Foundation Crack Injection Process

Here's Exactly How We Fix It

First, we inspect your foundation to understand what’s causing the cracks. Not all foundation cracks are the same, and the repair method depends on what we find.

For most basement wall cracks, we use professional crack injection. We clean out the crack, install injection ports, and pump in specialized polyurethane or epoxy that bonds with the concrete. This creates a seal that’s actually stronger than the surrounding foundation.

For structural cracks, we might need additional reinforcement or different repair techniques. We’ll walk you through exactly what your foundation needs before we start any work. No surprises, no upselling, just the repair that actually fixes your problem.

Everything Your Foundation Crack Repair Includes

You get a thorough foundation assessment, not just a quick look at the obvious cracks. We identify the root cause, whether it’s settling, hydrostatic pressure, or structural movement.

Our repair work includes proper crack preparation, professional-grade injection materials, and exterior waterproofing when needed. We don’t just seal the crack – we address why it happened so it doesn’t come back.

Every job comes with a detailed explanation of what we found and what we fixed. You’ll understand your foundation better than most homeowners, and you’ll know exactly what to watch for in the future. Plus, all our work is backed by warranty because we stand behind what we do.

A large vertical crack runs through a concrete foundation wall beneath a wooden structure, with soil, grass, and a black pipe visible at the base.
Any crack wider than a quarter-inch needs professional attention, especially if you see water seepage or if the crack is growing. Horizontal cracks are more serious than vertical ones and usually indicate structural pressure. If you can see daylight through the crack or if it’s allowing water into your basement, don’t wait. Even smaller cracks can become bigger problems during freeze-thaw cycles here in Oakdale. When in doubt, get an assessment – it’s better to catch foundation issues early than deal with major structural problems later.
Professional crack injection creates a permanent seal when done correctly with the right materials. The polyurethane or epoxy we inject actually bonds with your concrete and flexes with normal foundation movement. However, injection only works if we address what caused the crack in the first place. If there’s ongoing water pressure or structural movement, we need to handle that too. That’s why we always assess the underlying cause, not just treat the symptom. A proper repair should last as long as your foundation.
Most basement crack repairs take 4-6 hours, depending on the number and size of cracks. Simple crack injection can often be completed in one day. More complex structural repairs might take 2-3 days if we need to install reinforcement or address multiple issues. The injection material needs time to cure, so you’ll want to avoid heavy water exposure for 24-48 hours after repair. We’ll give you a realistic timeline during our assessment so you can plan accordingly.
DIY crack fillers are surface treatments that might stop minor seepage temporarily, but they don’t create a structural bond with your foundation. Professional injection uses specialized equipment to force repair material deep into the crack under pressure, creating a seal from the inside out. We also use commercial-grade materials designed for foundation repair, not general-purpose caulks or fillers. The biggest difference is that we identify and address what’s causing the crack, while DIY approaches just cover up the symptom.
Foundation crack repair costs depend on the size, location, and number of cracks, plus whether we need additional waterproofing or structural work. Simple crack injection typically runs less than major excavation or wall replacement. We provide detailed written estimates that break down exactly what you’re paying for. Most homeowners find that professional repair costs significantly less than dealing with water damage, mold remediation, or major structural issues that develop when foundation problems go untreated.
Older homes in Oakdale often develop foundation cracks due to natural settling and our local soil conditions. Many small vertical cracks are normal and not structurally concerning. However, older foundations may have different repair needs than newer construction, and some older concrete can be more challenging to work with. The key is having someone who understands both older foundation construction and current repair techniques assess your specific situation. Age alone doesn’t mean your foundation is doomed, but it does mean you want experienced contractors handling any repairs.
