JET GROUTING SOLUTIONS

In the realm of soil improvement, jet grouting stands out as a pivotal technique. This process involves mixing soil in-situ with injected cement grout to create a cement-stabilized soil column. The resulting soil offers increased strength and reduced permeability, making it an ideal engineered solution for foundation support and groundwater control. Typical applications include underpinning existing structures and forming cutoff walls for excavation support.

This method involves drilling a small-diameter pipe, approximately 4 inches in diameter, to the desired depth. Contractors then inject cement grout at high pressures, around 6,000 psi, through the drill pipe. This grout mixes with the soil as the pipe rotates and withdraws, forming a circular column of improved soil. The diameter of these columns can be adjusted by altering the withdrawal speed, offering flexibility in the support structure. These columns can either provide vertical support individually or be arranged in a pattern to create a barrier against soil and water movement.

Jet grouting is especially advantageous in areas with subsurface utilities or other buried obstacles. The technique’s minimal drilling requirement allows for easy navigation around these obstructions, facilitating the creation of larger diameter soil columns in tight spaces. This makes jet grouting a particularly efficient and effective method for soil stabilization in complex underground environments. Schnabel, as a leading jet grouting construction company, leverages this technique to deliver customized solutions for diverse construction challenges.

AN INDISPENSABLE PARTNER FOR CLIENTS WITH COMPLEX PROJECTS THROUGHOUT THE UNITED STATES.

Children’s Hospital in Minneapolis

Schnabel used jet grout columns as underpinning and excavation support for the construction of an addition to the Children’s Hospital in Minneapolis, Minnesota. The jet grout columns eliminated the need for timber lagging and prevented the loss of sand during the 21-foot-deep excavation.

J Avenue Water Treatment Plant

Schnabel installed 67 jet grout columns to support the expansion of the J Avenue water treatment plant in Cedar Rapids, Iowa. This project required an excavation adjacent to an existing structure. The continuous wall of jet grout columns was successful in retaining the soil and water behind the wall and no measurable settlement of the tank structure occurred.

The Minneapolis Children’s Hospital project was Schnabel’s first application of jet grouting to underpin an existing structure in lieu of traditional hand-dug underpinning pits. The project team was very pleased with the performance of the jet grout underpinning system.
