At the end of this program, participants will be able to:

• Discuss the evolution of surface methods of drainage

• Evaluate the functional features of u-shaped, single-slotted, non-grated trench drain systems and compare them to those of other trench drain systems

• Identify trench drain system components

• Describe design considerations and installation requirements

Learning Objectives

of 30 ©2010

As construction materials evolved, simple ditches gave way to cast-in-place, pre-cast concrete, corrugated slot

drains, polymer concrete trenches, fiberglass trench drains, pre-engineered HDPE, and LLDPE grated slot

drains

Brief History of Drainage Surface & Floor Methods of Drainage

of 30 ©2010

Traditional Trench DrainsSurface & Floor Methods of Drainage

• Cast-in-place

• Pre-cast concrete

• Slotted

• Pre-engineered

of 30 ©2010

• Single slot-style mouth on top of a formed, u-shaped base

• No grate required

• Low maintenance

• Sanitary

• Cost effective

Non-Grated, U-Shaped, Single-Slotted Drains Surface & Floor Methods of Drainage

of 30 ©2010

• Fiberglass

• HDPE (high-density polyethylene)

• Stainless steel and galvanized metal

Drain MaterialsSurface & Floor Methods of Drainage

of 30 ©2010

• Grated, u-shaped drains average $60-70 per lineal foot (include replacement grates at $15-20 per lineal foot)

• Galvanized u-shaped, single-slotted, non-grated drains average $40 per lineal foot

Cost Comparison Surface & Floor Methods of Drainage

of 30 ©2010

• One straight channel with a single slot profile blends neatly with surrounding surface materials

• Clean, crisp lines make it suitable for a variety of applications

Aesthetics Functions & Features

of 30 ©2010

• Pre-engineered slope makes it a self-cleaning system

• Can be cleaning manually using:– drain cleaning paddle– custom flush valve– pressure washer

CleaningFunctions & Features

Test results, as determined by the Faculty of Engineering(civil engineering department) at the University of Manitoba

• The computed flow capacity of a 1” (commercial) slot opening was 0.040 ft/s or 18 gallons per minute (per foot of slot)

• The computed flow capacity of a½” (residential) slot openingwas 0.026 ft/s or 11.4 gallons per minute (per foot of slot)

FlowFunctions & Features

of 30 ©2010

• Structural capabilities are in direct relation to the strength of the surrounding concrete

• Weight load is channeled through the u-shaped drain and into the concrete floor

Structural CapabilitiesFunctions & Features

of 30 ©2010

• Used in facilities with stringent sanitary regulations (food and beverage industry)

• Durable, easy to clean

• No grates – no components that break

• Machine placement is not limited by drain placement

DurabilityFunctions & Features

of 30 ©2010

• Car washes, Car dealerships• Food processing plants• Farm shops• Parking lots• Airport tarmacs• Municipal buildings• Ambulance bays• Aircraft hangars• Gas stations• Fire halls• Any area requiring drainage

OverviewApplications

of 30 ©2010

A commercial grade system may be available as 16-gauge, hot dipped galvanized or stainless steel, in three meter (3m = 9’ 10”) sections that are pre-sloped .05% (½”)

Commercial ApplicationsApplications

of 30 ©2010

Example: Commercial Application Applications

of 30 ©2010

• Rebar tie-ins• Leveling brackets• Flush valves

Commercial System FeaturesApplications

of 30 ©2010

• Sump pit alternatives

• Sump pits


of 30 ©2010

• Sump pits– single inlets– silt baskets– lids

• Sump pits– "L" flange– duel inlet

• Oil separator pits

of 30 ©2010

• Components of drain system arrive at the site in sections, factory-ready, for bolting together

Factory-ReadyInstallation

of 30 ©2010

New Drain, Existing Floors• Mark out desired location of new drain and remove

existing drain• Follow steps for a new installation – dowel into either

side of exposed slab

Replace Existing Drain System• Remove grates and walls of existing trench drain, and

follow steps for a new installation• If existing drain walls cannot be removed, and the

existing trench is deep enough, place new drain inside the trench, secure to desired level, and pour into place

RetrofittingInstallation

of 30 ©2010

• Single channel provides efficient drainage

• Aesthetically pleasing

• Sanitary and durable

• Easy to install and maintain

• Meets structural load-bearing requirements for even heavy traffic applications
