Standing water and poor runoff destroy pavement and foundations. We design and install drainage systems that move water off your property and keep it gone.
Drainage solutions in San Bernardino correct the slope, add inlets, or install underground pipe to move water away from pavement and structures. Most residential jobs - a French drain, a catch basin, or a surface regrade - are completed in one to two days and deliver lasting results.
Water that sits on asphalt or against a foundation does not just cause inconvenience. It softens the base beneath pavement, accelerates cracking, and can shift concrete over time. In San Bernardino, winter rain events can be intense when they arrive, and the clay soils in parts of the valley drain slowly - making a proper drainage system especially important here. If you already have water-related damage, pairing drainage work with grading and excavation creates a solid foundation going forward.
If puddles form on your driveway or parking lot and stay for hours after rain stops, the surface lacks proper slope or an adequate outlet. That standing water seeps into the asphalt base, causing soft spots that later crack or sink. Every rain event makes the problem worse.
Cracks that appear along the edges or low points of a paved surface often trace back to water pooling and weakening the sub-base. The pavement itself looks like the problem, but the cause is water that has no place to go. Repairing the surface without fixing the drainage leads to the same cracks returning.
When runoff consistently flows off a paved area and onto bare soil, it erodes the ground at the edge and can undermine the pavement itself. This is especially common along driveway borders and at the back of parking lots. Left untreated, the pavement edge loses its support and begins to crumble.
Runoff that flows toward a building rather than away from it pushes moisture against the foundation. Over time this can cause efflorescence, cracking, and in severe cases structural movement. Redirecting that water with proper grading or drainage channels protects the building as much as the pavement.
We handle drainage problems across residential and commercial properties in San Bernardino and the surrounding Inland Empire. For properties where the pavement itself is directing water the wrong way, surface regrading reshapes the slope so runoff moves toward a safe outlet. When the volume of water is too large for simple slope correction, speed bump installation projects sometimes coincide with drainage work when a parking lot redesign is underway. Every drainage project starts with an on-site assessment - the fix depends on where the water is coming from and where it needs to go.
French drains use perforated pipe surrounded by gravel to collect subsurface water and move it away from pavement edges and foundations. Catch basins and channel drains are surface inlets that intercept runoff at low points and carry it through underground pipe to a safe discharge point. For properties that need a complete ground-up solution, grading and excavation sets the correct base grade before any pavement or drainage system goes in. We recommend the approach that fits your property and your budget.
Ideal for properties with subsurface moisture or chronic wet areas along pavement edges and foundations.
Best for paved surfaces with low points where surface runoff collects and needs a direct outlet.
Suited to driveways and parking lots where the slope is incorrect and can be corrected without full reconstruction.
For sites where water needs to be carried a longer distance to a safe discharge point or existing storm drain connection.
San Bernardino sits on the valley floor with alluvial and clay-heavy soils in many neighborhoods. Clay soil absorbs water slowly and swells when it gets wet, which is a problem for any pavement sitting on top of it. When winter rain arrives - especially in heavy atmospheric river events - that water has nowhere fast to go. Properties without proper drainage systems end up with pooling on driveways, soft spots in parking lots, and pavement that starts cracking from the base up. The foothills on the north side of the city face additional runoff pressure from slopes that concentrate water before it reaches the valley floor.
We see drainage problems across the whole area - from older neighborhoods in central San Bernardino to newer commercial strips near the I-10 corridor. Customers in Rialto and Colton often call us after winter rain seasons expose drainage issues that summer heat had been hiding. Getting the drainage right means your paving investment - whether a new driveway, a parking lot resurfacing, or fresh sealcoating - holds up through future rain seasons instead of failing all over again.
Call or fill out our contact form and describe the water problem. We schedule a site visit - usually within one business day - to walk the property, identify where water is entering and where it needs to go, and assess the existing pavement and soil conditions.
After the assessment, you receive a written quote that specifies the type of drainage system, the materials, and the total cost. There is no obligation to proceed. We answer any questions you have so you can make an informed decision without pressure.
On installation day, the crew excavates the necessary areas, installs pipe or drain components, and backfills and compacts properly. Any pavement that was cut for access is patched cleanly. Most residential jobs wrap up in one to two days.
We walk the finished work with you before leaving, confirm the drainage flows correctly, and leave the site clean. If any follow-up is needed - such as pavement restoration over excavated areas - we coordinate that as part of the project.

The San Bernardino valley floor has a mix of alluvial and clay-heavy soils that drain slowly and shift with wet-dry cycles. We account for local soil behavior when sizing systems and setting pipe grades - not just generic drainage formulas.
Most drainage problems affect the pavement above them. Because we handle both drainage installation and asphalt paving, we can address both in a single project rather than hiring two contractors and coordinating schedules. That saves time and money.
California requires a valid contractor license for excavation and drainage work. You can verify any contractor license at cslb.ca.gov before you hire. Licensed contractors carry the required insurance and stand behind their work legally.
Drainage estimates can be vague when contractors are not specific about pipe depth, inlet type, and outlet location. Our written quotes specify all of these details so you know exactly what you are getting and the price does not change after work starts.
Drainage work done right the first time protects every dollar you put into pavement. We treat the drainage system and the pavement above it as one project, not two separate problems.
