Along at least a part of the foundation post, reinforcement devices are incorporated. A durable material is placed somewhat beneath the ground surface around the foundation post comprising a mainly tube-shaped casing. This material is plastic or metal, and acts as a supplement to the reinforcement devices. Clamping devices are applied to the foundation post, and propelling parts are fitted between the clamping devices and an upper edge of the casing, in order to force the tube-shaped socket and the foundation post into the ground. Around the foundation post, are fitted a first and second socket cement, which together form the tube-shaped socket.
