"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."

"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

If you don’t put gravel under concrete, the concrete can crack, sink, bow, or crumble. Even the concrete forming process will not go as smoothly if you are working directly on the soil or bare bedrock. The lack of a proper gravel layer can also lead to drainage issues below your slab, leading to water issues throughout your lawn and around your foundation.

Yes, you can seal an old concrete floor as long as you remove stains and repair damage before sealing. Remove everything from the garage and clear the floor throughout with a concrete cleaner and power washing. Fill in cracks larger than 1/8 of an inch wide and remove all grease and rust stains before sealing. Make sure your concrete is fully dried before applying sealer.

All foundations have footers, including monolithic slabs. In some cases, the foundation itself acts as the footer, as in the case of a floating slab and a monolithic slab. With a monolithic slab, the footers—which are just the bottom-most portion of the foundation that distributes loads down to stable soil—are a part of the main slab and are constructed with a single pour.

It’s possible to pour concrete if the temperatures are expected to dip below freezing at night, but you need to take some special precautions before you do. Most importantly, you need to make sure your concrete won’t freeze, so the best thing to do is enclose the area and heat it. You should also make sure you’re using cold-weather concrete that’s designed for pouring in cold weather. Use accelerants to help speed up the curing process and avoid cold temperatures from resulting in weak concrete.

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.
