PART 3 — EXECUTION

3.1 EXAMINATION

1. 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

1. Verify substrate is prepared according to manufacturer’s recommendations.
2. Mask off adjoining surfaces not receiving methane barrier/waterproofing to prevent spillage or over spray affecting other construction.

3.3 PREPARATIONS AND TREATMENT AT TERMINATIONS AND PENETRATIONS

1. Prepare vertical and horizontal surfaces at terminations, at penetrations through methane barrier/waterproofing materials to ASTM C 898 and manufacturer’s recommendations.
2. Apply two coats of ECOLINE-T on both sides of top and bottom protection course layers (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.

1. Terminations should be treated 6 inches up vertical and 6 inches on horizontal.
2. Penetrations should be treated in a 6-inch radius around penetration and 3 inches onto penetrating object.

3.4 METHANE BARRIER/PROTECTION COURSE BOTTOM INSTALLATION

1. Install ECOSHIELD-P over substrate material in one direction with six-inch overlaps

2. Secure the ECOSHIELD-P seams by applying ECOLINE-S between the overlapped sheets.

3.5 METHANE BARRIER/WATERPROOFING APPLICATION

1. Set up spray equipment according to manufacturer’s instructions and place spray-markers in field of bottom protection course.
2. Mix materials according to manufacturer’s instructions.
3. Start installing waterproofing in presence of manufacturer’s technical representative.
4. Apply methane barrier/waterproofing, according to manufacturer’s recommendations, by spray (ECOLINE-S) or roller (ECOLINE-R).
5. 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 (1.2 mm).
6. Apply methane barrier/waterproofing to prepared wall terminations and to the horizontal surface of the bottom protection course to a thickness indicated by the placed spray-markers and according to manufacturer’s recommendations and details.
7. Verify film thickness of waterproofing every 100 sq./ft. (9.3 sq./m).

3.6 METHANE BARRIER/PROTECTION COURSE TOP INSTALLATION

1. Install ECOSHIELD-PP protection course perpendicular to the direction of the bottom course with overlapped seams over nominally cured membrane no later than recommended by manufacturer and before starting subsequent construction operations.
2. Secure ECOSHIELD-PP protection course seams by applying ECOLINE-S the overlapped sheets as recommended by the manufacturer.

3.8 FIELD QUALITY CONTROL

1. 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.
2. 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

1. Cure waterproofing according to manufacturer’s recommendations. It should be noted normal curing time is 24 to 48 hours to achieve a permanent water barrier. However, in some conditions such as a saturated substrate, extremely cold conditions and/or high humidity, the full adhesion of the membrane may be delayed. The length of delay may be subject the membrane thickness and severity of conditions.
2. Take care to prevent contamination and damage during application stages and curing.
3. Clean spillage and soiling from adjacent construction using cleaning agents and procedures recommended by manufacturer of affected construction.
