How To Lay Cobbles Light use> for paths, patios and landscape features. For light use cobble projects, a bedding layer will suffice. Step one> Remove layer of top soil to a depth of 50-70mm for the complete area that cobbles will be installed. Prepare the mortar mix of sand and concrete to a ratio of 4>1. The bedding layer of the mortar mix must be at least half the average depth of the cobble. Ensure the mortar is semi-dry so cobbles can be bed into it easily. Only spread the mix one square metre at a time, as the concrete may harden. Maintain a level throughout this process to create a flat surface. Step two> When placing the cobbles into your preferred style always place the stones as tight as possible. For uniformity keep the same placing width throughout. Lay the cobbles with the flattest surface uppermost as to present a level surface as possible. Step three> After placing the stones in the one square metre into the bedding place a flat wooden surface over the stone and tap the wooden surface with a rubber mallet to fix the cobbles into the bedding securely and level. Continue this step until the area is covered. Step four> Pointing stage. Depending on the finish desired pointing can vary. A good practice is to by hand brush a semi-dry mortar mix into the jointing to leave approximately 25mm of the cobble stones left upstanding. Step five> The mortar should set within 2 hours, sometimes faster in summer and conversely slower in winter. Keep protected from traffic for 48 hours. Heavy use> driveways, forecourts For heavy use/traffic cobble projects it is required to have a sub-base layer, a base layer and a bedding layer. Step one> Excavate the entire area to be cobbled to the required depth for all levels. Usually 250-400mm in depth. Step two> There are two types of materials suitable for sub-bases. Unbound> stone aggregates. Bound> Concrete. Fill the total area with your chosen material to 100-150mm of depth for the total area. A sub base layer should be laid as a separate layer. This is needed to ensure the layers above have enough strength to carry considerable weight. Keep the level consistent across the area to a difference of no more than 10mm. Allow 24 hours for layer to dry before proceeding. Step three> Base layer is usually a concrete layer of approximately 75mm across the entire area. Step four> Bedding layer. Prepare the mortar mix of sand and concrete to a ratio of 4>1. The bedding layer of the mortar mix must be at least half the average depth of the cobble. Ensure the mortar is semi-dry so cobbles can be bed into it easily. Only spread the mix one square metre at a time as the concrete may harden.
