DRAINAGE MAT

PART 1 - GENERAL

1.1 Scope

Work under this section consists of installing a prefabricated drainage mat in the following areas:

Plaza Decks: in localized repair areas, as a supporting layer directly beneath the cast-in-place topping slab.

Transition Areas: Between cast-in-place slab-on-grade and supporting angle on basement wall at perimeter of plaza deck (see details).

Submittals: Data illustrating and describing the all the materials of the system and verifying their conformance with the requirements of this specification.

PART 2 - PRODUCTS:

Materials: The drainage mat shall be a prefabricated, composite drainage panel consisting of a three-dimensional. High impact, polystyrene core with a nominal one inch flange on one longitudinal edge and a polymeric sheet adhered to the flat side of the core and a non-woven filter fabric on the other side. The product shall conform to the following material properties:

PART 3 - EXECUTION:

Plaza Deck Areas: The drainage mat shall be placed horizontally on clean, smooth substrate as shown on the drawings with no projections or kinks in the material. During placement of concrete overlayment, care shall be taken to prevent damage to filter fabric or core material. Salient characteristics are per previous table.

Transition Areas: Place the drainage mat as detailed on the drawings. Plae the flat side

(not filter material side) against the waterproof membrane under plaza deck pavement as shown. Continue mat down to support angle placement over filter fabric used as trench drain wrap. Secure the drainage mat in place as recommended by the manufacturer to prevent any displacement during backfilling operations.
