Why Are Drainage Systems Necessary?

Every year sinking foundations, cracked and buckled foundation walls, and cracked and uneven floors affect millions of homeowners in southern California.

Buildings located on unstable soil will settle when the foundation is subjected to moisture or poor drainage. A shifting foundation may result in structural damage and a potential decrease in the value of your investment.

If you are experiencing any of these issues:

  • Buckled hardwood floors

  • Excess water around plants

  • Flooded basement or crawl space area 

  • Mold or moisture damage in crawl spaces

  • Standing water in your lawn or vegetation areas

  • Excess water in the foundation or basement walls

  • Musty odors in living areas

  • High humidity in living areas

  • Condensation on insulation or water pipes

  • Excess water from driveway runs off into garage

  • Excess water from driveway runs off into garage

  • Condensation on air conditioning ductwork or equipment

To Avoid These Issues, We Offer Professional Solutions:



Excess water damage to foundation and basement walls


Underground Downspout Extension guides water away from the foundation by connecting downspout into an underground 4″ PVC pipe and discharge to a Flo-Well



Excess water harms plants, water is pooling in a planter


Catch Basin and Atrium Grates Protects plants by removing excess water from plants through a catch basin or an atrium grate and connecting into a Flo-Well



Water from the driveway enters the garage


Channel Drains and Grates collect sheets of water moving across driveways and sidewalks and into a channel drain prior to entering the garage.

French Drains

These divert stormwater away from your building’s foundation and can be installed in any area on your property that collects water. French drains are constructed with a perforated pipe, then gravel and filter fabric surround the pipe, similar to foundation drain systems.

Rounded Grates

Rounded Grates are often used in landscape areas, planter beds, window wells, or where debris like mulch and leaves might clog a flat grate. These grates are engineered to fit various sewer and drain pipes and fittings.

Pop Up Emitters

Pop-Up drainage Emitters act as the discharge point of a drainage system, opening easily when needed to allow water to flow freely from the pipe and away from structural foundations. The patented spring-loaded cap opens with the hydrostatic pressure of water flowing through the drain pipe, then closes as the flow subsides.


The Flo-Well is a sustainable solution for stormwater runoff. Used independently or as part of a larger stormwater management system, these units collect, retain, and discharge stormwater on-site, serving as gravel-free alternative to a traditional dry well. Units are modular and can be connected in series or stacked to meet a variety of project needs.

Catch Basins

Catch basins connect to storm drainpipes. These plastic or metal structures (either round or rectangular) with metal grates on top capture debris that can clog pipes in a drain system.

Atrium Grates

Atrium grates are most frequently used in landscape areas, planter beds, window wells, or where debris like mulch and leaves might clog a flat grate.  Choose from our wide selection of round, square, poly, or brass atrium grates.

Trench Drains/Channel Drains

Trench drains capture stormwater flowing over a larger area like a driveway, and convey rainwater to the City’s storm drain system. These garden drains are best for areas such as: Patios, Garden edges, and Garden drainage, Courtyards and Pedestrian uses

Sump Pump

Sump Pumps are a homeowner’s first line of defense against water accumulation in a basement or crawlspace areas.

Proper Soil Grading

Grading helps to channel water away from the building. Irrigation sprinklers should be pointed away from foundation walls
