Special Issue Information

Dear Colleagues,

Leakages in concrete structures or infrastructures are generally overlooked as minor problems in the field of construction, but as of recently, leaking in concrete structures and infrastructure have become more emphasized as a social problem. In addition to the reduction of property asset values and hygienic problems, continued leakage can cause a significant reduction of structural durability. In extreme cases of negligence in maintenance, large infrastructures can collapse. For many types of existing concrete structures, some form of water is always present, so waterproofing must be properly installed to ensure the safety, durability, and functionality of the structure. In concrete engineering, high-quality watertight concrete is often used to prevent leakage, and waterproof engineering employs the usage of various waterproof materials to prevent water leakage. However, in reality, the effects of such waterproof measures are not being properly displayed, and further studies and evaluation are required.

This journal invites authors to publish papers regarding development of successful waterproofing construction or materials for the protection of concrete structure roofing and below-grade walls. When it comes to promoting an active discussion on how to establish a systemized and internationally standard waterproofing method of concrete structures, we are hopeful that this Special Issue can provide a starting base for such an academic platform.

The topics of interest include but are not limited to;

  • Performance of waterproofing materials for roof and below-ground concrete structures;
  • Anti-corrosive waterproofing materials for concrete water tanks;
  • Root-penetration resistance materials for waterproofing of artificial ground;
  • Required performance properties for waterproofing materials and execution methods;
  • Evaluation methods for waterproofing materials;
  • Repair materials for water-leakage cracks in concrete structures;
  • Prevent technology of water leakage for concrete structures;
  • Sealant technology;
  • Other technologies related to waterproofing materials, execution methods, test methods, etc.

Evaluation Method of Relative Humidity Changes in Below-Grade Concrete Structure Space Depending on Different Waterproofing Material and Installation Method
Materials 2020, 13(3), 742; https://doi.org/10.3390/ma13030742 - 06 Feb 2020

An evaluation method for assessing the difference in the relative humidity (RH) control performance of waterproofing material is proposed. For a demonstration of this evaluation method, two waterproofing materials (urethane coating and cementitious waterproofing material) installed with different methods (positive and negative side of concrete structure respectively) are exposed to temperature conditions representing three seasonal conditions: Summer (40 °C), spring/autumn (20 °C) and winter (4 °C). Condensation level changes on the inner side of the waterproofing material installed specimen is measured, and for derive criteria for comparison, three parameters based on the average RH, intercept RH (derived from a linear regression analysis of RH measurement), and maximum relative humidity are derived for each different waterproofing material installed specimen. Based on quality specification for underground concrete structures, the demonstration evaluation establishes provisional standard criteria of below 70% RH, and all three parameters are evaluated to determine whether the tested waterproofing material/method complies to the performance requirement. Additional analysis through linear regression and cumulative probability density graphs are derived to evaluate the RH consistency and range parameters. The evaluation regime demonstrates a quantitative RH analysis method and apparatus, and a newly designed evaluation criteria is used to compare the RH control performance of positive-side installed urethane waterproofing materials and negative-side installed cementitious waterproofing material.

Oil Leakage Evaluation for Selection of Emulsion-Based Non-Curable Synthetic Polymer Rubberized Gel (ENC-SPRG) as Waterproofing Material in Underground Structures

A revised oil leakage evaluation regime is proposed in response to the oil leakage problems of emulsion-based non-curable synthetic polymer rubberized gel (ENC-SPRG) used as a waterproofing material in concrete slabs of residential underground structures. Oil leakage from ENC-SPRG can cause significant economic and environmental damage. As ENC-SPRG waterproofing material is relatively new in the global waterproofing market, a systematic quality control for ENC-SPRG products being manufactured and exported globally is currently non-existent. For the selection of optimal ENC-SPRG, six assessment parameters comprised of averaged and daily average oil leakage mass, averaged and daily average filler content settlement, oil leakage area, and oil leakage duration are proposed. Five ENC-SPRG product specimens are tested to obtain the property values of each parameter. The property values derived from the test results are compared between the tested ENC-SPRG product specimens. With the demonstration of this evaluation regime, a quantified method for a comparative assessment of ENC-SPRG type waterproofing materials is established. Full article
