There are a few companies out there now promoting DIY carbon fiber installation kits. They make the process look really easy. I’m suggesting you give this a bit more thought before diving in.
One example video for DYI carbon fiber installation on the internet shows only a best possible case scenario. The wall is barely cracked, any bowing is not apparent, and the wall has no paint to deal with! Gee that looks so easy!
What will you do if you run into problems not addressed in the video, such as walls bowed more than half an inch? It is essential to also properly tuckpoint the walls but that isn’t addressed. What if these are settlement cracks instead of hydrostatic pressure cracks? Carbon fiber will not stabilize settlement problems. How would you know? What if the walls are wet? What is the correct spacing for the block thickness? Is there any adjustment for backfill dirt height? What about reinforcing window openings? What about shearing at the bottom? Cracking near the top? What about top wall anchoring if the wall is slipping at the top? What if the walls are painted? Carbon fiber will not bond well to paint! How do you get the paint off the walls? What if it’s lead paint? What about corner shearing? Tuckpointing methods and materials?
The epoxies used for this material set up quickly. You will not have a lot of time to waste installing it before it sets up. You must get it right the first time or you can have an expensive mess to deal with! What kind of support are these people going to provide with their kit? What kind of warranty are you really getting, especially if you don’t get it exactly right? What will they do for you if the wall fails or you have delamination?
The list goes on and on! Do you think you have all the correct tools, know-how and ability to install your own carbon fiber and get it right so there won’t be problems in the future? If so you are in the minority and I wish you the best of luck! Sometimes trying to save some money can end up costing you a lot more than just money. Think about it. Should you hire someone with decades of experience or try it yourself? Carbon fiber, even at DYI pricing, is really expensive if you don’t get it right.
