Abstract: A novel mortar mix and mortar formed therewith. The mortar contains sand, lime, cement and microtubes in a mixture thereof. The microtubes assist in wicking moisture directly through a wet mortar compound formed by adding water to the mortar mix.

It also allows water to pass through the mortar in a similar manner as the masonry, creating two in-sync cycles, rather then two disparate cycles for water flow. In various embodiments, the microtubes could be composed of cellulose, fabricated polymer or graphite.
