    PART 3 EXECUTION

    3.1 EXAMINATION

    A. 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

A. Clean and prepare substrate according to manufacturer’s recommendations. Provide clean, dust-free, and dry substrate

    for waterproofing application.

    B. Mask off adjoining surfaces not receiving waterproofing to prevent spillage or over spray affecting other construction.

    C. Close off deck drains and other deck penetrations to prevent spillage and migration of waterproofing fluids.

    D. Remove grease, oil, form release agents, paints, and other penetrating contaminants from concrete.

    E. Remove fins, ridges, and other projections and fill honeycomb, aggregate pockets, grout joints, tie holes, and other

    voids with ECOLINE-R, hydraulic cement, or rapid-set grout.

    3.3 PREPARATION AND TREATMENT AT TERMINATIONS AND PENETRATIONS

    A. Prepare vertical and horizontal surfaces at 90-degree terminations, at penetrations through waterproofing material, and

    at expansion joints, drains, and sleeves according to ASTM C 898 and manufacturer’s recommendations.

    B. Apply two coats of ECOLINE-R (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 3 inches on each side for both vertical and horizontal.

    2. Penetrations should be treated in a 3 inch radius around penetration and 3 inches onto penetrating object.

    3. Penetrations should be additionally fastened with polypropylene zip tie or other suitable clamp.

    3.4 PREPARATIONS AND TREATMENT OF JOINTS AND CRACKS

    A. Prepare, treat, rout, and fill joints and cracks in substrate according to ASTM C 898 and waterproofing manufacturer’s

    recommendations. Remove dust and dirt from joints and cracks complying with ASTM D 4258 prior to coating

    surfaces.

    B. Less than 1/16 in. - Apply two coats of ECOLINE-R waterproofing, 6 inches on each side of joint or crack and embed a

    joint reinforcing strip in preparation coat and apply a second coat over embedded joint reinforcing strip ensuring to

    complete saturation and covering.

    C. Greater then 1/16 in. Rout joint or crack, install backer-rod and sealant to bring flush to surface. Apply a coat of

    ECOLINE-R to joint or crack, 6 in. on each side, embed a joint reinforcement strip and apply a second coat, where

    indicated or required according to waterproofing manufacturer’s recommendations.

    3.5 WATERPROOFING APPLICATION

A. Set up spray equipment according to manufacturer’s instructions if spray-applying material.

B. Mix materials according to manufacturer’s instructions.

C. Start installing waterproofing in presence of manufacturer’s technical representative.

D. Apply waterproofing, according to manufacturer’s recommendations, by spray (ECOLINE-S) or roller (ECOLINE-R).

    E. Apply a base spray coat of ECOLINE-S or three 27 mil (wet) coats of ECOLINE-R, to obtain a seamless membrane

    free of entrapped gases, with an average dry film thickness of 60 mils (1.5 mm) and a minimum dry film thickness of 50

    mils (1.25 mm) at any point.

    F. Apply waterproofing to prepared wall terminations and vertical surfaces to heights indicated according to

    manufacturer’s recommendations and details.

G. Lay 3’ wide, polyester on and into the base coat of the membrane overlapping it 3’ (a light tack coat of ECOLINE-R or

    ECOLINE-S may be used around the edges of the polyester to temporarily hold it in place).

    H. Apply a second spray coat of ECOLINE-S or three 27-mil (wet) coats of ECOLINE-R to obtain a composite reinforced

    membrane with average dry film thickness of 120 mils and a nominal thickness of 100 mils.

I. Verify film thickness of waterproofing every 100 sq./ft. (9.3 sq./m).

     3.6 PROTECTION COURSE/ROOT BARRIER INSTALLATION

    A. Install ECOSHIELD-E15 protection course with overlapped seams over nominally cured membrane no later than

    recommended by manufacturer and before starting subsequent construction operations.

    3.7 INSULATION INSTALLATION

    A. Place insulation board meeting project requirements for R value compression strength and water absorption over

    protection course/root barrier with edges tightly abutted.

    3.8 DRAINAGE PANEL INSTALLATION

    A. Place and secure drainage panels to substrate according to manufacturer’s 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.

    3.9 FIELD QUALITY CONTROL

    A. 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.

    B. 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.

    C. Water test may be performed after installation of ECOLINE-S reinforced membrane and prior to the placement of the

    ECOSHIELD-E15 protection course. Perform test by ponding water at a minimum depth of 2-inches for a period of 48-

    hours.

    3.10 CURING, PROTECTING, AND CLEANING

    A. 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

    temperatures and/or high humidity, the full adhesion of the membrane may be delayed. The length of the delay is

    subject to the membrane and severity of those conditions.

    B. Take care to prevent contamination and damage during application stages, curing and subsequent construction.

    C. Clean spillage and soiling from adjacent construction using cleaning agents and procedures recommended by

    manufacturer of affected construction.
