HTI Systems, LLC - Precast Concrete Products, Specialty Pumps & Process Systems

Precast vs. Cast in Place

The HTI tank design is generally considered to be superior to cast-in-place concrete tanks by engineers familiar with our tank system for a number of reasons, including its greater strength factors, its aversion to developing fracture cracks which could result in hard-to-locate cracks in a cast-in-place tank, and a longer useful life. This is largely (but not exclusively) because our design and construction has strategically-placed seams as shown in Fig.1 which have an industry-approved sealer provided by a member of the Chevron Family of Companies. We have NEVER had a system or structural problem with this type of tank.

We believe it is important to articulate that the design and the sealant used in the HTI tank is of such an environmental quality that regulatory agencies allow the HTI tank to be built for potable water storage, as well as biosolids storage and carries up to a 20 year warranty by the sealant manufacturer.

The photo in Fig. 2 is a cast-in-place tank that was NEW when this photo was taken, and hadn't even been put into service yet, and yet shows numerous cracks in its structure. This illustrates very clearly what a cast-in-place tank can do (and frequently does do) and what our precast tank WON'T do.

Besides the superiority of the precast storage tank, the HTI Tank System also takes significantly less time to complete, from a construction process, than do other comparable construction systems.

Currently, if engineers want competitive prices for concrete storage tanks, they generally specify either the HTI precast tank exclusively alone, or specify it (HTI as the only named supplier) along with a specific general cast-in-place design generated by the consultant. This way, if the precast tank system is utilized, the general contractor will not be managing a project that deals with a substitute and substandard precast system.

If you want uncontrolled cracks, the potential for leakage and are willing to pay more money for a product that may not last as long, then you should probably build a cast-in-place tank.
