This article explains wood building foundations, their inspection, installation, diagnosis, repair, and durability. InspectAPedia tolerates no conflicts of interest. We have no relationship with advertisers nor with topics or services discussed at this website.Also see TERMITES, ROT. Page top sketch of a basic wood foundation design is provided courtesy of Carson Dunlop Associates. Types of foundation cracks, crack patterns, differences in the meaning of cracks in different foundation materials, site conditions, building history, and other evidence of building movement and damage are described to assist in recognizing foundation defects and to help the inspector separate cosmetic or low-risk conditions from those likely to be important and potentially costly to repair. Also see this close companion article: FOUNDATION CRACK EVALUATION which discusses in detail the process of evaluating foundation cracks and signs of foundation damage by examining the crack size, shape, pattern, and location. © Copyright 2012 InspectAPedia.com, All Rights Reserved.

Our opinion is that "30-year guaranteed treated wood foundation products" used below grade mean that no permanent building foundation has been provided. This sketch of the components of a preserved wood foundation is courtesy of Carson Dunlop Associates. Buildings using a wood foundation are in our OPINION a temporary structure. In areas of wet soils and insect damage risk damage may occur sooner than the warranty period. CONTACT us by email to suggest photos or content regarding wood building foundations. Note: use of plumb lines, levels, laser levels, & simple measurements of amount by which a wall is out of level or plumb, or of crack widths and patterns are beyond ASHI or other home inspection standards scope but are common simple tools and procedures used by masons, carpenters, builders, as well as foundation experts and engineers. Below are some articles that offer additional foundation damage analysis methods that pertain to wood foundations as well as other foundation types:
