A crack in a basement wall not only detracts from the aesthetic appeal but, more critically, threatens the structural integrity of a home. MG Basement Waterproofing Yonkers, leveraging over two decades of expertise, employs a meticulous process to eliminate this threat. The company’s specialists first meticulously assess the crack to determine the underlying cause, whether it’s due to settling, hydrostatic pressure from soil moisture, or other environmental factors using polyurethane foam.Following the assessment, appropriate repair techniques are selected, with options ranging from epoxy injections, which fuse the crack walls together creating a robust, waterproof seal, to the installation of carbon fiber strips that reinforce and stabilize the area. Our Basement Waterproofing Yonkers company emphasizes the use of premium materials like polyurethane foam or hydraulic cement, ensuring a solution that not only addresses the immediate leak but also fortifies the wall against future issues, aligning the repair process with the property’s long-term wellness.


A basement’s floor integrity becomes compromised the moment a crack appears, not just marring its appearance but signaling potential underlying structural concerns. MG Basement Waterproofing Yonkers approaches these fissures with a systematic method involving an initial thorough examination to understand the crack’s origins—whether from simple settlement, changes in humidity, or more serious foundation issues. The cracks are then filled with concrete sealant

The choice of repair strategy is critical: for smaller cracks, a simple sealing using high-quality sealants might suffice, while larger breaches may require more complicated fixes, such as injecting polyurethane foam that expands within the crack, forming a solid, waterproof barrier. This dual approach, tailored to the specific situation, ensures a durable solution to basement floor cracks:

Cracks in a basement foundation signal an urgent call for professional intervention, as they can lead to significant structural and moisture problems if left unattended. MG Basement Waterproofing Yonkers specializes in adopting a strategic approach for foundation crack repair, ensuring that the foundation regains its original strength and integrity. Leveraging advanced techniques like polyurethane foam injection, which not only seals but also flexibly adapts to the movement of the foundation, the team ensures a durable repair that withstands the test of time and elements.

Understanding the complexity that foundation repairs entail, MG Basement Waterproofing Yonkers initiates each project with a comprehensive evaluation to identify the root cause of the crack, be it due to environmental stress, poor construction, or pressure from groundwater. This precise diagnosis allows for the formulation of a targeted repair plan using concrete:

  • Evaluating the foundation to pinpoint the exact cause of the crack.
  • Choosing the right repair method, whether it be urethane injection or another advanced technique.
  • Implementing the solution to not only repair but also prevent future cracking.

Frequently Asked Questions

Basement cracks often stem from two primary sources: pressure from soil moisture outside the basement walls and settling of the foundation over time. While soil’s excessive moisture applies lateral pressure against the basement walls, gradual settling leads to shifts in the foundation, both of which create stress points prone to cracking using cement and adhesive concrete.

Identifying cracks in your basement that demand repair often involves spotting any visible lines or fissures on walls or floors, usually signaling water penetration or structural damage. Another tell-tale sign is the presence of moisture, water stains, or a musty odor, indicating possible underlying leak with waterproofing.

Deciding on whether to handle basement crack repair as a DIY project or enlisting a professional primarily hinges upon the crack’s severity and your skill level. Minor cracks might be manageable for experienced DIY enthusiasts, but for extensive or structural damage, it’s wise to consult a professional using epoxy.

Ignoring a crack in your basement walls can lead to severe water damage from leaks, escalating the risk of mold growth and compromising the structural integrity of your home. Moreover, it can also pave the way for radon gas infiltration, posing a significant health hazard to residents.

The duration of repairing a crack in a basement wall can vary significantly, typically ranging from a few hours to a day. This variation largely depends on the size and severity of the crack, as well as the chosen repair method.
