Most of Herriman sits on ancient Lake Bonneville lake bed deposits — which means heavy clay soil with high alkalinity, poor drainage, and a tendency to swell when wet and crack when dry. For homeowners and builders in Herriman, this creates specific challenges: retaining walls need proper footings and drainage to handle the soil movement, foundations require careful preparation and compaction, and utility trenches need to account for how clay behaves through Utah's seasonal cycles.
Add Herriman's hillside terrain, the dry washes that cut through parts of the city, and sloped lots backing up against the Oquirrh Mountains — and you have a community that genuinely needs excavation contractors who understand what they're working with. BullRok does.
Herriman's Lake Bonneville Clay Expands & Contracts — Here's Why It Matters
Herriman sits on Pleistocene-era Lake Bonneville deposits with expansive clay that swells with moisture and shrinks when dry. This soil movement is the #1 cause of retaining wall and foundation failure in the area. Every BullRok project in Herriman includes proper drainage design and compaction to prevent soil movement from undermining your investment.
