Here is what nobody has told you about New Orleans foundation drainage.
Every property in Orleans and Jefferson Parish sits on Schriever clay — a soil type that absorbs almost zero water per hour under normal conditions. When it rains, that water does not go into the ground. It sits on top of it. It pools. It presses against your foundation.
Your landscaper knows about the symptom. Your drainage contractor knows about the symptom. Your foundation company knows about the symptom.
None of them have measured the source — the actual hydraulic performance of your soil at depth.
Garden Picasso does. The Forensic Infrastructure Audit establishes your site's GPH baseline and delivers a Certified Infrastructure Risk Report in 7 business days.
The only diagnostic of its kind in the Gulf South.
