Project Description
The existing waterproofing system consists of 1.8mm thick PVC membrane which fixed on the composite roof decking by tie bars at Hong Kong International Airport Terminal 1 is found to be damaged. The Hong Kong Airport Authority decided to install an additional waterproofing membrane on top of the existing system in order to provide a durable new waterproofing system.

Project Requirement
The project include design, supply and installation of an additional roof waterproofing membrane on top of the existing PVC sheet membrane waterproofing system of Terminal 1 roof.

The loading of the additional waterproofing system to be imposed on the roof shall not exceed 2.5kg/m², while its fixing system shall satisfy the design wind pressure with the highest figure is 8.5kPa

Sika Solution
Sarnafil® S327-15L membrane is clamped by polymeric batten strip, Sarnarail and stainless steel fasteners. Sarnafil® Metal Sheet and Sikaflex® AT Sealant are installed along the roof edge profiles and skylights. Sikaplan® Walkway is installed as maintenance protection
