Testing

Thanks to our well-equipped concrete laboratory, we can provide comprehensive testing services for construction materials, such as Concrete, Grout, Cement, PFA, GGBS and Cement Stabilised Soil.

We can accompany you with:

• Concrete Test
• Grout Test
• Cement Test
• Pulverized Fuel Ash (PFA) Test
• Ground Granulated Blastfurnace Slag (GGBS) Test
• Cement Stabilised Soil Test (Deep Cement Mixing)

Testing of rocks mainly aims to simulate stress conditions that a rock sample is exposed to by nature, and to get the necessary parameters (such as stress, strain, elastic modulus, Poisson’s ratio properties) to evaluate specimen. We can carry out under ASTM standard.

Our package includes:

• Point Load Strength Index of Rock
• Porosity and Density Using Saturation and Caliper Techniques
• Porosity and Density Using Saturation and Buoyancy Techniques
• Direct Shear Strength of Jointed Rock
• Unconfined Compression Strength of Intact Rock Core Specimens
• Water Content of Rock

Testing the soil, also known as soil investigation or geotechnical investigation, is used to help determine soil properties on a construction site. We can provide all soil index tests and soil strength tests under GEOSPEC 3 or BS standard.

• Moisture Content Test
• Liquid Limit and Plastic Limit Test
• Particle Density Test
• Particle Size Distribution Test
• Density of Soil by Linear Measurement Method
• Dry Density/Moisture Content Relationship Test
• In-Situ Bulk Density and In-Situ Dry Density of Soils by The Sand Replacement Method
• In-Situ Bulk Density and In-Situ Dry Density of Soils by Nuclear Densometer Method
• California Bearing Ratio (Lab. CBR)
• One-Dimensional Consolidation Test
• Triaxial Compression Test
• Triaxial Test on Loosely Compaction Fill Material
• Direct Shear Test (Small Shear Box Apparatus)
• GCO Probe Test

We carry out quality control tests to ensure the integrity and performance of foundations.

FT Laboratories was the first company to provide PDA and CAPWAP testing in Hong Kong in 1979. Since then, our Foundation Department has been at the forefront of foundation testing in Hong Kong.

We offer a full range of tests for all types of foundations.

• Pile Driving Analysis and CAPWAP Analysis for Driven Piles
• Sonic Logging Test for Bored Piles
• Pile Integrity Test
• Ultrasonic Excavation And Drilling Profile Measurement (Koden Test) for Bored Piles
• Static Loading Test
• Strain Gauge and Skin Friction Analysis for Trail Piles
• Determination of Pile Length with Electromagnetic Method
• Determination of Pile Length with Parallel Seismic Method
• Pressuremeter Test for GI Drilled Holes
• Pull Out Test for Soil Nails
• Plate Load Test
• Time Domain Reflectometry Test for Soil Nails
• Verticality Check By Inclinometer for Drilled Holes
• Inclinometer Service
• Vibration Monitoring

Mechanical properties, such as strength and ductility of the materials are measured. Performance of the materials can be verified and the materials being used can be trusted.

• Fibre Reinforced Polymers (FRP) Reinforcement
• Mechanical Coupler
• Plastics/FRP Pipe Lining
• Steel Fabric
• Steel Fasteners (Bolts, Screws and Studs)
• Pull off Test (Bolts, Screws and Studs)
• Steel Reinforcement
• Steel Wire and Strand
• Structural Steel
• Welds
• General Mechanical Properties – Tensile Test
• General Mechanical Properties – Impact Test
• General Mechanical Properties – Hardness Test
• General Mechanical Properties – Flexural Test

Our team can carry out non-destructive testing. Test pieces are investigated non-destructively. Non-Destructive testing is considered as the best way to study components and structures that are in use or that will be in the future/about to be.

Our portfolio includes:

• Visual Examination
• Magnetic Particle Test
• Liquid Penetrant Test
• Ultrasonic Test
• Radiography Test
• Coating Thickness
• Electrical Capacitance Tomography
• Borescope Inspection

Our team can carry out a comprehensive chemical analysis of construction materials, that includes understanding their behaviour and chemical properties, to assess if they comply with industry standards. Depending on the specific requirements of our clients, FT Laboratories’ chemists can perfom detailed testing, including sulphate and chloride content together with pH level. FT Laboratories also has good experience in handling chemical composition analysis of Deep Cement Mixing (DCM) samples in vast scale for land reclamation work.

• Aggregates Test
• Cement Test
• Concrete Test
• Cement Stabilised Soil Test (Deep Cement Mixing)
• Soil Test
• Water and Wastewater Test
