A drilling company with four decades in the field
Damasco Penna is a geotechnical engineering company founded in 1980, in Barueri (São Paulo, Brazil). It carries out subsurface investigation end to end: from percussion and rotary drilling to special field and laboratory tests, delivering to the project the ground profile, the strength of the layers and the water table that define foundations, retaining structures and earthworks.
What sets a drilling company apart is in-house execution. Damasco Penna works with its own crews and fleet, which secures schedule, quality control from field to report, and response on projects nationwide, including night shifts and high-compliance areas such as mining, industry and ports.
Borings we perform
SPT Drilling (Standard Penetration Test)
The reference test of Brazilian geotechnics, NBR 6484: N-value and a soil sample every metre. Available mechanized, with automatic hammer.
Mixed Drilling
Combines SPT in the soil and diamond rotary in the rock, in the same borehole, from top to founding level.
Mixed Drilling
SPT in the soil and rotary in the rock, in the same borehole, from natural ground to the bearing elevation.
Diamond Core Drilling
Deep, oriented boreholes for mineral exploration, with core sampling.
Beyond drilling, Damasco Penna performs field tests (CPTu, DMT, SDMT, vane and pressuremeter), laboratory tests, geotechnical instrumentation and environmental investigation.
Sectors and project types
Frequently asked questions about geotechnical drilling
What does a geotechnical drilling company do?
A geotechnical drilling company investigates the subsurface to give the project the ground parameters. It performs borings (SPT percussion, rotary in rock, mixed and diamond core), field tests (CPTu, DMT, vane, pressuremeter) and laboratory tests, delivering the soil profile, the strength of the layers and the water table that guide foundations, retaining structures and earthworks.
How to choose a drilling company?
Check whether the company performs the service with its own crews and fleet, whether it follows the standards (NBR 6484 for SPT, among others), whether it has a laboratory and certifications, and whether it covers your region. In-house fleet and compliance with standards are what secure schedule and reliable data for the project. Damasco Penna has operated since 1980 with its own crews and nationwide coverage in Brazil.
Does Damasco Penna operate throughout Brazil?
Yes. Based in Barueri (São Paulo) and with its own fleet, Damasco Penna mobilizes crews for projects across the entire country, including mining, industry, energy, ports and infrastructure fronts.
