Concrete Leveling questions, answered by experts

A floating slab is a single chunk of concrete that sits directly on flat soil, while a monolithic slab is a single piece of concrete that includes built-in footings that reach several feet below where the majority of the slab sits. Monolithic slabs provide more support, so they’re suitable for home construction, whereas floating slabs get minimal support from the soil directly below and are more common under sheds and detached garages.

No, cement cannot be used on its own except for rare circumstances, as it's only a binder to form other products, such as concrete or mortar. Follow the manufacturer's instructions to create a concrete or mortar mix. Concrete, for instance, needs cement, water, and aggregates such as sand and gravel. Using the right amount of water and water temperature is essential to ensure you have the right concrete slump and the mix spreads easily and cures well.

Yes, baking soda and vinegar can remove rust from concrete. Vinegar is acidic and can remove rust stains from concrete on its own. Adding baking soda may increase abrasiveness, which could help loosen some of the stain even more when scrubbing the stain. However, a stiff-bristled brush can do the same. 

Concrete log siding is not the same as fiber cement siding. Fiber cement siding is made from a mixture of cement and cellulose fibers, while GFRC is made from cement, glass fibers, and polymers. The materials are similar in their durability, longevity, and curb appeal, and the main difference is that concrete log siding is available in more styles that resemble traditional log siding. Fiber cement is also less expensive, with materials costing around half what you’d pay for concrete log siding.

Yes, you should seal your exposed aggregate concrete to keep it protected from the elements and reduce the risk of cracking and concrete spalling. You’ll need to invest in the cost of resealing your concrete about every three years to keep it in good condition. Unsealed exposed aggregate concrete is susceptible to water damage, stains, chips, cracks, and abrasion. Sealers are available in various finishes and levels of gloss. Outdoor exposed aggregate concrete should be sealed with a non-yellowing, UV-resistant sealer to preserve the look of the finish.
