Why is my retaining wall leaning forward?
This is caused by a massive buildup of hydrostatic pressure. If a wall is built without an engineered drainage system in the backfill zone, trapped water weight will eventually push it over.
Why do Corwin properties need engineered retaining walls?
Heavy masonry retaining walls engineered with clear stone backfill and perforated drain tiles to relieve water weight and survive Ohio freeze-thaw cycles.
Corwin is rural Warren County, where drainage problems cost just as much.
Corwin sits where the uplands meet the Little Miami. Near the village the soils are Russell, Miamian, Genesee, Wynn and Hennepin at about 8 to 11 percent each, with Casco gravel on the terrace. Wynn runs about 38 percent clay in the subsoil and hits shale bedrock about 31 inches down. Casco hits gravel at 16 inches. Well drained ground is 73 percent of the map. A wet Corwin yard usually points at grade, not soil. But a Wynn lot can hit shale under three feet and a Casco lot hits gravel at 16 inches, and either one changes the machine and the price for a wall footing or a trench.
Thirteen percent of the mapped ground near Corwin is rated for flooding along the Little Miami, and about 11 percent has a water table within two feet of the surface for part of the year. River lots answer to the river. Everything else in Corwin drains, and the work is about sending water the right way, which is usually a grade job before it is a pipe job.

COMMON SYMPTOMS WE FIX IN CORWIN
Why is dirt washing out from under my wall?
Severe base erosion undermines the structural footing of heavy masonry. This rapid washout is a clear indicator that the internal geotextile filtration fabric has failed.
What happens if a retaining wall fails?
A collapsing wall is a structural and financial mess. We terrace unstable land permanently using structural geogrids and deep aggregate bases to prevent mudslides.
"Our basement had flooded due to 5 inches of rain. Shawn corrected the drainage and grading issues, raised the yard so everything drains properly, and replaced failing concrete with a proper crushed limestone base."
