Root Anchor Foundation

Foundation Solution

A project-specific solar foundation solution for sites where conventional pile penetration is restricted, including landfill and other sensitive ground conditions.

Overview

Root anchor foundations provide a practical alternative for ground-mounted solar PV systems where conventional driven pile installation is restricted or only shallow ground penetration is permitted.

At HTR Solar, our root anchor foundation solutions are engineered around the project-specific mounting system, structural requirements, ground conditions and permitted installation depth. They are particularly suited to landfill and other sensitive sites where deeper pile installation may not be appropriate.

Anchor arrangement, length, inclination, embedment and connection details are defined through project-specific structural design and drawings. Where required, testing can be incorporated to verify foundation performance against the project design requirements.

Our root anchor foundations integrate directly with HTR Solar mounting systems, providing a coordinated connection between the foundation and above-ground solar mounting structure.

Why Choose Our Root Anchor Foundations?

  • Project-Specific Engineering

    Our root anchor foundations are engineered around each project's structural requirements, ground conditions, permitted penetration and mounting system configuration.

  • Restricted Ground Penetration

    A practical foundation solution where conventional pile driving is restricted or only shallow ground penetration is permitted by site conditions.

  • Suitable for Landfill Sites

    Root anchors can provide an effective solution for landfill and other sensitive sites where deeper ground penetration may be restricted.

  • Adaptable Anchor Arrangement

    Anchor length, diameter, inclination, embedment and arrangement can be developed around project-specific foundation and installation requirements.

  • Integrated with HTR Solar Systems

    Root anchor foundations integrate with HTR Solar mounting systems, providing a coordinated foundation-to-frame connection for the complete structure

  • Testing & Verification

    Where required, project-specific testing and verification can be incorporated to confirm foundation performance against the project design requirements.

Site Conditions & Root Anchor Foundation Design

Every solar site presents different ground conditions and structural requirements, so our root anchor foundation solutions are developed around the needs of each project. Anchor arrangement, geometry, inclination and embedment requirements are coordinated with the solar mounting system design, providing an integrated approach between the foundation and above-ground structure. Where required, project-specific pull-out testing or verification can be incorporated to support the foundation design and confirm performance requirements.

Root Anchor Installation & Site Support

Accurate installation is essential to the performance and efficient assembly of the complete solar mounting structure. HTR Solar defines the required upright position, anchor collar arrangement, anchor orientation and installation requirements through the project-specific drawings. Root anchor bars are installed at the specified inclination and orientation before the completed foundation arrangement is checked for security, upright height, plumb and orientation.
