Special Contractor and Owner Information with regard to Residential Foundations on Ground
- Trees or other vegetation with a mature height greater than six feet or which require excessive amounts of water should not be planted or
located within 20 feet of the foundation in order to minimize any effect on the foundation.
- Excavations such as swimming pools and for retaining walls shall not be placed closer than 10 feet to the foundation.
- The grade shall slope a minimum of 5 percent with 10 percent preferred in the first 10 feet away from the foundation. The maximum slope
shall be 15 percent in the first 5 feet and 30 percent after 5 feet unless approved by the engineer.
- Water shall not be allowed to pond next to the foundation. Downspouts shall be directed away from the foundation to direct the water at least
10 feet from the foundation.
- All slabs on ground are designed and assumed to deflect. It is the intent of the geotechnical investigation and the foundation design to
minimize this deflection and therefore, the associated distress (cracking in walls and sticking doors, etc.). However, the owner should be aware that some deflection and distress is likely to occur. Proper geotechnical investigation, foundation design, construction techniques and homeowner maintenance are all necessary to minimize the potential distress if a slab on ground is chosen as the foundation type (in lieu of a structurally suspended foundation). The undersigned acknowledges that a geotechnical investigation is a representation of the soil at the location of the boring and that the soils may vary between borings. The tests and boring logs are a representation of the soil, but all guidelines, opinions, and recommendations are the opinion of the Professional Engineer who seals the design or report. As a professional opinion, there is no warranty or guarantee, expressed or otherwise, to the accuracy of the opinion since it is based on assumptions and somewhat unpredictable soil properties. The undersigned; holds Whitworth Engineering and its employees harmless for any damages to any structure built on the site of the investigation, and agree to pass this indemnity on to the owner and user of the real property.
