ACO Slab Drains: Applications, Benefits & Installation of Trench Drains

Introduction to ACO Slab Drains

ACO slab drains are an efficient drainage solution used in a variety of commercial, industrial and residential settings. Installing proper drainage is crucial for directing water away from buildings and preventing flooding, slip hazards from wet areas, foundation damage, landscape erosion and more.

What are ACO Slab Drains?

ACO slab drains are linear trench drains that sit flush with the finished floor level. Also sometimes called channel drains or line drains, they typically consist of a sloped V-shaped or U-shaped channel covered by a removable grate. The channel conveys water through the drain body to a discharge point, removing it quickly and efficiently from the surrounding floor area.

Benefits of ACO Slab Drains

There are several key benefits that make ACO slab drains a smart choice:

• Sit flush with the floor for an even surface that maintains accessibility.
• High flow capacity rapidly directs water away from flooded areas.
• Durable stainless steel and polymer construction stands up to heavy traffic.
• Modular design allows customization of drain length as needed.
• Easy to clean by simply lifting out the grate.

Common Applications of ACO Slab Drains

ACO slab drains have very versatile applications across many sectors. Some of the most common uses include:

Commercial Kitchens

Sanitation is paramount in commercial kitchen settings. ACO slab drains efficiently remove high volumes of wastewater from dishwashing stations, sink areas, and floor cleaning. Their high capacity keeps water from pooling and allows for thorough cleaning.

Parking Garages

Parking garages allow lots of water, oils, and chemicals to accumulate on the floor from cars. ACO slab drains along traffic lanes, ramps, and low points provide an important defense against hydroplaning hazards and corrosion from standing liquids.

Patio Areas

Outdoor living spaces like pools, patios, and decks often adjoin the home. ACO line drains installed subtly around the perimeter provide drainage that protects the foundation and prevents slick surfaces that could cause falls.

Choosing the Best ACO Slab Drain

With different sizes, grate options, and materials available, it's important to select the right ACO slab drain model for your specific application. Here are some key considerations when choosing:

Drain Location

Consider existing drainage patterns on the site along with areas where water accumulates. Locate drains appropriately to capture runoff. Follow manufacturer's guidelines for slope and placement.

Drain Capacity

Determine the expected volume of water that could accumulate, such as from heavy rain or a pipe burst. Choose a drain width and material that provides adequate flow rates for the intensity of drainage needed.

Traffic Load

Will the drain be located in an area with heavy vehicle loading or only periodic foot traffic? Heavy duty ductile iron grates are best for abusive traffic conditions, while lighter stainless steel or polymer grates suffice for lower intensity loads.

Surface Type

Select grate patterns and openings that best suit the floor or surface material. Heavier gratings typically work for concrete flooring. Multi-directional grates allow debris flush through. Smaller mesh grates fit well with pavers or tile.

Installing ACO Slab Drains

While seeming simple, proper installation of trench drains ensures they work effectively for years to come. Here is an overview of key steps:

Layout

Map out drain section placement and mark their slope elevation. For optimal flow, trench drains should slope at 0.5%-2% grade towards the outlet. Make adjustments for any low spots or problem areas.

Excavation

Dig a trench at least 6 inches below the drain channel depth to allow for gravel and drain sections. The trench width depends on the overall drain width and installation method. Maintain the marked slope grade.

Base Preparation

Fill the trench with a 3-4 inch gravel base, compacted in layers, to support the drain sections. The base should remain below the desired slope height for the drain channel. A concrete foundation can also support trench drain sections.

Drain Assembly

Lock the modular trench drain sections together per manufacturer specifications to achieve the desired overall length. The outlet end of the drain should feed to a catch basin, pipe network, or desired discharge point.

Grate Installation

With sections fully assembled, lower them into the trench and confirm alignment to specifications. Insert grates or covers into the channel opening to complete basic installation. Backfill and compact soil alongside the drain trench.

Be sure to follow all local codes and permit requirements for proper slab drain implementation. While appearing basic on the surface, attention to key details makes all the difference in achieving a fully functional system.

FAQs

What types of grates are available for ACO trench drains?

ACO offers steel, stainless steel, and polymer grates. Steel and stainless steel options feature different mesh sizes and directional designs. Polymer grates can provide improved aesthetics. The type of traffic and surface material help determine the best grate choice.

Can I install an ACO slab drain myself?

ACO slab drains allow convenient DIY installation in many cases. Key aspects involve proper trench sizing and slope, gravel base preparation, assembling sections, and backfilling. Follow all instructions and ensure proper connections to drainage networks or outlets.

How often do I need to maintain or clean an ACO trench drain?

ACO slab drains feature removable grates, allowing simple access for inspection, debris removal, and flushing out the channel with water or cleaning solutions. Frequency depends on conditions, but checking drains every 2-3 months is recommended. Keeping grates and the drain line clear maximizes flow.

What slope should an ACO linear drain have?

ACO recommends a 0.5%-2% slope grade for optimal drainage capacity. The exact slope depends on the drain length. Greater slopes over short runs can increase water velocity and discharge rate. Use the manufacturer's drain sizing guidelines to determine the ideal slope.
