Orbis Terrarum is the exclusive distributor in Spain of two instruments for monitoring material compaction and for soil investigation and is also distributor of a pressuremeter. All this equipment is commonly used in the rest of Europe.
List of equipment:
Lightweight dynamic penetrometer PANDA2 Lightweight dynamic penetrometer with a continuous data recording and a specific software for interpretation and analysis.
This equipment was created in France in 1992, where it is widely used and has replaced the Gamma densitometer method for monitoring material compaction.
DThis method has its own French Standard XP P 94-105.
Its main applications are:
» Monitoring compaction of fills in earthworks, trenches: It can recognize multiple layers in a single measurement and analyze the compaction degree by specific reference Proctor test curves for each material.
» Investigation of soils up to 4 meters deep: Determination of resistance to penetration and bearing capacity of the tested terrain. Example of monitoring compaction test.

Light Drop-Weight Deflectometer ZFG3000 Light drop-weight deflectometer with total automatic measurement of dynamic modulus Evd (which has an equivalence with static modulus EV2).
It has been used in Germany for 35 years and has been spread worldwide with thousands of units sold, coming to replace the old plate bearing test because of its speed, lightness and reliability.
This method has its own German and Spanish Standard 103807-2:2008 UNE.
Its main applications and features are:
» Quality control: subgrades for roads and railway platforms.
» Easy handling, no additional load vehicle is neccessary, one man handling, multiple tests in a short time, immediate evaluation (indication of the dynamic forming module on the display, print out of one or more test records directly at the building site).

Ménard Pressuremeter
Controle Unit (C.U.), tubings and 3-cells probe to perform in situ Pressuremeter test in soils conform to the ISO 22476-4 and ASTM D-4719-00 Standards.
A Pressuremeter test is an in-situ stress controlled loading test performed on the wall of a borehole using a cylindrical probe which can expand radially.
From the test readings (volume variation based on controlled pressure), a stress-strain curve can be obtained, in the case of plane deformation, which yields: the Ménard Pressuremeter modulus, the creep pressure the and Menard limit pressure.
CU technical specifications:
» Dimension: 86 x 43 x 26 cm (tripod height : 65 cm).
» Mass: 24.5 kg (tripod 3.5 kg).
» Aluminium box with protection cover.
» Transport handle.
» Tripod and level allowing adjustment of verticality on all sites.
