From an urban planning perspective, hardscapes can include very large features, such as paved roads, driveways or fountains, and even small pools or ponds that do not exceed a certain safe height.
Hardscaping allows the erection of man-made landscaping features that would otherwise be impossible due to soil erosion, including some that compensate for large amounts of human traffic that would cause wear on bare earth or grass.
Lack of capacity, or poorly planned or executed drainage or grading of the surface can cause problems after severe storms or heavy extended periods of rain fall, such as flooding, washout, mud flows, sink holes, accelerated erosion, wet rot to wood elements, drowning of plants trees and shrubs, and even foundation problems to an adjacent home such as cracking the foundation, basement flooding due to water infiltration, and pest infiltration, such as ants and other insects entering through damaged areas.
These Structural Landscaping licenses include the erection and fabrication of decking, fences, carports, pergolas, paving and the construction of retaining walls.
Once the trades person has obtained their formal qualification they will be able to apply for a NSW contractors license which will enable them to carry out works over $5,000 including GST.
