"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."

We are a family owned and operated company that takes great pride in a job well done. We have been fixing foundations for three generations.

"This company repaired all wall cracks in my basement and installed a drain system on all walls of my basement. This company showed up when they were suppose to and completed the work on my basement in a timely matter. I had to contact this company to come back out after the work was done but come to find out, the problem we experienced was not due to any of the work this company had previously done however they still repaired the problem without charging us anymore money. Would definitely recommend this company to others."

Basement Waterproofing questions, answered by experts

Brick is designed to absorb moisture, but it is also designed to let it evaporate as well. So in general, the goal shouldn’t necessarily be keeping moisture out but making sure it has the room to breathe. If you have excess moisture getting through your brick wall, it’s more likely that you have a crack or other issue at play that a typical sealant won’t fix. So, instead of investing in sealant, try repairing your brick wall instead.

Yes, many repair services include reapplying waterproofing and UV-resistant coatings.

Proper drainage is the only way to ensure that your crawl space stays dry. Depending on your property and the extent of your issue, you might need to consider a gutter system, a French drain, or sump pumps to avoid and handle water and moisture under your home. Dehumidifiers can also help to prevent moisture from accumulating if you have a high-humidity environment.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.
