Inquire about the types of paver bases they typically recommend and install, such as compacted aggregate or sand-cement mixtures.

For paving slabs in St. Paul's climate, the best concrete mix typically includes a higher cement content and air-entraining admixtures. This design enhances resistance to freeze-thaw cycles and de-icing salts, common stressors in our region. The aggregate should be well-graded and clean, ensuring good workability and strength. Proper curing is also critical; methods like wet curing or the use of curing compounds help the concrete reach its full potential strength and durability. Consulting with independent service providers ensures the correct mix proportions are used for optimal performance in Minnesota's weather.
