Wille Geotechnik - Isotropic Triaxial testing System

Our Isotropic Triaxial Cell is a state-of-the-art device designed for advanced geotechnical testing of soil and rock samples under controlled isotropic stress conditions. This cell enables researchers and engineers to study the mechanical behavior of materials under uniform pressure from all directions, simulating realistic subsurface conditions encountered in engineering projects such as tunneling, excavation, and foundation design.

This series of Soil triaxial testing systems are designed and manufactured to perform stress path triaxial testing on soft rocks under different temperature conditions. Many tests require temperature controlling of specimen either for high temperature or for low temperatures and this requires new designed system which would be able to avoid any temperature gradient in sample during tests and make a unique constant temperature condition during tests.
