When to Replace Your Concrete Walkways?

Lifespan of concrete walkways

In typical conditions, a well-maintained and sealed concrete walkway should last between 20-30 years in Fredericton, NB. Several factors impact the longevity, including how the sidewalk is constructed, the quality of materials used, and ongoing maintenance practices.

Sealing your walkway regularly, repairing any cracks promptly, and limiting the use of de-icing salts in the winter can extend its useful life. Regular preventative maintenance like snow removal helps prevent damage from freeze-thaw cycles that cause cracking over time. Know that the lifespan can be shorter if any of these best practices are neglected.

Warning signs – time to replace concrete walkway

Extensive cracking

Pervasive and large cracks spanning much of the walkway indicate the concrete is cracked beyond the point of repair. Especially if cracks are deep, uneven, or intersecting, the structural integrity has likely been compromised. At this stage, the only viable option is full replacement to avoid potential safety hazards from crumbling or collapsing sections.

Widespread spalling

If spalling affects more than just isolated spots, choosing replacement is necessary before the problem progresses further. Waiting risks uneven sinking creating trip risks or permitting water ingress into cracks beneath detached pieces. Replacement renews the flat, solid surface required for safe pedestrian traffic.

Severe unevenness

Major unevenness across large areas signals settling has undermined the existing concrete to an unsafe degree requiring replacement. A wavy, unstable surface can easily contribute to trips or falls. Grinding down high spots would not create a reliably even surface with proper drainage. Only total reconstruction ensures long-term grade and strength.

Drainage/Pooling issues

When water stands after rain instead of draining smoothly, overhaul is needed if re-grading alone fails to solve the problem. Stubborn pooling indicates sub-grade instability from saturation, pointing to replacement of the base material and full resloping for complete resolution.

Advanced erosion

Where edges have collapsed or worn away significantly, replacement is the only solution before deteriorating internally as well. Patching severely eroded walks risks compromising remaining integrity over the lifespan. Reinstatement with a new concrete walkway provides the most durable long-term solution.

Major root damage

Tree roots that have buckled or cracked a walkway in multiple areas have likely degraded its structural properties throughout. It is time to replace the entire concrete to avoid potential liability from failure.

Why you Should not Neglect Sidewalk Maintenance

• Safety hazards increase: Overly cracked or uneven surfaces create tripping hazards. Deteriorating sections could crumble underfoot unexpectedly.
• Further damage occurs: Neglecting cracks allows water access to concrete’s pores. Frozen water causes additional cracks as temperatures fluctuate. Numerous small cracks connecting accelerates crumbling sections.
• Costs rise over time: Postponing maintenance results in bigger issues down the line. Replacement is far more costly than occasional sealing/patching.

By promptly addressing signs of deterioration, homeowners can avoid these serious issues and protect both residents and their property’s value for many years.

Professional assessment

If multiple warning signs are present or a single issue seems especially problematic, it’s time to bring in an expert. A qualified concrete contractor can inspect walkways and determine the level of any underlying damage or whether superficial cracks have compromised structural integrity. They know to examine beyond obvious cosmetic issues. Deep cracks, weakening material below problem areas, and improper drainage requiring full replacement can be hard for a layperson to diagnose.

It’s important to understand professional recommendations. While some may advise concrete repair options for isolated issues, extensive signs may mean replacement is necessary for safety and to avoid costly repairs in future.

You may follow-up questions to comprehend advice and ensure the right solution for your situation. Rely on a contractor’s experienced expertise rather than attempting your own assessment since lives depend on concrete that won’t crumble underfoot. Their guidance provides a correct decision on whether repairing or fully replacing sections of walkway is the suitable option.

Repair or Replace – Making right decision

In the following circumstances repair is sufficient for concrete walkway:

• Hairline surface cracks can often be sealed to prevent worsening.
• Small sections of detached concrete may be cut out and patched.
• Grinding can level minor sunk or raised areas within tolerance.
• Minor low spots could potentially be filled rather than full digging out.
• Re-grading runoff paths may suffice for poor drainage in some cases.
• Patching and tapering could work for contained edge crumbling.

Always get a professional assessment first but minor issues caught early may sometimes be addressed through less invasive repairs.

FAQ about concrete walkways replacement

Is it better to resurface or replace concrete?

For minor surface damage like hairline cracks or rough patches, concrete resurfacing involves grinding down the top layer and reapplying a concrete sealant or overlay which is usually sufficient and more affordable than full removal and replacement. Extensive cracking, settling or base issues typically require complete replacement of the slab for long-term stability.

How often should I call professional for concrete sidewalk maintenance?

In areas prone to freeze-thaw cycles from frequent snowfall and use of salt, yearly inspections allow early detection and prevention of deterioration. For areas with normal conditions, homeowners can often get by with inspection and sealing every 3 years with preventative maintenance in between as needed. Catching issues promptly extends the concrete’s service life.

Can we replace a concrete walkway with pavers?

Yes, as an alternative to poured concrete, many homeowners choose to replace deteriorating slabs with interlocking pavers which are equally durable but allow for adjustment if settling occurs. Atlantic Brick and Stone have experience installing many styles of brick, stone or concrete pavers that create an attractive, low-maintenance walking surface.
