Basement Crack Repair
Cracks in basement walls, floors, and around windows are some of the most common entry points for water intrusion. DBS Repair provides professional Basement Crack Repair solutions for wall cracks, floor cracks, window leaks, and pipe penetrations. Our durable repair materials flex with concrete expansion and contraction, preventing future failures while working alongside your perimeter drainage system to help keep your basement dry, protected, and structurally sound.
Every Crack Type Requires a Different Repair Approach
Water can enter your basement through even the smallest opening in the foundation. During your free inspection, DBS Repair identifies where the water is coming from and recommends the right basement crack repair solution for that specific entry point.
Vertical Wall Cracks
Vertical cracks are the most common type of crack found in poured concrete foundations. They often develop as concrete cures naturally or as a home experiences minor settlement over time. While these cracks may appear small, they can allow water to enter the basement when hydrostatic pressure builds up around the foundation. DBS Repair addresses these issues with professional basement crack repair using the FlexiSpan® system, a durable polymer solution that bonds to both sides of the crack and remains flexible to help prevent future water intrusion.
Horizontal Wall Cracks
Horizontal cracks are more serious because they often point to lateral pressure from the soil pushing against the foundation wall. In many cases, these cracks appear along with bowing or inward movement in the wall. DBS Repair looks beyond the visible crack to determine whether the wall also needs structural support, then recommends a basement crack repair solution that helps address both water entry and long-term foundation stability.
Stair-Step Cracks (Block Walls)
Stair-step cracks are commonly found in concrete block foundations, following the mortar joints in a step-like pattern. These cracks can develop as a result of foundation settlement or pressure from the surrounding soil. Because water can enter through multiple joints, effective basement crack repair requires sealing each affected area individually to help prevent moisture intrusion and protect the foundation from further damage.
Basement Floor Cracks
Floor cracks can allow water to enter the basement when hydrostatic pressure pushes groundwater upward from beneath the foundation slab. Unlike many wall cracks, these openings are continuously exposed to water pressure from below. For long-term protection, DBS Repair captures water at the crack and directs it into the perimeter drainage system, where it can be safely carried away from the home. This approach helps prevent water from reaching the basement floor while addressing the source of the problem.
Leaking Window Frames
Over time, the seals around basement windows can wear down and create small gaps that allow water to seep inside. To stop leaks at the source, DBS Repair installs a discreet drainage connection beneath the window that directs water into the basement waterproofing system. The area is then sealed with a durable polymer material to create a clean, watertight finish and help protect the basement from future moisture problems.
Pipe Penetrations and Cove Joint
Areas where utility pipes pass through the foundation wall and the cove joint—the point where the wall meets the floor are common places for water to enter a basement. To prevent leaks, DBS Repair seals these vulnerable areas or installs drainage components that capture water and direct it into the perimeter drainage system. This approach helps keep water out of the basement while working with the home’s overall waterproofing system.
Why Crack Repair Works Best With a Drainage System
Sealing a crack stops water from entering at that specific point. But hydrostatic pressure, the force of groundwater against your foundation, does not go away after crack repair. Water will find or create another entry point if the pressure is not relieved.
DBS Repair typically installs FlexiSpan® crack repair alongside the WaterGuard® perimeter drainage system. The crack is sealed to stop the visible leak. The drainage system relieves hydrostatic pressure along the entire perimeter, protecting the repaired crack and preventing new ones from leaking.
