We offer bases for (almost) every subsurface. Our 3p-Technology systems come with a 300-mm-long base as a standard. When using high paving stones or fitting it into soft, clayey subsurfaces, we recommend bases with lengths of 500 mm. Very important: The functionality of the 3p-Technology is considerably dependent on the quality of the foundation. Please see also the installation instructions, which are available in the downloads area of our online shop. You are welcome to contact us at any time if you have any questions.
