 The product that we are doing, the homes that people are buying into, start off with a good foundation. And I mean that metaphorically and literally. You cannot build something for the future that doesn't have good bones. And PPC and their cement that they produce is integral to the structure of our homes, the building thereof. Literally from the concrete foundations, the mortars that bond the bricks together, the plasters that go there on, the screeds that get placed on the floors. All of those products have to be long standing. And we cannot achieve that without a quality product, as in PPC cement. But more than that, working on the models around the mixed ratios of all of those products. And that's where we found the support from PPC being wholehearted. We've actually got our maintenance manager Vincent, who we laugh and joke about having his own coffee cup in the PPC canteen. Because he's in their laboratory so often. But there's a purpose and a reason behind that. They're trying with us to develop the product to the best of its potential. And in so doing creating a product that has a long life to it.
