LONG FORM SPECIFICATION
PART I GENERAL
1.01 SUMMARY
A. This specification serves as a guideline and shall be adapted to suit the needs of each
individual project by the architect. It is prepared in accordance with the CSI three-part
section format and shall be included as a separate section under DIVISION 7 - Thermal
and Moisture Protection. Improvements and other changes to the contents shall be
made only with the written approval of the architect.
1.02 RELATED SECTIONS (Note to Specifier:Edit to project requirements)
A. DIVISION 2 - Sitework [Section 02500/02870] - Paving/Site Furnishings as supplied by
American Hydrotech, Inc. See Division 7 for specific details.
B. DIVISION 3 - Concrete [Section 03300] -Roof Deck Surface/Substrate
The coordination of this section is necessary to facilitate the successful installation of the
waterproofing membrane.
Cast in Place Concrete/Composite Deck
1. Strength/density: minimum 2,500 psi (17,235 kPa) compressive strength
minimum 115 pcf(1842 kg/m3) density
2. Finish: Wood-float or wood-troweled equivalent finish. Steel
troweled finish is not desirable.
3. Concrete Hydration(Cure):
a. Method of Cure: Water cure, wet coverings, paper sheets, plastic sheets or
approved liquid curing compound(sodium silicate preferred).
b. Duration of Cure/Dry:
i. Structural Weight Concrete: recommend 28 days, minimum 14
days,prior to application of the membrane.
ii. Lightweight Structural Concrete: recommend 60 days, minimum
28 days, prior to application of membrane. Venting of the deck
from the underside is recommended to facilitate drying.
iii. The above minimum cure/dry times are recommended based upon
basic concrete fundamentals and experience. Depending on
conditions (i.e., ambient temperature, humidity) the concrete may
be dry enough to receive application of the membrane in less than
the 14 day minimum recommendation. Consult Hydrotech for
specifics when less than the minimum is desired.

complete coverage.
a. Laps and seams of Hydroflex 10 and 30 and Hydrocap 90FR protection
sheet shall be installed dry or sealed with membrane.
b. Laps and seams of Hydrocap 160FR protection sheet shall be sealed with
membrane or propane torch.
3. Hydroflex 10 and 30 and Hydrocap 90FR separator sheet/protection courses shall
be covered by insulation, fabric and ballast as soon as possible, within 30 days of
membrane installation.
4. Hydroflex 10 shall not be installed when Hydrodrain 300 is specified. Hydrodrain
1000, 400, 420 or 700 are appropriate directly over Hydroflex 10.
3.05 MEMBRANE INTEGRITY TEST
A. The roof area or portions thereof shall be leak tested by means of electronic testing or by
ponding water at a minimum depth of 2" (50.8 mm) for a period of 48 hours to check the
integrity of the membrane installation.
1. VERIFY that the structure can support the dead load weight of a watertest before
testing.
2. If leaks should occur, the water shall be drained completely and the membrane
installation repaired.
B. In the event of excessive damage to the membrane assembly, electronic breach detection
testing shall be required prior to the placement of subsequent overburden materials.

3.06 DRAINAGE COURSE / INSULATION / FILTER FABRIC / BALLAST
PLACEMENT
A. General
