Glossary of Excavation Terms:
Backfill: Soil or material used to refill an excavation once construction work is completed, helping to stabilize and restore the site.
Bedrock: Solid rock layer beneath loose soil or other surface materials, which may impact excavation depth or require special equipment to penetrate.
Bench: A step-like cut or level platform created in sloped terrain to prevent soil erosion and create stable working conditions.
Borehole: A narrow, deep hole drilled into the ground to examine soil conditions, locate underground utilities, or prepare for further excavation.
Compaction: The process of compressing soil or backfill to reduce air pockets and increase stability, typically done with heavy machinery.
Cut and Fill: A technique where soil or rock is excavated from one area (cut) and moved to another location to raise the ground level (fill), balancing earthwork.
Dewatering: Removing water from an excavation site, often through pumps or drainage systems, to keep the area dry and safe for construction.
Erosion Control: Techniques to prevent soil erosion during and after excavation, often involving silt fences, mulching, or other stabilization methods.
Excavator: Heavy machinery with a bucket or other attachment used to dig and move soil, rock, or other materials.
Footing: A structural foundation element placed below ground level to distribute building loads to stable soil layers or bedrock.
Grading: The process of leveling or sloping the ground surface to create a smooth, stable base, often done after excavation or before landscaping.
Haul Road: Temporary or permanent roadways constructed to transport excavated material to disposal sites or bring in construction supplies.
Overburden: Surface material, such as soil or rock, that lies above the area to be excavated and needs to be removed to reach target layers.
Perimeter Control: Barriers or containment measures used along excavation site boundaries to prevent soil runoff, dust, or water pollution from affecting nearby areas.
Shoring: Temporary support structures placed along excavation walls to prevent collapse and protect workers from cave-ins.
Silt Fence: A fabric or barrier installed to capture sediment in runoff, minimizing soil erosion and protecting nearby water sources.
Site Survey: A preliminary assessment of the excavation site, mapping out property lines, elevations, and existing utilities to plan safe and accurate digging.
Soil Classification: The categorization of soil types based on grain size, moisture, and other factors, influencing excavation techniques and equipment choice.
Subgrade: The soil layer beneath a road or foundation that's compacted to support the structure or pavement placed above.
Trenching: Narrow, deep excavation used to lay utilities, pipes, or foundations, typically requiring careful planning for stability and safety.
Utility Marking: Process of identifying and marking underground utilities (gas, water, electricity) to avoid damage during excavation.
Vegetative Buffer: An area of natural or planted vegetation along the edges of a site to absorb water, control sediment, and minimize environmental impact.
Vibration Monitoring: Assessing vibrations from equipment to prevent damage to nearby structures and minimize disturbance to residents.
These Terms should give a comprehensive overview for understanding and planning residential excavation projects safely and efficiently.
