deploying a float tool comprising one or more one-way valves into a well as part of a casing string;
pumping cement into the casing string in the well;

preventing the cement from flowing in an uphole direction through the first wiper plug using a valve element positioned in the first wiper plug;
pumping fluid through the first wiper plug in a downhole direction after deploying the first wiper plug down to the float tool;
deploying a second wiper plug through the casing string until the second wiper plug engages the first wiper plug; and
rupturing a rupture disk in the second wiper plug by increasing a pressure in the casing string.
