Prime-Flex Polyurethane Grouts - The Soil Stabilization Solution

(Click on Product Name for Technical Data)

 

In this extremely specialized field, grouts are used to fill voids and create sub-grade grout barriers in earthen dams, coastal seawalls, underground vaults and tunnel boring operations. A major advantage of chemical grouting is the ability to strengthen existing soils without the need for excavation or disruption of facility operations. As the popularity of trenchless technology continues to grow, engineers and contractors are finding that they can use chemical grout to solve a multitude of problems caused by poor soil or excessive water conditions.

 

*Prime-Flex polyurethane grouts are ideal for Manhole Rehab and Soil Probe Grouting.

Prime-Flex 900 LVSF*

Prime-Flex 900LVSF is a solvent free, hydrophilic, liquid polyurethane injection resin designed to seal leaks in concrete and masonry structures. When it contacts water, Prime-Flex 900LVSF expands up to 700% and forms a tough, flexible foam seal that cannot be penetrated by water. Prime-Flex 900LVSF is U.L. certified to conform to ANSI / NSF Standard 61 Drinking Water Systems Components - Health Effects.

 Product Info

 
 Grout Type Hydrophilic
 Viscosity 450 cps
 Cured Material Flexible Foam
 Catalyst No
 Expansions % up to 700%

 

Prime-Flex 900 XLV*

Prime-Flex 900 XLV is a hydrophilic, liquid polyurethane injection resin designed to seal leaks in concrete and masonry structures. When it contacts with water, Prime-Flex 900 XLV expands up to 600% and forms a tough, flexible foam seal that cannot be penetrated by water. Prime-Flex 900 XLV is U.L. certified to conform to ANSI / NSF Standard 61 Drinking Water Systems Components - Health Effects.

 Catalyst No
 Expansions % up to 600%

 


Prime-Flex Hydro Gel SX*

Prime-Flex Hydro Gel SX is a moisture-curing, hydrophilic polyurethane resin designed to stop leaks in below-grade structures. It reacts with water to form either a watertight foam or impermeable gel depending on the water to Hydro Gel SX mix ratio. This product is ideal for stopping leaks in manholes, sewer pipes and utility vaults. Prime-Flex Hydro Gel SX is U.L. certified to conform to ANSI / NSF Standard 61 Drinking Water Systems Components - Health Effects.

 Product Info

 
 Grout Type Hydrophilic
 Viscosity 500 cps
 Cured Material Flexible Gel or Foam
 Catalyst No
 Expansions % up to 400%

 


Prime-Flex 985

Prime-Flex 985 Rigid Foam is a two-component urethane resin that produces a strong, lightweight foam. Typical applications include filling wet voids, underslab sealing, and filling abandoned pipelines and storage tanks.

 Product Info

 
 Grout Type Two Component
 Viscosity 400 cps
 Cured Material Rigid Foam
 Catalyst No
 Expansions % up to 20:1

 

Prime-Flex 910

Prime-Flex 910 is a low viscosity, polyurethane injection resin designed to stabilize soil. When mixed with a catalyst and injected, it migrates through loose soil and into below grade voids. As it comes into contact with ground water, the Prime-Flex 910 begins to react and expands to form a rigid foam. The foam encapsulates loose soil, fills voids and forms a solid, water-tight barrier.

 Product Info

 
 Grout Type Hydrophobic
 Viscosity 40 cps
 Cured Material Rigid Foam
 Catalyst Yes
 Expansions % up to 2900%

 

Prime-Flex 920

Prime-Flex 920 is a liquid polyurethane injection resin designed to seal leaks and fill voids behind concrete and masonry structures. When mixed with a catalyst and injected, it migrates through cracks, loose soil and below grade voids. As it comes in contact with ground water, Prime-Flex 920 begins to react and expands to form a tough, rigid foam seal that cannot be penetrated by water. Prime-Flex 920 is typically used to seal gushing leaks, fill voids and stabilize soil.

 Product Info

 
 Grout Type Hydrophobic
 Viscosity 120 cps
 Cured Material Rigid Foam
 Catalyst Yes
 Expansions % up to 2900%
