... In the mid to late 1990s, the exterior insulation and finishing systems (EIFS) industry introduced drainage into its wall systems, aimed at increasing the water management of those systems. Along with this introduction came the development of test methods for drainage efficiency...

... of various types of water-resistant barrier materials will also be performed. Comparisons of the results are explored along with examples of actual in-service installations. stucco portland cement plaster water-resistive barrier water-resistant barrier drainage polymeric Grade D building paper...

... The Maine Department of Transportation (DOT) in conjunction with the University of Maine and the U.S. Army Cold Regions Research Laboratory evaluated the use of a special geocomposite drainage net as a drainage layer and capillary barrier (to mitigate frost heave) on a section of road plagued...

... Good highway drainage has been recognized for many centuries. The theoretical concepts are simple and the technology applicable to highways built today (1999) is widely available in the technical literature. It is widely understood that efficient drainage is essential to good highway performance...

... be performed more efficiently than sieving methods, and provides an accurate estimate of the permeability of the geotextile. bubble point clogging drainage filter geotextile permeability pore sizes pore size distribution retention Gregory R. Fischer, x Robert D. Holtz, 2 and Barry R...

.... Membrane/waterproofing continuity across joints and joint maintenance are of particular concern. An estimate of the joint movement is necessary to select a joint seal. Adequate drainage away from the joints remains the most important design consideration expansion joints joint seals waterproofing...

... the first 30 seconds, followed by a slower, dropwise drainage. The rheology of the fluids was measured using a Rheometrics RFS II variable strain rheometer in the dynamic mode. It was found that the weight of formulation remaining in the container after 1 minute's pour out correlated well with the viscous...

... is concentrated in the vicinity of joints and is precipitated by joint failure. Experience suggests that “the only good joint is no joint.” Yet joints are inevitable and their maintenance while still in serviceable condition is vital to the structure as well as to traffic. Drainage —More than 60% of the bridge...

... Plaza waterproofing is precarious because of the severe service conditions imposed on the system and the inaccessibility of the waterproofing membrane for repairs. Most systems are covered by a wearing surface that often impedes the drainage of water at the membrane level. The “buried” position...

..., and the recommended use of geotextiles for drainage applications as defined by the New York State Department of Transportation (NYS DOT) and the California Department of Transportation (Caltrans). Caltrans approaches the use of geotextiles for drainage in the same manner as they approach aggregate filtration...

... Of the available functions that geosynthetic materials possess, their ability to conduct liquids in the plane of their structure is important in a wide class of drainage applications. The thicker geotextiles (usually needled nonwoven types) and a new generation of high drainage composite...

Richardson^ and David C. Wyant^ Geotextiles Construction Criteria REFERENCE: Richardson, G. N. and Wyant, D. C...

... The first part of this paper presents a review of existing design methods for selected geotextile applications such as filtration, drainage, and unpaved roads. The discussion shows that geotextile applications can be designed using rational methods and that most of these methods are similar...

... on the external side of walls below grade level, the merits and performance criteria of this location were indicated and experimental work was done to quantify them, in particular, the insulation and drainage function. As a result, a draft specification for a product designed to these service standards...

... because the natural forces acting to remove moisture are small. Some moisture may be drained from wet roofs, but because the slope is small or nonexistent and absorptive forces tend to retain moisture it is not usually an effective method. If the retentive forces can be overcome, however, drainage rates...

... To provide combined moisture and thermal protection for basements, high-density glass fiberboard was used on the exterior of two prototype basements. This insulation-drainage layer can easily be adapted to current construction procedures and the cost is not excessively high. Performance...

... are discussed: drainage characteristics of the material and water retention after the drainage process, thermal resisitance, compressive strength, and elastic and irreversible deformations. All these properties are affected by the aging process of the material. Effects of various aging conditions simulated...
