1 Yard of Limestone 40 mm Limestone is a fundamental stone in varying sizes, perfect for increasing the aesthetic landscape appeal of any garden. Initially, the rock will be of a white hue due to the limestone dust generated by the tumbling of the rock but will fade into a darker shade over time or after washing. This Limestone 40 mm is a mid-sized variation you can purchase. Other than the size difference, the appearance throughout all the sizes will generally be the same. The "medium" sized Limestone functions best as an aesthetic booster for any landscape or yard. Drawing from our experiences, we normally install our Limestone products with a thicker fabric (~5 oz). By installing a thicker fabric, it will assist with the following: Separation of topsoil or base material for easy cleaning. Defence against, not the elimination of weeds. The removal of weeds will be easier as the roots of grown weeds will not be able to take heavy root into the soil with the fabric being present. The medium limestone has a larger surface area to volume ratio than the "large" limestone, but less so than the "small" limestone. This ratio will assist with the defence against weeds as opposed to the "large" limestone. Delivery Only Delivery Details: All products sold online have a delivery charge.
