Background

The example project shows a specialist application of waterproofng materials applied to several buildings at Bangkok’s new international airport, Thailand. The buildings included, were the airport information management system building, roof of the main control tower and the main air traffc control buildings, which house very sophisticated and important computer equipment. The total area was in excess of 2,500 m2. Trepax was chosen as the supplier and applicator for this project due the technical nature of the installations and our experience and expertise in applying such high value waterproofng systems to important structures.

Project Overview

The new airport being a national show case asset of Thailand was a prestigious project and Trepax were delighted to be associated with it. The project itself presented many technical and logistical problem from working at extreme heights in high winds and managing to protect the areas in a tropical climate from heavy rainfall. The reason for using a high value waterproofng system was to protect the electronic assets in the buildings associated with safety managing the airports control systems from the risks of water damage. Correct installation and verifcation through leak tests were paramount in confrming the system would work as designed.

System

The system was based on EPDM sheet and was supplied by one of our USA based suppliers who are well known in the feld of EPDM. This system had many complicated details and fastening system with many sub materials to be applied at these details. Correct knowledge and experience in how to prepare the surface, prepare details and apply the membrane to general areas, details and terminations were essential to provide a long term leak free solution to protect the buildings important assets. The waterproofng system was one part of a complete system with insulation and in some cases concrete toppings applied over metal roof decks which were installed by our service teams.
