Drainage Problems We Solve

99% of East Valley drainage problems come down to one thing: water that was never graded to flow away from the structure in the first place.

01
Standing Water & Flooded Yards
Water pooling in your yard after every storm means your lot isn't draining. We re-grade to establish positive drainage that actually moves water away from your home.
02
Water Migrating Toward Foundation
The most urgent drainage call we get. Water tracking toward a slab or foundation needs to be fixed fast — we assess and correct grading before it becomes a structural problem.
03
Swales & Berms
Directed drainage paths that move sheet flow where it belongs, built to Maricopa and Pinal County standards.
04
Retention Basins
When code requires water to stay on-site, we design and build retention that holds the required volume and drains within the mandated window.
05
HOA & New-Construction Drainage Fixes
Drainage that was never installed correctly by the original builder or landscaper — a problem we see constantly across East Valley HOAs.
06
Post-Monsoon Regrading
After a bad monsoon season exposes your lot's weak points, we regrade and correct so it doesn't happen again next July.

The East Valley Gets Hammered Every Monsoon

It's Almost Always a Grading Problem

Every monsoon season, R² Contracting gets calls from East Valley homeowners dealing with standing water, flooded yards, and water migrating toward their foundation. Nine times out of ten, it's not bad luck — it's a lot that was never graded to point water away from the structure in the first place. Sometimes it's the original builder cutting a corner. Sometimes it's a landscaper who didn't account for slope. Either way, it doesn't fix itself.

The Fix Depends on Your Lot

A simple re-grade solves a lot of problems — establishing the 1-inch-per-foot slope away from the structure that Maricopa and Pinal County expect over the first several feet. Other lots need a swale or berm to redirect sheet flow around the house. In more severe cases, especially where code requires it, a retention basin keeps water on-site and drains it within the required window. We assess your specific lot and build the right solution — not the cheapest one that fails next July.

Caliche Makes This an Arizona-Specific Problem

Arizona's caliche hardpan doesn't absorb water the way normal soil does, which is exactly why East Valley yards pool and flood even after a moderate storm. Fixing drainage here means understanding how caliche behaves — not just applying a generic landscaping fix.
