Large Enough to Have What You Need, Small Enough to Speak DIY
DIY At Paragon Performance Concrete we’re proud of our crew and the service and products we supply to both professional contractors and homeowners alike. Unlike some large multi-store concrete suppliers, Paragon has just 2 locations. With one in Waterford and one in Utica we’re just big enough to buy in bulk and pass the savings on to you, but small enough to talk DIY.
The calculator to the right is designed to assist you in determining the amount of concrete you’ll need to order.
The calculator will provide you with an approximate range of accuracy. Cubic yards are rounded up in 1 yard increments. Variations in the grade on the job site are not reflected in calculations. Check with the dispatcher ( 248-623-0100 ) if you would like a more precise figure on actual yardage needed.
PLEASE: Order the right amount of concrete. Be sure to make a 10% allowance for uneven sub-grade, spillage, etc. and round up to the closest 1/2 yard. Let us know what you are pouring (flatwork, wall, slab on grade, etc.) If you think a job may need more concrete, tell us when placing your order as it is always easier to cancel a truck than to add more.
NOTE: This calculator is to be used as an estimating tool ONLY. Paragon is not responsible for any discrepancies in material based on calculations made with this application.
Finishing while bleed water is still present on the surface. This creates weak bonds and “dusting”.
The presence of high amounts of carbon dioxide due to inadequate ventilation. Pertains to indoor work.
Inadequate or insufficient protection of the surface from rainwater, snow or wind.
Don’t finish concrete with bleed water present on the surface.
If excessive bleeding occurs, remove it by dragging a hose, rope or squeegee across the surface. Do NOT sprinkle dry cement on the surface to absorb the excess water. That will simply cause more dusting to occur.
Use a moderate slump (5″), unless the mix design can handle a higher one without bleeding. This is especially important in cooler weather when setting time is lengthened creating greater opportunity for bleeding to occur.
Avoid direct placement of concrete on polyethylene or non-absorptive sub-grades, place 1 to 2 inches of sand between. For absorbent sub-grades, dampen the surface before placement.
Protect concrete from the environment while curing by sealing or covering.
In cold weather conditions, use warm concrete and accelerator to reduce setting time. Modifying mix proportions and using air-entrained concrete can also reduce bleeding. For more information, please talk to the dispatcher about these options when ordering your concrete.

Flaking & Peeling = "Scaling"
Signs: Scaling usually starts in small patches that may merge and eventually expose large areas.
No or an insufficient amount of air entrainment in the concrete. Air entrainment is an essential component of exterior concrete because small air “bubbles” provide room for water to expand into when temperatures hit freezing and below.
Concrete exposed to freezing and thawing in the presence of moisture and/or de-icing salts when it has been finished with bleed water on surface. The bleed water causes a high water-cement ratio and a low strength surface.
Over finished – surfaces that have been “worked” in the finishing stage too long or too aggressively by inexperienced crews are often predisposed to scaling.
Immature concrete exposed to calcium or sodium chloride de-icing salts, or other salts that may cause a chemical attack on the surface of the concrete can lead to scaling.
Use low slump, air-entrained concrete. Notify Paragon’s Materials dispatcher when ordering that you are pouring exterior concrete and need air-entrained concrete.
Avoid the use of de-icing salts the first winter, preferably longer.
Assure proper curing by protecting concrete from the elements.
Never finish with excess water on the surface.
Avoid overworking the surface, a broom finish is recommended.
Multiple Fine Cracks on the Surface = "Crazing"
Symptoms: A significant amounts of fine cracks on the surface of the concrete, often referred to as pattern or map cracking. These fine cracks do not affect the structural integrity of the concrete, but can be aesthetically displeasing.
Weather Matters (or at least compensating for it) Rapid drying of the concrete due to high temperatures, low humidity and/or drying winds.
The overuse of placing tools which can bring excess mortar to the top.
Premature finishing with a float and trowel brings excess moisture and paste to the surface. A rapid loss of this moisture could cause crazing.
Use of dry cement to absorb excess water on surface. If you ever see a crew member sprinkling dry powder on a just poured jobsite — you’ll have problems down the line.
Hire the right crew. Paragon can refer you – 248-623-0100 .
Use low slump, air-entrained concrete.
Maintain the water-cement ratio at the surface by using evaporation retardants after screeding (leveling with a straight edge).
Use fog spray or cover with wet burlap or canvas as soon as possible after strike off and darbying and maintain until concrete is nearly ready for finish.
Do not overwork the surface pace.
Begin curing immediately, and when possible continue mist curing to lower temperature by evaporation.
Do not begin finishing with excess water on surface.
