The DrainGreat Co. LLC
DrainGreat securely connects to drainboard without the use of duct tape or pins and does not come loose even during shotcrete application. The connection ring is much bigger than the 3-inch (7.6 cm) PVC pipe it drains to, thus increasing the amount of flow that can be handled. DrainGreats are quick and easy to install and are made in the USA. DrainGreats were developed for soil nail walls by a foundation contractor who was looking for a better way to connect a PVC pipe to a drainboard. DrainGreats can also be used in other applications where it is necessary to transfer fluid from drainboard to a pipe.
