SikaFix® HH LV

• Conformity with LEED®v4 MR Credit (Option 1): Building Product Disclosure and Optimization - Material Ingredients

1 year in original, unopened packaging.

Store in a dry area between 4 and 32 °C (40 and 90 °F) using original re-sealable containers. Do not allow product to freeze. 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 temperatures ranging between 16 °C and 32 °C (60 °F and 90 °F) 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 4 °C (40 °F).

Dosage:

SikaFix® HH Accelerator

1 - 3 % Accelerator 10 - 30 mL (1.3 - 3.9 US fl. oz) can per L
(33.8 US fl. oz) of grout (typical)

Maximum: +82 °C (180 °F)

Maximum: +82 °C (180 °F)

Based on a 2.5 % SikaFix^® HH Accelerator dosage, corresponding with the recommended 18.9 L : 473 mL ratio of SikaFix® HH LV to SikaFix^® HH Accelerator, and a 0 % dosage, corresponding with no SikaFix^® Accelerator added. SikaFix^® HH Accelerator must be agitated by shaking the container prior to use.

SikaFix^® HH LV
1 L (33.8 US fl. oz) grout = approx. 25 L (6.6 US gal.) foam (typical free expansion)
1 L (33.8 US fl. oz) grout = approx. 2 - 5 L (0.5 - 1.3 US gal.) foam (typical contained expansion)
Dependent upon quantity of Accelerator used and variation in crack/void configuration, injection conditions and end use will influence the yield

Drill appropriate diameter holes based on packer type/diameter being used along the side of the crack at a 45° angle to intersect the crack midway through the substrate. These holes should be drilled alternately on opposite sides of the crack at approximately 150 - 600 mm (6 - 24 in) centres depending upon the crack width. This spacing can be adjusted to suit specific applications where necessary. Install injection packers into the drilled holes and tighten or position and secure injection ports.

It is always necessary to flush the drilled holes with water to remove debris and drill dust from the holes and crack. This will also insure that the crack is wet enough to react with the grout when it is injected into the crack.

When the crack is contaminated on the outside, it will be necessary to clean the surface so that the crack can be located exactly. 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^CA or a preformed open cell polyurethane foam cord saturated with SikaFix® HH LV: select material compatible with potable water where necessary). The surface sealing can be carried out before or after drilling injection holes, depending on the particular situation.

Prior to injection, SikaFix® HH LV should be thoroughly agitated by either vigorously shaking the 18.9 L (5 US gal.) pail or by mixing with a low-speed drill (200 - 300 rpm) and Jiffy or ‘bung’ type paddle until a uniform consistency is produced. If mixing, scrape the sides and bottom of the pail to ensure a complete mix is achieved.

Prior to using SikaFix® HH Accelerator, the can should be shaken vigorously as the contents may have settled during storage. For normal use, the grout should not be used with more SikaFix® HH Accelerator than the amount recommended in the Curing Time data. The grout should never be used with a SikaFix® HH Accelerator content exceeding 5 %. Excess acceleration will cause uncontrolled expansion which is prone to shrinkage.

Pour the desired quantity of SikaFix® HH LV into a clean, suitably sized mixing vessel and where SikaFix® HH LV Accelerator is being used, measure the amount of accelerator required and add into the SikaFix® HH LV and stir until adequately mixed. It is advisable to mix and inject just a part of the unit initially (1L [2 pints] would be approximate) to determine the rate of resin travel and confirm how much product can be used within its pot life.

Use SikaFix^® Pump Flush, a non-flammable solvent, to clean tools, lines and equipment of uncured product. Cured material can only be removed mechanically.
