Roads and highways. Road repair and replacement often requires stabilization of the ground beneath the pavement. One option: strip away the wet, soft or unstable soil and replace it with crushed rock. Or, just leave it there, and mix in cement. The soil will be stabilized within just a few days, saving both time and money. Additional benefits:
- Adding cement to the soil creates a strong and durable end result.
- Cement is produced under very strict standards, so is a very consistent binding reagent compared to other materials that are used for soil stabilization.
Contaminated soils. Many owners of blighted properties think their only option for treating contaminated soil is to dig and haul it. But, cements can also solidify soils containing a wide range of hazardous substances, pollutants, or contaminants, making treating in place a viable option. A very sustainable material, mixing cement into soil creates a physical bond that helps solidify the soil, stabilizing the contaminants and reducing leaching. Additional benefits:
- Treating in place is cost-effective: solidifying the soil, rather than disposing off-site, can yield more than 80 percent cost savings in some circumstances.
- Helps protect the environment: cleaning up contaminated sites and reinvesting in properties (such as EPA brownfield sites) uses existing infrastructure, and takes development pressures off of undeveloped land.
