Deep vibro techniques
Deep vibro techniques offer flexible solutions for soil improvement. They are mainly used under foundations of structures to be constructed on soils of low bearing capacity. Keller developed the depth vibrator (patented in 1934), which was originally used to compact granular soils such as sand and gravel.
Chemical Grouting
Permeation grouting (cement grouting, chemical grouting, or pressure grouting) fills cracks or voids in soil and rock, permeating granular soils with flowable grouts to create a cemented mass.
Soil Improvement
Soil improvement refers to the practices aimed at enhancing soil quality and productivity through methods like soil treatment and structural enhancement, particularly crucial in arid and semiarid regions facing challenges such as soil cracking, pests, diseases, and nutrient scarcity.
Prefabricated Vertical Drains & Jet Grouting
Wick drains, also known as Prefabricated Vertical Drains (PVD) are prefabricated geotextile filter-wrapped plastic strips with molded channels.
Jet grouting improves the mechanical characteristics of the soil using a fluid jetting with very high kinetic energy that breaks up the soil structure and mixes the soil particles in-situ with a grout to create a homogeneous mass of high strength reinforced soil-cement material.
