WATERPROOF MEMBRANE INTEGRITY SURVEY AND LEAK LOCATE AND MONITORING ARRAY

PART 1 - GENERAL

1.01 Summary

A. Section Includes:

1. Electric conductance leak detection scan of membrane areas indicated below, and as scheduled at the end of this section, to verify membrane water proof integrity.

SELECT PARAGRAPH a. AND/OR b. BELOW DEPENDENT ON PROJECT REQUIREMENTS. DELETE EITHER PARAGRAPH THAT IS NOT APPLICABLE.

a. New waterproof membrane including vertical surfaces and penetration seals [-all roof and deck areas] [-roof and deck areas as shown on Drawings].

b. Existing waterproof membrane including vertical surfaces and penetration seals [-all roof and deck areas] [-roof and deck areas as shown on Drawings].

2. Installation of permanent Monitoring Grid with associated Access Closure and related testing and measuring apparatus to facilitate membrane leak locations to within an area defined by the grid spacing. The leak locate function is performed at the grid access closure or by remote computer control using associated switching and measuring equipment without requiring access and testing on the surface of the covered roof.

1. Field Report.

2. Proposal for Maintenance Service as specified below.

1.03 Quality Assurance

A. Qualifications:

1. Survey Company Qualifications: Minimum three years experience in performing roof surveys, or as certified by Detec Systems to perform surveys as specified herein.

1.04 Delivery, Storage, and Handling: A. Reference Section 01 66 00-Product Storage and Handling Requirements.; B. Special Instructions: Protect electronic equipment and sensing and detection devices against potential damage from dust and moisture.

1.05 PROJECT/SITE Conditions

A. Environmental Requirements: Do not perform scan(s) when heavy rain is falling.

B. A hose connected to a water supply, and of sufficient length to reach all points on surfaces to be surveyed, shall be provided for surveyors use.

C. Existing Conditions:

1. Membranes to be scanned must be broom clean (except for follow-up surveys on vegetated waterproofing) and be free of overburden, construction materials, equipment and debris.

2. Vents, pipes, supports and similar membrane penetrating components must be made of non-conductive material or be electrically isolated by layers of material added to the penetrating component above the waterproof membrane.

3. The waterproof membrane must extend above all overburden to avoid unintended electrical paths to ground.

4. A suitable liquid applied or weather proof insulating material or a cap sheet may be applied to insulate exposed concrete. Metal flashings and other metal elements should be clear of overburden and soil to achieve the electrical insulation and avoid unintended grounds.

1.06 Warranty: A. Membrane Integrity Scan: The membrane integrity scan provides the integrity condition only at the time of the scan and gives no assurance of future condition. No warranty is expressed or implied.
