Emseal DSM-FP: Plaza Deck Joint System

Emseal DSM-FP is a plaza-deck to solid-slab or wall expansion joint, Emseal DSM-FP is watertight and purpose designed for use in plaza decks particularly where a split-slab meets a solid slab or wall. Questions? Contact Us.

DSM-FP extends the use of the DSM System to waterproofed split-slab deck designs through combination with our FP (for plaza) mounting rails and side flashing sheets that integrate with the deck waterproofing membrane and contain the wearing course.

The material that bridges and seals between the FP mounting rails is EMSEAL’s DSM System which is a silicone-and-impregnated-foam hybrid sealant that ensures watertightness, absorbs sound, dampens vibration and offers uncomplicated installation.

In contrast to buried joint systems, EMSEAL’s FP Systems prevent the buckling of pavers or other hardscaped wear course materials and will not suffer flex-fatigue failure at the waterproofing membrane tie-in.

  • Watertight & Traffic Durable
  • ADA Compliant
  • Integrates through its side flashing sheets with the deck waterproofing systems of split slab, concourse, and plaza deck design.
  • Uniquely suited to joint openings between split-slab and solid slab construction
  • Uniquely suited to deck-to-wall and deck-to-column conditions in split-slab construction

Watertight – Emseal FP (For Plaza) systems are purpose-designed to provide watertight joint sealing and watertight integration with the buried deck waterproofing membrane. The DSM System material is installed between the faces of the FP retainer legs with the silicone bellows facing the weather to ensure watertightness in the joint gap. The tensionless silicone bellows are installed essentially flush to the deck surface just below the stainless steel capping strips thereby ensuring watertightness at the wear-course surface. This eliminates the need for secondary moisture barriers and gutter systems.

Continuity of Seal – All EMSEAL expansion joint systems feature continuity of seal through changes in plane and direction –– an essential performance differentiator. Fabricated transitions from deck to wall, at curbs, sidewalks, parapets, tees, and crosses are available with DSM-FP.
