Structural body comprises a concrete core 104 and a cap 106 around the opening. A first wrap 102 is wrapped under tension around the concrete core 104 and a portion of the cap to form a continuous water resistant barrier around the outer surface of the concrete core. A second wrap 103 can be wrapped under tension around the inner surface of concrete core to form a continuous water resistant barrier around the inner surface of the concrete core 104. Structural body can be formed as a pipe with a male and female ends to interconnect multiple pipes. The joint formed between two structural bodies has a continuous water resistant barrier that prevents the environment from contacting the concrete core. |
