We at Perma-Pier pride ourself on our relationship with top professionals throughout the state of Texas. We recently had the chance to catch up with one of our longtime collaborators, licensed engineer Jeff Crannell of CCM Engineering, and ask him some questions about foundation failures, the differences between a home inspector and structural engineer, and why he chooses Perma-Pier as his foundation repair company of record:

PP: What are the most common causes of foundation failure?    

JC: The most common causes of foundation movement and failure are the active soils. These active soils shrink and swell based on moisture content. So proper drainage is a key factor. Another common cause is poor consolidation of the soil during construction.

PP: What’s the difference between a structural engineer and a foundation repair company?  

JC: Structural engineers are trained to identify structural problems and prepare repair recommendations – we don’t perform the repairs themselves. Foundation repair companies, while also trained to identify these same problems, are licensed to perform the actual physical improvements.

PP: My home was reviewed by a home inspector.  Do I need to get a structural engineer to look at it as well?   

JC: A home inspector is not licensed to provide a structural opinion, but they are knowledgeable in certain aspects of foundation stability. Oftentimes, the home inspector will recommend a buyer hire a licensed structural engineer to evaluate the foundation.

PP: How much foundation movement is cause for concern?   

JC: We follow the ASCE Guidelines for Residential Foundations, which states that a foundation should be level within L/360. This equates to 1” of deflection every 30’. Of course, there are other factors that go into the analysis, but this is the typical guideline we follow.

PP: With all this rain we have been getting, what is the best way a homeowner can maintain/ protect their foundation?  

JC: During rainy seasons, we recommend that the homeowner check the drainage around the foundation to make sure there is no standing water.  During dry seasons, we recommend that the homeowner water the soil around the foundation.

PP: What is the most common mistake you see foundation repair company’s make?  

JC: The most common problem we hear from homeowners is that the repair company will not honor their warranty.

PP: Would you recommend Perma-Pier for foundation repair?  

JC: Yes we would. In fact, we recommend Perma Pier to our clients.

PP: Finally, what sets Perma-Pier apart from other foundation repair companies?  

JC: You have a long history of quality work and I think the company will be around for a long time.  This history and healthy growth as a company is important since it means your warranty is actually worth something, unlike other companies that come and go, change their names, etc…
