Concrete curb
profiles & sizes.
Four profiles, drawn to scale. The right one depends on what the curb has to hold back — pine straw, river rock, Bermuda runners or a gravel driveway.

Which profile
fits your yard?

All four are six inches wide and extruded as one continuous piece with steel cable run through it. What changes is the height and the shape of the face.

Cross-sections

Each profile,
drawn to scale.

Drawn at the published sizes. The 1/8″ steel cable shown in section runs the full length of every profile to stop shifting and separation from settling or erosion.

6×4 Slant curb

The industry standard for residential landscape edging — the balance point between how it looks and what it has to hold back.

  • Easier mowing. The sloped face lets a mower wheel ride the edge, so you trim along the curb instead of around it.
  • Lower maintenance. Less routine edging and string trimming every week of the growing season.
  • Perfect containment. The high back keeps mulch, stone and soil off your walkways.
  • Custom styling. Takes the full range of stamped patterns and integral colors.

Best for — Flower beds and garden borders · Walkway and pathway edging · Tree rings

6×5×3 Super Slant curb profile, cross-section1/8″ STEEL CABLE5″3″6″

6×5×3 Super Slant curb

Six inches wide with a 5″ back and a 3″ front lip. A bolder line and a stronger barrier than standard residential edging.

  • Maximum material retention. The 5″ back wall holds heavy decorative rock and deep mulch without spill-over.
  • Thick turf barrier. The raised 3″ front lip blocks aggressive runners like Bermuda and St. Augustine.
  • A wider canvas. The broad angled face shows off stamped patterns and secondary color better than any other profile.
  • Commercial-grade strength. A full 6″ concrete footprint that takes heavy mowing equipment without shifting.

Best for — Premium beds and custom tree rings · Lawns with thick, high-growing sod lines · HOA common areas and light commercial

6×4 Square curb profile, cross-section1/8″ STEEL CABLE4″6″

6×4 Square curb

Clean lines and a bold geometric presence. The contemporary answer, and the one that stops gravel migrating out of a driveway.

  • Gravel driveways. Locks stone aggregate inside the driveway perimeter instead of across your lawn.
  • Commercial parking lots. Clear zoning and a durable perimeter edge for storefronts and commercial lots.
  • Modern flower beds. Frames rock, soil or mulch cleanly against contemporary architecture.
  • Walkways and pathways. A distinct raised border that guides foot traffic and protects the plantings beside it.

Best for — Gravel driveways · Commercial parking lots · Modern flower beds · Walkways

6×6 Block curb profile, cross-section1/8″ STEEL CABLE6″6″

6×6 Block curb

The high-performance end of the range. Six by six, for commercial sites and residential landscapes that take real abuse.

  • High load capacity. Built to survive delivery trucks, trailers and commercial mowers riding the edge.
  • Maximum stability. The largest cross-section we pour, with the steel cable running through all of it.
  • Custom textures. Still takes stamped patterns — strength does not cost you the finish.
  • Seamless integration. Poured continuous into the same run as your lighter profiles where a site needs both.

Best for — Commercial perimeters · Heavy-traffic edges · Retaining bed lines · Storefronts

Applications

Where each
one usually goes.

The profile we usually recommend for common jobs. Every yard is different, so we confirm it with you on site.

Slant or Super Slant

Tree rings

Circles the tree to protect the trunk from mower damage and hold protective mulch in place.

Slant

Flower beds and borders

Clean lines that keep decorative aggregate, mulch and soil where you put them.

Square

Gravel driveways

Locks stone aggregate inside the driveway perimeter instead of letting it scatter across the lawn.

Super Slant

HOA common areas

A bolder line and a stronger barrier for shared beds, entrances and walkways.

Square or Block

Commercial lots and storefronts

Clear, durable perimeter edges that define zones and stand up to traffic.

Slant or Square

Walkways and pathways

A polished transition between lawn and walkway that guides foot traffic and protects plantings.

Common to all four

Extruded,
not assembled.

Every profile leaves the curb machine as one continuous piece. That eliminates the shifting you get with modular edging, keeps weeds from growing through gaps, and stops sod growing underneath when the base is prepared correctly.

  • 1/8″ steel cable run through the full length of the curb.
  • Control joints cut roughly every 12 to 24 inches to relieve stress as it cures.
  • Any pattern and any color on any profile.
  • 1-year warranty against defects in materials and workmanship.
