OBIC 2020 UltraSeal

Typical Use

OBIC 2020 UltraSeal is a moisture activated, expanding, semi-rigid hydrophobic polyurethane foam. Designed with soil permeation in mind, typical uses include:

  • Filling large voids on the exterior of below-grade structures
  • Stopping leaks in below-grade structures
  • Stopping high pressure/high volume leaks due to its fast reaction and high expansion properties

OBIC 2020 UltraSeal requires the use of OBIC 2020C UltraSeal Conditioner. OBIC 2020C UltraSeal Conditioner is added to OBIC 2020 UltraSeal before it is injected into substrate. OBIC 2020C UltraSeal Conditioner enable OBIC 2020 UltraSeal to react with water accordingly. A minimum of ½ container and as much as 2 containers can be added to adjust the reaction time as desired.
