"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."

Providing wide range of contracting services for all their remodeling. we look forward to have the job complete as what was you excepting.

"Unprofessional Work and Product is Trash Would strongly recommend choosing a different contractor and not getting involved with these unprofessional crooks. Overpriced, unsettling experience including disrespect of property and random price increases, and finished product is complete trash. Looks horrible and is falling apart. Last October paid well over $8,000 to have about 20ft by 15ft of concrete poured in the backyard. Within 6 months the concrete has holes, dents, cracks, and is crumbling apart. During the job the workers left many beers cans, trash, and cigarette buds all over the property. Concrete was poured all over the fence and chunks of concrete ruined the front lawn. Dents were left on the newly poured concrete from day 1 and continue to worsen. He said he would rectify the situation, agreed the finished product needs to be redone, and then disappeared and has been unavailable to contact."

Concrete Leveling questions, answered by experts

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.

Vinegar has become popular because it’s wallet-friendly, easy to find, and sounds like a great alternative to harsh chemicals and expensive machinery. However, vinegar isn’t strong enough to remove concrete sealant. Sealants can resist acid, and vinegar is a much weaker acid than chemical removal agents. And worse, vinegar can damage concrete by dulling it and causing pitting.

If you're only working with a gravel pad, and there is no concrete foundation, you might be able to upgrade to a concrete slab, but you’d have to speak with a professional concrete expert to confirm and get pricing. If you have a concrete foundation or cement block walls around the area where you want to build flooring, you might be able to pour a new concrete floor over the existing one to forgo repairs. Again, speak with a concrete expert or foundation company to see if this is an option.

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.

If you over-trowel concrete, it will be difficult for moisture to move through it. For this reason, it may be worthwhile to hire a professional, especially if you don’t have the advanced knowledge and techniques required to avoid this issue.
