Polywater® InstaGrout Sealant for transformer pad openings is designed to flow as a liquid, cure into a strong polymer matrix, and seal around complex stub-ups. It naturally expands to a thickness of 3 to 4 inches. Kit coverage is calculated using a 3-inch fill depth. Usage amounts can be estimated with the help of the InstaGrout Quantity Determination Instructions. The basic idea is to carefully measure the area to be sealed by multiplying the width (in feet) by the length (in feet) of the structure, without subtracting for conduits or other stub-ups. This measurement is used to estimate the minimum quantity required, and then is rounded up to determine the number of kits required. Example: A pull box measuring 15 inches (1.25 feet) by 36 inches (3 feet) = 3.75 square feet. The seal requires one PMT-3 kit and one PMT-1 kit (4 sq ft of coverage at 3-inch depth). Excess sealant can be used to fill any holes or gaps. Alternatively, fill volume can be calculated by multiplying width, length and depth in feet. The instructions include a table to help calculate kit requirements. Factors that increase quantity requirements include:
