Concrete Curbing vs Plastic Edging in Myrtle Beach — Which Wins?

If you've replaced plastic landscape edging even once in your Myrtle Beach yard, you already know the frustration — sections pop above grade, gaps appear, grass crosses over, and within 2–3 years you're back at the hardware store buying more. Concrete landscaping curbing eliminates this entirely. Here's the complete comparison.

Plastic Edging in Myrtle Beach

How it performs: Plastic landscape edging is the most common choice for initial installations because it's the cheapest upfront option. In Myrtle Beach's subtropical climate, it performs poorly for several reasons:

• Thermal expansion and contraction from South Carolina's temperature swings causes plastic to heave, bow, and buckle over one to two seasons
• UV degradation from intense sun exposure makes plastic brittle and prone to cracking within 2–4 years
• Shallow installation depth (typically 4 inches) means plant root growth and soil movement regularly displaces sections above grade
• Myrtle Beach's heavy rainfall creates soil movement that plastic can't withstand

Typical lifespan: 2–4 years before visible failure requiring replacement

Cost over 10 years: $150–$300 in materials + 2–3 reinstallation labor costs = $400–$800+ for ongoing plastic edging maintenance

Metal Edging in Myrtle Beach

Metal edging (typically aluminum or steel) performs better than plastic for large-leaf debris management but has specific problems in Myrtle Beach's salt-air environment:

• Standard steel edging corrodes noticeably within 3–5 years in coastal conditions — rust staining on adjacent concrete is common
• Aluminum performs better on corrosion but still heaves and shifts from soil movement
• Neither material prevents the grass encroachment that creates ongoing re-edging labor

Typical lifespan: 5–8 years depending on material and exposure

Concrete Landscaping Curbing

Concrete curbing is poured in place as a continuous, monolithic border — it doesn't have joints that separate, doesn't shift from soil movement, and isn't affected by the thermal cycling, UV, or corrosion issues that defeat other edging materials.

• Thermal stability: Concrete expands and contracts minimally and handles Myrtle Beach's temperature range without movement
• Salt air resistance: Concrete is unaffected by salt air unlike metal products
• UV resistance: No degradation from UV exposure
• Depth and stability: Properly installed concrete curbing is anchored at a depth that resists both soil movement and grass root encroachment
• Mulch retention: The raised profile retains mulch during Myrtle Beach's heavy rainfall events — a significant practical benefit

Typical lifespan: 15–30+ years

Cost: $4–$7 per linear foot installed. A typical front yard installation (60 linear feet): $240–$420.

The Math

Plastic edging over 10 years: $400–$800 (materials + labor to reinstall 2–3 times) plus ongoing re-edging labor at every mowing visit.
Concrete curbing: $240–$420 installed once, no ongoing edging labor required, lasting 15–30 years.

Concrete curbing pays for itself versus ongoing plastic replacement within 3–5 years for most Myrtle Beach properties.
