Concrete Leveling questions, answered by experts

One of the best base materials for a floating deck is a layer of gravel or compacted paver base to promote drainage and stability. Additionally, using concrete deck blocks or similar supports helps evenly distribute the weight and keep the structure level. These base materials help minimize moisture buildup, reducing shifting and rotting.

You have different options depending on the scale of repair needed. If you are repairing minor cracks that are between ¼ inch to 1.5 inch wide and less than half an inch deep, a self-leveling polyurethane sealant would be your best choice. Polyurethane sealants dry to the touch within one to two hours. Since they come in a tube applier, you also have the option to complete the repair without emptying out your garage.

The actual moisture level that is acceptable for your concrete floor depends on what primer or flooring material you plan to install above it. For this reason, you should check the manufacturer’s instructions for the exact details.

Generally, the moisture levels should be 3.5% to 4.5%, although it does vary. Some products can handle higher levels of moisture, so you should always test your concrete before purchasing your flooring materials.

Yes, concrete steps need rebar to reinforce the structure and ensure it can hold weight over time. Place a lattice of rebar inside the form before pouring concrete to give the steps their maximum strength. Tie each intersection together with rebar ties to hold the structure all together. Without rebar, concrete steps can sink, crumble, and lose their longevity.

What goes under your floating deck depends on your preferences. Some homeowners put landscaping fabric underneath their decks to prevent weeds from popping up through the boards. Others choose to build a floating deck over grass or gravel. However, it’s best not to set your deck directly on the ground. Instead, set your deck on blocks to keep it elevated enough to prevent moisture from rotting the wood.
