The mining industry is evolving — demanding safer, more sustainable, and more innovative approaches to ground stabilization, water...

Understanding Liquefaction Liquefaction occurs when saturated soil temporarily loses its strength and stiffness due to an applied stress, such as an earthquake, causing it to behave like a liquid. This can lead to significant ground deformation and the failure of structures built on or within the affected soil. The Role of Polymers in Mitigating Liquefaction Various types of polymers are increasingly being recognized as effective solutions for addressing soil liquefaction. H

When it comes to lifting and leveling sunken concrete, two primary methods are commonly considered: polyurethane concrete lifting and mud-jacking. While both techniques aim to achieve similar results, polyurethane concrete lifting has several distinct advantages that make it far superior to mud-jacking. 1. _ Material Composition and Weight Polyurethane Concrete Lifting: Utilizes a lightweight polyurethane foam that expands to fill voids and lift the concrete. The foam's light

Hydro-fracturing of soils, particularly clay, involves injecting a pressurized fluid to create fractures within the soil matrix, improving permeability or enabling material placement. Using FillFoam™, a specialized engineered foam, this process becomes efficient, precise, and environmentally friendly. FillFoam™ is a lightweight, versatile foam with a cellular structure that offers excellent compressive strength and flowability. Unlike traditional fracturing methods, FillFoam

In the world of geotechnical engineering, every project presents unique challenges, from unstable soils to complex void-filling requirements. These challenges demand innovative, efficient, and sustainable solutions. Enter FILLFOAM™ , the cutting-edge resin-blown foam that’s transforming how engineers approach void filling and soil stabilization. What is FILLFOAM™? FILLFOAM™ is a pre-expanded, nitrogen-rich foam developed from air, resin, and a hardener. This eco-friendly mate

Mechanism of Polymer Injection Injection Process: The polymer is injected through small holes drilled into the ground. The depth and location of the injection points are carefully planned based on the soil's condition and the load requirements. Determining Injection Depth with DCP Testing: Dynamic Cone Penetrometer (DCP) testing can be used to identify the depth at which polymers should be injected. DCP testing involves driving a cone-tipped rod into the soil and measuring

Project:  Lift, level, and stabilize a concrete slab of approximately 1,730 square feet.​ Installer:  Purlift Inc.​ Engineering Firm:  CIMA Plus​ Architectural Firm:  Rubin Rotman Associés  Challenge  École Boileau faced significant structural issues due to floor settlement in two classrooms and a supply room. The floors had settled by approximately four inches, caused by the decomposition of organic matter beneath the structure. This resulted in a void of about two inches be

Project: 6,300 square foot police station with adjacent public security office and fire station had sunk up to three inches. Installer: PURLIFT INC. Challenge: The building was built in an area where there was a hill sloping away from the structure approximately 20 meters away. A number of factors had contributed to the slab having sunk, including one or more of the following: The type of soil the building was built on, clay. The land the structure was built on was slow

Project :  73,000 square foot shopping centre sunk up to 6”.    Installer :  Lève-Béton PURLIFT    Challenge :  The shopping mall was built in 2010 on a concrete structural 8” thick slab. A number of factors had contributed to the slabs having sunk, including one or more of the following:   The type of soil the mall was built on, grey clay.  The land the mall was built on used to be a marsh.  Train tracks close by whereby the trains are travelling at a high speed and create .
