Overview
Preload designs and builds wire-wound prestressed concrete tanks for water storage, wastewater, LNG and related infrastructure worldwide. It uses high-strength steel wire embedded in concrete walls to place the structure under permanent compression, making tanks sturdier and less prone to cracking. It differentiates itself by pioneering prestressed concrete tank design since the 1930s and now offering a full suite of features like sliding base joints and seismic design, plus the ability to deliver both steel and concrete solutions through its Caldwell Tanks affiliation. Its goal is to provide durable, low-maintenance storage tanks and related infrastructure at scale to support safe water and energy storage globally.
