Performance
Assessments of the performance BLOK-FLASH® to handle moisture penetration and to develop bond capacity.
Testing Date:           October 23,1998
Test Performed by: Soil and Materials Engineers, Inc. 734-454-9900
Test Method: ASTM E 514-90 (1996)Water Penetration of Masonry*

Water Penetration Using BLOK-FLASH®:
TIME/HRS                                                   4:30
BASE EXTERIOR                                       NONE
BASE INTERIOR                                        NONE
CORES BELOW BLOK-FLASH®                NONE
BLOK-FLASH® WEEPS                             3.775 LITERS
*Used in conjunction with an Integral Water Repellent System

Conclusion:
The sample wall absorbed minimal moisture (375 ml/12 sq.ft.) at the exterior face (chamber side) with the penetrating free water collected by the BLOK-FLASH® system and weeped per design. No visual indications of water penetration or by-passing of the BLOK-FLASH® system were observed during the testing.
