Geotechnical injection systems used for slab lifting, deep injection and cavity filling, play a crucial role in stabilizing and reinforcing soil. These systems are designed to improve the load-bearing capacity and overall stability of the ground, making them highly effective for addressing issues such as subsidence, uneven settling, or weak soil conditions. ACOCHEM also provides specialized solutions for consolidating disturbed strata and rock formations, particularly in challenging environments such as tunneling and mining projects.

Geotechnical Injection: PURINJECT & GEORESIN
ONE-COMPONENT
A one-component PU injection system used for soil stabilization requires wet soil to trigger a reaction. Due to the very low viscosity the resin is suitable for permeation grouting.
PURINJECT 1C SOIL polyurethane injection system is a one component solvent free, very low viscosity pre-polymer ideally suitable for soil stabilization. Fast curing and excellent mechanical strength.
TWO-COMPONENT
Two-component injection systems consist of a resin and a hardener. A dual component pump or reactor is essential for geotechnical applications such as slab lifting, deep injection and cavity filling. It ensures that resins are mixed in precise ratios, injected under controlled pressure and temperature with a continuous supply to the required areas.
GEORESIN 035 is a structural two component polyurethane foam which - injected into voids beneath concrete slabs, walkways, foundations, walls, etc. - stabilises the underground and lifts it to the desired height without excavation. Free rise density: 30-40 kg/m³
Same system available with higher viscosity. Contact ACOCHEM for more information.
GEORESIN 055 is a structural, two-component polyurethane foam that, when injected into voids beneath concrete slabs, walkways, foundations, walls, and similar structures, stabilizes the substrate and lifts it to the desired height without requiring excavation. Free rise density: 40-60 kg/m³
Same system available with higher viscosity. Contact us for more information.
GEORESIN 035 CF (Cavity Filling) is a structural, two-component polyurethane foam system, designed for undersealing and void filling under concrete slab sections. The slow speed reactivity profile allows for excellent flow characteristics when used as an undersealing and void fill material. It will run and level itself and expand slowly with low heat. Free rise density: 30-40 kg/m³
GEORESIN
for slab lifting & cavity filling
Slab lifting is a technique used to raise and support sunken or unstable concrete slabs. By drilling holes and injecting a polyurethane resin to fill the voids below, the slab can be lifted to its original or required position.
Cavity filling is a technique used to fill voids or empty spaces within a structure and add structural support.
WHY GEORESIN?
Minimal disruption
Fast and durable alternative to traditional methods, restoring slab - soil contact and supporting heavy loads in just 30 minutes.
Economic solution
Cost-efficient as it eliminates the need for costly concrete repair and removal. Reduces labour and minimizes downtime.
Long lifetime
Highly durable with a long life span forming a strong bond that withstands heavy loads, reducing future maintenance needs.

Geotechnical Injection:
ACRYLINJECT
ACOCHEM's acrylic based resins are extensively used in geotechnical applications for soil stabilization and consolidation works. The ACRYLINJECT system contains 3 components: a resin, a catalyst and an initiator. Adding a 4th component, a liquid polymer, improves the dry-wet cycles and brings higher mechanical properties.
Non-toxic, methacrylate based injection system for sealing and consolidation works in presence of water used in the following applications: water shut off, plug and abandon well applications in oil and gas sector.
Methacrylate based injection system for sealing and consolidation works in presence of water. In wet conditions, the volume of the gel increases and decreases in a reversible manner assuring perfect soil consolidation by gel encapsulation.

Geotechnical Injection:
SILINJECT
Urea-silicate based resins are a type of grouting material that is commonly used in mining and civil engineering applications. These resins are formed by mixing PU and silicate minerals (also know as waterglass), in a specific ratio.
Organo-mineral, non-flammable two-component foam for tunneling and mining suitable for filling cavities in concrete strata, consolidation of fractured rock and stabilization of cavities and tunnels.
Non-foaming, fast-curing, elasticized 2 component silicate injection resins for hardening fissured and fractured mountainous zones in tunneling and mining.
Non-foaming, fast reactive, two component silicate injection system for anchor bolting and roof support.
