New to the UK, and I am pouring a grade beam for a workshop that I am building. In Canada (the land of basements), concrete forms are made of 3/4 plywood held together with snap ties, that have slots in them that you slide flat metal bars (waler bars) that hold the forms at a fixed distance. After the concrete sets, you slide the bars out and snap off the ends of the ties.
What do they use in the UK for this purpose?
