Overlot Grading and Overexcavation
Due to swelling soils across the Denver area, residential development can become very costly as developers are required to provide a suitable foundation for single family homes. The recommended way to construct single family houses often boils down to two options; overexcavation of existing soil to place slab-on-grade foundation or drilled piers to bedrock. Overexcavation is conducted by removing the existing soil underneath the home and moisture conditioning it to a pre-determined level provided by the soils engineer. Adding water, stabilizes the material in the hopes to help mitigate swelling of the soil in the future. Once swell is mitigated, developers are able to construct houses with slab-on-grad construction.
The alternative would be to drill piers to bedrock for each home in order to support the foundation. For most projects the most cost effective construction is to mitigate the swell by overexcavation of the onsite soils with large earthmoving equipment so that slab-on-grade construction can be utilized. Bemas conducts overexcavation by excavating often ten to twelve feet below the bottom of basements for a section of homes. The area is then backfilled with onsite material which is moisture conditioned and compacted. The home sites are then backfilled up to design elevations as established by the developer. Bemas continues the same process for all home sites throughout the subdivision. After completion, each lot is drilled by a geotechnical engineering firm to verify that the site was built per their recommendations.
