By Jim Mimiaga Need to build a quality home fast and on the cheap? Check out an alternative building technique that combines newspaper or clay with cement to form sturdy bricks and walls that stand up to strength tests. Using either the "papercrete" or "fibred-adobe" process, a modest 1,000 square-foot home could be built in only a few months with $2,000 in materials, according to Philip Mirkin, an architect from Egnar who teaches seminars on the process. Mirkin, 40, fell in love with papercrete because of its creative possibilities and affordability. "It is easy to do and dirt cheap," says Mirkin. "Ten-year-old kids are strong enough to build a papercrete house — it’s that simple." In contrast, wood-frame homes typically cost between $20 and $30 per square foot, as do straw-bale homes. Both types of construction also require ample expertise. The recipe for making papercrete bricks calls for one part clay or newspaper (or both), one part water and one part Portland cement. Combine; pour pulp into desired forms; allow to dry. The resulting papercrete or fibredobe brick is so strong, it exceeds the tensile strength of cement and has proven load-bearing capacity. "The paper fibers lock in with the clay or cement and create a matrix of interwoven material that’s lightweight and very strong," Mirkin said, adding that the building material will hold up for 150 years. To mix large quantities, Mirkin uses an innovative contraption. He fitted a truck bed with a large container that, at the bottom, has a lawnmower blade connected to the truck’s drive train. Once the ingredients are added to the 200-gallon mixer, the truck is driven around a bit and, presto! — a thick mud suitable for construction is formed. Once the bricks or shaped forms have dried out, which takes between one and three weeks, they are ready to be stacked to form walls, arches, doorways and roofs. The same mud is used for mortar and as a plaster after the wall is up. The structure can then be sealed with linseed oil or paint. The result is an adobe-style house, but without the high cost. Advocates say papercrete has advantages over straw-bale construction because the papercrete walls are load-bearing, more versatile and less labor-intensive. Other attributes are that it is fire-proof, does not use toxic materials, encourages conservation and recycling, saves trees and has a high insulation value. Because it is so light, building with papercrete does not require a foundation. Wet weather does not harm the material, and roofs can hold up to 20 feet of snow. The method has been around since the 1920s but is just now gaining significant acceptance. Mirkin expects papercrete to become as mainstream as strawbale construction, and says the federal government is about to approve it as code-worthy. The town of Crestone, Colo. has adopted the technique as an acceptable alternative that meets building codes. There are some 20 papercrete homes in Crestone. Curved walls and dome ceilings are easily built using the material, Mirkin said. He is experimenting with red willow woven into the ceiling as a natural highlight. And, amazingly, a wall built with this material has such strength that windows can be cut in by using a chainsaw, Mirkin explained. "It is very free-form, so say you want a window shaped as a half-moon, then get out the chain or jig-saw and cut away," he said. "It’s almost impossible to screw up using this material." Mirkin is offering several seminars this winter. One is today from 11 a.m. to 4:30 p.m. at Mirkin’s place near Egnar. A workshop follows on Sunday, Dec. 2, beginning at 11:30 a.m. Cost is $35 for the seminar and $20 for the workshop. Two others will be held in Durango on Dec. 8 and 9. That one costs $50 total. Call 677-3600 to register and for directions. Space is limited. Mirkin can also be reached via e-mail at philipmirkin@ hotmail.com |
