Perform concrete coring, subgrade exposure, soil modulus testing, and slab replacement per engineering standards and site specifications. This included extracting concrete cores for compressive strength testing, exposing subgrade for soil evaluation, and reconstructing the slab with reinforced concrete and dowel connections.
Design Reference
All work followed site specs, engineering standards, and testing protocols.
Preparation
Mobilized crews and equipment; scanned for underground utilities before coring and slab removal.
Concrete Coring
Cored 9 holes across 3 locations for compressive strength testing.
Slab Removal
Saw cut and removed 4' × 4' slab sections at 3 locations to expose subgrade.
Soil Modulus Testing
Tested soil stiffness and load capacity at exposed subgrade points.
Slab Replacement
Reconstructed slabs with 30 MPa concrete, wire mesh reinforcement, trowel finish, and 10M dowels for load transfer.
Testing & Reporting
Delivered lab results for concrete strength and soil modulus.
Concrete cores and soil modulus data were successfully collected and analyzed. The slab was restored using reinforced concrete with proper doweling and finishing, ensuring structural integrity and compliance with engineering standards.
