So there's a 50 mil layer can see there. So there's a 50 mil layer of a very weak concrete. It's nothing of a very weak concrete.
It's nothing more than you know to keep the site more than you know to keep the site clinical and for level control. So the clinical and for level control.So the blind is laid the blind is laid to a blind is laid the blind is laid to a level. That level then determines our level.
That level then determines our start point for the rest of the start point for the rest of the construction. So it's crucial that it's construction. So it's crucial that it's accurate, but it also it doesn't matter accurate, but it also it doesn't matter because it's a sacrificial product.
So because it's a sacrificial product.So it doesn't have to be anything it doesn't have to be anything particularly special. The concrete particularly special. The concrete doesn't need testing or anything like doesn't need testing or anything like that.
It's purely as a clinical area for that.
