Concrete Driveway Replacement Calgary

Spalling Concrete Driveway
  • High Water/Cement ratio. Subcontractors and inexperienced finishers will add too much water to the mix upon arrival at site to make their jobs easier. This leads to plastic shrinkage cracking and overall strength loss.
  • Inexperienced finishing procedures. Overworking concrete that has visible surface bleed water will change the chemical makeup of the slab surface, reducing strength. Or the slab will be getting too hard for the experience of the crew and they will use water on it to ‘save’ the job, same result.
  • Lack of/low air entrainment. Air entrainment is the intentional creation of tiny air bubbles in concrete. It’s done by adding a surfactant admixture to the ready-mix at the batch plant. This allows freezing moisture present in the slab a place to expand. Incorrect mix design, zero testing, over mixing, and poor attention to finishing all contribute to an incorrect air entrainment percentage (ideal ~5%).
  • Curing concrete is overlooked by many companies and homeowners. Concrete must be kept moist or covered for the first week to ensure your investment stands the test of time.
