What is Soil Injection & How it Works

What is Soil Injection Foundation Repair and How Does it Work It

Soil Injection and how it works – February 15, 2011 United States, Texas, Dallas

If you are looking for a cost effective foundation repair system, consider soil injection foundation repair. It is both a landscape friendly and an environmentally safe process. “There are environmentally friendly non-toxic, water soluble chemicals available such as potassium ions and ammonium salts. Make sure to ask your contractor what kinds of chemicals they are using and if they are environmentally friendly”, says Fred Marshall, owner of Advanced Foundation Repair.

Foundation problems are caused when soils under foundations either swell up as they absorb water or shrink as they lose water. Soil injection foundation repair (chemical injection) is a process designed to reduce or eliminate the ability of the soil to shrink or swell as the water content changes.

Consider this technique when upward movement has started to affect a small area under the foundation. It is best used when uplift is less than 1.5 inches and has not yet extended more than 10 feet towards the interior of the building. It does not remove the upheaval but stops the upheaval from increasing and/or spreading.

There is very little equipment needed – a truck equipped with 2 tanks containing the chemicals, pumps, hoses and reels and the injection wand.

In most cases, for existing structures, injections are done around the perimeter of a foundation. If there are driveways, patios, decks, or other paved surfaces, ¾ inch diameter holes are drilled through the paving to reach the underlying soils.

Workers use high pressure through wands to drive liquid into the. Approximately half a gallon to a gallon of liquid is injected for each cubic foot of soil that is being treated.

One technician monitors the process on a gauge to keep track of the volumes being injected while the other drives the wand down into the ground. Injections are typically made on two days to improve the results. The typical injection process takes two working days to complete. When it is finished, you should not be able to see where the soil injection took place.

Advanced Foundation Repair is a Texas company offering foundation preventive applications and repairs. Fred Marshall, founder and owner, has found that by using irrigation systems, drainage solutions, root and moisture barriers, plumbing services, construction services, foundation maintenance programs and slab repairs, Advanced is able to provide residential and commercial building owners multi-tiered foundation and construction solutions.

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
