We work with contractors and owners to provide information for plastic shrinkage cracking. We provide detailed information on rate of evaporation and how and when to take precautions to avoid early moisture loss in fresh concrete pours. How to determine early moisture loss. Avoiding early moisture loss in concrete is critical early loss of hydration water may reduce surface PSI by up to one/half.

Mike Murray & Luke Snell were both presenters at the Mongolian Concrete Conference June 5 2015


In Chemistry the PH scale measures how acidic or  alkaline concrete is. High on the PH scale is about 11 for concrete. This is important as lower PH levels will lower the concretes ability to withstand effects of chemicals such as de-icing salts. We understand and work with clients to solve this and early carbonation issues. When reviewing mix designs we carefully review admixtures and air content. Our knowledge of mixes can help achieve the needed durability requirements.

ACI Flatwork Training

More projects and owners require training and certification for concrete finishers. ACI offers one of the best. Mike has been involved with ACI 640 Flatwork certification for over 15 years he himself has held the Flatwork finisher certification for over 20 years. Our review workshop covers all aspects for the examination

  1. Basic concrete technology
  2. Concrete materials & mix proportions
  3. Concrete control tests
  4. Proper use of finishing tools
  5. Placing , consolidation & finishing
  6. Edging , jointing , curing & protection

Training may be done in-house and additional fees will apply for ACI EXAM and test
