDF Print E-mail

When considering a permanent modular structure, choosing a concrete slab floor has become a more common option.   In some locations, the soil conditions are very expansive.  This means the soil below the modular building will change (swell or shrink) over time.  This expansion causes traditional foundation systems to heave, crack or fail.  Historically, the only way to prevent foundation failure on expansive soil was to over-excavate the ground and “re-mix” it to include stabilizing additives.  This is a very expensive process.


 A ground supported post tension slab is a buffer that reduces differential deformations between the soil below and the steel prefabricated modular structure above.  The slab design will either resist or span over moisture-induced formations in the soil below, while maintaining its top surface within permissible level tolerances.
