Ours survived till Thursday but was getting a battering as the ground is not hard enough so it was taken down before the wind took itWe’re thinking of getting a jormax windbreak. We’re at Topsham and have had 50 mph winds. One couple left their jormax up overnight, presumably by accident the first night but it didn’t budge. They didn’t risk it a second night though!

To answer the original question, a lump hammer as the poles will go through some seriously hard ground but not with a rubber hammer.
