Saves Time & Money

Pre-assembled 10-foot lengths of EPS aggregate and pipe eliminate the need for special arrangements such as dump trucks to haul stone and the separate handling of stone and pipe.

Built to Perform

The combination of plastic pipe and EPS results in lightness and flexibility which is advantageous in several ways. During installation, soils with clay cannot be tightly compacted at the soil/aggregate interface, thus the likelihood of failure due to low permeability is minimized.

Indestructible

EZflow drains are virtually indestructible by either live or dead loading. In very deep trenches or under high fills, the relative compressibility of the assembly as compared to the adjacent soil cause nearly all loading to be borne by the soil.

Environmentally Friendly

All materials used in the assembly are inert in the expected environment. No degradable unit materials possess comprehensive strength that withstands soil pressure.

A retaining wall drain is to relieve pressure that water may exert on the wall. EZflow 10-inch diameter units are installed at the bottom of the wall with a downward grade toward a downstream outlet. Additional 10-inch diameter aggregate units can be added for height variations.

EZflow or other suitable drainage is always required behind a retaining wall to drain rainfall which is absorbed by the ground above the wall. Subsurface drainage such as EZflow retaining wall drains need to be installed with an even downward slope toward an outlet. The minimum slope should be about 1 inch per 10 feet. This may require the use of a builder’s level and level rod. Common practice is to provide weep holes through the wall. If spacing of the weep holes is close enough, grade of the EZflow may be level. Local codes may require that retaining walls over 4' in height be designed by an engineer. Check your local codes before proceeding.

Rainwater runoff can be collected from the roof by way of guttering and stored in an EZflow drain field until it can be perked into the soil helping to restore ground water. Check with building codes for mandates.

Housing and other development increases rainfall runoff due to impervious surfaces such as roofs and pavement. Collection of roof water runoff can be piped to an underground EZflow drain field where the runoff is stored and absorbed by the surrounding soil. This prevents erosion in the nearby yard area and natural channels downstream. Multiple units of EZflow may be desirable to provide adequate storage and additional soil interface area for absorption.

Local ordinances or building codes may require that rainfall runoff not be increased due to development. This may require advice from a professional.

Barrier Cover - A barrier over or around the EZflow units may be required to prevent sand-like soils from entering the EPS aggregate. The type of barrier can be untreated building paper or filter fabric and should be selected based on site conditions. Local practices in similar applications and soils may be a guide as to the type of barrier that should be used.

EZFlow produces prefabricated drainage systems designed specifically to replace stone aggregate systems in a variety of applications.

The aggregate used in EZflow drains is recycled expanded polystyrene (EPS) the same material commonly used in products such as hot drink cups and protective packaging. Non-degradable EPS is an attractive alternative to stone for several reasons:

A foundation drain relieves water pressure that can build up around the basement walls or foundation. EZflow 10-inch diameter units are installed at the bottom of the wall with a downward grade toward a positive outlet. If the ground water elevation is high, additional 10-inch aggregate units can be added. Building codes may mandate foundation drains.

EZflow foundation drains neutralize hydrostatic pressure by disposing of approaching groundwater before it reaches subsurface walls. It provides a drainage system that collects seepage from the backfill, routing it downward and away from the structure through a drain.

Below grade structures, such as foundation walls, are particularly susceptible to the combined effects exerted by soil and water pressure. Hydrostatic or water pressure, in particular, is the primary cause of dampness, water penetration, and major distortion such as cracking. More than 60% of residential homes suffer from wet basements.

EZflow foundation drains need to be installed with an even downward slope toward an outlet. The minimum slope should be about 1 inch per 10 feet. This may require the use of a builder’s level and level rod.

Barrier Cover - A barrier over or around the EZflow units may be required to prevent sand-like soils from entering the EPS aggregate. The type of barrier can be untreated building paper or filter fabric and should be selected based on site conditions. Local practices in similar applications and soils may be a guide as to the type of barrier that should be used.

Septic Drain Fields

EZflow septic drain fields have proven to be the longest lasting, most effective drain field on the market today. Make sure your septic tank contractor is EZflow certified and ask for the EZflow septic drain field on new installations or repairs on existing systems.

The installation of EZflow drain fields and other components of a septic system are usually governed by regulation. Generally, a permit is required from the local health department. EZflow drain fields may require a greatly reduced land area that will allow for the saving of trees and other natural vegetation.

EZflow French Drains are used for dewatering soils where water saturation is at an undesired degree. Standing water, soft or muddy soil can be eliminated by installing EZflow French drains. The unwanted water is moved to a downstream outlet. EZflow 10-inch diameter units with 4-inch diameter perforated pipe are installed in a 10-inch or wider trench. The depth of the trench should be 18 inches or more and have a downward grade to a downstream outlet. To help standing surface water drain, EZflow assemblies with aggregate only can be installed above the assembly with pipe.

Subsurface drainage such as EZflow French drains need to be installed with an even downward slope toward an outlet. The minimum slope should be about one inch per 10 feet. This may require the use of a builder’s level and level rod. A barrier over, or no more than 3/4 around the EZflow units, may be required to prevent sand-like soils from entering the EPS aggregate. The type of barrier can be untreated building paper, filter fabric, newspaper, or straw and should be selected based on site conditions. Local practices in similar applications and soils may be a guide as to the type of barrier that should be used.

For the drainage of large areas, subsurface drainage can be installed in a herringbone or similar pattern. Spacing and depth of the EZflow rib pipes depends on soil type, rainfall, etc. The capacity of the spine pipe may have to be larger than the capacity of a single EZflow unit. Local practice for similar applications may be a guide. Using a professional designer should be considered if subsurface drainage is critical.

EZflow may be used under areas of light to medium surface loading. EZflow should only be used under areas of heavy surface loading, such as a parking lot, when installed at depths of more than two feet.

EZflow can be used to intercept groundwater movement toward an area where water table control is essential. Elevation must be lower than protected area. Aggregate should extend upward to intercept all moving water.

In areas of high ground water, seepage from slopes created during development may cause erosion of the slopes. EZflow interceptor drains can prevent this erosion by diverting the high ground water to a safe outlet.

Subsurface drainage, such as EZflow interceptor drainage, needs to be installed with an even downward slope toward an outlet. The minimum slope should be about 1 inch per 10 feet. This may require the use of a builder’s level and level rod. A barrier over, or no more than three-quarters around the EZflow units, may be required to prevent sand-like soils from entering the EPS aggregate. The type of barrier can be untreated building paper, filter fabric, newspaper, or straw and should be selected based on site conditions. Local practices in similar applications and soils may be a guide as to the type of barrier that should be used.

The patented EZflow gravel-less drainage system utilizes the time-proven principle used in gravel systems for golf course drainage while eliminating the problems inherent with using gravel and clogged drainpipes and mower blade damage.

Gravel can contain fines, which shorten the active life of the system. The new geo-synthetic aggregate is fine-free and offers 40% additional void space for greater water flow.

The engineered EZflow beads provide the necessary filtering of soil particles to prevent drainpipe clogging. Using the EZflow barrier fabric to cover the top of the system before adding the backfill or sand eliminates the clogging problems associated with sock pipe and extends the life of your system.

The pre-assembled 10-foot sections allow for quick and easy installation, while assuring a consistent aggregate level in the trench. Additionally, a very important feature of the EZflow system is the elimination of loose gravel on your golf course. The EZflow systems are ideal for fairway and greenside bunkers, draining wet areas around the course and for installation of drainage systems on new or rebuilt greens.

If a problem with a bunker or wet area develops on your course that could delay or interrupt play, the simple solution for a quick and lasting repair is the EZflow system. Repairs can be made in hours rather than days and there is no loose gravel to damage mower blades.
