Dimple Mat / Membrane
Tag-Drain Dimple Mats, also known as dimple membranes, help keep moisture out of the foundation walls by draining excess water. The Tag-drain dimple mat is designed as a flexible subsoil drainage mat for roof gardens, landscape decks or plazas, and planter boxes.
Wall Tag leads the industry in manufacturing and distributing a wide range of drainage cell varieties, including our first-grade tag drain dimple mats that can withstand hydrostatic pressure. Our Tag-Drain Dimple Mats make the installation easy over any foundation type, such as concrete block, poured concrete, insulated concrete, and preserved wood foundations.
Weighing less than 1 kg/m2, Tag-Drain Dimple Mat reduces the weight loaded on concrete decks compared to gravel drainage layers. This drainage mat is relatively lightweight, making it simple to handle and move around.
Tag-Drain Dimple Mat has a free surface, which is at least 90% permeable to water, and a high flow rate of 60 lit/min/m at a 1% hydraulic gradient, allowing it to drain off seepage water efficiently.
Tag-Drain Dimple Mat has a compressive strength of 200kN/m2 that can withstand installation loads and soil loadings. Its 1-metre width saves installation time and can be cut to fit any shape or profile.
