Don’t let water intrude in your crawlspace any longer. A French Drain collects water around your foundation before it can enter and cause water damage or mold growth.
A rising water table is a problem for your home, and understanding your options for keeping you crawlspace dry can save you a lot of headache and money. French Drains are designed to absorb surface water or to absorb underground water from a rising water table, or both, as in the case of a perimeter drain. A perimeter drain should be installed at the bottom of the footer, below the waterproofed foundation wall to collect water that would otherwise enter the basement or crawlspace.
French drains are often installed with a sump pump so that the water is collected in the French drain as it rises and then pumped away by the sump pump.

What makes french drains french? Did the French invent the drainage solution? What about drain tiles? Aren’t they made with corrugated plastic pipe or PVC? The truth is, these are no more French than English or Spanish drains. Henry Flagg French transformed drainage water management from a downwards sloping trench filled with gravel to the use of clay, half circle roofing tiles formed into a pipe with a ⅛ inch gap between the tiles buried in gravel to allow water to travel downhill without causing erosion. Other names they are known by is French ditch, perimeter drain, sub-soil drain, rock drain or agricultural drain.
Modern French drains are made with 4” corrugated plastic or PVC pipe. They are covered with a mesh filter fabric that allows the water to enter but filters out the soil. They are buried in gravel or foam pellets to allow the water to follow the path of least resistance to the pipe. A new “all in one” French Drain has been developed by NDS called the EZ-Drain. Tier use’s this one when there is no danger of crushing, otherwise, we recommend PVC with holes in the bottom, wrapped in a filter fabric sock, surrounded by gravel.
A “downstream” approach is to install a French Drain on the inside of the basement or crawlspace while installing a membrane on the inside wall of the basement to allow the water seeping inside to run down to the drain. The downside to interior French Drains is that erosion can occur over time and possibly create a problem for the foundation. However, sometimes the cost and disruption of the exterior waterproofing solution make the risk of an interior drain more preferable.
Many perimeter drains and waterproofed foundation wall systems fail over time or were never properly installed. The best way to fix it is to dig the dirt away from the foundation wall and start over with new waterproofing membrane and coating for the wall and new French Drain, then backfill with gravel and dirt as necessary.
A rising water table is managed only by a French Drain and sump pump system. The water is collected in the French drain as it rises and then pumped away by the sump pump. A curtain drain is a variation on the French Drain. A series of french drains are installed diagonally across a hill, from top to bottom so surface water is collected into the French drains and directed to a drain on the side thereby preventing erosion on the hill.

TOP notch folks. Called and got an immediate response. I called them in a hurry and they showed up the next morning to do a mold test. Very helpful and professional and I will use them again!!!
I had nothing but a wonderful experience with Tier. They were on time,very friendly and knew exactly what they were doing. I had a spot that I'd had for 4 year on my carpet and figured I would have to replace that carpet but they got it out after a couple of tries. I was truly amazed. Alex, the manager, I'd worked with before and I can't say enough good things about him. He's always there when you need him with a solution for whatever your problem is. He has a very positive attitude and is great to be around. All in all my experience was fantastic!
I honestly believe you won't find a better company to work on your home than TIER. Alex has always given me more than fair estimates and exceeded all my expectations with the final product.
Most recently, TIER installed an interior french drain in my house. Alex came out to my house through all stages of the project. He even did a final walk through and decided that he was not satisfied yet and told me he would send his guys out to bring it to his standards. I can't stress how rare this is.
Until working with Alex and TIER, I had not found a company in Nashville that I trusted. They are the only company in Nashville I would feel comfortable recommending to a friend.
Greg Lewis Tier Restoration is committed to doing the best work. The company's slogan, “Experience The Next Level” really describes Greg's work ethic as a professional in his field. He is a great resource for folks who need help with their homes. Greg and his team are folks to be trusted!
I've been selling homes for over 30 years and have owned rental properties for over 10 years. Tier Restoration is by far the best company of its kind I have ever used. As a real estate Broker selling hundreds of homes a year it is empowering to have a company as competent and professional as Greg Lewis and his crews. As a landlord I have personally used them twice in the past 12 months on major situations. The kind of challenges that would cause many to lose sleep over. In both cases Alex took my fear and concerns I was facing and extinguished them all by his consistent timely communication and professional awareness throughout the process to completion.
From simple duct cleaning to major foundation and crawl space repair and remediation there is only 1 company that I call. They are simply the best!
The Tier group were amazing!! From the moment they walked in my front door, I knew we were going to be in good hands. The work was professionally done, and the communication was outstanding. Don't waste your time looking at other restoration companies, choose Tier and have that peace of mind that we had!!
Alex and his team are amazing to work with. Everyone is courteous, on time, and thorough in their work. Alex stops by to personally check on his crew and talk with the homeowner. I highly recommend Tier Restoration and will certainly use them again and again.
