ASTM E 2128

Historical Version s – view previous versions of standard. Work Item s – proposed revisions of this standard.

It addresses the performance expectations and service history of a wall, the various components of a wall, and the interaction between these components and adjacent construction.

It is not intended as a construction quality control procedure, nor as a preconstruction qualification procedure.

It is intended for evaluating buildings that exhibit water leakage. It is the responsibility of the professional using this guide to determine the activities and sequence necessary to properly perform an appropriate leakage evaluation for a specific building.

The preliminary assessment may also indicate that the wall is s2128 the source of a leak even though it is perceived as such by the building occupant.

The presence of water might result from a roofing problem, a condensation problem, a plumbing problem, operable windows or doors left opened or unlatched or some other condition not directly related to water leakage through e21228 building wall and is outside the scope of this guide. The evaluation of causes may likewise be limited in scope, and the procedures recommended herein abridged according to the professional judgement of the evaluator. A statement stipulating the limits of the investigation should be included in the report.


The objective is to be as comprehensive as possible within a defined scope of work.

The methodology in this guide is intended to address intrinsic leakage behavior properties of a wall system, leading to conclusions that generally apply to similar locations on the building. Since every possible location is not included in an evaluation program, it is probable that every leak source will not be identified. Leakage sources that are localized and unique may remain r2128 may require additional localized evaluation effort.

ASTM E – 01a Standard Guide for Evaluating Water Leakage of Building Walls

The potential results and benefits of the evaluation program should not be over-represented. Reference is made to design features of a wall only for the purpose of identifying items of xstm for consideration in the evaluation process. It is not intended for use with structures designed asm retain water, such as pools and fountains. For this purpose, water penetration is considered leakage, and therefore problematic, if it exceeds the planned resistance or temporary retention and drainage capacity of the wall, is causing or is likely to cause premature deterioration of a building or its contents, or is adversely affecting the performance of other components.


A wall is considered a e228 including its exterior and interior finishes, fenestration, structural components, and components for maintaining the building interior environment. It is the responsibility of the investigator to establish the limitations of use, to anticipate and zstm of the destructive nature of some procedures, and to plan for patching and selective reconstruction as necessary.

Establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Awareness of safety and familiarity with safe procedures are particularly important for above-ground operations on the exterior of a building and destructive investigative procedures which typically are associated with the work described in this guide.
