Granolithic screed, also known as granolithic paving and granolithic concrete, is a type of construction material composed of cement and fine aggregate such as granite or other hard-wearing rock. It is generally used as flooring, or as paving. It has a similar appearance to concrete, and is used to provide a durable surface where texture and appearance are usually not important. It is commonly laid as a screed. Screeds are a type of flooring laid on top of the structural element to provide a level surface on which the "wearing flooring" is laid. A screed can also be laid bare, as it provides a long-lasting surface.
