From Pile Integrity and Static Load Tests to Crosshole Sonic Logging and NDT, we provide end-to-end foundation testing that eliminates guesswork.
At QA & QC Limited, we deliver comprehensive geotechnical and foundation testing solutions that help clients verify design assumptions, reduce construction risks, and ensure structural integrity.
Our testing services are carried out by certified engineers using state-of-the-art equipment and internationally accepted standards such as ASTM, BS, EN, and ISO codes.
We provide practical, accurate, and cost-effective testing solutions that serve engineers, contractors, and developers in all sectors — from infrastructure and real estate to marine and energy projects.
Pile Integrity Testing (PIT) is a low-strain dynamic test used to assess the integrity, continuity, and length of concrete piles. It helps identify potential defects such as cracks, voids, necking, bulging, or soil inclusions within the pile shaft.
This test is quick, non-destructive, and ideal for quality assurance during or after pile installation.
Benefits:
Static Load Testing is the most reliable method for determining the ultimate bearing capacity of a pile or foundation. The test involves applying incremental loads (in compression, tension, or lateral directions) while monitoring pile settlement or movement.
SLT provides direct confirmation of pile design performance and is often required for critical structures like bridges, high-rises, and industrial foundations.
Benefits:
Dynamic Load Testing uses high-strain impact energy to assess pile capacity and structural integrity in real time. This test measures force and velocity during pile driving or restriking, allowing engineers to evaluate pile behavior quickly and accurately.
DLT is cost-effective and correlates well with static load testing results, making it ideal for projects with large pile quantities or limited timelines.
Benefits:
Crosshole Sonic Logging (CSL) is a non-destructive ultrasonic test used to evaluate the homogeneity of concrete in bored piles or drilled shafts. By transmitting ultrasonic pulses between multiple access tubes, CSL identifies flaws such as voids, honeycombing, or segregation within the pile body.
This test is crucial for quality control in critical infrastructure and high-load-bearing foundations.
Benefits:
Non-Destructive Testing (NDT) includes a range of techniques used to assess the condition and strength of concrete and structural materials without impairing their usability. These methods include:
Ultrasonic Pulse Velocity (UPV) Test – Measures concrete quality and uniformity.
Rebound Hammer Test – Estimates surface compressive strength.
Half-Cell Potential Test – Evaluates corrosion activity in reinforcement.
Benefits:
Our site investigation services provide critical data about subsurface conditions to aid in safe and efficient foundation design. Using advanced geotechnical techniques, we collect soil samples, conduct field and laboratory tests, and provide professional analysis and recommendations.
