Not sure I would build it on sand Wahaj... they are usually easier to put together than explain but it really is a two person job... :)
When i put my greenhouse up it came with a base which was obviously the length and width of the greenhouse and about 4 inches high.You bolt this together and i had four spikes which you bolt into each corner.You need to dig holes in each corner and then the spikes go into the holes and you pour concrete around them ensuring your base is level.Leave the concrete to go off and away you go.Sorry it it doesnt make sense hopefully it may be of some help.
Shouldn't the spikes be set in place BEFORE you pour the concrete? Otherwise you'll have to drill holes and concrete them in anyway.Maybe someone will tell me I'm wrong?Tricia
Are the spikes attached to the base frame ? if so make sure you have a spirit level handy, mine are on base of concreat and topped with single layer of bricks old style.Is it a glass one or polycarbe, mine is glass which hubby putty with the metal clips so they did not slip.
Have you done your base yet wahaj??Have to confess I sat reading your post with a smug smile on my face ;D ;D as I remember the nightmare I had building mine.I don't envy you but it will be worth it in the end.
