Elevated Slab System

In early 2005, PHS teamed up with Wright Engineers of Las Vegas to design a raised post-tension slab foundation system especially for use in high and highly-critical expansive and hydro collapsible soils, as well as areas with high water tables. Components of the Elevated Slab System include the Winslow Geo Anchor (a rotary installed steel anchor with single or multiple helix coils welded to an internal steel column that provides exceptionally high compression and tension capacity in unstable soil), and the Lateral Resistance Device (tested to over 20 kips, a “collar” that easily installs over the anchor, vibrates into position in seconds, and will consolidate surrounding soil and reduce all trenching) products together with a 5” one cable post tension slab monolithically poured over a void form allowing for expansive soil to rise and fall under the suspended post tension slab.

The Elevated Slab System is easily implemented by a local concrete provider, and reduces the need for soil preparation (import/export/re-compact) and accompanying spoils – thus reducing building cycle time. The System also mitigates future warranty and litigation issues, providing overall cost savings.
