Summary and Description:
The DD-Series Strip Seal System is designed for use as a “stand alone” expansion joint system or in conjunction with membrane waterproofing in the sealing of expansion joints in building complexes. It features a preformed sealing element affixed to aluminum rails and clamped tightly by formed plates. The system can be used with our Polycrete elastomeric system, pavers or other substrate materials. Once installed, this system provides a watertight seal, while flexing in response to changes in joint width.
The formed top plate clamps the flaps of the sealing element permanently in place on top of the aluminum rails. The flaps of the seal are continuous so that discontinuities between metal parts are kept watertight. The sealing element is extruded from a thermo-rubber material, which can be heat-fused to seal directional changes.
