Shea Concrete Products is excited to announce our 3rd “Virtual” Technical Engineering Seminar that is available through our Podcast (The Precast Podcast) and will allow for an online library of technical seminars that professionals can access to gain industry knowledge and stay current with professional development credit hour requirements.

This “virtual” seminar opportunity allows for participants to obtain three (3) individual professional development credit hours as follows:

1. 1.0-Professional Development Hour (PDH)

2. 1.0-“NHDES Subsurface Systems Bureau” Credit Hour (NHDES Subsurface Designers & Installers)

3. 1.0-“NEIWPCC” System Inspector (SI) Training Contact Hour (TCH)


Presentation Summary:    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.  In this episode 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
