The DMX Drain 5M is a waterproofing system composed of a geotextile fabric laminated to a high-density polyethylene membrane (DMX AG CCMC #13182-R). Its purpose is to act as a drainage membrane that allows water that seeps towards the foundation wall to flow through the drainage membrane and down to the weeping tile that is placed at the footings of the basement foundation. When it comes to waterproofing the basement foundation, installing the DMX Drain 5M is crucial as it is the final layer that is applied onto the wall after the two layers of Hydro Guard rubberized membrane and a waterproofing reinforcement mesh are installed.
To install the DMX Drain 5M, the membrane is rolled out and placed on the exterior foundation wall with the raised dimples facing away from the foundation wall. Then, the drainage membrane is secured onto the foundation wall using specialized plastic washers and concrete nails. Finally, a special strip is installed to cap off the drainage membrane to prevent water from getting in between the wall and membrane. Once the soil side drainage membrane is properly installed, the weeping tile and 3/4 inch gravel can be added in to complete the waterproofing system.
