Question 1

What Causes Foundation Cracks?

Accepted Answer

Foundation cracks develop for a variety of reasons, including soil settlement, hydrostatic pressure, seasonal freeze-thaw cycles, concrete shrinkage, and changes in groundwater conditions. As pressure builds around or beneath the foundation, stress is transferred to the concrete, causing it to crack. Once a crack forms, water will naturally follow that path, especially during periods of heavy rainfall or snowmelt.

Question 2

Are Foundation Cracks Serious?

Accepted Answer

Not all foundation cracks indicate structural failure, but any crack that allows water infiltration should be addressed promptly. Even small cracks can worsen over time as moisture enters the concrete, leading to expansion, erosion, and recurring leaks. Proper evaluation is critical to determine whether a crack requires interior sealing, exterior repair, or a combination of both.

Question 3

Interior Foundation Crack Injection

Accepted Answer

Interior crack injection is a common solution for foundation wall cracks that allow water seepage but do not require excavation. This method involves cleaning and sealing the crack from the inside using specialized injection materials that penetrate deep into the fracture. Once cured, the material blocks water pathways and helps restore the integrity of the concrete.

Interior crack repair is best suited for isolated wall cracks where exterior access is limited or unnecessary. When installed correctly, injection repairs provide an effective, long-lasting seal against water intrusion while minimizing disruption inside the home.

Question 4

Exterior Foundation Crack Repair Solutions

Accepted Answer

Exterior crack repair addresses the problem at its source by sealing the crack from the outside of the foundation. This approach typically involves exposing the affected area, preparing the foundation surface, and applying professional-grade waterproofing materials to prevent groundwater from entering through the crack.

Exterior repairs are especially effective for cracks that extend below grade or are exposed to consistent groundwater pressure.

By stopping water before it reaches the foundation wall, exterior crack repair provides an added layer of protection and is often recommended when groundwater conditions are severe or when cracks are actively leaking from the outside.

Question 5

Ground and Slab Crack Repairs

Accepted Answer

Cracks in basement slabs or concrete floors are often caused by settlement, shrinkage, or pressure from beneath the slab. While some slab cracks are non-structural, they can still allow groundwater vapor or liquid water to enter the basement. Proper slab crack repair focuses on sealing the crack, stabilizing the surrounding area, and preventing moisture migration through the concrete.

DryCore assesses slab and ground cracks to determine whether they are isolated surface issues or part of a broader groundwater concern. In cases where slab cracks are linked to hydrostatic pressure, additional drainage or water management solutions may be recommended to prevent future movement or leakage.

Question 6

Choosing the Right Crack Repair Method

Accepted Answer

The correct crack repair method depends on crack location, size, activity level, and groundwater conditions. Some cracks can be resolved with interior injection alone, while others benefit from exterior repair or supplemental waterproofing measures.
