Guides
Written against the soil under Grand Junction rather than against national averages. Soil series and shrink-swell ratings, irrigation hydrology, crack diagnosis, pier methods, wall repair, drainage, and the numbers behind a quote.
Start here
The cornerstone. Why Grand Valley houses move, how the movement gets measured, which of the five repair families applies, what it costs, and when a Mesa County subdivision requirement means engineering.
Soils
The soil series mapped under Grand Junction with their shrink-swell ratings, why smectite clay swells, and what gypsum and sodium in the ground do to concrete.
Water
Nine inches of rain and a shallow water table. How a century of canals and flood irrigation created the groundwater under this valley, and what the seasonal on-off cycle does to a foundation.
Diagnosis
Reading a crack by direction, width, taper and location. Which are shrinkage, which are settlement, which are lateral pressure, and a five-step method for proving whether it is still moving.
Methods
How each type gets to bearing, what verifies its capacity, which structures suit which, and how pier count and depth assumptions should appear on a quote.
Methods
Carbon fiber, steel bracing, anchors and rebuilding, with the deflection thresholds that sort between them and the hillside and monsoon factors specific to this valley.
Crawl spaces
Why crawl spaces under irrigated lots stay damp in a nine-inch rainfall climate, how moisture becomes a support problem, and what encapsulation does and does not fix.
Water
The six water sources that reach a foundation here, how much grade fall to aim for, where downspouts should release, and an hour-long audit worth doing before spending anything.
Cost
Unit rates for every scope, what drives the spread, what quotes normally exclude, and a worked example on a real-shaped job.
Cost
What each line means, why two quotes for one house can describe different repairs, which assumption moves a total after work starts, and the six questions worth asking.
Soil series, linear extensibility values, gypsum content and water table depths come from USDA Natural Resources Conservation Service soil survey data for the Mesa County Area. Geology and irrigation hydrology come from US Geological Survey work on the Grand Valley. Climate figures are NOAA 1991 to 2020 normals for the Grand Junction Walker Field station. The subdivision foundation requirements list comes from Mesa County Building Department publications. The soil disclosure statute is C.R.S. 6-6.5-101.
Cost ranges are our own published estimates of Grand Valley market pricing, offered as a planning aid rather than as a quote.
