Lanham, MD Basement Waterproofing Contractor

A homeowner in Lanham, MD was experiencing persistent water intrusion in the attached garage of their colonial-style home, a common issue in Prince George’s County where poor drainage and aging concrete can allow water to collect near the foundation. After a free waterproofing inspection in Lanham, MD, our team determined that the existing concrete and lack of proper drainage were the root causes. To provide a permanent solution, NV Waterproofing and Foundation Repair removed the failing concrete, applied high-performance waterproofing membranes to protect the foundation, and repoured the surface for durability. We also installed a properly sloped trench drain system to redirect water safely away from the home. The result is a dry, protected garage and a long-lasting waterproofing solution in Lanham, MD that prevents future water intrusion.

Job Stories From Lanham, MD

Concrete sidewalk leveling in Lanham, MD

A homeowner in Lanham, MD recently reported an uneven sidewalk, presenting a potential hazard just before expecting holiday visitors. Caused by shifting soil, this issue was not just about aesthetics but also about safety and functionality. They reached out to NV Waterproofing and Foundation Repair to seek a professional evaluation and a durable solution. Our process began with a consultation through our Customer Care Specialist, followed by an on-site inspection conducted by our System Design Specialist. The inspection confirmed that soil voids under the concrete slab led to the misalignment and lifted sections of the sidewalk. Our expert recommendation was to employ the PolyLevel® and NexusPro® solutions. Our production team, consisting of a foreman and skilled installers, arrived at the site ready to tackle the issue. Using the PolyLevel® system, we drilled small holes into the affected slab. We then injected high-strength polyurethane foam, which expanded to fill the voids underneath and elevate the concrete back to a stable, level position. To finalize the procedure, NexusPro® Joint Sealant was applied. This top-of-the-line sealant effectively closed off the joints and cracks, protecting against water ingress, which can undermine soil integrity over time. Upon completion, the homeowner’s sidewalk was not only even and safe to use but also aesthetically pleasing for upcoming celebrations. Our efficient, minimally invasive approach ensured that the property was left in pristine condition, demonstrating our commitment to providing both remarkable customer experiences and long-lasting solutions in Lanham, MD.

Foundation Repair in Lanham, MD: Stopping Horizontal Cracks with the PowerBrace™ System

In Lanham, MD, a homeowner noticed widening horizontal cracks along their basement walls—classic warning signs of foundation failure. Worried about long‑term structural damage, they turned to NV Waterproofing & Foundation Repair, the trusted local expert in foundation repair in Lanham, MD.

Our process began with a quick call to our Customer Care Specialist, who arranged a complimentary, on‑site inspection. When our certified System Design Specialist arrived, a detailed evaluation confirmed serious inward bowing and wall instability. The best course of action: install our patented PowerBrace™ Foundation Wall Repair System for immediate stabilization and long‑term protection.

Installing the PowerBrace™ System

Led by an experienced foreman, our production crew custom‑cut each zinc‑plated steel beam to match the exact height of the basement. Heavy‑duty brackets secured the beams at the slab floor and the first‑floor framing, delivering instant reinforcement without messy excavation or disruptive hammering.

Because PowerBrace™ can be torqued over time, the system not only halted further wall movement but also offered the potential to straighten the walls gradually—an advantage few other solutions provide.

Results That Restore ConfidenceBy the end of the installation, the cracks were firmly contained and the foundation walls stood strong. We left the basement spotless, and the homeowner felt immediate relief knowing their home was safe, stable, and protected against future shifting soils and hydrostatic pressure.

Foundation Repair in Lanham, MD

Recently, a homeowner in Lanham, MD, contacted us, concerned that their house wasn’t quite right. Their floors had started to resemble gentle slopes rather than flat surfaces, and their walls didn’t stand as straight as they used to. Understandably worried about the safety and integrity of their home, they reached out to us for help. Our process started with an initial call to our friendly Customer Care team, who quickly scheduled an in-home inspection. Next, one of our experienced System Design Specialists dropped by to take a closer look. They identified the root of the problem: The foundation was settling more than it should, causing the unsettling slopes in the floors and the leaning walls. Our recommended solution? Installing Push Piers—a reliable system designed to stabilize the foundation by transferring the weight of the home to more stable, load-bearing soils far below the surface. Armed with a plan, our production team, including a talented foreman and skilled installers, got to work. Despite the complexities posed by the shifting foundation, the team expertly installed the Push Piers, taking care not just to correct the current issues but to secure the home's future as well. They worked diligently, keeping the job site clean and causing minimal disruption. By the time we had finished, the homeowner's floors had returned to their original flatness, and the walls stood tall and straight once again. More importantly, the homeowner gained peace of mind, knowing their, and their view, was sitting secure on a stabilized foundation. The successful project in Lanham, MD, showcases our commitment not just to solving immediate problems but to offering long-lasting solutions that bring peace of mind to our customers.
