If you’re planning a concrete project for a warm season, the hot temperatures can pose some unique challenges. The temperature of the air, the temperature of the concrete and the level of humidity are all concerns. Fortunately, the right DIY concrete hacks in Santa Rosa, CA can help. If your next concrete pour will take place in hot conditions, use the following guide to get the best results.

Potential problems

Hot weather can cause a variety of issues when pouring concrete. Keep the following potential problems in mind as you plan your project.

  • Finishing difficulties
  • Cold joints
  • Reduced durability and strength
  • Increased drying shrinkage
  • Increase risk for cracks
  • Reduced compression strength

Potential solutions

If you plan to pour concrete in temperatures above 77°F, use the following DIY concrete hacks in Santa Rosa, CA to prevent problems:

  • Buddy up: Pouring concrete in hot weather isn’t a solo sport. Be sure you have enough people on hand to manage the job properly.
  • Avoid peak times: If the concrete has to be poured on a hot day, schedule the project for cooler times of the day. Avoid pouring during peak times for hot temperatures.
  • Use smaller intervals: As you space control joints, place them at smaller intervals than you would if pouring concrete in cold weather.
  • Shade it: To reduce the effects of the hot conditions, use shades and windbreaks. For indoor concrete, schedule the pouring after walls and roofs have been constructed.
  • Hydrate: It’s important to maintain appropriate evaporation levels as the concrete cures, so keep an evaporation retardant on hand in case the high temperatures cause rapid evaporation.
  • Keep it cool: To cool the concrete, use ice as part of your water mix.
  • Reduce mixing time: After you add the water to the mix, reduce the mixing time.
  • Protect equipment: In addition to shading the work area, be sure to keep concrete mixes and all equipment that will be used for the project in the shade until they are needed.
  • Dampen: For slabs or walls, dampen the side forms with cool water. If you’re pouring concrete for a slab, dampen the sub-grade before you pour the mix.
  • Cure appropriately: Keep weather conditions in mind as you schedule curing. Use the correct method and time allotment to allow the concrete to set appropriately.
  • Contact professionals: If you have any questions during this process, don’t hesitate to contact concrete professionals for additional tips. These experts have the knowledge and experience to provide helpful advice and assistance to make your next concrete project a success.
