From joints to walls, the need for holding water in an assembled concrete structure is an increasingly necessary task. Infiltration can overload the system, and exfiltration may cause
contamination of soils. This presentation will explain the differences between watertight (proof) and damp-proof. Joints are often thought of as a concern for water passage; concrete is a porous material and can contribute to leakage as well. You will learn:
- The types of joints available for pipe and precast
- The hydrostatic resistance of joint materials
- That concrete contains a network of pores
- The purpose of coatings to provide a barrier
- How admixtures can provide hydrostatic water resistance
