I am asked this question a lot and usually away from earshot of others for fear that they may be asking what everyone else already knows. That is not the case because the person beside you probably asked me the same question when you were not in earshot. Here is some light reading from the definition to features.
“Hardscape” consists of the hard elements of landscaping replacing the natural earth, masonry, wood, concrete and natural stone.
Residential and commercial green space examples are patios, gazebos, decks, fences, retaining walls, water features, sidewalks and driveways.
Hardscaping can be done by homeowners although the largest problem we encounter is the lack of knowledge with slope for water drainage. Sometimes it is necessary to install big o, drainage fabric, and clear aggregate and commonly is used for retaining walls. With the precision of a skilled contractor most people cannot see the slope for water drainage.
