EPS (expanded polystyrene), often referred to as Styrofoam, can be cut
into almost any shape and size. For this project in Austin Texas, the
contractor had 50 pipes that needed to have the ends protected during
installation of concrete. The pipes were cut at a 45 degree angle. The
solution was to fill them with cylindrical cut pieces of EPS, also cut
at a 45 degree angle on both ends and a little duct tape to hold them in
place. Everything worked as planned.
