"Working with DJ from Groundworks (Select Basement) has been an outstanding experience. After struggling with various contractors who either failed to resolve our water issues or were unprofessional, DJ and his team truly stood out. DJ was incredibly helpful, patient, and responsive throughout the entire process. Our home is a ranch with 225 linear feet around the perimeter, and while other contractors insisted on installing a French drain for the entire length, DJ recommended a more targeted approach. He proposed installing the French drain for just 80 linear feet, focusing only on the areas where water intrusion was likely. His thorough explanations and prompt responses to all our questions were greatly appreciated. The workers arrived on time, maintained a clean work environment, and completed the job as promised. If we could give 10 stars, we would! Groundworks is a highly professional and honest company that didn't try to inflate the scope of work to charge us more. We wholeheartedly recommend them."

"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

For most homeowners, wood and wood screws are the best materials to make concrete forms because they’re affordable, readily available, and easy to work with. Steel is a better concrete form material because you can use it thousands of times for repeated work, but this is most useful in commercial applications where one job is necessary many times over.

In general, you can expect concrete to last 30 to 50 years. However, the type of concrete, site prep, and climate all affect how long concrete lasts. The proper removal of rocks and tree roots before installation can prevent cracks later on. While concrete takes little maintenance, repairing small cracks as they appear can also extend the life of the concrete.

When pouring a new concrete slab, you should consider how additional costs will affect your total, including reinforcements, decorative enhancements, finishing, and curing. It's also important to consider local laws regarding the grade, drainage, and permits for installing concrete on your property. Speak with your professional about the ideal thickness for your slab, and also consider whether you’ll need drainage for slab longevity.

Underlayment is the barrier between the concrete floor and the hardwood flooring. Adding this barrier is a vital step when installing hardwood over concrete, and it’s essential for protecting the wood from moisture coming from the concrete. Some adhesives are also manufactured to contain a moisture barrier that can protect hardwood from moisture, even if it’s glued directly to the concrete.

Concrete dries faster in the heat than in the cold, but when concrete cures too fast, it can cause weak concrete. It’s best to pour concrete when temperatures are between 50 and 85 degrees Fahrenheit, watering it five to 10 times per day for seven days (unless you pour concrete in the winter). Slower cure times, such as when pouring concrete in cold weather, can cause strong concrete, but you need to monitor the temperature drop and moisture levels. Avoid pouring concrete when temperatures are below 40 degrees Fahrenheit.
