Underground infrastructure is a critical phase of complete landscape construction, providing the systems that support proper drainage, utilities, and long-term site performance. This work is completed early in the construction process to ensure surface features, structures, and planting are built on a stable and well-prepared foundation.
Construction Sequence:
Design & Planning
Site analysis and planning identify drainage requirements, utility routes, and elevation considerations before underground work begins.
Underground Infrastructure
Drainage systems, plumbing lines, electrical conduits, and sleeves are installed early to establish proper water management, power access, and long-term site functionality.
Structural Preparation
Trenching is backfilled, compacted, and stabilized to support structural elements and prevent future settling or movement.
Hardscape & Masonry
Permanent surfaces and structural features are constructed over properly prepared subsurface systems to ensure durability and alignment.
Irrigation & Calibration
Irrigation components are installed and tested to integrate with existing drainage and utility systems.
Softscape & Finishing
Soil preparation, planting, and final grading complete the landscape while protecting underground systems.
Underground infrastructure forms the unseen framework that supports every surface element in a landscape construction project. Proper installation of drainage, plumbing, and electrical systems ensures water is managed correctly, utilities are protected, and the site performs reliably over time.
Completing this work early in the construction process allows structural and surface features to be built without disruption. Careful trenching, compaction, and coordination prevent future settlement issues and reduce the risk of damage once hardscape and planting are installed.
When underground systems are planned and installed correctly, they create a stable base for all subsequent construction phases. This approach protects long-term performance, simplifies maintenance, and supports a cohesive, well-functioning outdoor environment.
Effective drainage is essential to long-term landscape performance. Underground drainage systems manage surface water, control runoff, and protect structural elements from erosion or water damage. Proper grading, drain placement, and water flow planning help prevent pooling, soil displacement, and pressure buildup beneath hardscape surfaces.
By addressing drainage early in the construction process, the site is prepared to handle seasonal changes and long-term environmental conditions without compromising surface features or plant health.
Plumbing and electrical infrastructure provide the foundation for functional outdoor environments. Underground lines support irrigation systems, lighting, water features, and other landscape elements that require reliable utility access.
Installing these systems before surface construction begins allows utilities to be protected, routed efficiently, and integrated seamlessly into the overall landscape layout.
Proper subsurface preparation ensures the stability of all construction elements above. Trenching, backfilling, and compaction are carefully coordinated to prevent future settling, shifting, or damage to surface installations.
This preparation phase supports long-term durability by creating a stable base for hardscape, structures, and planting while protecting installed underground systems.
