Helical Wall Ties

Pre-Existing Wall Ties
--- their failure can cause
cracking, leaning & bulging walls.

Masonry Wall Tie Anchors
--- 3/8" Stainless Steel Helical Wall Ties

The helical wall tie is a stainless-steel tie used to anchor building façades to structural members or to stabilize brick walls.

They are an economical solution that can be installed directly through the brick facade into various backup materials such as solid concrete, CMU block and even wood or metal studs.

The helical design allows the tie to be installed quickly and easily into a predrilled pilot hole (or embedded into mortar joints in new construction).  Installed, it provides a mechanical connection between a masonry façade and its backup material.

As it is driven, the fins of the tie undercut the masonry to provide an expansion-free anchorage that will withstand tension and compression loads.

The need for this type of reinforcement arises when pre-existing wall anchors were never installed, were inadequately spaced or have corroded away over time.

Job Site Installation ---- Easier & Faster:
--- Short, 3" Installation Tool (right)

Solid, 1-piece, 3" Installation Tool (right) -- versus a longer driver (below) Installs into SDS-Plus rotary hammer drills The small size enables contractors to secure the hammer drill using two hands The tool automatically countersinks the tie into the facade material With no moving parts and its short, solid steel 3" length, durability and productivity increase vs. the longer import driver.
Long Driver Tool (right):  10"+ length makes installations difficult as it requires the user to hold the drill with one hand while holding the driver.  Besides a higher cost, the multi-component drive includes a spring-loaded mechanism which often fails.

Key Features:

• Installs quickly and easily — with the rotary hammer in hammer mode, the tie installs faster than competitive products
• Smaller hole size provides an inconspicuous repair that preserves the appearance of the facade
• Installed, the tie is countersunk up to 1/2" below the surface, allowing the hole to be patched
• Larger core diameter provides greater twisting capacity, resulting in less deflection due to “uncoiling” under load
• Fractionally sized anchor — no metric drill bits required
• Patented manufacturing process results in a more uniform helix along the entire tie, allowing easier driving and better interlock with both substrates.

Installation:

A pilot hole is drilled through the façade material and into the backup material to the specified embedment depth + 1" using a 7/32" or 1/4" concrete drill bit.

Drill should be in rotation-only mode when drilling into soft masonry or into hollow backing material.

Position the blue end of the helical tie in the installation tool and insert the tie into the pilot hole.  With the SDS-plus rotary hammer in hammer mode, drive the tie until the tip of the installation tool enters the exterior surface of the masonry and countersinks the tie 1/2" below the surface. 

Patch the hole in the façade with a color matching color facade material or clear silicone. The small diameter hole allow the repairs to be efficient and inconspicuous.
