A Day with Geosynthetics - June 6, 2018

In late 1960s, the introduction of engineered synthetics, i.e. geosynthetics, into soil was a major breakthrough in improving the engineering behavior of soil. While the theories of classic soil mechanics by Coulomb, Rankine and Terzaghi have not been changed significantly with time, adaptations to these fundamental principles have been developed to take geosynthetics into consideration. This technical symposium is an occasion where you will be able to appreciate various types of geosynthetics, including geotextile, geogrid, geodrain, geomembrane, etc., to understand their material characteristics, to learn the applications and designs of these products, to review case histories, to understand the current limitations of geosynthetics and to look forward future developments.

Eight presentations will be made by practicing experts of this specialty field in this full-day technical symposium to cover different aspects of geosynthetics, including an overview & history of geosynthetics, conductive HDPE waterproofing membrane, geosynthetic cementitious composite mat, prefabricated band drain, slope protection steel cable mesh, international conformance testing of geosynthetics, drainage geocomposite, and reinforced soil construction development.

You will also have an opportunity to obtain hands-on experience on material interactions during the symposium, such as conducting a leak spark test for geomembrane on your own, witnessing various types of geotextile filtering, modelling behavior of geogrid reinforced block wall etc.

Use of Geosynthetics in Hong Kong: An Overview - Leo K. Overmann

Geosynthetics are "man-made" materials have common applications that impact on us daily. But these applications, as dictated by the Government, have various applications and quality issues. However, there are also countless other civil and environment applications and innovative technologies associated with these geosynthetics materials.

Design with Drainage Geocomposite - Alan Bamforth

Geosynthetics drainage system is a feasible alternative to drainage stone in different structural and heavy civil applications. Successful applications depend on several factors and the design criteria. We will look at a few examples in this presentation.

CQA Conformance Testing Practices for Geosynthetics - Corazon B. Queja

CQA (Construction Quality Assurance) is employed to make sure that the designs are properly followed, sites are properly prepared, and all materials are within specifications. This paper shows how geosynthetic testing is being applied to various projects in Hong Kong.

Steel Cable Rock Mesh: Active Slope Protection - Marco Cerro

Secured drapery systems are composed of a steel rockfall mesh and a pattern of nails disposed with different configurations along the slope. The goal of this solution is to stabilize the superficial portion of the rock slope (by the nails) and keep in place the unstable rock material (by the mesh). This presentation describes a simplified design approach, which combines the in-situ evidence and the experience of designers with the results of full-scale tests on mesh.

Prefabricated Band Drain Installation - Dirk-Jan den Ouden

When soil improvement by consolidation is required, various matters are to be considered when selecting the prefabricated vertical drains (PVD), as well as suitable installation equipment. By providing in-depth knowledge on the background of PVD, the types of drain, installation practices and quality control, one will have a better understanding on the various requirements when considering the use of vertical drains.

Permanent Leak Location Liner System for Environmental Containments - Hermann Ng

HDPE geomembrane plays an important role as quality containment, which, in turn, relies on the integrity of the seam on a long-term basis. A new generation leak location liner system, in association with permanent liner integrity monitoring technology, has been proven to be effective in enhancing the sustainability of geomembrane lined facilities. An introduction is presented.

Geosynthetic Cementitious Composite Mats (GCCM)- Michael Chong

The presentation is an introduction of Geosynthetic Cementitious Composite Mats, it's unique characteristics, advantages, applications, installation and case studies.

Reinforcing soil with Geosynthetics - Albert T. Yeung

Reinforced Earth© construction debuted in France in 1966. However, it was first used in Hong Kong in 1981. Since then, the development of the application of the technology in Hong Kong has been slow despite tremendous advance in the technology overseas. Conservative mindset, misconception of the behavior of polymeric material and lack of academic training are still vivid. The presentation will give an overview of the development of reinforced fill construction in Hong Kong.
