With summer temperatures regularly exceeding 95 degrees and average household size at 4.21 people, Pomona front steps endure heavy daily foot traffic and dry soil cycles.
Pomona rests on alluvial clay soils that swell in winter rain and contract during dry valley summers. In older neighborhoods where owner-occupied homes make up 52.6% of the city, original steps were often poured on topsoil without mechanical anchors. When drying earth pulls back from the perimeter, the unsupported concrete block rotates outward. That ongoing shift breaks porch handrails, cracks door trim, and opens a wide wedge between the landing and the front threshold.
To prevent this failure, technical guidelines from the Portland Cement Association specify mechanical anchoring and proper base preparation on active soils. We excavate four inches of native soil beneath the steps, place crushed rock, and drive steel dowels into the existing concrete stem wall. By tying the new steps directly into the house foundation, the entire entryway moves as one unified unit, eliminating rotational settling and keeping steps level.
