Additions , <br /> The TUFF-N-DRI Full-System Limited Warranty includes foundation additions only when the following ' <br /> criteria are met: <br /> 1. The addition must have a proper exterior drainage system that channels water to a functional <br /> sump or to drainage pipe properly sloped to a daylight exit. See Drainage Requirements ' <br /> listed below. <br /> 2. The addition walls must be block, parged block, poured concrete, or pre-cast concrete and must ' <br /> meet preparation requirements listed above. <br /> 3. The cold joint between the existing foundation wall and the new addition wall must be prepared ' <br /> with a urethane based cold liquid-applied waterproofing material, applied and fully cured per <br /> manufacturers instructions, to a minimum of four inches on both sides of the joint prior to the <br /> 60-mil application of TUFF-N-DRI Membrane. This cold joint area must also have a drainage/ � <br /> protection board applied over the urethane liquid membrane and TUFF-N-DRI Membrane. This <br /> cold joint area is not covered under the terms of the TUFF-N-DRI Full-System Limited Warranty, <br /> but if the proper preparations are taken, the area should not leak. ' <br /> Top of Wall Transitions ' <br /> In some building markets, it is common to see a few rows of block masonry on top of a poured wall, or <br /> a short poured wall on top of a block masonry wall. The cold joint between the two different foundation <br /> materials must be prepared by an application of a urethane based, cold liquid-applied waterproofing � <br /> material, applied and fully cured per manufacturers instructions, spanning the joint and extending <br /> a minimum of four inches above and below the joint, prior to the 60-mil application of TUFF-N-DRI <br /> Membrane.Although this cold joint transition area is not covered under the terms of the TUFF-N-DRI , <br /> Full-System Limited Warranty, if this procedure is followed, the area should not leak. <br /> If the entire wall is parged with one continuous smooth coating covering both the block and poured , <br /> sections without interruption, apply the TUFF-N-DRI Membrane following the normal procedure for parged <br /> walls. <br /> Brick Led es ' <br /> 9 <br /> The horizontal brick ledge area of a foundation wall is not covered under the terms of the TUFF-N-DRI � <br /> Full-System Limited Warranty. Brick ledge areas are not covered for the following reasons: <br /> 1. Brick ledges are almost always left exposed to ultraviolet rays for longer than 15 days. ' <br /> 2. The brick application process can puncture and/or scrape the TUFF-N-DRI Membrane. <br /> 3. Water that penetrates into the brick or stone below the sill plate may have no drainage exits, <br /> and may accumulate on the brick ledge. , <br /> Drainage Requirements <br /> In order to qualify for the 30-Year Limited Warranty, a proper drainage system must be installed. r <br /> TUFF-N-DRI requires a positive drainage system that is consistent with good construction practices and <br /> that meets local code requirements. An exterior drainage system consisting of a 3-inch minimum diameter ' <br /> perforated drainage pipe, with gravel covering the pipe and footing and extending at least one foot (12") <br /> up the face of the WARM-N-DRI or TUFF-N-DRI Barrier Board on the vertical wall is required. The drain <br /> tile must channel the water to either an operating sump pump or to a gravity (daylight) drain. DrainStar° , <br /> Foundation Strip Drain, installed so that it can drain the WARM-N-DRI BOARD, is also an approved <br /> exterior drainage system, where accepted by code. <br /> , <br />
