Project overview

Concrete problems often have underlying causes, not just cosmetic ones. On this project in Blue Grass, Iowa, we repaired a deteriorated front stoop, replaced damaged concrete steps and sidewalk sections, and installed a new underground downspout extension to help move roof water away from the home.

Managing roof runoff is one of the best ways to protect concrete from premature deterioration. Directing water away helps reduce soil erosion, settling, freeze-thaw damage, and unnecessary stress on sidewalks and entryways. We also repaired the peeling face of the existing stoop using professional-grade concrete repair materials designed for long-term durability.

At Behncke Construction, we focus on repairing the cause of the problem—not just the concrete you can see—so homeowners get repairs that last.

Project details

The visible problem was failing concrete, but the underlying cause was water. Along with replacing the damaged steps and sidewalk sections and resurfacing the peeling stoop face with professional-grade repair material, a new underground downspout extension was installed to carry roof runoff away from the concrete and the foundation.

What homeowners should know

Most outdoor concrete failure comes down to water and freeze-thaw. When roof runoff and surface water collect around steps, sidewalks, and stoops, the soil beneath erodes and settles, and water that soaks into the concrete expands as it freezes — spalling the surface and cracking slabs.

That’s why lasting concrete repair starts with drainage. Moving roof water away with downspout extensions, and setting new flatwork on a properly prepared, well-drained base, protects the repair from the same cycle that broke the original concrete. Surface repairs use bonding materials made for exterior freeze-thaw exposure.
