Safety Instructions

A solid foundation is essential for your greenhouse to withstand various weather conditions and protect your plants. It serves as a load-bearing base, ensuring stability and security. Additionally, a proper foundation contributes to the longevity of your greenhouse. Common foundation types include strip foundations made of concrete, concrete slabs or prefabricated concrete blocks, point foundations made of concrete, and laying concrete slabs.
