PART 3 EXECUTION
- Examine substrates, areas, and conditions under which waterproofing systems will be applied, with Installer present, for compliance with requirements. Do not proceed with installation until unsatisfactory conditions have been corrected.
3.2 SURFACE PREPARATION
- Clean and prepare substrate according to manufacturers recommendations. Provide clean, dust-free, and dry substrate for waterproofing application.
- Mask off adjoining surfaces not receiving waterproofing to prevent spillage or over spray affecting other construction.
- Close off deck drains and other deck penetrations to prevent spillage and migration of waterproofing fluids.

- Prepare vertical and horizontal surfaces at terminations, at penetrations through waterproofing material, and at expansion joints, drains, and sleeves according to ASTM C 898 and manufacturers recommendations.
- Apply two coats of ECOLINE-T (30 mil each) and embed a joint reinforcing strip in preparation coat and apply a second coat over embedded joint reinforcing strip ensuring its complete saturation and covering. (See detail drawing B).
- Terminations should be treated 6 inches up vertical and 6 inches on horizontal.
- Penetrations should be treated in a 6-inch radius around penetration and 3 inches onto penetrating object.
3.4 PREPARATIONS AND TREATMENT OF JOINTS AND CRACKS

(See detail drawing C & D)
- Horizontal - Install sheet flashing over reinforced ECOLINE-T joint to deck and wall substrates where indicated or required according to waterproofing manufacturers recommendations.
(See detail drawing C & D)
3.5 WATERPROOFING APPLICATION
- Set up spray equipment according to manufacturers instructions.
- Mix materials according to manufacturers instructions.
- Start installing waterproofing in presence of manufacturers technical representative.
- Apply waterproofing, according to manufacturers recommendations, by spray (ECOLINE-S) or roller (ECOLINE-R).
- Apply one spray coat of ECOLINE-S or four roller coats of ECOLINE-R waterproofing to obtain a seamless membrane free of entrapped gases, with an average dry film thickness of 80 mils (1.5 mm) and a minimum dry film thickness of 60 mils (1.3 mm) at any point.

- Verify film thickness of waterproofing every 100 sq. ft. (9.3 sq. m).
3.6 PROTECTION COURSE INSTALLATION
- Install ECOSHIELD-E10 protection course with overlapped seams over nominally cured membrane no later than recommended by manufacturer and before starting subsequent construction operations.
- Secure ECOSHIELD-E10 protection course seams with ECOSHIELD Tape and attach to adhesive strips (sheet flashing that does not penetrate waterproofing) as recommended by manufacturer.
3.7 DRAINAGE PANEL INSTALLATION
- Place and secure drainage panels to substrate according to manufacturers written instructions. Use adhesives and adhesive strips (sheet flashing that does not penetrate waterproofing) as recommended by manufacturer. Overlap edges of dimpled core and ends of geo-textile to maintain continuity. Protect installed panels during subsequent construction.
3.8 FIELD QUALITY CONTROL
- Membrane may be checked for coverage with a lightly oiled, needle nose depth gauge, taking four (4) readings over a one square inch area, every 500 square feet. Record the minimum reading. Mark the test area for repair.
- Test areas are to be patched over with ECOLINE-S to an 80 mil minimum dry thickness, extending a minimum of one inch (1") beyond the test perimeter.
3.9 CURING, PROTECTING, AND CLEANING
- Cure waterproofing according to manufacturers recommendations, taking care to prevent contamination and damage during application stages and curing.
- Clean spillage and soiling from adjacent construction using cleaning agents and procedures recommended by manufacturer of affected construction.
