Common Concrete Problems and How to Fix Them in Hillsboro, OR

Concrete is a durable and long-lasting material, but like any building material, it can develop issues over time—especially in areas like Hillsboro, OR, where weather conditions fluctuate throughout the year. At Evolution Contractors, we specialize in concrete solutions that stand up to the Pacific Northwest climate. Here are some common concrete problems homeowners and businesses face in Hillsboro and how to fix them.

1. Cracking

Why It Happens: Cracks are one of the most common concrete issues, often caused by temperature changes, settling soil, or improper installation. In Hillsboro, frequent rain and occasional freezes can lead to expansion and contraction, putting stress on concrete surfaces.

How to Fix It:

• For small cracks, apply a concrete patch or sealant to prevent further damage.
• Larger cracks may require resurfacing or, in severe cases, professional repair to prevent structural issues.
• Proper joint placement during installation can help control cracking and extend the life of your concrete.

2. Spalling (Surface Flaking or Peeling)

Why It Happens: Spalling occurs when the top layer of concrete chips away due to moisture penetration, freeze-thaw cycles, or improper finishing techniques. This is common in Hillsboro, where rain can lead to water infiltration.

How to Fix It:

• Light spalling can be addressed with a concrete resurfacer to restore the surface.
• Severe cases may require grinding down the affected area and applying a new top layer.
• Sealing concrete regularly helps protect it from water damage and weathering.

3. Discoloration & Staining

Why It Happens: Concrete surfaces can become stained from oil spills, leaves, or exposure to deicing salts in winter. Oregon’s wet climate can also cause algae and moss growth, leading to unsightly green patches.

How to Fix It:

• Use a pressure washer or concrete cleaner to remove stains and organic growth.
• For stubborn stains, a mild acid wash or baking soda scrub can help lift discoloration.
• Sealing concrete can prevent future stains and make cleaning easier.

4. Settling and Uneven Concrete

Why It Happens: Over time, concrete may sink or become uneven due to soil erosion, poor compaction, or heavy loads. Hillsboro’s wet winters can cause soil movement, leading to uneven slabs.

How to Fix It:

• Minor unevenness can be corrected with self-leveling concrete overlays.
• For major settling, professional lifting techniques like slab jacking (injecting a stabilizing material beneath the slab) can restore the surface.
• Proper site preparation during installation can help prevent future settling.

5. Scaling (Surface Erosion)

Why It Happens: Scaling occurs when water penetrates the concrete surface, then freezes and expands, breaking apart the top layer. This is common in areas with freeze-thaw cycles, such as Hillsboro during colder months.

How to Fix It:

• Apply a resurfacing compound to restore the surface and improve durability.
• Avoid using deicing salts, which can worsen scaling issues.
• Seal concrete regularly to reduce moisture absorption.
