"I’m a 70 year old Senior. I had sagging at the end of my hall, in my 3-BR ranch home. I got five other quotes, none of which suggests a problem with my foyer or kitchen. They sent out some 20 something young man -that clearly did not know what he was doing to complete my main beam replacement project. I mentioned to David (the 20 something) and his assistant IMMEDIATELY, that my kitchen cabinets had pulled away from the wall and the foyer was tilting. Several times. He assured me that he would run the beam right up under the kitchen between the kitchen and the foyer, to the garage door —to correct it! I had an intense disagreement with him when he tried to leave and did not make any attempt to correct the damage. The damage they had caused. I used my burial money to correct this sagging in the hall-and they left me with a huge problem with my foyer and kitchen that WASN’T THERE BEFORE, that they caused, & knew they caused. Indiana foundation, now Groundworks, sent Blake to my house under the guise of completing my first adjustment to the main beam, and as I had instructed them, to formulate their repair project based on a certified Home Inspection Specialist that I had hired to let me know what, specifically, Ind Found. should do to correct the serious problem they created. They promised to schedule the repair work at that time, but have ghosted to me ever since coming to see the damage they caused and formulate the repair. I have not been able to get in contact with them since; I’ve left numerous v-mails and texts. They have no integrity towards my project and nor will they have ANY integrity towards yours."

"Salesman here 6 hrs. Quoted over $30lk got down to $25,500. Of course it was a good for today sign now price I had more estimates lined up but after 6 hrs and him acting like he was my husbands new bf and beer buddy he signed. Scheduled walkthrough- that was cancelled. Started work and had ?issues? that walk through would have found. Blew circuit breaker in workshop of basement, we now need an electrician bc even w replacing the circuit breaker w a new breaker it still turns off. Quotedi time length/ what they would be able to do by salesman- all wrong. Workers say it will be twice as long and what sales man said they could go around they can not. Workers are extremely polite and nice. Will update review when they are finished w work. Today 7/30 will be day 3. "

"I know this is a book, but please read before contacting them. I don't consider this project completed but it was the only way that I could write a review. We still have 1 major issue that I can't get them to fix. I was stupid & paid because they said they would be out to fix the encapsulation. Double stupid because I trusted them. 3 months - still not fixed and now we have water in the crawlspace. Phase 1 took 11 days instead of 3 - a lot of crawlspace work (broken water pipe that they did not break.) Phase 2 was and still is a disaster. Scheduled for 13 - took 34 days. New subflooring (2 - 4 ft) was needed on all outside walls, a main beam, jacks.. We still have unlevel floors, we have uneven matching between new and old subfloor (+ other issues). The project manager did fix some of the issues. It took 7 weeks (renters living in the garage, rent free because that was fair), to complete and fix some of the issues. But the wall encapsulation is still laying on the ground - in water."

Basement Waterproofing questions, answered by experts

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

If your basement often leaks after heavy rain, it’s probably caused by hydrostatic pressure. When the ground is saturated with water, it can put pressure on the exterior of your home’s foundation, causing cracks in the basement wall and pushing water through any existing weak spots. Over time, hydrostatic pressure can cause structural damage to your home.
