WallDefense Strap

WallDefense straps permanently protect block walls by reinforcing them with straps of carbon fiber. Because carbon fiber is many times stronger than steel and won't stretch, the wall is able to stand firm against the pressures that can cause it to bow in, even when changing soil conditions increase those pressures. When installed tightly against your foundation walls, WallDefense adds tremendous strength without adding bulk. Your walls stay straight and protected, and even finishing the walls isn't affected by this non-disruptive, permanent solution.


Permanently protects block walls from inward movement and bowing, guaranteed by warranty.

Prevents the disruption and expense of future wall failure and repair.

Uses straps made from stronger-than-steel carbon fiber-reinforced polymers.

Low-profile design doesn't affect basement finishing projects.

Quick, easy installation that won't disrupt your home.

Installation Steps


Clean and prepare surface of wall.


Apply epoxy primer to the strap application area.


Saturate each two-inch-wide strap with epoxy and apply to wall.


Slowly work each strap onto wall for maximum adhesion.

Why You Need It

After a home is built, changes occurring in the surrounding soil are the primary cause of foundation settlement and bowing or leaning foundation walls. Excess moisture increases the weight of those soils, causing them to push in harder against the walls. During colder months, frost can cause the soil to expand, putting even more stress on the walls.
