Single-Component Systems
This suite of single-component, low-viscosity polyurethane formulations (formerly known as Terra-Lok) offers excellent soil permeation qualities. The closed-cell foam encapsulates loose soils to form a solid, water-tight barrier, stopping water intrusion and increasing load-bearing capacities.
How Single-Component Hydrophobic Foam Works
The Single-Component grouts are moisture-activated systems that are used to stop water infiltration or exfiltration by sealing joints and cracks. They are also used as permeation grouts to stabilize non-cohesive soils by essentially gluing them together. The hydrophobic system can be injected with a variety of different types of pumps and in some cases is packaged in caulk tubes for small-scale work. Reaction times are field adjustable by adding a catalyst to the grout before injections to speed it up, depending on your needs.
Applications
NCFI's Single-Component polyurethane products can fulfill a wide variety of geotechnical applications. A closed-cell foam system, it was specially formulated for permeation grouting and soil stabilization projects.

Benefits of Single-Component Polyurethane Systems
Environmentally Inert
NCFI's Single-Component products are NSF-61 Certified, making them safe for use near a potable water source. The cured product is inert and does not leach into the soil or groundwater.
Hydrophobic
The Single-Component product line consists of both Hydrophobic and Hydrophilic systems that are moisture activated.
Easy to Handle
The systems can be installed with a variety of pumps and offer a small equipment footprint, making it easier to use in difficult access sites.
Long-Lasting
Once cured, the foam is inert and built to withstand the test of time in challenging conditions.
