When soil settles, the main issue is the inability of the sub-grade to support the slab or ground above. The job of the sub-grade is to have enough bearing capacity to support the slabs evenly.
Deep Foamjection™ is the process of injecting a two-part polyurethane foam into de-stabilized soils. The polyurethane foam is injected as a liquid and pushes out and into weak soils. This expansion will take the path of least resistance as it travels through the ground. The expansion will follow voids, fissures or weak/loose soils. As the foam travels, it takes the shape of a tree root. This volume of expanded foam increases the strength and density of the failed soils and adds a solid installed volume of polyurethane foam.
Deep Foamjection™ Foam is the foam of choice for sub-grade repair. It is a heavy-duty polyurethane foam specifically designed for jobs where water or moisture is present. This polyurethane foam was designed to be set up in the presence of water and to maintain its strength in wetter environments. Deep Foamjection™ Foam can also be used in various applications such as foundations, warehouse footings, tracks, bridges, crossings, culverts, posts & anywhere a weak sub-base is present.
The slower reaction time makes Deep Foamjection™ Foam great for Deep Foamjection™, allowing the material to spread further before curing. As foam reacts, it will follow vein fissures and voids. This custom-installed solution makes soil stronger.
Polyurethane Foam Characteristics
HMI manufactures a variety of polyurethane foams with different reaction times and strengths. Each is designed for your specific application.
Health Effects: • Polyurethane foam is made of fully reacted polymers and is considered a non-hazardous material per OSHA 29 CFR1910.1200.• The main adverse health effects of cured polyurethane are related to dust generated by sanding, grinding or cutting the cured foam. Like sawdust or other fine powders, dust from polyurethane foam may irritate respiratory organs, eyes, and skin. When fabricating or cutting polyurethane foam, protective gloves, eye protection, and a dust mask should be worn. • Is not listed as a carcinogen (NTA, IARC, OSHA).
Ecological Information: • Not a marine pollutant. • Will not bio-accumulate. • No mobility within the soil.
Disposal: • Can be disposed of as regular industrial waste, complying with local, provincial and federal regulations.
