Decorative Concrete questions, answered by experts

No, hairline cracks in concrete are generally not a problem as they do not impact the strength and longevity of the concrete. Generally, cracks less than 0.3 millimeter wide don’t impact the structure. Hairline cracks can grow over time and weaken the structure, such as in a home foundation. Some hairline cracks can also cause leaks in a foundation. It’s important to watch the cracks to see if they grow. Contact a concrete contractor if you notice cracks exceeding 0.3 millimeter wide.

Concrete can take up to 28 days to completely harden, depending on the type and its water content. But it dries enough for foot traffic in 24 to 48 hours. If you're curious about how long it takes concrete to dry entirely, the answer is more complex, so always check with the specific mixture instructions before adding heavy machinery or driving on new concrete.

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.

You can dry pour concrete over existing concrete, but it’s best to use wet pour concrete instead. Dry pour concrete is easier to apply, but in order for new concrete to adhere to old concrete, it needs the right mixture for slow, uniform curing. Additionally, dry pour concrete is less durable and less resistant to cracking and concrete sinking, so dry pouring over an existing slab may result in surface imperfections appearing prematurely.

Concrete pools are very durable but can crack if not properly maintained. The most significant risk is winter weather and low temperatures when water can seep into crevices and freeze. To avoid damage, use the proper winterization chemicals, and don’t completely drain your pool. Concrete pool repairs cost around $75 per linear foot for small cracks.
