Customer had a few cracks along the basement wall and when it would rain, water would seep in through the cracks. To take care of this we used our pattened product called FlexiSpan. Flexispan is a 2 part system, a crack sealant and a hidden, drainage channel that when installed with Waterguard,will direct any leaking water to your sump pump. The drainage channel is permanently sealed to the foundation, and if there is any wall movement, the channel will flex with it.
