"We paid close to $20,000 to BQ Basements to completely waterproof our basement. We still get water and they told us we need another sump pump installed at over $2,000. They guaranteed we would not get water after installation. Be aware they do not stand behind their work or honor warranties."

Concrete Leveling questions, answered by experts

No, wet concrete will not bond to dry concrete without an additional bonding agent. The common alternative is adding a sand or gravel layer under a concrete slab to enhance bonding and create a stable foundation. The right choice depends on the height and thickness of your two slabs, local laws, and the use of the specific concrete slab.

On average, 6 inches of concrete can hold around 150 pounds per square foot, but the exact weight that 6 inches of concrete can hold depends on factors such as the type of concrete, the reinforcement method, soil conditions below, and structural design. If you’re concerned about the longevity of your concrete patio, walkway, or driveway, hire a professional to help you choose an appropriate concrete thickness and reinforcement method for your needs.

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.

Concrete floors are durable, low-maintenance, and customizable with various finishes and colors.

Yes, concrete can set in rain, but it’s best if you pour concrete 4 to 8 hours before any rain to ensure it won’t impact its strength and appearance. Exposure to heavy rain during the early stages (the first 48 hours after pouring) can significantly reduce the structural integrity of the concrete. Over time, cracking is more likely due to softer concrete.
