The Ideal Choice for Non-Invasive Installations

What is a ballasted foundation?

Having a solution that requires no breaking ground is essential. Whether there's an area of archeological interest, underground services, impenetrable ground makeup, land with very low cohesive resistivity or high corrosivity - the Solarport ballast system is always available to provide the solution.


By applying specified weight to the steel plate, the ground-ground mounted solar array will achieve and surpass sufficient results in high winds, without penetrating the ground.

Using readily available materials including the use of high-density concrete blocks, reclaimed concrete railway sleepers and pre-cast concrete mono-block, the ballast system is easy to install and extremely diverse in its applications.
