SikaFix® Kit CA

Minimum substrate temperature is +5 °C (41 °F).

The Sika® Injection T can be left in place or cut with a utility knife.

Starting from bottom of the crack and using a glue gun or silicone, install Sika® Injection T’s ports at 100 - 150 mm (4 - 6 in) intervals. For wider cracks, the interval between each injection port can be increased to 150 - 200 mm (6 - 8 in ). Ensure each port is centred across crack and port is ready for injection. In order to prevent the injection ports to be accidentally clogged, they should be temporarily plugged using the plastic plugs that are supplied with the kit.

For cracks, joints, or voids less than 6 mm (1/4 in) wide, create a ‘V’ notch at least 6 mm (1/4 in) wide and 13 mm (1/2 in) deep using an angle grinder, disc cutter or sharp, hand chipping tool. Clean all cracks well with a wire brush to remove all dust, laitance (thin cement film), curing compounds, loose, friable, and foreign particles, grease, and any material which would obstruct bond of mortar and penetration of grout. Proceed to a final dusting of the crack before starting the injection process. Substrates should be clean, and sound and moisture must be present to bond the mortar and activate the grout.

To plug the crack, you need to wet it thoroughly with clean water to ensure adhesion of Sikaset® Plug. Surfaces must be saturated but clear of standing water when plugging mortar is applied. Mix Sikaset® Plug powder with clean, cold water in ratio of 1 part water to 3 parts powder by volume and to the consistency of stiff putty. Apply immediately a layer of mortar of 6 mm (1/4 in) around Sika® Injection T’s ports and 3 mm (1/8 in) along the complete face of the crack.

Note: Mortar dries rapidly (1 1/2 - 2 minutes) so it is recommended that it is mixed and applied in manageable quantities (proceed by mixing small batches). Allow the quick set, plugging mortar to set and harden 90 to 120 minutes before injecting.

Hydrophobic - only a small amount of water is needed for a reaction.

IMPORTANT: Thoroughly pre-wet crack with clean water to ensure Sikafix® PU will expand and form a sealing foam, as required. SikaFix® PU MUST BE IN CONTACT WITH WATER IN ORDER TO REACT AND EXPAND.

Remove any temporarily placed plugs from ports and insert tip of cartridge nozzle into lowest Sika® Injection T’s (No. 1) to start injecting. Pull the trigger of the caulking gun 3 to 4 times and then stop, in order to allow SikaFix® PU grout to penetrate and to expand in the crack. Should there be no sign of water displacement after 4 to 5 minutes, repeat the injection (3 to 4 pressures on the trigger) through the same injection port. Once all water is displaced, SikaFix® PU will fill up part of the crack and the partially expanded resin will come out from the next Sika® Injection T’s up (No. 2). When resin starts to flow out from Sika® Injection T’s No. 2 placed above, insert a plastic plug into the first Sika® Injection T’s (No. 1). Inject grout into the second Sika® Injection T’s (No. 2) by pulling the trigger 3 to 4 times until partially expanded resin starts to come out from the following Sika® Injection T’s (No. 3) located above. Place plastic plug into Sika® Injection T’s No. 2 and continue in the same manner until all Sika® Injection T’s ports have been injected and securely plugged to prevent leakage of unreacted grout resulting in unfilled cracks. After three (3) to five (5) hours, the excess of SikaFix® PU that came out to the surface of cracks (outside foundation walls) will be easily removed using a sharp utility knife.

Note: SikaFix® PU is a two-component material conditioned in a single, compartmented cartridge. The cartridge design and the material reaction occurring upon mixing may give the impression to the applicator that only half of the grout has been dispensed, where in fact, all the material has been extruded and applied.

Complete kit supplied no other materials needed. It does not require specialized equipment.

The Water Absorption is 0.19 kg/m.

Yes, cured foam should be protected from sunlight.

Unscrew threaded cap from SikaFix® PU cartridge and then remove plastic plug. Both cap and plug must be kept if not using all grout in cartridge at once. Attach the static mixing nozzle supplied and replace the threaded cap over the nozzle. Screw cap tightly to prevent leakage. Load the cartridge into a suitable caulking gun. When injection work is completed, remove threaded cap and the static mixing nozzle. Replace plastic plug and cap to allow future use.

Yield : Typical crack: 2.4 m (8 ft) long x 200 mm (8 in) deep x 3 mm (1/8 in) wide.
