SikaFix® HH LV

SikaFix® HH LV

Low viscosity, expanding, polyurethane chemical grout

SikaFix® HH LV is a hydrophobic polyurethane that, when used alone or with SikaFix® Accelerator, is designed to form flexible gaskets or plug joints and cracks in concrete from water infiltration.

  • Easy to apply, one component with accelerator.
  • Hydrophobic, only a small amount of water is needed for reaction.
  • Expands up to 30 times in volume depending upon the amount of SikaFix® Accelerator used.
  • Low viscosity permits injection into narrow hair line cracks.
  • Excellent elongation creates tight seal in moving cracks.
  • Tenacious adhesion to wet and dry surfaces.
  • Contains no volatile solvents.
  • ANSI Standard 61 potable water compliant
  • Non-corrosive

Product Information

Shelf Life

1 year in original, unopened container.

Storage Conditions

Store in a dry area between 40–90 °F (4–32 °C) using original re-sealable containers. Low temperatures will affect viscosity. To minimize this effect, store the product at room temperature for a minimum period of 24 hours prior to use. Material must be preconditioned to between 60–90 °F (16–32 °C) before use. If site temperatures are extremely low, heat bands or heated water baths may be used on the pails, before and during use to maintain the products temperature. Immerse only the lower 2/3 of the pails. Avoid splashing water into open containers. Do not use if ambient temperature is below 40 °F (4 °C).

Based on a 2.5 % SikaFix® Accelerator dosage, corresponding with the recommended 5 gallon: 1 pint ratio of SikaFix® HH LV to SikaFix® Accelerator, and a 0 % dosage, corresponding with no SikaFix® Accelerator added. SikaFix® Accelerator must be agitated by shaking the container prior to use.
Application steps

SUBSTRATE PREPARATION

When the crack is contaminated at the outside, it will be necessary to clean the crack surface so that the crack can be exactly located. If the crack is wide or high water flows are encountered, it will be necessary to seal the surface of the crack with a surface sealing material (SikaSet® Plug, Sikadur® 31 Hi Mod Gel, or open cell polyurethane foam saturated with SikaFix® HH LV). The surface sealing can be done before or after drilling the injection holes, depending on the particular situation.

MIXING

Prior to installation, the material should be agitated by vigorously shaking the 5-gallon pail or by mixing with a jiffy mixer, bung mixer or by hand. Prior to using SikaFix® Accelerator, the container should be shaken vigorously as the contents may settle during storage. For normal use, each 5 gallon unit of SikaFix® HH LV should be used with one pint container of SikaFix® Accelerator, a dosage of 2.5 %. The grout should never be used with more than 5 % SikaFix® Accelerator. Excess acceleration will cause vigorous expansion that is prone to shrinkage. Pour the desired amount of SikaFix® HH LV into a clean pail. Measure the appropriate amount of SikaFix® Accelerator and pour it into the SikaFix® HH LV and mix adequately.
