We will then show you how we use Carbon Fiber straps with a super bonding epoxy to strengthen a block wall to stay in place.

Thanks for the new upload! Love all the knowledge I can get

@ChathamJackTar 2 года назад

You do a great job! Please keep the videos coming! In your method of dewatering, you protect structural integrity by preserving bearing along the edge of the basement slab, and you enhance drainage by deepening & widening your trench. I assume you have to be pretty careful to stay above the 45 degree 'safety cone' beneath the footing, or accidentally undercut it.

@AmericanDryBasementSystems 2 года назад

We never... never go below the bottom of the footer. We work parallel to the footer. Accidental over trenching is an amateur mistake.

Was there any signs above the basement with those large cracks like cracks in drywall sagging joists etc?

@aslo4812 Год назад

Do you have a video on retaining walls? They have to be similar right?

@ep411 4 месяца назад

These are awesome videos with great explanations. I have this exact problem in a home I am purchasing to flip. Any chance you can say approximately how much something like this costs and how long a project like this took??

@nathanb9057 3 года назад

I sure could use your help! I am over on the Oregon coast and I bought a house with an old basement in the walls have some cracking in it. Pretty sure there’s no existing drainage system around the foundation

@AmericanDryBasementSystems 3 года назад

The softer soil around your house is filling with rain water or from a water runoff. Hydrostatic pressure is so great it is cracking your walls with or without a system in place. The point of the video is that you need a drainage system that keeps the water level low around the house, thus minimizing pressure against the walls.

@shanewhite499 3 года назад

@@AmericanDryBasementSystems will an interior system that sits becide the footer relieve the pressure? How does the water actually get inside the system if it's outside? We have a interior system but I was just curious if and how it drains the water table outside

@heloc3 2 года назад

The carbon fiber adds strength. How does it prevent shearing at the top and bottom without anchoring it like you showed? Would have been great to show the entire fox even if speeded up. Thx for the videos.

@weirdmatter 3 месяца назад

They should have straightened that foundation out first.

@danicabonine5321 Год назад

Did you have to do any drainage work on the exterior of the basement to prevent any future movement of the walls? Or do you rely on the carbon fiber straps exclusively to keep the walls from moving under the pressure of the false water table?

@AmericanDryBasementSystems Год назад

No. The homeowners installed an exterior drainage themselves before calling us. Down the road, if water seeps in again, we will install an interior system. It is the only sure way to manage water seepage, or we would be in the exterior waterproofing business too.

Can Carbon Fiber be used on a bowing brick foundation wall? Also what are your thoughts on using high strength steel straps for a bowing brick foundation wall? Thanks.

@AmericanDryBasementSystems Год назад

Yes carbon fiber straps will work on brick walls. It is not effective on walls bowing more than two inches. Steel straps can be used but not my preferred choice.

@hippo-potamus Год назад

I have similar sized cracks going verticle 1cm in gap, will fiber bonding cement work to fix the joint? I was thinking of just using mortar but I think the fiber bonding cement will be superior, am i correct. Thanks for your reply. Cheers.

@AmericanDryBasementSystems Год назад

Fiber bonding cement works great with fiber material. Not made for cracks. Use epoxy instead.

@ericwatson3490 2 месяца назад

Was that an ayres basement system?

@4g63awdbeast 2 года назад

Is that just as strong as breaking out a core and installing several sticks of 5/8 rebar and then filling is completely back with structural load bearing grout. Basically making it a solid column. Ya the Carbon fiber straps have an insane tensile strength but tensile strength is pulling strength, rather than barring as the wall is pushing out because of the hydrostatic pressure the water is creating. Just curious is all. I did structural restoration for 13 years. Block walls are suppose to have rebar placed every 4 feet and the core completely filled.

@AmericanDryBasementSystems 2 года назад

We use to do it the way you describe it until carbon fiber came along. If the walls are not bowing out more than 2 inches Carbon Fiber Straps are up to the task. The installation is not as invasive and costs a lot less. If the walls are protruding more than 2 inches, rebar and carbon fiber straps are useless. Get a structural engineer to install subfloor wall anchors with jacks.

@4g63awdbeast 2 года назад

@@AmericanDryBasementSystems Thanks for the reply. What you described is also what we did as far as if the wall was protruding more than x amount of inches. We had many options for home owners and business owners as far as what their budget would allow.

@NattyNarwhaal Год назад

What type of mortar/cement do you use to fill in the joints?

@AmericanDryBasementSystems Год назад

Hydraulic cement was the best choice for this situation.
