Forty feet of rammed earth
A church in Stateburg, South Carolina, has stood on walls of tamped earth since 1852. What it shows about how earth walls age, and what eventually threatened it.
Rammed earth sounds like a new idea from the sustainable-building shelf. In South Carolina it has been in use for two centuries.
What pisé is
The South Carolina Encyclopedia describes pisé de terre as clay poured into wooden molds and tamped solid, then coated with stucco. Builders raise the wall one layer at a time, move the forms up, and repeat. The result is a dense, heavy wall that is strong in compression.
S. W. Johnson’s Rural Economy, published in 1806, introduced the method to American readers. Dr. William W. Anderson, who settled in Stateburg in 1810, used it to rebuild the wings of the Borough House at his Hill Crest Plantation in 1821, along with several outbuildings. Together they make up what the encyclopedia calls the largest complex of pisé buildings in the United States.
The church
In 1850 Anderson persuaded Stateburg’s Episcopal congregation to build its new church the same way. The Church of the Holy Cross, designed by the Charleston architect Edward C. Jones, was completed in 1852. Its yellow rammed-earth walls rise about 40 feet, covered in stucco, with buttresses along the corners and long sides of its cross-shaped plan. Inside, the walls are painted gray to resemble stone. It was designated a National Historic Landmark in 1973.
How it aged
The earth held. What nearly failed was everything around it. By the 2000s the church had extensive termite damage, and an 18-month, $2.3 million restoration was completed in January 2010.
That is the usual story with earth walls. They tolerate load and age well, but they depend on the timber, roofs and finishes that keep them dry, and those parts need maintenance.
If you want to build with it
Rammed earth is labelled case by case in the Atlas. In most US jurisdictions it needs an engineer’s design and soil testing. Its insulating value is low, so in cold climates it is usually paired with insulation. And the old rule still applies: give it a good hat and good boots, meaning a roof that sheds water clear of the wall and a base that keeps ground water out.
