Our Services include:

Field Testing

• rebar surveys (scanning for embedded rebar with the profometer) on concrete and masonry structures
• core removal and testing of concrete and masonry
• URM tests: in-place shear tests on brick masonry mortar, tensile and torque tests on anchor bolts
• investigations into existing structures to determine the construction materials and properties,connections, dimensions, etc.
• proof load tests (tensile and shear) on embedded anchor bolts and dowels
• static load tests on skylights and roof access panels per OSHPD and ORS requirements
• tensile pull-out tests on earth anchors
• moisture emission tests on concrete
• water leakage tests on metal curtain walls, windows, skylights, joint sealants per AAMA specs
• coefficient of friction tests on floor surfaces
• "customized" tests specified by the design engineer

Laboratory Testing

• concrete, shotcrete, grout, mortar
• masonry: CMU block, brick, concrete and clay roof tiles
• steel reinforcing bars
• structural steel
• high strength bolts
• sprayed-on fireproofing
• ceramic tile
• hydrostatic pressure tests
• calibration of hydraulic ram loading systems
• welder and welding procedure qualification tests on plate, pipe, tube, sheet steel per AWS, ASME, and military standards
• ICBO and IAPMO evaluation tests for construction products
• In addition to the standard ASTM and UBC tests, we perform customized structural load tests on construction materials and mock-ups to provide data for engineering analyses

Consulting - Field investigations into material failures

• concrete - crazing, dusting, pop-outs, curling, low compressive strength
• portland cement plaster/stucco - cracks, spalling, cement content evaluation
• vinyl composition tile (VCT) installations - adhesive loss, splitting, blistering
• ceramic tile installations - debonding, cracks, surface spalling, mortar shrinkage
• terra cotta tile facades - moisture intrusion, glaze delamination
• floor underlayments and patching materials

Special Inspection - AWS, ICBO; ACI Certified

• structural steel / welding - shop and field inspection, welder qualification, procedure qualification, high strength bolting
• reinforced concrete - rebar and concrete placing, sampling, field tests
• prestressed concrete - tendon, rebar and concrete placing, sampling, field tests, stressing
• structural masonry - masonry unit, rebar and grout placement, sampling, field tests
• spray-applied fireproofing - application, sampling, field tests
