- Insulating Concrete Liner
- LNG Spill Containment - Sulfate Resistant Concrete Liner
- Molten Sulfur Service - Precast Concrete Building Components
- Structural Foundation Components
- Precast Electrical Ductbank
- Precast Process Unit Decks (versus bargrate)
Composite Precast Concrete Trenches
Alfred Miller Contracting has developed a unique multi-stage casting process where the internal liner of trench is cast first utilizing a specialty high-performance material. Liner material is specifically selected and thicknesses designed based on service conditions. A structural concrete outer shell is cast creating a composite section. The precast unit is then delivered to the field ready to install.
Insulating Concrete Liner - Trenches are manufactured utilizing a unique insulating cellular concrete that weighs 60 pounds per cubic foot. It is used as an insulating liner for LNG spill containment trenches. It has been accepted by the Federal Energy Regulatory Commission (FERC).
Sulfate Resistant Concrete Liner - A composite precast concrete trench and expansion joint system for molten sulfur service utilizing a sulfate resistant liner.
Precast Process Structure Decks

Alfred Miller Contracting provides a waffle type precast floor panel that is used in Process Structure Decks. This replaces bar grating, secondary support steel, and lateral bracing. The cost is typically 40-50% of the cost of the steel, and only requires 20% as many field installation manhours.
Structural Foundation Components
Alfred Miller Contracting manufactures precast foundation beams, pads, retaining walls, and other structural components.
Precast Electrical Ductbank
Alfred Miller Contracting has developed a precast structural ductbank system that requires no field concrete placement. The system is based on 40 foot sections of ductbank made with red concrete that contains all the conduits ready to receive cabling. The field installer simply excavates a trench and places the ductbank component. Shoring and large excavations are eliminated, because no personnel are placed in the trench during installation.
Novel Precast Applications
Alfred Miller Contracting has a long history of developing precast solutions that reduce field manhours. We excel at developing the critical details that make new ideas successful.
