rammed-earth-footings

Batter boards are being leveled and placed for the footings. Wide footings can support the heavy walls but also act to give seismic stability and make a bond beam unnecessary.

Steel is in place and the footings are ready for concrete.

rammed-earth-pillars-layers

These are some of the nicest rammed earth pillars ever! A big statement yes, but true. The layering and texture of these pillars is fabulous, the picture doesn’t fully capture the feeling in real life.

The rammed earth is complete! It was an epic journey and very rewarding.

Hart House – Building the walls

by

Building the Hart House walls was a challenging build. That November was the rainiest and windiest in 50 years and it rained almost every day but we persevered and are very proud of the results. Josh and Heidi went bold with red walls and it was a fabulous result. The exterior walls of this house are 2′ thick which is a standard width for exterior walls.

A good view of an insulated rammed earth wall in the making.  We use a rigid insulation that can withstand the forces of compaction.

rammed-earth-forms

The rammed earth forms we use are an efficient and flexible system of forming plywood, pipe clamps, form aligners and dimensional lumber. The wood can be used on other parts of  the building after the walls are done.

rammed-earth-forms-curved

Making the forms for the curved rammed earth walls. The forms are made in 4 pieces, 2 of which are very heavy, they are made with 3 laminated sheets of plywood that have been glued and screwed extensively with vertical 2×6’s.
