Paving is Labor Intensive
The ground surface below the pavers requires precision preparation to an exact depth. Various aggregates from gravel to sand need to be placed and compacted to provide a stable surface area with adequate drainage for paver installation. Even for a small patio or short walkway, this requires removal of a large amount of dirt. A driveway of pavers requires removing soil measured in tons. The displaced soil is replaced with gravel and sand. Professionals use powered equipment to prepare the surface evenly. Also, displaced dirt needs to be hauled away.
Installation of a small paved area outside of an entrance door may be a weekend project for a do-it-yourself homeowner. However, most paving projects homeowners envision are long sidewalks, garage driveways, pool areas and backyard patios. This requires ordering gravel and sand measured in cubic yards along with ordering an accurate amount of bricks required to complete the job without falling short or having too many left over. An error in calculating material needs will have homeowners running out and having to pay extra delivery fees or having to dispose of a significant amount of leftover aggregate or bricks upon project completion.
Practice is what makes for precision patterns in masonry work. Do-it-yourself paving jobs require learning as the work progresses. Errors in laying out paving bricks evenly is readily apparent in the finished project. Measurement errors result in the need to cut bricks into smaller pieces. Cut bricks have less ground stability, especially at the edges. Professionals measure to avoid cutting bricks on a project as much as possible.
Grading the Surface
Runoff from rain is a major concern for larger paved areas. A rainstorm will cause hundreds if not thousands of gallons of runoff. All of that water needs to go somewhere. Professionals will grade the surface area to prevent runoff from going toward the structure. Amateur installations can result in wet garages and homes if proper surface grading is not completed. Larger paved areas require installation of drainage systems to carry away runoff.
Longevity of a surface areas where brick pavers are installed requires more thought and preparation going into the layers and systems beneath the actual bricks than to the layout of the bricks themselves. Professionals have the tools and expertise to prepare the surface area where brick pavers are going to be installed. Homeowners in a rush to complete a weekend project may cut corners or miss a crucial step due to lack of training or experience. This results in displacement of bricks that become trip-and-fall safety hazards. For the best brick paving job, hire experienced professionals.
