Sealing Interlock Stone Driveway

Why should stone and concrete pavers be cleaned and sealed?
Stone and Concrete is commonly used in the construction of Pool Decks, Patios, Walkways, Driveways, Garage & Basement Floors, Brick, Block and Mortar. Concrete paving materials are offered in the form of Exposed Aggregate, Patterned Concrete, Paving Stones (commonly referred to as interlocking stones) Slab or Pre-Cast. Concrete can be natural or colored with pigments and is found just about everywhere you look.
The appearance and/or integrity of concrete can be effected by the following:
Staining caused by the absorption of Engine Oils, Transmission and Brake fluids, Automotive and Barbecue Grease, Rust, Paint, Rubber, Red Wines or Colas, Tree Berries or Sap, Bird Droppings and Animal Urine. Stains are aesthetically unattractive and may be difficult to remove unless the stone or concrete is previously protected.
