Excavation, Earthworks & Backfilling
Precision rock and earth excavation, topographical site grading, and engineered layer-by-layer backfilling compacted to 95-98% Modified Proctor density with shoring systems.
95-98% Compaction Ratio
Strict layer compaction with Modified Proctor testing ensuring zero soil settlement.
Laser Topographical Survey
Exact boundary and level determination using Total Stations and advanced GPS.
Heavy Excavation Fleets
Heavy-duty excavators and hydraulic hammers tackling the toughest rock formations.
Engineered Shoring Safety
Engineered shoring systems securing site boundaries and protecting neighboring properties.
Earthwork Criteria & Certified Soil Compaction Standards
Site preparation and earthwork represent the bedrock of structural safety. RAACO engineers execute high-precision topographical surveys using GPS and Total Stations to delineate precise excavation boundaries and formation levels.
Excavations across varied geological rock and soil strata are powered by modern hydraulic excavators, rock breakers, and bulldozers, backed by engineered shoring systems that safeguard adjacent structures. Backfilling incorporates selective granular fill (A-1-a/A-1-b) placed in lifts not exceeding 30cm, moisture-conditioned, and compacted with heavy vibratory rollers to achieve minimum 95% Modified Proctor density (ASTM D1557) certified by independent testing labs.
