A complete range of services

From the first borehole to the foundation drawing: solutions to recommend and deliver the right answer in foundations and earthworks.

Soil Mechanics

Bearing capacity, short- and long-term settlement, slope stability, stratigraphic profiles and shallow & deep foundation design.

01 / ROMELearn more

Geophysics

Resistivity, seismic refraction, seismic micro-zonation, crosshole, downhole and iso-resistivity profiles.

02 / ROMELearn more

Topographic Surveys

Planimetry, altimetry and resistivity with total station and geo-referenced drone flight via GPS, UTM coordinates and benchmarks.

03 / ROMELearn more

Soil Laboratory

Index and mechanical tests: unconfined compression, Mohr's circle, consistency limits and plasticity chart.

04 / ROMELearn more

Deep Boreholes

SPT drilling, diamond bit, Shelby and Denison undisturbed samples, open test pits and permeability tests.

05 / ROMELearn more

Pavement Design

Earth structure shaping, earthworks, embankments, dams, reservoirs and channels.

Deep borehole drilling

We reach where the soil tells the truth

Tripod rigs, portable PETY, Long-Year 34 rotary and Acker Hillbilly. Every rig runs the SPT test and undisturbed sampling.

SPT Test

Standard penetration with Shelby undisturbed sampling.

Diamond Bit

Rock coring in HQ, NQ and XL diameters.

Undisturbed Samples

Shelby tube in soft soils and Denison barrel in hard soils.

Open Test Pits

Direct excavation and sampling (PCA) for stratigraphic inspection.

Permeability

Lugeon and Lefranc tests, constant and variable head.

Marine Works

Boreholes for docks, breakwaters, marinas and intakes.

Projects

Real work, done in the field

Where we work

Foundation & earthwork solutions for every civil project

We recommend and deliver the right solution for each project, from the home to major infrastructure.

Foundation types

From stratum to structural support

We design the right foundation system for the bearing capacity and settlement of each ground.

Each wall or column bears directly on the surface stratum when it has good bearing capacity.

How we work

A clear method, from ground to drawing

1

Reconnaissance

Site visit, topographic survey with total station and drone, and borehole layout.

2

Exploration

SPT drilling, undisturbed sampling and field geophysical studies.

3

Laboratory

Index and mechanical tests under ASTM to characterize each stratum.

4

Analysis

Bearing capacity, settlement, stability and geotechnical model.

5

Delivery

Report and soil-mechanics drawing with the recommended foundation design.

Frequently asked questions

Everything about your soil mechanics study

The questions we hear most before starting a geotechnical study. Got another one? Message us on WhatsApp.

It is the geotechnical analysis of the subsoil —borings, sampling and lab testing under ASTM standards— that determines bearing capacity, settlement and the right foundation type for your project. It is the foundation for building safely and complying with the Building Code.
