Description

PERPENDICULAR Gorilla Wall Braces Kit

PERPENDICULAR Gorilla Wall Braces are used to straighten bowing basement walls that are PERPENDICULAR to the ceiling floor joists.

Each Gorilla Wall Brace comes as a kit that includes the floor bracket, top brace assembly, support brackets, and all the nuts, bolts screws, washers needed for installation. The required steel beam is NOT included.

REQUIRED STEEL BEAM IS NOT INCLUDED

Per our engineering testing specifications, Gorilla Wall Braces need to be installed every 32 inches or 48 inches along the bulging basement wall that you wish to straighten depending on the wall type (see specifications below).

An engineered floor bracket is included in each kit.

The bracket requires no removal of the concrete floor. NOTE: if the floor is too thin or deteriorated for the screw anchors to hold, cut out a 16″x16″ square in the basement floor where the brace would be located and pour a new concrete pad reinforced with rebar into existing concrete. 4″ depth (or greater) is required.

Written instructions to install Gorilla Wall Braces are included in each order, along with a link to a 12 minute online video to guide homeowners through the entire installation process. Instructions and video are copyrighted materials and only available after purchase of Gorilla Wall Braces.

STEEL BEAM SPECIFICATIONS…

Requirements for basement walls under 8′ high (and soil level under 7′) – 3 options:

• steel H-beam, 13 lbs per foot – W 4 x 13 lb (4.16″ x .280″ x 4.06″) A572/A992 Steel (choose 4″ idler)

H-beam at MetalsDepot

• steel I beam, 9.5 lbs per foot – S 4 x 9.5 lb (4.00″ x .326″ x 2.796″) A36/A572-50 Standard Steel (choose 3″ idler)

I Beam at MetalsDepot

• 2″ x 4″ tube steel at 1/4″ thickness (2” side goes against wall to ensure proper yield strength — choose 2″ idler)

Tube Steel Beam at MetalsDepot

Requirements for basement walls 8′ or higher (and soil level higher than 7′) – 2 options:

steel H-beam, 13 lbs per foot – W 4 x 13 lb (4.16″ x .280″ x 4.06″) A572/A992 Steel (choose 4″ idler)
2″ x 4″ tube steel at 5/16″ thickness (2” side goes against wall to ensure proper yield strength — choose 2″ idler)

We recommend I-beams/H-beams on block walls since they have more surface area and will more efficiently spread out the pressure against the wall, but 2″x4″ steel beams are an acceptable option in accordance with our engineering specifications.

BRACE SPACING SPECIFICATIONS…

Spacing requirements for Gorilla Wall Braces® based on our engineering specifications…

• 32″ spacing for 8″ block walls

• 48″ spacing for 10″ or 12″ block and poured basement walls (use closer spacing if basement wall is cracked in different directions)

If your basement wall has these conditions…

• cracked/crumbling blocks
• wall shear (the basement wall is shifted off a course of blocks – typically the bottom course)
• vertical cracking (not applicable to stair-step cracking in corners)
• tipping in from the top
• basement ceiling floor joists are soft/rotten
• for perpendicular braces – there is a walk-out on the opposite wall being braced (opposite wall needs to be supported by soil)

How to Measure Beam Locations…

PERPENDICULAR Gorilla Wall Braces
This is a precise measurement. Be sure to measure each brace location individually just in case there are irregularities in your concrete floor. Measure from the bottom of the floor joist to the floor and subtract 5/8″. That 5/8″ subtraction will accommodate the 3/8″ floor bracket your steel beam will sit on and give you 1/4″ clearance on top.
