Foundation Crack Injection Process

How We Fix Cracks Permanently

First, we inspect your foundation to determine crack type and severity. Not all cracks are the same, and the repair method depends on whether you’re dealing with settling, water pressure, or structural movement.

Next comes the actual crack injection. High-pressure polyurethane or epoxy gets injected directly into the crack, filling every gap from inside your basement wall all the way through to the exterior. This creates a waterproof seal stronger than the surrounding concrete.

Finally, we clean the area and inspect it to ensure the repair is complete. You’ll see immediate results – no more water seepage, no more growing cracks, and no more wondering if the problem will get worse.

Complete Foundation Repair Solutions

More Than Just Crack Filling

Every foundation crack repair includes a comprehensive assessment of your entire foundation system. Many Freeport homes have multiple small issues that need attention before they become major problems.

Our service covers both interior and exterior foundation work. Sometimes the best approach involves sealing cracks from both sides, especially when dealing with Long Island’s fluctuating water table levels.

You also get guidance on preventing future foundation issues. Simple drainage improvements or grading adjustments can save thousands in future repair costs, and we identify these opportunities during every job.

How long does foundation crack injection take to complete?

Most foundation crack repairs take 2-4 hours depending on the number and size of cracks. Simple hairline cracks can be sealed in under an hour, while larger structural cracks may require additional prep work and cure time. The injection material begins working immediately, but full cure strength develops over 24-48 hours. You’ll see water seepage stop right away, but you should avoid heavy water exposure for the first day to ensure the strongest possible seal.

What's the difference between DIY crack fillers and professional injection?

DIY products only seal the surface of cracks, while professional injection fills the entire crack from interior to exterior walls. Store-bought sealants typically fail within months because they don’t address water pressure behind the wall or foundation movement. Professional polyurethane injection expands to fill every gap and remains flexible as your foundation naturally shifts with seasonal changes. The materials used by contractors are also much stronger and designed specifically for below-grade waterproofing applications.

Will foundation crack repair work in Freeport's soil conditions?

Yes, but the repair method must account for Long Island’s unique challenges. Freeport’s proximity to water means higher soil moisture content and more foundation movement than inland areas. Professional injection materials are specifically chosen for coastal conditions and remain effective even with fluctuating water tables. The key is using flexible sealants that move with your foundation rather than rigid compounds that crack again when the soil shifts during wet and dry seasons.

How much does foundation crack repair typically cost?

Foundation crack repair costs depend on crack size, location, and severity. Simple injection repairs for small cracks typically range from a few hundred to several hundred dollars per crack. Larger structural repairs involving multiple cracks or extensive prep work cost more but are still far less expensive than foundation replacement or major water damage repairs. Most homeowners find that addressing cracks early saves thousands compared to waiting until water damage or structural issues develop.

Do foundation crack repairs come with any warranty?

Reputable foundation contractors provide warranties on crack injection work, typically covering the repair against water intrusion for several years. The warranty length depends on crack type and repair method used. Structural crack repairs often carry longer warranties than cosmetic crack sealing. However, warranties only cover the specific area repaired – new cracks in different locations aren’t covered since they result from separate foundation movement or settling issues.

When should I call for foundation crack repair versus waiting?

Call immediately if you see water seepage, cracks wider than a quarter-inch, or cracks that have grown recently. Horizontal cracks always require immediate attention since they indicate serious structural pressure. Even small cracks should be evaluated quickly in Freeport because coastal moisture accelerates foundation deterioration. Waiting rarely saves money since small problems become expensive ones, and water damage from delayed repairs often costs more than the original foundation work would have.
