Curbing is the detail that makes everything around it look deliberate. A driveway without a kerb spreads at the edges, a lawn without edging creeps into the paving, and a planting bed without a restraint loses its shape within a season.
A kerb only works if it cannot move. Each unit is bedded on concrete and haunched behind, so the load pushing against it is resisted by the mass of the haunching rather than by the kerb alone. This is the step most often skipped, and unhaunched kerbs tilt outward within a couple of years, taking the paving edge with them.
Straight runs are set to a string line and levelled unit by unit, because the eye picks up a deviation in a kerb line far more readily than in a wall. Curves are set out from a proper radius rather than eased by hand, and on tight radii we use shorter units so the curve reads smooth instead of faceted.
We supply half-batter kerbs where vehicles will ride against them, bullnose and square profiles for garden and path edging, and flush units where the intent is to separate materials without creating a trip line or interrupting the surface.
