Innovative Products to Keep America Dry

PVC consists of three parts: PVC resin, plasticizer, and filler.

St. Louis, MO – We stopped in St. Louis to learn about the exciting products manufactured at the Sika Greenstreak plant. The plant, protected by a Sikafloor epoxy system, has the ability to make a wide variety of waterproofing products. We were given a tour to see how this 24/7 operation works.

Howard Magoffin, the Director of Manufacturing for the plant, has been working at the St. Louis plant for 35 years. He is constantly searching for new ways to optimize processes and improve technology, as he told us “if you’re not moving forward, you’re moving backward.” This includes upgrading the efficient machines used throughout the production process to meet the heavy demand. In addition to the impressive machinery, the plant has a die shop and a fully functional compound production system onsite. The Sika Greenstreak plant has helped a similar Sika plant in Colombia get started. The St. Louis plant sent die molds, compounds, and even two engineers to optimize the processes of the Colombia plant. Sika Greenstreak also does work with the Army Corps of Engineers and the Bureau of Reclamation to repair public water systems, as well as many other important public projects.


There are many interesting products manufactured at the St. Louis Greenstreak plant. We learned about the PEC-Mat, which is made by intertwining strands of PVC monofilaments. PEC-Mats can be used to protect seed and soil during germination without affecting the local ecosystem. Sika Greenstreak can make custom Architectural Concrete Form Liners for a variety of uses. Have you ever seen the wood finish on the exterior of a Bass Pro Shop? That is actually colored concrete set in a Sika Greenstreak Form Liner to look like wood. One of the most popular products, the PVC Waterstops, provides additional waterproofing for foundations in many construction projects. Sika Greenstreak has the ability to make these Waterstops in long, continuous strips to protect larger foundations.

The die faceplates can be changed to produce a specific shape.

Because of the recyclability of the processes, the plant sees a 99.5% material utilization. In combination with the water recovery system for process cooling we can see where the green in Greenstreak comes from.  We are excited to see the new and innovative ways that Sika Greenstreak waterproofing products will be used in future construction projects.
