The HECO adjustable feet are made from high-quality hard plastic polypropylene and are used as a substructure for terrace constructions where significant unevenness needs to be compensated. These durable and weather-resistant adjustable feet are suitable for all materials that are considered for a terrace substructure. When a terrace is built on a surface with a greater slope, the HECO adjustable feet provide an easy and quick way to level the surface. Furthermore, the latest generation is capable of compensating slopes of up to 8% thanks to its movable head. This saves a considerable amount of time in what would otherwise be a very labor-intensive alignment of the support surfaces.
