Foundation Solutions for Every PV Project

We understand that ground conditions and site constraints dictate the feasibility of solar installations. That’s why we provide cost-effective and easily assembled solar ground mounts with foundations suitable for any terrain. We utilise data from geotechnical, topographical, and other surveys to design a mounting system tailored to your site, ensuring optimal performance and longevity while eliminating unnecessary costs.

 

Our foundations are designed to be versatile, performing effectively across a range of terrains, including hard, soft, and rocky areas, as well as in locations where deep piles cannot be driven.

  • C-Pile

    Single Post
    Twin Post

    The most commonly used foundation, the C-Pile, is suitable for the majority of projects where a piling rig can be accessed. Designed for sites where the ground presents little or no restrictions, these piles are manufactured from structural-grade steel, ensuring a hassle-free installation and long-lasting durability.

    Suitable for:

    Sites where breaking ground is possible and geotechnical results permit use. Performs well in softer ground conditions

    Installation:

    Piling rig

    Material:

    S450 grade steel

    Coatings:

    ZM800, ZM1200 or Hot Dip Galvanised
    Corrosion protection is determined from ground investigations

    Dimensions:

    Determined by geotechnical and wind load test results. Embedment determined by geotechnical and pull-out test results

    Design Codes:

    Designed in accordance with BS EN 1991-1-4:2005 + A1:2010, BS EN 1090, BS EN 1991, BS EN 1993-1-1:2005, BS EN 1993-1-3:2006, BS EN 1993-1-8:2005, BS EN 1997-1:2004, BS EN 1997-2.

  • V-Pile

    Single Post
    Twin Post

    For sites that present rocky or firm ground, the V-Pile foundation excels in providing a robust solution. It is especially effective for areas that can be accessed by piling equipment but where the terrain poses challenges that typical equipment might not overcome. When ground investigation reports are provided, the V-Pile can be tailored with various lengths to match specific ground and wind conditions.

    The V-Pile foundation is compatible with our Single & Twin-Post Fixed Tilt System.

    Suitable for:

    Sites where breaking ground is possible and geotechnical results permit use. Performs well in rocky and/or hard ground conditions

    Installation:

    Piling Rig

    Material:

    S450 grade steel

    Dimensions:

    Determined by geotechnical and wind load test results. Embedment determined by geotechnical and pull-out test results

    Design Codes:

    Designed in accordance with BS EN 1991-1-4:2005 + A1:2010, BS EN 1090, BS EN 1991, BS EN 1993-1-1:2005, BS EN 1993-1-3:2006, BS EN 1993-1-8:2005, BS EN 1997-1:2004, BS EN 1997-2.

  • Gabion Basket

    Twin Post

    Gabion baskets are effective on sloped surfaces up to 10°, where embedment is not viable. Filled with heavyweight materials such as stones and rocks, the basket is anchored into place through gravity. Their flexibility allows them to adapt to uneven terrain, while the large ground contact area increases friction and prevents movement. Additionally, they control erosion by preventing soil loss and maintaining slope integrity over time.

    The Gabion Basket foundation is compatible with our Twin-Post Fixed Tilt system.

    Suitable for:

    Sites where breaking ground is not permitted (archaeological or geotechnical) and where local topography is not suited for ballasted foundations

    Installation:

    Steel plates inside of a mesh basket, with gabion stones as weight. Required gabion weights are calculated based on the system type and applied loads to counteract uplift forces.

    Material:

    Base Plate: S450 grade steel with ZM800 pre-galvanised coating
    Basket: Galfan Class A (Zn95%/AI5%) coated welded mesh gabions

    Dimensions:

    Gabion Basket aperture: 75 mm²
    Overall dimension determined by terrain, environmental conditions and system type

    Design Codes:

    Designed in accordance with BS EN 1991-1-4:2005 + A1:2010, BS EN 1090, BS EN 1991, BS EN 1993-1-1:2005, BS EN 1993-1-3:2006, BS EN 1993-1-8:2005, BS EN 1997-1:2004, BS EN 1997-2.

  • Ballasted

    Twin Post

    On flat sites where ground penetration is not feasible, whether due to underground utilities, archaeological importance, or extremely low cohesive resistance/high soil corrosivity, a ballast system offers an ideal alternative.

    Utilising readily available materials such as high-density concrete blocks and pre-cast concrete mono-blocks, the ballast system is not only straightforward to install but also exceptionally versatile in its application.

    Suitable for:

    Sites where breaking ground is not permitted (archaeological, ecological, geotechnical, landfill)

    Installation:

    Steel plates weighted with high density concrete blocks. Required ballast weights are calculated based on the system type and applied loads to counteract uplift forces.

    Material:

    S450 grade steel 

    Coatings:

    ZM800. Corrosion protection is determined from ground investigations.

    Dimensions:

    Plate size: 860mm x 985mm

    Design codes:

  • X-Anchor

    Twin Post

    With the use of only hand tools or an SDS drill, our patented X-Anchor foundation allows for solar installation on reclaimed ground, such as former landfills, shallow embedment, or when access to large machinery is limited.

    Suitable for:

    Sites that require shallow embedment and/or no heavy machinery

    Installation:

    Steel blade driven with a post knocker, SDS drill or hand tools

    Material

    X-Anchor Body: Hot rolled steel (S355JR) hot dipped galvanised to ISO 1461.
    X-Anchor Folded Blade: S450 grade steel with ZM800 or ZM1200 pre-galvanised coating.

    Dimensions

    Blade length determined by geotechnical and wind load test results

    Design codes:

    Designed in accordance with BS EN 1991-1-4:2005 + A1:2010, BS EN 1090, BS EN 1991, BS EN 1993-1-1:2005, BS EN 1993-1-3:2006, BS EN 1993-1-8:2005, BS EN 1997-1:2004, BS EN 1997-2.

  • Concreted Pile

    Single Post
    Twin Post

    For sites where ground penetration is feasible, and either a shorter pile is required or appropriate machinery is available, the piles can be concreted directly into the ground.
