GUIDE SPECIFICATION FOR WATERPROOFING 15.11
PART 3 EXECUTION

3.01 MANUFACTURER'S INSTRUCTIONS/RECOMMENDATIONS
A. Compliance: Comply with manufacturer's product data, including product technical bulletins,
product catalog installation instructions and product packaging instructions.
3.02 EXAMINATION

A. Site Verification of Conditions: Verify substrate conditions (which have been previously
installed under other sections) are acceptable for product installation in accordance with
manufacturer's instructions. Do not proceed with drainage installation until substrate
conditions are acceptable for compliance with manufacturer's warranty requirements.

3.03 PREPARATION
A. Adjacent Surfaces Protection: Protect adjacent work areas and finish surfaces from damage
during installation operations.
B. Concrete Surface Preparation: Prepare concrete surfaces to receive drainage composite.
Surfaces shall be smooth, free of depressions, voids, protrusions, clean and free of other
surface contaminants which may impair the performance of drainage and manufacturer's
warranty requirements.
1. Cast-in-Place Concretes: Decks shall be monolithic, smooth, free of voids, spalled
areas, laitenance, honeycombs, and sharp protrusions. Refer to Division 3 Concrete
Section for concrete strength, density, finish, curing methods and other concrete
requirements.
2. Precast Concrete Decks: Decks shall be mechanically secured to minimize
differential movement and each joint between precast units shall have an installed
backer rod. Grout precast units as recommended by manufacturer.
3. Shotcrete: Surface shall be monolithic and smooth with no indulations, irregularities
or exposed wire mesh.

D. Substrate Cleaning: Clean substrate which is to receive drainage. Remove loose debris and
other harmful contaminants which will affect performance of drainage composite.
