Under Slab Tunneling


Under slab tunneling is used to gain access to the interior of your home, without having to break a hole in your floor.  Nice!  Generally, tunnels are as long as needed to reach under your home, and measure 3 feet by 3 feet in cross section.  



Tunnels enable Advanced Foundation Repair to reach the parts of your foundation that are under the interior of your home, without having to come inside of your home.  Tunnels avoid the need to break holes through your slab, to tear out carpet, to cut through wood or tile floors, or to otherwise invade your home. When your home is lifted, with tunnels, you can stay in your home, you do not need to remove furniture, or to move out of your home.  Advanced has lifted homes over 12 inches while the owners remained inside!  

Under Slab Tunneling  vs Cutting Slabs for Foundation Repair How-to websites and blogs are full of questions on whether to tunnel under a house or cut slabs for plumbing and foundation repairs. Some are tunnel only advocates while others push the slab cutting alternative. There is no one size fits all regarding tunneling under a house or cutting through concrete slabs. Each repair situation is different and needs to be evaluated on its own. View Script >>



Generally, your tunnels are connected to a drainage system used to keep water from accumulating under your home.  In some cases, your tunnels will be connected to a gravity drain, in others, to a sump pump. Tunnels should be left unfilled to facilitate any future plumbing repairs (after all having gone through the expense of digging tunnels, you might as well get full advantage of them) or foundation warranty work.  



Tunnels are dug to allow pilings to be installed.  Pilings are used to hold up your foundation.  Once pilings are installed, your home is no longer sitting on the soil.  It is simple, since the pilings are holding up your home, it does not matter if the walls of your tunnels crumble.  



The old fashioned way, we dig your tunnels by hand.  This is extremely difficult work, but is worth the effort.

Tunnels typically cost about $165.00 per foot to dig and drain.

Workers were very professional and hard working. They dug up around the house and put plants back to look nice. This company also has a trust to forever be able to redo warranted work.read more

I can't too highly recommend this company. I had work done of my foundation by another company several years ago. That work did not resolve the problem, and that company did not fix. Advanced was recommended to me by mother, who said they were the best in the business. I agree! They were polite, professional, charged reasonable prices, and did excellent work. They also have a strong guarantee that is backed by a trust. I can't imagine why you'd use any other company.read more

Advanced Foundation repair is the only way to go! The engineer, Eric was kind, helpful and informative! The crew under Haynard's watch was unbelievably considerate. The crew was in and out of our house for 5 days. Everyone of them were happy even in the 90 degree weather. They work hard and were very polite. If you saw my house now you would never even know they were here. They cleaned up every night and on the last day it looked like new! Very thankful to have been able to work with them.read more

Advanced recently performed our foundation repair and did a fantastic job! The job took four days and throughout the process, the workers were on time each day, were kind and courteous. They left our house clean each day and took great care in making my wife and newborn comfortable during the repair. They came back out to make adjustments, as was expected, and I am more than pleased with the results. Thanks to Juan Martinez, Miguel Mata and Ernesto Alvarato for doing everything I requested. I highly recommend Advanced Foundation Repair, they know what they are doing.read more
