Abstract
Extensible shells and related methods for constructing a support pier are disclosed. A shell can define an interior for holding granular construction material and define an opening for receiving the granular construction material into the interior. The shell can be flexible such that the shell expands when granular construction material is compacted in the interior of the shell. A method may include positioning the shell in the ground and filling at least a portion of the interior of the shell with the granular construction material. The granular construction material may be compacted in the interior of the shell to form a support pier.
