Trinity Lightweight's expanded shale and clay lightweight aggregate can reduce the density of compacted geotechnical fills by up to one-half. This advantage, coupled with its predictable high internal friction angle, can also reduce lateral forces by more than one-half.
Lightweight aggregate has been effectively used to solve numerous geotechnical engineering problems and to convert unstable soft soil into usable land. Lightweight fill also provides permanent non-degradable insulation around water lines and steam lines, and other thermally sensitive elements. Where thermal stability is required, lightweight aggregate provides significantly greater thermal insulation when compared to ordinary soil, sand or gravel fill. This inert, durable, stable, free-draining and environmentally friendly lightweight aggregate is extremely easy to handle and provides economical long term solutions for geotechnical challenges Trinity Lightweight aggregate is a reliable and economical geotechnical solution.
Lightweight aggregate from Trinity Lightweight is being used to protect and preserve part of a Birmingham, Alabama landmark. The Powell Avenue Steam Plant, built in 1895, is being redeveloped by Alabama Power to become a historic destination in the heart of 21st Century Birmingham.
More than four years after Trinity Lightweight expanded shale aggregate was installed on the west end embankment of the US 67 bridge over State Highway 174, the quiet performance of the product is allowing the heavy traffic on the bridge to roll on without incident.
In Texas and many other parts of the country, existing sanitary sewer interceptors are often not sized appropriately to withstand peak flow rates, and in some situations, can't even handle average daily flows.
Designers of Corridor X, a major interchange being built just north of Birmingham, Alabama, had an engineering challenge. New traffic lanes needed to go over the top of an existing concrete drainage system. The problem? The volume of fill material needed to build the area up to grade was enough to cause concerns about cracking the culvert.
Thanks to lightweight aggregate, a New Orleans home is back on stable ground after falling victim to coastal Louisiana’s age-old issue of land settlement. That has a distressed homeowner feeling much better after the landscape surrounding his property in the historic English Turn community began sinking a few years ago.
