"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."

"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."

Down Under Waterproofing, Inc. is a family-owned business that has been providing basement waterproofing, foundation and structural repair, basement finishing, stucco, retaining walls and masonry services. to the New Jersey and Eastern Pennsylvania areas since 2006. As a fully qualified, licensed and insured waterproofing and foundation repair contractor with over 2000 satisfied customers, we enjoy an excellent reputation and employ only the most effective and widely accepted methods in the industry.

"Walt, Max, and the whole crew were absolutely amazing. This was a HUGE project. We basically had no foundation on the back/ side of our house and the 2nd floor overhang was poorly supported. Prior to us purchasing the house the previous owner added a very large addition on top of a very old and poorly constructed “house” . The inspection at purchase did not uncover the issues that we found about two years after when all of the cosmetic touch ups wore off. Walt’s crew ( Supervised by Max) replaced the foundation wall , added piers under the house, replaced all of the floor joists along with new piers, beams, and headers on the 40ft span at the back of the house. This is just some of the larger items because I would be here forever if I listed everything they had to do. Walt kept us informed during the whole project. From start to finish we were on the same page. The house had so many hidden issues but the crew worked through all of it. The price was very reasonable and less then all of the other estimates from competitors. We didn’t have a bunch of surprise increases along the way. He didn’t try to scare us or sell us anything we didn’t need. They are honest and reliable. The results were amazing and so far beyond our expectations !!! They are all so talented. We couldn’t be happier with our choice of contractors!! They have been done for almost a week and we miss them being here already. I will recommend them to everyone."

Concrete Leveling questions, answered by experts

Yes, you can mix your own concrete for smaller jobs using premade bags of concrete. All you have to do is add water. There are different kinds of concrete, so make sure you get the right type for the job and mix according to the instructions. Too much or too little water can undermine the strength and durability of the final product.

Minor hairline cracks in your concrete may not look pretty, but they’re often not serious. It’s when concrete cracks are larger—wide enough that you can slide a credit card into it—that you need to worry. If you monitor a crack and can trace its active expansion over time, you’ll definitely want to call in a pro to inspect it and, potentially, repair it. Want to prevent cracks in your garage and driveway concrete in the future? Stay on top of sealing. Here’s how to seal your concrete garage floor and driveway.

The most common cause of concrete cracks is shrinkage when the concrete hardens and cures. The stress from the shrinkage exceeds the concrete’s strength. Concrete cracking can also occur when it experiences extremely cold or hot temperatures, such as a particularly harsh winter or a firepit built into a concrete patio.

Yes, including sustainable mixes and reflective surfaces to reduce heat absorption.

In most cases, you’ll want your patio to be 4 inches thick, although you should add reinforcement and increase the thickness up to around 8 inches if you want it to support heavier loads and resist cracking more readily. Although thicker slabs will cost more, you’ll start seeing diminishing returns at around 6 inches.
