What is kerb edging?

Kerb edging is a structural edge restraint that runs along the perimeter of paved areas to prevent lateral movement of the surface material. As paving settles or experiences traffic load, without a fixed edge the blocks or stone tend to shift sideways. A kerb holds the paving in place and maintains the intended design line.

Three main material types serve this function:

• Block kerbing uses concrete or clay blocks laid vertically or at an angle, common in driveways and patios across Cheltenham. These offer a finished appearance and can match or contrast with the main paving surface.
• Timber edging employs treated softwood or hardwood boards, typically 100-150mm deep, pressed into a sand or concrete base. It suits informal or contemporary designs and is softer underfoot if struck, though requires maintenance.
• Metal restraint comprises steel or aluminium channels, most often used in commercial settings or where a minimal profile is needed. Metal provides durability and a clean, modern line.

Installers set kerbing on a concrete haunching or mortar bed to lock it in place and provide stability beneath ground level. The depth and type chosen depends on anticipated loads (a residential driveway differs from a high-traffic car park) and aesthetic preference. Proper kerb installation is essential to drainage performance and long-term paving integrity. Local paving contractors in Cheltenham select kerb types based on soil conditions, budget, and design intent.
