Ramming Piles

Speaking of areas, which have clay or gravel, the ground is known to have a good soil cohesiveness. It’s the same case when it’s up to dense sand or low water tables. Those kind of projects are usually large-scaled. Some of the advantages here are the speed of the installation, the lack ot cure time and of course – the low performance costs. Not that suitable for smaller projects.

Pre-drilling Piles

These are the best to perfectly math areas, where soil cohesion is poor, since they are the easy to be installed via auger attachments or other rotating into the ground equipment. Once placed, they basically lock the structure into the soil. Considered also time and money saving, they have less environmental impact because of the less pollution method during installation. Of course, it’s recommended to make pull tests before.


These are actually the pre=drilling holes into the ground, made before screwing excavators. Of course, they might be installed also directly into the ground if no refusal issues. Earth-screws are considered to have a higher cost when compared to other type fondations, since there’s a separate machine, which is needed for the pre-drilling.

Ballasted foundations

Known for being the most expensice method for building a PV foundation, nowadays prices become a more viable option than before. Areas with highly refusal rate in tandem with a low soil cohesiveness, where the other methods aren’t useful, might be installed via the ballasted foundations. Here the soil settling, erosion and heaving must the considered when calculating the cost-efficiency. 

FR+PV's most preferred method

Since we’re aiming to propose the best relation quality-price, we usually try to offer always foundation built via the Driving Piles method. This help us provide a time and money saving individual proposal to each of our customers, of course if the soil’s type is corresponding to the choosen technic.
