Q: What causes foundation problems?
A: The most common cause of foundation movement is the seasonal shrinking and swelling of expansive soils. The degree of soil movement is determined by the amount of expansive material in that soil and the variation of its moisture content. When the moisture content of expansive soil increases, the soil swells. During the drier months when the moisture decreases, the soil shrinks and achieves its lowest moisture content, allowing foundations to settle. During the wetter months, foundations return to their desired elevation. At times, the soil will swell enough to raise foundations higher than their desired elevation, which is referred to as heaval.

Poor site drainage is a common cause of foundation movement. Surface and subsurface moisture should be diverted away form the home or building in order to preserve the strength and desired elevation of the foundation system. Good site drainage is very important to prolong the life of a structure. Another cause of foundation movement is building on improperly compacted fill. Improperly compacted fill will consolidate or pack down under the load of a home or building. Moisture problems will contribute to consolidation of non-compacted fill.

Plumbing leaks are another common cause of foundation movement. these problems are often created during the initial construction of a home or building; however, leaks may not occur for many years. Our experience has been that plumbing leaks, whether they are in supply lines or in waste lines, always cause foundation and/or floor movement. If major foundation movement exists, plumbing tests are often recommended to check for plumbing leaks.

Poor construction is also a major cause of foundation movement. This problem often begins during the initial design of a home or building. Some foundation systems simply are not adequate for the areas and soil conditions in which they are used.
Q: How do I Know if I have a foundation problem?
A: The only way to be sure is to have one of our foundation estimators conduct an onsite evaluation. If there is a foundation problem we can remedy, the estimator will provide a repair plan and price quote on site. If the estimator finds no problem with your home's foundation, we can provide you with a letter documenting the findings.
Q: How do you determine what needs to be done?
A: Depending on the complexity of the home foundation problem, our professional inspector will inspect your home's exterior and interior and take elevation readings of the interior. After the inspection, he will match the structural indications with the elevation readings to create a complete picture of what stresses are being exerted upon your home. Finally, a detailed floor plan and repair proposal is designed and the inspector will explain all aspects of your home foundation situation.
Q: Do I have to repair my foundation in order to sell it?
A: There are latent defect disclosure laws that prohibit a homeowner from patching up cracks to cover a foundation problem and selling it to an unknowing buyer. Most mortgage companies will not issue a loan on a house to be purchased unless the foundation is repaired. The only exception would be a cash buyer who is willing to accept the house "as is."
Q: Does insurance cover the cost of foundation repair?
A: Most standard homeowner's insurance policies state that foundation repair is covered only if the damage is the result of a plumbing leak.
Q: How long will my foundation repairs take?
A: The average foundation repair job takes 2-3 days. Depending on the scope of work, the time frame may be greater.
Q: Why concrete instead of asphalt for my driveway?
A: While the initial cost of concrete is more, the long term cost is less because concrete life is two to four times that of asphalt. The strength, durability, maintenance, flexibility, and versatility of concrete is much better.
Q: Concrete is concrete, it doesn't matter who puts it in.
A: This is simply untrue. It matters very much who installs your concrete. Here at J&J Foundation we take pride in our work. Some companies don't stand behind their work, but we offer warranty. We pour our concrete thick, we use steel re-bar in everything we pour and we have certified finishers on staff. We love concrete and we believe we're good at it.

The most common is poor planning at the construction stage. Clay, soils, guttering, inappropriate drainage, and a lack of watering also...
