The ground adjacent the wall is left substantially intact. The wall building device has cross-sectional dimensions being substantially equal to the dimensions of at least a part of the cross-section of the wall or wall part. The wall or wall part is formed by injecting a hardenable material (44) behind the wall building device. The ground in the area adjacent the front part of the wall building device is removed and discharged. <IMAGE>
