"A water test is conducted in one of two ways. (2 bullets.)"311. Introduction. "The NRCA Waterproofing Manual defines waterproofing and dampproofing as follows:(2 bullets).""Waterproofing systems can be divided into two primary categories: positive side and negative side,which are defined as follows (2 bullets)."322.1 Waterproofing. "Waterproofing is defined as the treatment of a surface or structure to prevent thepassage of water under hydrostatic pressure. Water exerts a pressure of 62.4 pounds per square foot perfoot (1,000 kg per square meter per meter) of depth because water weights 62.4 pounds per cubic foot(Ib/ft 3 ) (1,000 kg per square meter per meter)."332.2 Drainage. "A drainage system is a system of perimeter and/or underslab drains used to relieve thehydrostatic pressure in the earth surrounding a below-grade structure."33-342.2.1 Geocomposites (Drainage mat). "Hydrostatic pressure can be relieved from perimeter wallsbelow grade by using a coarse aggregate backfill or a prefabricated drainage product known as a"geocomposite."1 Exam Prep – NRCA Waterproofing Manual - 20052

Page #Highlight"Deck drains that have the ability to receive water at the top surface of the overburden (e.g., concrete slab,pavers) and at the membrane level are called bi-level drains or multi-level drains. NRCA recommends theuse of bi-level drains where drainage occurs at two levels."352.3.2 Walls Below Grade/Vertical Surfaces. -NRCA recommends building foundation walls belowgrade surrounding habitable spaces receive some form or waterproofing and drainage treatment.""Waterproofing can be applied to either the positive (exterior) or negative (interior) side of below-gradecast-in-place concrete foundation walls."37-382.4 Suggested List of Waterproofing Materials. Note and highlight each of the suggested waterproofingmaterials.402.6.1 Asphalt Built-up Membrane. "Asphalt built-up waterproofing membranes are composed ofalternating layers of asphalt reinforcing ply sheets. The most common type of reinforcing ply sheet is anasphalt-impregnated glass fiber matt. The number of plies of membrane depends on the hydrostaticpressure head that needs to be resisted. The relationship between hydrostatic pressure and the minimumnumber of plies recommended is as follows: ." (Note and highlight the Hydrostatic Pressure Head, Feetof Water for Asphalt chart.)40-412.6.2 Coal-tar Built-up Membrane. "Coal-tar built-up waterproofing membranes are composed ofalternating layers of coal tar and reinforcing ply sheets.
