Foundation Crack Repair in Seattle

Looking Foundation crack repair in Seattle? Foundation cracks are a common issue for Seattle homes due to constant moisture, shifting soil, and seasonal ground movement. At Jet City Foundation & Construction, we provide expert foundation crack repair solutions designed to stop water intrusion, restore structural strength, and prevent further damage. Whether the crack is small or severe, early repair is essential to protecting your home’s stability and value.

What Causes Foundation Cracks in Seattle?

Seattle’s environment places unique stress on foundations, including:

• Heavy rainfall and high groundwater levels

• Expansive, moisture-retaining soils

• Soil settlement and erosion

• Poor drainage around the foundation

• Freeze–thaw cycles

• Hydrostatic pressure against foundation walls

Over time, these factors can cause cracking in concrete and masonry foundations.

Types of Foundation Cracks We Repair

Vertical Cracks

Often caused by concrete shrinkage or minor settlement. These cracks can allow water intrusion and should be sealed promptly.

Horizontal Cracks

Typically more serious and caused by soil pressure. These cracks may indicate structural stress and require professional reinforcement.

Diagonal Cracks

Usually related to uneven settlement or shifting soil beneath the foundation.

Hairline Cracks

While small, these cracks can still allow moisture intrusion and worsen over time if left untreated.

Our Foundation Crack Repair Services

Epoxy Crack Injection

Used for structural cracks, epoxy injection bonds the concrete back together, restoring strength and preventing further movement.

Polyurethane Injection

Ideal for active leaks, this flexible material expands inside the crack to create a long-lasting waterproof seal.

Carbon Fiber Reinforcement

For bowing or cracked foundation walls, carbon fiber straps provide strong, low-profile structural support without major excavation.

Surface Sealing & Waterproof Coatings

We apply professional-grade sealants and coatings to prevent moisture penetration and protect the foundation.

Drainage & Waterproofing Solutions

If cracks are caused by water pressure, we address the source with drainage upgrades and foundation waterproofing.
