What Our Customers Say

“If you need someone who truly understands how to ‘play in the dirt’ and solve complex problems, these are the guys to call!”

— Dale M., Bellville, TX

“We were struggling with major drainage issues between our house and workshop, but they completely transformed the area. They smoothed out the old, overgrown creek bed to restore proper flow and carefully regraded the entire slope to ensure water finally moves AWAY from our foundations. It’s rare to find a crew so professional, prompt, and thorough with their cleanup.

Katy-Specific Questions & Answers

What makes Katy soil different? +

Katy sits on loamy clay soil — better draining than Richmond's or Sugar Land's heavier clay, but it still holds water longer than sandy soil, especially in the low, flat areas near the bayous.

What are common drainage problems faced by residents? +

Katy is flat, so heavy rain doesn't have anywhere to go fast. On typical yards, that shows up as water pooling near the foundation or gutters overwhelming the soil. On larger properties, it shows up as ponding in low fields and erosion along ditches. Either way, it's a grading and drainage problem — not something you have to live with.

Why does elevation matter? +

Katy runs low and flat, roughly 60 to 150 feet above sea level, and the lowest spots near the bayous and reservoirs hold water the longest. A little extra elevation on your lot goes a long way toward keeping water moving instead of sitting.

What does the permitting process look like? +

Katy spans three counties plus the city itself, so which office handles your permit depends on your address — but it's always a site plan, drainage report, and a few weeks' wait. We pull whatever's required and handle the process for you.

Why does proper compaction matter? +

Katy's clay soil expands when wet and shrinks when dry. Proper compaction packs out the air pockets so your foundation doesn't shift with the seasons, and keeps water moving through the ground the way it's supposed to.
