B.
Roll out drainage composite system material with the geotextile filter fabric side down, directly on the subgrade or concrete working slab, covering entire area as directed by construction documents.
C.
Butt adjacent panels and lap geotextile fabric. Use a butyl tape or duct tape to seal the plastic panel joints (sealing the laps is not required if waterproofing is installed on top of the Mapedrain).
3.5
BACKFILL FOUNDATION WALL INSTALLATION - GENERAL
A.
At the base of the wall, place Mapedrain TD foundation drain horizontally oriented standing up tight to wall with the dimple side facing out over the previously installed MAPEI waterproofing system.
1.
To install Mapedrain over Mapeproof bentonite geotextile composite waterproofing, use fasteners compatible with the substrate and 1 inch washers approximately 24 inches (60 cm) on center to secure Mapedrain TD.
2.
To install Mapedrain over Mapethene self-adhered sheet waterproofing, use Mapebond 740 Aerosol Spray Adhesive to secure Mapedrain TD.
3.
Use Mapedrain TD accessory fittings, as required, to form a continuous installation. Install Mapedrain TD discharge outlet fittings to connect to discharge pipes as required for the project.
B.
Install the bottom course of Mapedrain drainage composite (flat plastic core side against the wall/waterproofing) with the Mapedrain bottom core edge in contact with top core edge of Mapedrain TD. Secure extra fabric flap of Mapedrain extending down the top front edge of Mapedrain TD to prevent the passage of soil into the core at the connection.
1.
To install Mapedrain over Mapeproof bentonite geotextile composite waterproofing, use fasteners compatible with the substrate and 1 inch washers approximately 24 inches (60 cm) on center to secure Mapedrain.
2.
To install Mapedrain over Mapethene self-adhered sheet waterproofing, use Mapebond 740 Aerosol Spray Adhesive to secure Mapedrain.
