This sets a whole building standard of 125 litres per person per day for domestic buildings. This comprises internal water use of 120 litres per person per day, and in that respect is in line with Code Levels 1 and 2, plus an allowance of 5 litres per person per day for outdoor water use.
Deck Mud is a mixture of washed, graded sand and Portland cement that conforms to ASTM C 144. 1  Can be used to float over metal lath, concrete (with proper preparation) or approved crack/waterproof membranes.  Suitable underlayment mortar for substrate preparation or leveling floors and countertops.
Today I put down the second layer of deck mud (the first layer, the pre-slope, goes under the liner) onto the shower floor. This layer is constructed of a type of mortar that is called âdry-packâ mortar, or deck mud. There seems to be alot of different opinions on just what this should consist of, compounded by the fact that nobody seems to sell a pre-mixed deck mud product. It also seems that there are alot of different things that will work, and they really just vary in how easy they are to get down.
