Tie Hole Seal

The Sika X-Plug is a "patented" mechanical plug specifically designed to SEAL the void formed in a concrete wall by the removal of a taper tie rod or pass through tie sleeve. With the X-Plug's mechanical design, tightening of the stainless steel nut causes an expansion of the EPDM rubber plug, increasing its diameter inside the taper tie void. This action simultaneously compresses the main body plug onto the bolt to create a liquid-tight seal between the plug and the wall of the taper tie void.

The Sika X-Plug used with a taper tie system has proven to save contractors 50% in labor and materials costs when compared to alternative forming/sealing methods (i.e. She Bolts, non-mechanical plugs). The Sika X-Plug can be installed 6 times faster than non-mechanical plugs and ensures a positive seal unlike the competition. With the taper tie system, contractors are able to erect wall forms in a fraction of the time compared to a she bolt system that can lead to time consuming, costly leak repairs and corrosion of the inner coil rod.

The Sika X-Plug has the capability and reliability to seal taper tie voids without grout on either side of the plug to a head pressure rating of nearly 300 ft. There is no longer a need to use a non-shrink grout, water plug, epoxy, or bentonite rope in the taper tie voids as an added precaution.

The 304 stainless steel bolt is compression set at 50 lbs. into the rubber grommet, to prevent spinning during installation.

A Xylan coating is applied to the stainless steel bolt to boost the corrosive resistance an extra 500-1000 hours in the ASTM B1117 Salt Spray Test. The Xylan coating also serves as an anti-galling/anti-seizing agent.

* Consult a Sika Greenstreak engineer for compatibility of the X-Plug in your specific chemical environment.

Extreme Cold

At below freezing temperatures, Greenstreak recommends storing the product in a warm climate prior to installation to ensure maximum performance during installation.

For maximum performance and to ensure the proper size X-Plug is ordered, the contractor should pay close attention to tie placement/shifting. Greenstreak recommends that before taper ties are placed into the form work, all ties are pre set with the large wing nuts and plates set to a predetermined distance on the threads to allow the “large diameter” of the taper to land as close to the concrete wall as possible. This will ensure proper depth and plug placement for increased efficiency.

The X-Plug is suitable for use in many, but not all chemical containment applications.
