The drain shall extend a minimum of 12 inches beyond the outside edge of the footing. The thickness shall be such that the bottom of the drain is not higher than the bottom of the base under the floor, and that the top of the drain is not less than 6 inches above the top of the footing Minimum Pier and Pier Footing Thickness. The minimum thickness for a pier is 8 inches. The minimum thickness for pier footings is 8 inches or 1-1/2 times the length of the footing projection from the pier, whichever is greater Code says an exterior footing drain is only required when the finished floor is below grade. Put another way, if the finished floor of the crawl space or basement or garage floor is above the..  The footings are constructed per the approved plans. (R403)  All loose soil, mud, or water is removed from the bottom of the footing. Debris, water and/or ice removed from spaces to be occupied by concrete. (R404.4.6 & ACI 318)  Steel reinforcement is properly placed and is the correct grade (40 or 60 are most common). (R404.1.2.3.7, & ACI 318-7.7.1 On its face, the location of a foundation perimeter drain seems like the simplest of details. The perforated drain line is run around the foundation next to the bottom of the footing. At least that's what many construction drawings show. But in some parts of the country, the drain is placed on top of the footing rather than next to it, and this discrepancy is at the root of Steven Knapp's dilemma

Foundation drain tile and sump pumps manage the moisture to keep basements and crawlspaces dry. Drain tile is either clay sections or perforated drain pipe; it conveys water away from the house or to a sump pit in the basement or crawl space, where a sump pump then pumps the water away from the foundation, preventing water pressure from. The rationale for not requiring secondary drainage is that if positive drainage is provided, that is adequate to drain the roof. Exception #1 of Section 1511.1 states existing roofs do not have to meet the requirements of the code if positive drainage is provided. The minimum slope the code allows is ¼ in./12 in Reinforcement and Drainage Considerations. Taking measures such as installing steel reinforcement in the footing and extending from the footing up into the wall material may increase the strength and effective lifespan of the brick wall. Solid masonry walls with poured concrete footings require that drainage requirements be taken into account

Bulk water must be drained from the lowest portions of the foundation (below the interior finish floor level): this is the function of the footing drain, which is in turn drained to daylight or to a sump pit and pumped out (see Figure 1). The drain or sump (Figure 2) keeps ground water levels below interior floor levels and also drains away any water that has been collected by the foundation. R401.3 Drainage.
