100/800 High-Pressure Polyurethane Injection Foam 

NextStar 100/800 expands up to 25 to 30 times its initial volume, making it an ideal high-pressure injection material for the repair of leaking joints or cracks in concrete. As a hydrophobic polyurethane, NextStar 100/800 will maintain its physical closed cell form and is not subject to shrinkage. 

The system is comprised of a base resin along with an accelerator "B" component which must be mixed prior to injecting. Since Emecole 100/800 will not react until it comes in contact with moisture, the mixture can be prepared days before use, if stored in a completely dry environment.

Features:

  • Expands up to 25 to 30 times its initial volume.
  • The fast-acting reaction that can be controlled
  • Base resin requires the use of an activator "B" component.
  • Hydrophobic - not subject to shrinkage.
  • Medium viscosity.
  • Poured basement or structure cracks that actively leak water
  • Concrete walls where the crack is very small
  • Very small cracks as narrow as 0.002"
  • Great solution for previously unsuccessfully repairs

Use of Catalyst:

The reaction profile is adjusted prior to pumping by the addition of catalyst into the base resin and is affected by temperatures and the amount of moisture encountered. At 1.25% (1/2 pint per five gallons) the expansion will start in about 35 seconds and be complete in about 3.5 minutes after encountering water. At 2.5% (1 pint per five gallons) the expansion will start at about 25 seconds and be complete at about 2 minutes. These reaction times were determined at 77ºF with the addition of 2.5% water.

Where to Use:

Foundation Cracks that wont stop leaking Poured basement or structure cracks that actively leak water
Foundation Cracks that wont stop leaking Concrete walls where non-structural cracks are very small
Narrow loaking cracks in concrete Very small cracks as narrow as 0.002"
Foundation Cracks that have been repaired before Leaking cracks that have been previously unsuccessfully been repaired
leaks between new and old concrete construction Leaking cracks between new and old concrete pours

How to use:

Drill into place mechanical packers to allow injection into the tightest cracks Install mechanical packers to allow injection installed on opposite sides of the crack every 6 inches approximately
pre mix required polyurethane Premix needed amount of polyurethane and activator
Expanding polyurethane foam for high pressure concrete crack injection Using a High-Pressure pump or for one-time use or a modified grease tool
Fix previous bad repairs Start at the bottom and inject until the polyurethane starts to leak out 80% of the way to the next packer  
New Desgin that will not leak After completing the injection sometimes it is a good idea to reinject in any areas that did not foam up 

1 Gallon NextStar High Pressure Polyurethane 100-800 is specially formulated for use in active leaking small foundation cracks high-pressure injection.
