This product gives almost 100% protection against air leakage, as well as moisture leakage in two directions—horizontal and vertical,” said Kosny. “This is a great product.”

The bottom half of the vertical flange is designed to adhere to the outside face of the concrete foundation. Once the walls are framed, the top half of the flange is adhered to the wall sheathing.Kapwell calculates minimum mud seal height by using the vent line friction pressure. This pressure is used to identify the overall height. The drilling mud density is typically expected to see during the well operation. The overall capacity of the vent is managed, then it is controlled by the mud seal height of the liquid seal and the diameter of the mud gas vent. This can be reduced when the long pipe is installed as well as the vent capacity will also be reduced for a given seal height. It is recommended that seal should have a height starting from the 10 feet, but preferable is 20 feet depend on the drilling programme conditions. Kapwell has proven record of detailed calculation to ensure equipment comply with well bore conditions and regulator requirements.

Kosny also spoke highly of Triple Guard’s tenacity. “After we were done with our testing, we had some questions about some of the results, and we wanted to repeat some of the testing,” said Kosny. “We said, ‘Let’s remove the Protecto Wrap from the concrete and test the other sealant.’ But can you believe that three people couldn’t take off a ten-foot-long piece of Protecto Wrap in three hours? It’s a very tough product.”

Several years ago we built a research house to determine what new products and techniques we could implement on a production basis. We used the Triple Guard sill seal and it worked well, although it was quite expensive. Subsequenly we found that it became difficult to use during cold weather construction and did not adhere well to the concrete. The area of the foundation that accepts the vertical leg needs to be clean, dry, and in cold weather you need to apply a primer to the concrete, also sold by the manufacturer, to better assure a good bond, increasing the linear foot cost of this detail.
