Richmond Concrete Pros - Foundation Repair
The root problem
There are a number of things that can go wrong with a foundation that can get progressively worse over time if not addressed.
Proper foundation prep is a technology that has evolved over the years. Building standards are now such that these types of problems are far less common than even 10 years ago. The soil beneath the foundation must be able to hold it solid and not sink and shift. If it does sink or shift, the foundation is likely to start developing cracks and beginning to slowly settle. These can start out as hairline cracks but will eventually grow until you can see through them. They will keep growing and other issues like water penetration under the house, wall cracks, floor settling, and window and door issues will start to occur.
The majority of settling problems are caused by water. Varying moisture levels in the soil cause it to swell and shrink, leading to movement below the foundation causing destabilization. Other characteristics or events that could lead to problems are:
- Extreme seasonal changes
- Poor drainage around the foundation
- The soil below the foundation were not properly compacted
- The foundation was built on top of certain clays
- Tree roots
- A plumbing leak in the crawl space
Richmond Concrete Pros has the experts on staff to analyze and fix these types of problems. It can be difficult to find a single company that can handle all these different types of problems and issues under a house but we have dealt repeatedly with every one of them. Lets have a look at each one but first lets examine the likely root cause of most of these.
If you catch the problem early enough, the foundation can be braced and repaired before too much residual damage occurs. But this is often not the case. Frequently homeowners simply ignore these issues until the problems are severe and obvious. Foundation issues evolve slowly over time, but time is not on your side.

The first type is called a French Drain. For what it's worth, these may have been invented in France, but the invention of this style of drainage system is attributed to a man named Henry Flagg French from Massachusetts in the 1860's.
This is basically a trench dug around the foundation, sloping away from the foundation, in which is placed a perforated pipe. The trench is then backfilled with a porous material, typically gravel, to fill the trench and allow the water to pass down into the pipe where it is channeled away from the house where it can be disposed of without causing any harm.
