CPTu – Test Description (BR)
CPTu – Granulometric behaviour (BR)
CPTu – Dissipation Tests (BR)
Piezocone Tests (CPTu)
The Piezocone Penetration Test (CPTu) is recognized as one of the most effective tools for geotechnical and geoenvironmental site characterization worldwide.
Beyond its speed and operational efficiency, the CPTu provides continuous profiling and is highly adaptable to a wide range of soil conditions. Its advanced sensors allow for near-instantaneous stratigraphic interpretation, making it a reliable and versatile method for subsurface investigations in both routine and complex projects.
Flat Dilatometer Tests (DMT) – Test Description (BR)
Flat Dilatometer Tests (DMT)
Utilized in over 40 countries, the Marchetti Dilatometer Test (DMT) is a highly effective in-situ tool for geotechnical investigations, particularly well-suited for evaluating soil deformability parameters.
Renowned for its simplicity, robustness, and repeatability, the DMT offers consistent results and is supported by a vast body of published technical literature. Its ability to provide intermediate parameters—such as horizontal stress index, material index, and dilatometer modulus—makes it a valuable complement to other in-situ and laboratory tests in both design and quality control applications.
Ménard Pressuremeter Test – Test Description (BR)
Ménard Pressuremeter Test (PMT)
Widely used in France, the Ménard Pressuremeter Test (PMT) is a key tool for in-situ geotechnical investigations.
It provides direct measurements of soil deformability and strength, making it ideal for stress–strain analysis and foundation design.
Vane Tests (VST)
Vane tests are widely used to determine the undrained shear strength (Su) of cohesive soils under in-situ conditions, particularly in soft and sensitive clays.
We employ Type A equipment, which is designed to ensure higher accuracy and reliability in field conditions, making the test especially suitable for stability analyses, foundation design, and slope evaluation.
Standard Penetration Tests (SPT)
The Standard Penetration Test (SPT) is the most widely used and traditional in-situ geotechnical investigation method in Brazil.
It provides essential data on soil resistance and stratigraphy, supporting foundation design, compaction control, and general geotechnical characterization.
Rotary Drilling
Rotary drilling is a core method for investigating rock masses, allowing the recovery and classification of rock cores for geotechnical, geological, and hydrogeological analyses.
At Damasco Penna, we are equipped to perform various rotary drilling techniques—such as conventional, wireline, and PQ/HQ/NQ systems—reaching depths of over 800 meters, depending on project requirements and geological conditions.
Drilling and Sampling
Soil sampling methods vary according to the objective of the investigation, soil type, depth, and other site-specific conditions.
Over the years, we have developed solid technical expertise in obtaining both disturbed and undisturbed samples, using manual methods and hydraulic drilling systems.
Our sampling scope includes tools such as Shelby tubes, Denison samplers, split spoons (SPT), and augers, ensuring suitability for a wide range of analyses—geotechnical, physical, and chemical. Sampling procedures follow relevant international standards, such as ISO 22475-1 and ASTM D1587, to ensure the reliability and representativeness of collected specimens.
