Safety instructions

In order for your greenhouse to withstand wind and weather and to protect your plants from the elements, a foundation is essential. The foundation serves as a load-bearing base and thus ensures a firm and secure stand. The foundation also ensures your greenhouse a long life. Common foundations for greenhouses are: strip foundation made of concrete, concrete slabs or prefabricated concrete blocks, point foundation made of concrete, and the laying of concrete slabs.
