Concrete Moisture Test Using Plastic Sheet Method
So it is suitable for the case where the application of coatings for concrete surface is planned.
Concrete moisture test using plastic sheet method. This means no numbers or data just simple observation or eyeballing of the test location and testing materials for signs of excessive moisture. Some methods of concrete moisture testing use a simple qualitative approach. 1 1 this test method is used to indicate the presence of capillary moisture in concrete. Plastic sheet test astm d 4263 plastic sheet testing method used to indicate the presence of moisture in concrete.
