Kevlar Necktie Top Wall Anchoring System
Fortress Necktie DESCRIPTION:
Fortress Kevlar Necktie is an Aramid Composite webbing combined with an aluminum bracket and zinc-coated lags that laminates into 4020 epoxy resin system. Half of the Aramid webbing is traditional fabric, and the other half is Pre-Preg pre-cured with peel-ply which laminates to the foundation assuring the entire strap will load in conjunction. It is designed to attach to the bond or ridge plate of the structure which remains constant whether there is a sill plate or no sill plate present.

HOW IT WORKS:
Load at top of wall is tensile and then becomes shear. The bracket is held by 4 lags that have pull-out tensile in wood 9 times standard penny nails, lamination technique with vacuum clamping pulls Kevlar tight and reduces elongation. The load is then transferred to epoxy resin to a non-laitance bearing surface. Kevlar in epoxy matrix produces a lap shear of 750 psi. The necktie can be laminated over Fortress straps or independent of strapping.
WHY THE TOP WALL ANCHORING SYSTEM?:
Prior to the Kevlar Necktie, retrofit foundation repair methods were obtrusive, and heavy and many other elements had to moved such as pipes, ductwork, etc. Also, these foundation and basement wall repair methods interfered with ceiling height and in many cases affected the value of the property. After the Fortress Kevlar Necktie is attached and the insulation is reinstalled between the foundation joist pockets, the Necktie is virtually unseen.
The Fortress Necktie will permanently repair top wall concrete foundation movement. The process is fast, and easy and on most occasions can be done in one day with little disruption to your life. The Fortress Kevlar Necktie has been tested both in the field and by an independent engineering firm. Trust the results to protect the value of your home.
The Fortress Kevlar Necktie can be used in conjunction with other Fortress Stabilization System products to better fix concrete cracks and moving foundations permanently.
