Product Utilization and Description
The DD-400 LP is a low profile joint system especially designed to be used with membrane waterproofing in the sealing of expansion joints in building complexes. It features a preformed sealing element affixed to aluminum rails and clamped tight by formed plates. The system can be used with a Polycrete Elastomeric Concrete header material or a separate preformed sheeting can be added to mesh wit the membrane material. Once installed, this system provides a watertight seal while flexing in response to changes in joint width.
The sealing element is extruded from a Thermorubber material, which can be heat-fused to seal directional changes. This is particularly important where the system is used in below grade applications for which it would prove particularly expensive to excavate to check and/or fix leaking conditions.
