Thermoplastic corrugated stormwater chambers are similar to other types of plastic piping systems in that they are subjected to significant live loads from surface traffic as well as dead loads from earth cover. However, differences in construction — specifically, the fact that chambers are open-bottomed arches — necessitate an understanding of how corrugated stormwater chambers behave…
