From 1910 to today, a legacy of quality work

By Sika Corporation. 

Learn how Sika’s liquid applied roofing and waterproofing played a crucial role in a historical renovation. 

Sika’s history began in 1910 with Kaspar Winkler inventing Sika-1, a quick-setting waterproofing admixture for mortar. From this very first product, Sika has been used in unique and important projects. For example, Sika-1 was used to waterproof the Gotthard Tunnel which enabled the Swiss railway company to connect Northern and Southern Europe. As Sika has grown and continued developing their products, they continue to tackle unique projects with passion and determination.  

One such example of this is a 2022 project in Dallas, Texas. This project saw the general contractor, Texas Roof Management, working with Tim Bush, a technical field services representative for Sika. Keep reading to learn about this project and how Sika products contributed to the solution. 

Project description 

Dallas county planned for a renovation of the Dallas County Records Building Complex, which includes three historic buildings. Built from 1915 to 1955, this complex is a landmark with distinctive architecture and rich with storied history.  

Unique problem 

The project’s main goal was to keep the building intact with its historic significance while modernizing it for efficiency. Part of the challenge to make the roof more energy efficient was to revive it without tearing it off and replacing it.  

Project solution

Sika® Reemat Premium was also used as a versatile, conformable solution to waterproof and preserve the unique vertical and horizontal detail conditions. The RoofPro system also provides the solar reflectance the existing roof could not. This high-quality sustainable solution will provide cost effective energy savings and protect the roof for years to come. 

The products used include Sikalasitc®-641 LoVOC, Sikalastic® EP Primer/sealer, Sika® fleece 170, Sika® Flexitape heavy and Sika® reemat premium.
