What Maintenance Should I Consider?
High-volume pedestrian areas are proactively inspected at least once every 2 years. Neighborhood sidewalks are proactively inspected at least once every 10 years in most cities.
Keep in mind that even naturally occurring cracks can be an issue if not filled with a suitable caulk. When cracks fill with water and then freeze, the expansion of the water causes additional damage to cement. It is far cheaper to fill cracks than replace crumbling concrete.
Recommendations on sidewalk sealers?
Film-forming sealers are the type most often used for decorative concrete work, and they do just what the name implies-form a protective film on the surface of the concrete that will prevent the intrusion of water, chlorides, and harmful deicing chemicals. Most of them also impart a sheen that highlights the beauty of colored or exposed aggregate finishes. Because good traction is important on walkway surfaces, a slip-resistant additive can be mixed into the sealer before application to improve traction.
Are there Oregon laws on sidewalk maintenance?
"The owner(s) of land abutting any street in the City shall be responsible for constructing, reconstructing, maintaining and repairing the sidewalks, curbs, driveways and parking strips abutting or immediately adjacent to said land."
You can't choose to ignore the maintenance on your home. Poorly maintained walkways can result in litigation by anyone who is injured on your property.
