Move Stormwater Away Before It Does Damage
Maricopa County drainage rules require new subdivisions to hold the runoff they generate from a 100-year, 2-hour storm on site, a clear sign of how seriously the Valley treats stormwater. Mantek LLC builds the drainage services that manage that water, including stormwater systems, concrete catch basins, rip rap channels, site regrading, and retaining walls. We serve commercial, agricultural, municipal, and residential properties across Mobile, AZ, Goodyear, Buckeye, Avondale and the surrounding communities.
Our team brings 11+ years of concrete and site work to every drainage project, and that experience starts with reading the land. We study grades, soil conditions, and how water actually moves across the property before recommending a system. Then we build it to hold up through monsoon season, with transparent pricing and clear timelines. Request your free estimate through our contact page, and we will walk the site with you to plan the right approach.

Stormwater Drainage Systems
Collection inlets, underground piping, and outfalls work together to gather runoff and release it safely. A well-sized system keeps parking areas, walkways, and building perimeters from flooding during heavy storms, and it prevents standing water that damages paving and invites mosquitoes.
Site Grading & Drainage Solutions
Positive slope is the simplest drainage tool there is. Reshaping the ground so water runs away from structures and toward collection points reduces pooling, protects foundations, and often solves recurring problems without the expense of complex underground systems.
Concrete Catch Basins & Drainage Structures
Catch basins, junction boxes, scuppers, and cage basins collect surface water and route it into pipes or channels. Durable concrete construction resists heavy traffic and debris, while grates and cages keep trash and sediment from clogging everything downstream.
Irrigation Canals & Agricultural Water Management
Farmland depends on moving water deliberately, delivering it where crops need it and draining it where excess causes harm. Concrete-lined canals and control structures reduce seepage losses, limit erosion along banks, and make field water distribution far easier to manage.
Rip Rap Installation & Erosion Control
Channels, slopes, and outlets take the hardest hits from fast-moving water. Placing properly sized angular rock over filter fabric breaks up that energy, anchors soil in place, and stops the gradual washouts that undercut embankments, roads, and nearby structures.
Retaining Walls for Drainage & Soil Stability
Sloped properties need walls that hold soil and manage the water behind it. Weep holes, drain rock, and perforated pipe relieve pressure that would otherwise push a wall out of plumb, keeping hillsides stable and usable areas level.
Warning Signs Your Property Has a Drainage Problem
Standing Water That Lingers
Puddles that remain for hours or days after a storm show that water has nowhere to go. Over time that trapped moisture weakens the base under pavement and slabs, leading to cracking, potholes, and surfaces that sink in low spots.
Eroded Soil and Exposed Footings
Soil disappearing from slopes, flower beds, or the edges of foundations means runoff is moving too fast. Once footings or slab edges become exposed, the structure above loses support, and repairs grow more expensive with each passing storm.
Cracked or Undermined Paving
Water flowing beneath concrete washes out the supporting base, leaving hollow spots that crack under load. Sections that sound hollow, tilt, or break near edges and drains often point to a drainage issue rather than a problem with the concrete itself.
Water Stains Along Walls
Dark lines, mineral deposits, or efflorescence along building walls and stem walls show where water collects repeatedly. Those marks signal moisture sitting against the structure, which can damage finishes, corrode materials, and eventually affect the foundation if left unaddressed.
Clogged or Overflowing Basins
Basins that overflow during ordinary rain are either undersized, blocked with sediment, or fed by more area than they were built for. Ignoring the problem sends water across lots and roadways, spreading damage well beyond the original drain.
Sediment Washing Across Walkways
Mud and gravel spreading over sidewalks and driveways after every storm show that runoff is carrying soil with it. Besides the cleanup, that sediment creates slip hazards, clogs downstream drains, and gradually strips the ground that surrounding surfaces depend on.

Keep Summer Storms From Rewriting Your Property
Every property in the desert has to answer one question during monsoon season: where does the water go when it arrives all at once? Mantek LLC helps owners in Mobile, AZ answer that before the damage starts, pairing careful grading with concrete basins, channels, rip rap, and retaining walls built for the site's real flow patterns. Whether you manage a commercial lot, farm acreage, or a home with runoff trouble, the fix begins with an honest look at how water moves today. Contact us through our contact page to schedule your free estimate, and we will help you plan drainage that protects your investment through every storm season.

★★★★★
They do an awesome job! Really recommend on all the projects you can have with concrete or cement.
This walkway its beautiful
Manuel it’s really good guy and respectfully

It went fantastic. My driveway was sinking due to soil compacting. Manny gave a a prompt quote that was better than any of the other 3 I got. He answered every email and question, and was out within 10 days of my first contact. The work was done efficiently and well. The new drive is curing as I write and I would highly recommend the company to anyone in need

FAQ's
How is the right drainage solution chosen for a property?
It starts with site grading, water flow patterns, soil conditions, and how the property is used. Those factors show whether regrading alone will work or whether basins, piping, channels, or retaining walls are needed to control runoff reliably.
Can drainage improvements be added to an existing property?
Yes. Mantek LLC adds catch basins, regrading, channels, and erosion control to established properties across Mobile, AZ, correcting problems that original construction missed. Retrofits are usually planned around existing paving and landscaping to limit disruption to daily use.
What is the difference between retention and detention?
Retention holds stormwater on site until it soaks into the ground or evaporates, with no planned outflow. Detention stores water temporarily and releases it slowly into a drainage system, reducing peak flows that would otherwise overwhelm streets and channels downstream.
How do concrete catch basins work?
Surface water flows through a grate into a concrete box, where heavier sediment settles to the bottom. The cleaner water then exits through an outlet pipe toward a channel, retention area, or storm system, keeping runoff under control.
Do drainage systems need ongoing maintenance?
They do, though the effort is modest. Periodic inspections and clearing sediment, leaves, and trash from grates, basins, and pipes keep water flowing freely year-round. Checking systems before and after monsoon season catches blockages before they cause flooding or damage.
How does grading prevent water damage?
Grading creates a continuous slope that carries water away from buildings and paved surfaces. Even a gentle fall moves runoff toward collection points instead of letting it pool against foundations, where it softens soil and seeps into structures.
Can a retaining wall improve drainage?
A properly built retaining wall can, as long as water behind it has an exit. Free-draining gravel backfill and a collection pipe at the base let moisture escape while the wall holds soil, turning an eroding slope into a stable grade.
Do agricultural properties need a different drainage approach?
Often, yes. Farmland needs water delivered and drained on purpose, so Mantek LLC builds irrigation canals, control structures, and erosion protection for agricultural properties around Mobile, AZ, drawing on our 11+ years of hands-on concrete and site construction experience.
