Frequently Asked Questions

  • How does GPS-guided grading improve site preparation?

    GPS-guided grading uses satellite technology to ensure precise elevation and slope calculations, which improves drainage accuracy and foundation stability. This method reduces errors and rework compared to traditional grading techniques. At Cornerstone Grading and Development, we use GPS guidance to meet local building codes and prevent future drainage issues.
  • What's included in professional pond installation?

    Professional pond installation includes site analysis to assess soil and drainage, excavation to proper depth, installation of professional-grade liners, and integrated filtration systems. Native plant selection is also included to create balanced aquatic ecosystems. At Cornerstone Grading and Development, we design ponds that sustain healthy water quality year-round.
  • When should you schedule land clearing for storm damage?

    Storm damage clearing should be scheduled as soon as it's safe to assess the property, ideally within days of the event to prevent further hazards or decay. Prompt removal of downed trees and debris also protects structures and allows for faster site restoration. We provide eco-friendly disposal and stump removal as part of cleanup.
  • What affects the cost of site grading services?

    Site grading costs depend on lot size, existing slope conditions, soil type, and the amount of earthwork required for proper drainage. Additional factors include access for heavy equipment and compliance with local codes. At Cornerstone Grading and Development, we evaluate these elements during site analysis to provide accurate project scope.
  • What's the difference between selective clearing and full removal?

    Selective clearing removes only specific trees or brush to preserve desirable vegetation and maintain natural aesthetics, while full removal clears all vegetation from a site. Selective clearing is ideal for building sites that benefit from shade or erosion control. We assess each property to recommend the best approach for your project goals.
  • How does stump grinding restore landscaping areas?

    Stump grinding uses commercial-grade equipment to pulverize stumps and root systems below ground level, eliminating tripping hazards and freeing space for replanting. The grinding process converts waste into mulch that can be used for soil enrichment. This method allows grass, plants, or hardscaping to be installed immediately after grinding.
  • Why is erosion control important during site grading?

    Erosion control prevents soil loss, protects water quality, and maintains slope stability during and after grading. Without proper erosion management, rain can wash away topsoil and create drainage issues. At Cornerstone Grading and Development, we implement erosion control measures that comply with Duncan, SC regulations and safeguard your investment.
  • Can site grading prevent basement flooding in South Carolina?

    Yes, proper site grading directs water away from foundations and prevents pooling near basements, which is critical in areas with heavy rainfall like South Carolina. Grading creates positive drainage slopes and integrates with stormwater management systems. We design grading plans that address local soil conditions and seasonal weather patterns in Duncan and surrounding areas.
  • What drainage solutions work best for residential properties?

    Effective residential drainage solutions include French drains, swales, catch basins, and proper grading to channel water away from structures. The best system depends on soil type, lot slope, and rainfall patterns. At Cornerstone Grading and Development, we design stormwater management systems tailored to prevent flooding and erosion on your property.
  • How do you prepare a site for utility installations?

    Utility corridor preparation involves clearing vegetation, grading access routes, and coordinating with utility services to ensure safe excavation and installation. Proper preparation prevents delays and protects existing infrastructure. We handle all site work needed for efficient utility development while maintaining compliance with local regulations.
  • What's the biggest mistake people make with pond liners?

    The biggest mistake is choosing low-quality or undersized liners that lead to leaks, punctures, and costly repairs. Professional-grade liners are thicker, UV-resistant, and properly fitted to prevent water loss. At Cornerstone Grading and Development, we use durable liners designed for long-term aquatic ecosystem health and structural integrity.
