PLY Solutions Products

PLY Solutions is the eco-friendly and efficient solution for a wide variety of engineering and design challenges. Our patented foams are made from recycled materials, making them the “greenest” option on the market. They come in several densities and are formulated for different peak compressive and tensile strengths, expansion ratios, and reaction times. This customizability makes them versatile and suitable for various applications, such as high-density lifting, stabilization, void filling, and undersealing. Our foams have undergone ASTM testing and meet high standards for quality and performance. 

The below chart highlights the key metrics and ranges for our foam solutions.

The foam products in this line are made with materials that are environmentally  responsible, renewable, and recycled. The high biobased content of these foams has earned them approval from the USDA as Certified Biobased Products. Additionally, the recycled materials are treated with a catalyst that increases reaction times and decreases reliance on petroleum-based raw materials.

Hydrofoam Line

The Hydrofoam line is formulated with new raw materials that differ from those used in the Recycled Line mentioned earlier. These foams are specifically designed to set up in water, providing great dimensional stability without shrinking, a property known as hydro-insensitivity or hydrophobicity. Hydrofoam is ideal for sub-grade applications that are exposed to ground water, such as in Deep Foamjection™ techniques.

RR201, FAST, Lightning

Dual-Component, Polyurethane Foam

RR201 foam is a specialized product for residential concrete raising. This foam has a density of 2.5 lbs. per cubic foot, providing faster reaction times with less spread. With more control in the lifting process, RR201 foam is ideal for lifting concrete slabs in residential areas, including driveways, patios, pool decks, walkways, garage approaches, and sidewalks.

RR201 foam is designed to mimic the speed of traditional hydraulic Mudjacking, making it an efficient and reliable option for concrete lifting. For even faster results, RR201 Fast is available, offering the same great benefits as RR201 with increased speed.

Choose RR201 foam or RR201 Fast for a quick and effective solution for raising and leveling your residential concrete structures.

RR401, FAST, Lightning

Dual-Component, Polyurethane Foam

The RR401 Foam was created with a slower reaction time and greater spreadability, making it ideal for lifting larger slabs of concrete. It boasts more than three times the compressive strength of RR201, making it suitable for use in heavy lifting and high traffic areas. This foam also exceeds standard D.O.T. specifications for under-sealing projects. For those working in wet conditions, HF402 is a 4 lb foam option worth considering. Additionally, the RR401 Fast was developed to offer the same benefits as RR 401, but with a faster reaction time to better suit the needs of customers.

Applications
Benefits

RR501 - Slow Reacting Polyurethane Foam

Dual-Component

RR 501 is a two-component polyurethane foam that is designed to have a slower reaction time, allowing the material to spread more effectively. This feature makes it an excellent choice for under-sealing and stabilizing joints on rocking slabs that experience slab curl, as the foam can travel greater distances to address the issue.

Benefits

RR601 - High Density Polyurethane Foam

Dual-Component

The RR 601 is a dual-component, expansive polyurethane foam with an average reaction time and increased spreadability, providing greater control when lifting larger concrete slabs. Specifically designed for heavy lifting and high traffic areas, this foam surpasses typical DOT specifications for under-sealing and lifting projects.

Hydrofoam Line

HF402 & HF402 Fast

Dual-Component, Hydrofoam

Hydrofoam 402 is a dual-component, expansive polyurethane foam that has been developed for jobs that require a hydro-insensitive solution in the presence of water or moisture. With a density of 4 lb. per cubic foot, Hydrofoam 402 is designed to set up in wet environments while maintaining dimensional stability. It is suitable for use in a range of applications, including residential, commercial, and industrial.

HF402 Fast is a variation of Hydrofoam 402, formulated to offer the same benefits but with a faster reaction time to meet the specific needs of customers.

RR 600 Soil Stabilizer

Single-Component

RR 600 is a single component polyurethane with low viscosity that is specifically designed to stabilize and bind loose soils. This soil binder is ideal for use in a variety of applications, including stabilizing peat, loose sands, sea walls, concrete floors, foundations, and helical anchors.

FS201 Exterior Foundation Wall Spray

Dual-Component

FS 201 is a dual-component, 2 lb per cubic foot expansive polyurethane foam that is specially formulated for use as an exterior foundation wall spray. Its fast reaction time prevents dripping during application. This foam provides a moisture barrier for foundation walls, seals all cracks, and waterproofs the foundation. Moreover, it eliminates the need for tarring. With FS 201 foundation wall spray, sealing foundation walls can take as little as one hour, compared to the entire day required when using tar.

Benefits

FillFoam™ Void Filling Foam

Single-Component

FillFoam™ is a pre-expanded foam that is highly versatile and hydro-insensitive, making it ideal for use in various geotechnical applications. The foaming reaction does not generate heat, which allows FillFoam™ to fill voids and tanks of any size without issue. It can also be pumped over long distances to fill pipes and culverts.

Once cured, FillFoam™ is chemically inert and, when injected underground, it enhances soil bearing capacity. As a result, it is an excellent choice for lifting and leveling projects, such as airport runways and industrial buildings. Foam density can be easily adjusted on site, allowing the installer to tailor the foam to fit the specific requirements of any given application.
