By Basit Awan<\/em><\/p>\n Moisture is one of the biggest problems for buildings as it can rot the structure and bring about mold\/other such issues. Most structures fail before their time because of moisture.<\/p>\n Most structures in North America are built as if they are separate from the environment. Under the misconception that if they wrap the building with plastic, it will completely block out the building from all the moisture of the outside world.<\/p>\n Unfortunately this misconception has led to the failure of many structures before their time because if a structure is tightly wrapped with plastic, it still takes in moisture but doesn\u2019t let it out that easy. When this happens, the moisture causes rot and damage.<\/p>\n In order for a structure to survive in the environment where moisture is the building block of life, the structure must be able to breathe moisture.<\/p>\n When a structure breathes moisture, it is able to take the moisture in and let it out. This is not only healthy for the building but it is also very healthy for the tenants residing in the building.<\/p>\n How does hempcrete regulate moisture?<\/strong><\/p>\n \u201cHemp shiv is a naturally vapour-permeable material, meaning that it allows water vapour to travel through it, thanks to its porous nature: it has a microscopic structure of tiny capillaries created by the cell walls, orientated in the direction of the plant\u2019s stem. This capillary structure accounts for the hemp shiv\u2019s hygroscopic behaviour \u2014 its ability to attract and hold moisture from the surrounding atmosphere, releasing it again in response to changes in the humidity of the environment.\u201d <\/em><\/p>\n \u201cThis vapour permeability may seem an alien concept to anyone who has worked with conventional synthetic building materials over the last 50 years or so, since \u2018advances\u2019 in material technologies have often centred on the production of building materials that were intended to form a vapour barrier, keeping moisture out of the building.\u201d<\/em><\/p>\n \u201cBevan and Woolley report that there are several anecdotal examples of test panels of hempcrete being cast and left out in the rain, without rendering, for periods of up to several years without any deterioration of the material, and in spray-testing by the BRE Group, hempcrete performed extremely well in resistance to water ingress\u201d<\/em><\/strong><\/p>\n<\/blockquote>\n READ MORE<\/a><\/p>\n (To find out more about advertising CLICK HERE<\/a>).<\/p>\n Help Wanted: <\/strong><\/p>\n Texas: Careers in Hemp Building, a modern take on the historic craftsman.
