Permeable Paving is an eco-friendly paving method that allows water to pass through the surface into the ground below, instead of running off like with traditional paving. It's becoming increasingly popular in landscaping and construction projects because it helps manage rainwater naturally and reduces flooding risks. This type of paving can include special concrete, porous asphalt, or interlocking pavers with gaps for water drainage. It's similar to traditional paving but serves the additional purpose of water management. You might also hear it called "pervious paving," "porous paving," or "sustainable drainage systems (SuDS)."
