 Trustindex verifies that the original source of the review is Google. We feel very fortunate to have found this company. I met with Mike regarding leaks in the basement. He assessed the entire house, gave me options and clearly explained the process. Everyone from Mike, to the secretary in the office to the workers were absolutely amazing. They did the work as promised, gave us a reasonable price, and left the place immaculate. We could not be happier with the results! This is a great family owned business. You can’t go wrong!

 Trustindex verifies that the original source of the review is Google. Mark took it upon himself to come to my home and examine my issue himself.  He is knowledgeable not only in basement waterproofing, but also in land grading, excavating and several other adjacent topics.  While it was concluded my issue was not foundation oriented, he did not hesitate to propose several other creative ideas to help address my issue.  He has a great disposition, and I would not hesitate to recommend his services to others.

 Trustindex verifies that the original source of the review is Google. I bought my house 24 years ago, and for 24 years I lived with water coming in to my finished basement. A few years back I hired another company to put in a French Drain System which never worked. As the storms got worse the water in my basement increased.  Because of my previous experience I was hesitant to hire another company until I read about ACM and met Mark who was highly recommended by my Home Service Company. Mark spent about 2 hours explaining the process, and what was needed. In February 2025 ACM put a extensive French Drain System  which included taking down the sheet rock walls, demoing tile and placing a membrane along the whole perimeter of the drain system. All of this work was completed in 3 days exactly what Mark said. The guys were professional, polite, and best of all they were careful to save my Radiant Heating System which was under the tile. Since the French Drain System was placed I have not had 1 drop of water coming into my basement.  I am very grateful to Mark's ACM Company, and was able to refinish my basement without fear of water damage. I highly recommend ACM Basement Water Proofing to all who are having water problems with their basement.

 Trustindex verifies that the original source of the review is Google. I chose ACM because of their "Best of Long Island" award, and I'm glad I did. Mark's crew (led by Joe) installed an interior French drain  and a sump pump in our basement. Six months later, we've had no problems with water. These guys know what they're doing.

 Trustindex verifies that the original source of the review is Google. My wife and I would like to say thank you to Mark and his team for their excellent work installing a French Drain in our finished basement. For years we had to worry about flooding if we got a large amount of rain in a short time. The entire staff was totally professional. knowledgeable, competent and efficient. They were clean and caring and after each day they protected the whole worksite. Without a doubt, we would recommend them for all your basement waterproofing needs.

He guided me to check baseboard and sure enough a broken valve was causing this leak. It's good to find someone to help a homeowner without rushing to take their money. It's good to find a honest business man

Signs Your Foundation Walls Need Carbon Fiber Straps

Many Long Island basements face unique challenges due to our mix of sandy soils, clay pockets, high groundwater, and coastal storms. Over time, these conditions can put extreme pressure on foundation walls.

If you live in Nassau County or Suffolk County, watch for these warning signs that your walls may need carbon fiber reinforcement:

Horizontal or stair-step cracks in basement walls
Walls bowing or bulging inward
Walls leaning or tipping near the top
Shearing, where the wall slides inward along the bottom row of blocks
Cracks widening after heavy rain or snowmelt

If you notice any of these in your Long Island home, it’s time to schedule a professional foundation inspection with ACM Basement Waterproofing.

Are Carbon Fiber Straps/Strips the Right Solution for My Foundation Issues?

Carbon fiber straps are an ideal solution for basement wall repair. Carbon fiber is an incredibly strong material (five times stronger than steel) and does not stretch. The installed straps adhere to your basement walls, acting as a permanent brace that strengthens the foundation, keeping the walls in place.

Whether carbon fiber straps are suitable for your home in Long Island depends on the extent of foundation wall intrusion. Most of the time, carbon fiber straps are the answer for bowed, tipping, or shearing foundation walls. To be certain, you need to have one of ACM’s foundation repair experts inspect your foundation.

Should I Repair or Replace My Foundation Walls?

If you want to straighten the foundation walls of your Long Island home completely, you will need to replace them, but that is a last resort as it is the most invasive, expensive, and often the most unnecessary option. In the vast majority of cases, foundation repair is the better option.

Foundation repair prevents further damage to your basement walls, keeping them strong and safe. Only in the most extreme cases is foundation replacement necessary.

Additional Benefits of Carbon Fiber Straps

Beyond being an effective foundation repair solution, carbon fiber straps offer additional benefits:

1. Longevity. The strength and durability of carbon fiber mean that your foundation straps will be as effective years down the road as they were when first installed.

2. No Maintenance. After installation, you don’t need to worry about the straps. They will continue doing their job on their own.

3. Simple Installation. Carbon fiber straps are installed on the inside of your basement walls, which means no excavation is required, and the installation process is much shorter.

4. Minimal Disruption. Carbon fiber strap installation involves little noise and makes little mess. Installation is fast and quiet compared to other foundation repair options.

5. Hidden Straps. The carbon fiber straps are thin and lay flush against the wall, so you can easily cover up or even paint over the straps, making them all but invisible.

Can You Install Carbon Fiber Strips Yourself (DIY)?

Some Long Island homeowners like to take on DIY projects around the house. If you are one of those people, should carbon fiber strap installation (foundation repair) be a project you take on? In short, no.

The first issue with DIY foundation repair is the low quality of the products and materials in do-it-yourself kits. These kits do not have the same durable, professional-grade materials ACM uses in repair jobs.

And, even if you were to get your hands on suitable materials, the repair products are only effective if installed correctly. ACM has been fixing damaged foundation walls in Long Island for decades, and this experience allows us to create permanent foundation repair solutions.

On top of that, if the DIY work fails to repair the foundation properly, the added costs of later professional repair, on top of your original DIY costs, mean that you save time and money by calling ACM first to install carbon fiber straps.

Step-by-Step Carbon Fiber Installation Process

When you choose ACM Basement Waterproofing for your Long Island carbon fiber installation, here’s what to expect:

Inspection & Measurement – We evaluate the extent of wall movement in your Nassau or Suffolk County home and determine strap placement.
Wall Preparation – We grind and clean the surface to ensure maximum bond strength.
Epoxy Application – Industrial-grade resin is applied to secure the carbon fiber straps to the wall.
Strap Installation – Straps are placed vertically along the wall to prevent further bowing or tipping.
Finishing – Straps lay flush against the wall, allowing for painting or finishing right over them.

Most Long Island installations are completed in a single day with minimal disruption to your home.

Fortress Stabilization Systems Invisibeam

When a basement wall starts to bow, shear, or tip, your Long Island home needs more than a patch. ACM installs ICC-Building Certified Fortress Stabilization Systems, a carbon fiber solution that corrects the problem for good.

Built on over two decades of engineering and testing, the Fortress system locks your wall in place along its full height. Think of a seat belt: anchors at the top and bottom of each carbon fiber strap pull the wall tight and hold it steady. With ACM installing Fortress straps, your foundation gets repaired right the first time.

Invisibeam is the carbon fiber strap system made by Fortress Stabilization Systems. Sold exclusively through Fortress, it carries a lifetime warranty and ICC certification, permanently stops bowing and tipping, and needs no maintenance.

What Does ICC-Building Certified Mean?

ICC-Building Certification means Fortress carbon fiber straps have passed accredited, independent testing and been proven effective, so your Long Island basement repair clears building code inspection without a problem. Fortress earned its ICC-ES certification through rigorous evaluation at the Structures and Materials Laboratory at the University of Miami, an ISO 17025 accredited facility.

Why Carbon Fiber Works for Long Island Homes

Long Island’s coastal climate, seasonal storms, and freeze-thaw cycles create constant stress on foundation walls. In many neighborhoods across Nassau County and Suffolk County, older foundations and shifting soil conditions make homes especially vulnerable to wall movement.

Carbon fiber is an ideal repair solution because:

It is five times stronger than steel and does not stretch.
It bonds directly to the wall, creating a permanent brace that stops further movement.
It installs on the inside of the basement, so weather delays are never an issue.
It works with block and poured concrete walls common in Long Island homes.

ACM Basement Waterproofing uses professional-grade carbon fiber systems engineered for the specific soil and moisture conditions found across Long Island.

Carbon Fiber vs. Other Foundation Repair Options

When it comes to repairing bowing or leaning basement walls in Long Island, homeowners have several options—each with its own advantages and limitations.

Carbon fiber straps are a permanent, low-maintenance solution that installs quickly and causes minimal disruption. Because they lay flush against the wall, they take up no usable basement space, making them ideal for tight areas. While carbon fiber prevents further movement, it does not push a wall back into place, so it’s best suited for walls with early to moderate bowing or leaning.

Steel I-beams provide exceptional strength and can straighten walls over time, but they are bulky and can intrude into the basement, reducing usable space. They’re often used when bowing is more severe and interior space loss is acceptable.

Wall anchors can pull a wall back toward plumb, making them a good choice for more advanced displacement. However, installation requires exterior excavation and more time, which can be challenging in tightly packed Nassau County or Suffolk County neighborhoods.

Full wall replacement is the most invasive and expensive option, involving complete removal and rebuilding of the wall. While it results in a brand-new foundation wall, it’s typically reserved for extreme structural failures where no other repair method is viable.

For most Long Island homeowners dealing with early to moderate wall movement, carbon fiber offers the best balance of strength, cost, and minimal disruption—keeping basements secure without sacrificing valuable living space.
