Jet Grouting<\/h2><\/div>

Jet Grouting is one of the deep soil mixing technologies using a cement-based binder.<\/strong><\/h3><\/div>

The process involves inserting a rotating drilling rod equipped with a jetting monitor into the ground, through which cement grout is injected at very high pressure (20\u201340 MPa). The high-energy grout jet disrupts the soil structure and mixes with soil particles. After hardening, a homogeneous material with strength parameters higher than the native subsoil layers is formed, known as soilcrete. The technology enables the construction of columns with diameters exceeding 1500 mm, as well as elements shaped as circular segments.<\/p>\n<\/div>

Advantages of Jet Grouting technology<\/h2><\/h3><\/div>

Design flexibility<\/strong> \u2013 the column diameter can be adjusted by modifying jetting parameters such as injection pressure, lifting rate, and rotation speed.<\/p>\n

Minimal space requirements<\/strong> \u2013 the process requires limited working space due to the small equipment footprint and reduced operating height.<\/p>\n

Suitability for works near existing structures<\/strong> \u2013 columns can be installed in direct contact with reinforced concrete or masonry structures.<\/p>\n

High execution efficiency<\/strong> \u2013 the technology allows the construction of large-diameter columns using relatively small boreholes.<\/p>\n

Geometric precision<\/strong> \u2013 the ability to form partial column sections by directing the jet at a defined angle without full rod rotation, enabling more accurate shaping of the soil improvement zone.<\/p>\n<\/div>

Environmental efficiency of Jet Grouting technology <\/i><\/h2><\/div>

    \n
  • An innovative spoil recovery technique enables a significant reduction in cement consumption<\/strong> and the use of natural resources on site. This decreases the demand for new mineral aggregates and reduces the environmental footprint associated with cement production and transportation.<\/li>\n
  • Jet Grouting also reduces the volume of spoil requiring disposal and limits the transport<\/strong> necessary for its removal, resulting in lower CO\u2082 emissions, reduced fuel consumption, and minimized logistical disturbance to the surroundings of the project site.<\/li>\n<\/ul>\n<\/div>
