It is widely recommended to bed your edgings into a concrete foundation that is at least 100mm thick. Ensure that roughly half the depth of the edging stone is haunched with concrete on the outside face to provide adequate lateral support and prevent movement.
Essential Edgings, Kerbs and Step Risers for Hard Landscaping
When planning your layout, these edging stones work seamlessly alongside natural Paving Flags to provide a solid, professional finish. Securing your kerbs with a sturdy mortar or haunching mix, typically combining Building Sand and Cement , guarantees they will not shift under pressure. For garden borders, installing a raised kerb of at least 150mm helps to neatly contain Decorative Aggregates or soil, keeping your pathways clear and reducing long-term maintenance.
Most of our edgings and risers are manufactured from robust concrete or natural stone, offering excellent frost resistance and load-bearing capabilities. For heavy-duty boundary applications, specific profiles like our solid Road Kerbs comply with stringent load and dimensional requirements, ensuring reliable longevity in harsh weather. You will find them straightforward to handle and install, with versatile shapes that adapt easily to both straight runs and sweeping 90-degree curves.
Kerbs, Edgings & Risers FAQ's
Yes, standard kerbs can be used to lay curves and arcs. For very tight curves, you may need to use specialised radius units or carefully cut standard lengths down using a power saw to prevent unacceptably wide mortar joints between the stones.
A standard haunching mix typically consists of three parts sharp sand, six parts gravel, and one part cement. This mixture should be mixed with water until it is damp but stiff enough to hold its shape, ensuring the kerbs do not sink out of level during installation.
Our concrete and stone edgings meet standard dimensional and load-bearing requirements. This ensures they possess the necessary frost resistance and structural strength for domestic driveways and pedestrian footpaths.
You will need a spade for excavation, a taut string line and line pins to ensure accurate alignment, a spirit level for checking gradients, and a rubber mallet to gently tap the heavy stones into their final position without causing damage to the surface.
