heat-weldable waterproofing on bridges

We also provide thorough application of heat-weldable waterproofing on bridges. This is accomplished by:

• Preparing concrete surfaces by shot blasting and sand blasting,
• Performing necessary tests of the foundations: measurement of longitudinal and transversal evenness with a 4 m patch and wedge; measurement of pull-off methods and tearing-resistance of the concrete, measurement of the humidity of the foundations before application of the system primer,
• Applying primer with rollers,
• Applying waterproofing with a multi-flame torch, and torches with one nozzle in hard-to-reach places,
• Conducting acceptance tests required by Specific Technical Specifications (SST) – continuous measurement of climate conditions during the works, foundation adhesion testing using the pull-off method.
