Terratest - Precast Piles
The piles are driven with modern, free-fall equipment, using a hammer of between 5 and 9 tons raised either by a simple cable system, or the most advanced high performance hydraulic drive methods. This equipment is completely autonomous (requiring no auxiliary components) and mounted on crawler-cranes for easy ...

Terratest - Bored Piles
Extraction piles, bore-cast and concreted «in situ», constitute one of the classic foundation systems for problems arising from the soil´s bearing capacity or from the need to carry the heavy loads transmitted by the structure. The pile diameters that can be achieved have no limitation, but generally vary progressively between 400 and 2500 mm. The depths that can be reached exceed 60 ...

Terratest - Model CFA - Continuous Auger Bored Piles
The continuous auger bored piles belong to the category of bored piles with partial soil removal. Drilling is performed by means of a hollow, continuous auger. This technique allows the production of piles with diameters varying from 300 to 1000 mm, for a maximum depth of 30 ...

Terratest - Micropiles
Micropiles are small diameter cylindrical holes (between 114 and 400mm), into which a tubular metal frame is introduced, normally with a high elasticity limit (also bar reinforcement is used). It is joined to the ground by the means of a pressure injection of cement grout or ...

Terratest - Diaphragm Walls-Trench Cutter
Continuous reinforced concrete core walls are vertical walls made in spans of up to 7 metres in length and thicknesses between 0.40 and 1.50 metres, and depths of up to 70 m, and offer a solution to excavation difficulties in urban areas or around the water table ...

Terratest - Soil Nailing
Soil nailing is a technique used to bring soil stability in areas where landslides might be a problem. Soil Nailing can prevent landslides by inserting steel reinforcement bars into the soil and anchoring them to the soil strata. It is called Soil Nailing, because it’s like having a nail being hammered into the soil, where the nails, are the steel ...

Terratest - Ground Anchors
Ground anchors (both temporary and permanent) are a technically and economically competitive solution, because they facilitate the process of bracing and reduce the execution time of the works, providing a high level of security thanks to the technical development experienced in recent decades. Ground anchors are principally designed to absorb tensile forces. To perform this task, the anchors are divided into four ...

Terratest - Stone Columns
As a general rule, stone columns are executed with a vibrator with lower discharge and a discharge chamber and an extension feed tube on the top. Thanks to the feed tube and the compressed air, the gravel is pushed to the end. For this special equipment, Terratest has created a guide frame that enables driving and lifts the vibrator, the gravel then falling into the outlet hole. The vibrator then drops back down into the gravel, compacts it and expands ...

Geopier - Model GP3 - Soil Reinforcement System
GEOPIER soil reinforcement and improvement solutions are intermediate foundation techniques that are alternatives to the traditional solutions of excavation and soil replacement, structural fillings, foundation shafts and preloads, which take a long time to achieve their effectiveness. They are the result of continuous development and research to provide foundation and settlement control solutions on soft and compressible cohesive ...

Terratest - Metallic Bracing
The scope of use of the TERRATEST metal bracing system includes any type of work (building and public works) in which a diaphragm wall, of any type (continuous, pile or micropile) is to be constructed, and in which metal bracing is feasible geometrically. TERRATEST is able to offer its customers a metal bracing system designed to measure, and meet their needs from a technical and economic standpoint, and in addition, provide technical advisory services at ...
