Waterproofing materials that run vertically up from a foundation wall often terminate
in reglets above-grade (Fig. 10.25). Below-grade waterproofing materials, changing to
dampproofing systems above-grade, use reglets for transitions between these two systems.
Reglets are formed in substrates during the placement of concrete by using blockouts.
They are also formed by sawing concrete, masonry, or wood substrates to form a reglet
recess (Fig. 10.26). After a reglet is in place, it is inspected for cracking, honeycomb, or
other problems that can cause leakage.
With certain flashing systems, surface-mounted reglets, mechanically fastened to sub-
strates, are used. These are often used in remedial waterproofing repairs or roofing instal-
lations where existing reglets are not functioning or do not exist. Reglets are not recesses
