"We cannot say enough positive things about our experience with Black Diamond Paver Stones & Landscape, Inc., our project manager Nick Miller, our foreman Raymundo and his wonderful hardworking crew/sons. It was very refreshing and relieving to find a company and individuals that we not only trust but do remarkable work. My wife and I were budgeting for a project to replace our back lawn (or what was left of it) with synthetic turf so that our young kids had a safe and clean play area. We received several quotes from other companies but ultimately chose Black Diamond because of Nick. From the first day we met Nick and throughout the entire project, Nick was easy to reach, professional, knowledgeable, and understanding when our toddlers were competing for attention (i.e., having meltdowns). At no point did Nick make us feel pressured or like we were being difficult (even when we probably were). He simply answered our questions, gave us recommendations, and ultimately let us choose what worked best for our needs. Raymundo and his team quickly began work after coming to an agreement on the scope of the project. Our project began relatively small but evolved once we saw the amazing quality of Raymundo’s work and included an expansion of our back lawn, mow strips (front and back), replacement of our front walkway, added steps with lights, and paver overlay of our front porch. The quality of Raymundo’s work is unparalleled to any other company we have worked with in the past. Aside from their knowledge and quality of their work, Nick and Raymundo both stand out from others because of their honesty and flexibility. They both went above and beyond our expectations and kept us involved and informed throughout the project. There were a few times during the project that they let me know of minor changes or issues. These were often so minor that I would not have even known or noticed but they were transparent, which allowed us to have a conversation and come to an agreement on next steps. There were many more times where we came to them with questions or changes and they were equally willing to have a conversation and accommodate us whenever possible. My wife and I could not be happier with the outcome of the work with Black Diamond, Nick, and Raymundo. We have already referred them to several family members and friends and will certainly be using them again for future projects."

The depth of decomposed granite depends on the load the surface will support. For a vehicle driveway, install decomposed granite six inches deep. For pedestrian areas, use three inches, and for decorative surfaces, one inch will suffice. Heavier loads require thicker layers to ensure stability, drainage, and longevity, while lighter uses can maintain their appearance with less material.
One cubic yard of decomposed granite covers 54 square feet when laid to a six-inch depth. This conversion is derived by dividing the volume in cubic feet by the depth in feet. The calculation is fundamental for project planning because it converts three-dimensional volume into the two-dimensional area of coverage. Due to potential settling and compaction after installation, pros recommend an extra 15% to ensure the installed layer meets precise design requirements and maintains robust stability over time.
Determining whether a base layer is necessary for decomposed granite installation requires careful assessment of your project needs. A base layer of crushed rock or gravel provides essential support, improved drainage, and enhanced stability. Utilizing a solid base improves the overall structure by absorbing weight, reducing erosion, and extending the life of the surface. Additionally, a properly compacted base layer minimizes shifting and settling, ensuring that the decomposed granite remains evenly distributed and effective over time.
