Concrete Materials: What We Specify and Why
Concrete is a mixture of Portland cement, aggregate, and water — but the proportions, additives, and delivery conditions make all the difference.
Minimum for vehicle traffic. Higher PSI provides freeze-thaw resistance and longer service life.
Adequate for foot traffic. Lower cement content reduces cost on non-structural flatwork.
Polypropylene fibers distributed throughout the mix reduce plastic shrinkage cracking during the cure phase.
Provides tensile strength that concrete alone lacks. Epoxy coating prevents corrosion in coastal Bay Area conditions.
We explain every material choice in our proposals. You know what's going into your home and why before any work starts.
