Crack injections are the best and most effective way to waterproof and fix dry and or currently leaking cracked foundation walls, without costly exterior diging. 

Kevlar / Carbon Fibre Staples

What are Kevlar/Carbon Fibre Staples

Various types of foundation movement


Foundation walls general move one of six different ways or a combination of a few.  Those six different movements are;


1) Inward movement due to sideways energies from soil pressure;

2 )Outward movement due to earth contraction caused by soil drying out during the hotter months of the year.

3)Opening or widening of a crack due changes in temperature, for example, freezing, thawing, or wet and dry conditions.

4)Closing of a crack due to changes in temperature;

5) Shearing of block stone or concrete due to shifting in load weight of the structure;

6) Sinking of the footing.

How Carbon Fibre works


Carbon fiber staples address all of these various types of foundation movement. It is important to understand how the carbon fiber staples work to create the best and most permanent crack repair possible. As concrete attempts to move, the load transfers to the carbon fiber staple and is distributed throughout the staple. The strength of the staple stops the movement and reinforces the damaged area.

Vertical cracks

For vertical cracks, the staples are installed perpendicular to the crack. As pressure pushes on the wall, tension pulls the staples and the load is transferred to the carbon fiber. For horizontal cracking, the staples are also placed perpendicular to the crack. Horizontal cracks are also a sign of shear movement. Shear movement is addressed by installing staples in a cross hatch or “X” pattern across the crack. This "X" pattern will arrest walls and prevent cracking in both shear and inward movement.

Weight-to-strength ratio

In terms of weight-to-strength ratio, carbon fiber is currently the best material that our civilization can produce. Far stronger and less bulky than steel, carbon fiber is transforming a broad range of industries, and waterproofing is one of them.

Amazing properties

Thanks to carbon fiber's amazing properties, basement structural repair is easier and more profitable than ever before. Whether the job calls for straps, staples, or whole sheets of material, there's a product on the market to fit your needs, and a manufacturer to back it up and make sure they will perform.

Highest tensile strength known to exist

Carbon fiber has one of the highest tensile (pull) strengths known to exist. Even under incredibly high tension, carbon fiber will not stretch or break, which comes in handy when repairing below-grade structural concrete. Whether it's used as sheets, straps or staples, carbon fiber can keep basement walls from bowing and cracks from expanding.

Kevlar staples were made with shear strength in mind and are designed to add a structural fix to your foundation wall crack repair.
