    For example, a 4" pipe, with 1" of thermal insulation makes a 6" penetrant (1" pipe covering on each side of the pipe), plus two pipe sizes = an 8" sleeve, creating a 1" annulus. In case of insulated piping, the size of the insulation must be taken into account for the intended firestop certification listing .

    Once excavated, the walls are then power washed and allowed to dry. The dry walls are sealed with a waterproofing membrane, [3] and new drainage tiles (weeping tiles) are placed at the side of the footing.

    The first heat-shrinkable sleeves were introduced [when?] as polyethylene pipeline coatings started to replace bituminous or tape coatings in the oil and gas industry. At the time, the processing for polyethylene to make the sleeve backing was new technology and the adhesives used in sleeves were much the same as those used on pipeline coating.

    The down pipe can terminate in a shoe and discharge directly onto the surface, but using modern construction techniques would be connected through an inspection chamber to a drain that led to a surface water drain or soakaway. Alternatively it would connect via a storm drain with 50 mm water seal to a combined drain. [19]
