đźš§Poor subgrade doesn't have to mean over-excavation and haul-off.
This parking lot had aggregate base contaminated with clay fines and sitting on high groundwater with a poor subgrade — a combination that keeps a section soft and unstable no matter how much you try to dry it out. Instead of digging it all out, we stabilized it in place with cement.
🔬 Cement hydration consumes free water and forms cementitious bonds between soil particles, reducing the plasticity index of the clay fraction — so the platform stays stable even with groundwater right below it. CBR typically moves from the 2-4 range up to 15-30+ within 24 hours, providing a stronger subgrade/base without hauling in fill or hauling out the poor soils. Cement content and moisture are controlled so the dosage hits target strength without over-cementing and cracking the section.
💪This is the work we do every day at Allstates Pavement Recycling & Stabilization (APRS) — CIR, FDR, SFDR, and soil stabilization across the country.
