Posted by The Plastic Sheeting Gurus! on Mon, Aug 08, 2016 @ 01:44

Enkadrain Family of Drainage Products

Enkadrain is a proven drainage products that has been used worldwide for over 25 years in a myriad of applications. It got its first job in Europe More than 25 years ago successfully draining soil and offering hydrostatic pressure relief.

Over the years, the Enkadrain product line has grown to meet the demands of the rapidly changing construction market. As building designs have become more complex, architects and engineers have been called upon to work more creatively with materials that add value and save resources. Always innovative and on the cutting edge of technology, Colbond Building Products has now added a complete line of geocomposite drains made from recycled polymers that contribute to the LEED program.

Let's explore some of the areas that Enkadrain excels.

Enkadrain for Planters and Plaza Decks

Enkadrain offers excellent drainage for planters and plaza decks. By replacing gravel, it reduces weight and increases soil area for a healthier root mass.

Enkadrain 3000R Series products are a new generation of the Enkadrain family. These new drainage composites are made of a post-industrial recycled polypropylene drainage core of fused, entangled filaments and a geocomposite fabric bonded to one or two sides. These products can contribute up to 2 LEED points when used in conjunction with other recycled content products.

A family of three-dimensional, multilayer drainage products consisting of a core of fused, entangled filaments and one or two nonwoven geotextile fabrics attached. Designed to relieve hydrostatic pressure from soils abutting below grade structures, Enkadrain provides a lightweight alternative to traditional sand and gravel drains. The geotextile filter fabric allows water to pass through to the polymeric core as it retains the surrounding soil. Ground water is then channeled through the Enkadrain core to a perforated pipe, weep hole or other discharge system before it ever reaches subsurface walls - keeping the structure dry.

Where Will You Find Enkadrain Products?

  • Foundations & Retaining Walls
  • Commercial Building
  • Insulated Concrete Forms
  • Planters Plaza Deck
  • Beneath Slabs
  • Underground Parking

What Are The Differences Between The Enkadrain Products?

Drain Flow (gal.min/ft):

When comparing Enkadrain 3611R, 3615R, and 3811R, regardless of the soil seepage (gal.min/ft)  or the backfill depth (10 ft to 40 ft), Enkadrain 3611R has the largest drain flow (gal.min/ft) value whether it's silty sand with a K value of .33, Clayey San K value of .42, or Sandy Clay K value of .56.  Enkadrain 3811R has the least amount of drain flow.

Sloped Green Roof Gradients:

For a Flat <1° (<2%) roof gradient, Enkadrain 90118, 9120, and 9125 are recommended.

For a Low 1-5° (2-9% ) roof gradient, Enkadrain 9010, 3611, 3615, 3811 and EnkaRetain&Drain 3111 and EnkaRetain&Drain 3211 are recommended.

For a Steep 5-20° (9-36%) roof gradient, Enkadrain 3610, 3801, 7910,  EnkaRetain&Drain 3111 and EnkaRetain&Drain 3211 are recommended.

For a Very Steep >20° (>36%) roof gradient, Enkadrain 3601, 3801 and 7910 are recommended.

Common Questions and Solutions:

Question:  For roofs that have ponding water which can cause plant distress, which Enkadrain should be used?

Answer: Enkadrain 9118, Enkadrain 9120, and Enkadrain 9125 will lift the growing plants above the ponding water.

Question:  The roof has sufficient fall to the drain, but we need drainage to convey rounoff to roof drains. What do you recommend?

Answer:  Enkadrain 9010, Enkadrain 3611, Enkadrain 3615, Enkadrain 3811 or Enkadrain 3811 will move the water.  If you need the drains to offer high water storage capacity, EnkaRetain&Drain 3111, or EnkaRetain&Drain 3211 will do the job.


Question:  The water on the roof runs off too quickly on steep slope, thus the growing substrate can become dry especially near the top of the roof.

Answer:  If you need to slow down the runoff and allow time for the rain to saok into the grwoing substrate, use Enkadrain 3601, Enkadrain 3801, or Enkadrain 7910.  If you need to retain the water and compensate for the higher runoff, then use either EnkaRetain&Drain 3111, or EnkaRetain&Drain 3211.

Question:  The roof has and exceedingly steep gradient and thus a very high runoff. We risk the green roof materials sliding off.

Answer:  Enkadrain 3601, Enkadrain 3801, or Enkadrain 7910.

Erosion Control and Turf Reinforcement Mats

Posted by The Plastic Sheeting Gurus! on Thu, Aug 04, 2016 @ 10:03

Turf Reinforcement Mats

Turf reinforcement mats offer erosion protection and control to hill sides.  They help the newly planted vegetation take root in the presence of flowing water. Water exerts extreme force on plants and can thus up-root them in its path.  

When it comes to tensile strength, how much is considered enough? The lack of standardized test protocol and lack of standardized specifications for Turf Reinforcement Mats (TRM’s) have led to much confusion in the marketplace. One particular point of confusion lies in the question of how much tensile strength is required of a turf reinforcement mat to provide satisfactory performance? 

Channel Linings:

For Channel Linings, there are two widely accepted methodologies that allow the designer to examine the permissible velocity or permissible tractive (shear) force to determine the suitability of a given lining. For slope design, some form of the Universal Soil Loss Equation (USLE) is commonly used. It is important to point out that Tensile Strength is not used in any of these design methods.

A secondary consideration of tensile requirement of TRM’s depends on the severity of the exposure, primarily related to the depth of flow and the topography, as well as on how frequently the TRM is anchored to the ground surface. The most severe case would involve deep flow within a steep channel with infrequent anchoring of the TRM. Conversely, TRM installations exposed only to rainfall impact and sheet runoff on slopes of modest steepness would require minimal tensile strength.

Turf Reinforcement Mats Installation Stresses:

But what about installation stresses? Generally the greatest tensile stresses that TRM’s are exposed to occur during installation. The deployment, edge burial, pinning or stapling, and soil covering (if required) of the TRM may involve pulling on it, walking on it, pounding on it, driving on it, dumping on it, and/or compacting on it. These imposed forces are usually nominal, but they may be important to consider if the installer is inexperienced or careless.

Tension Resulting from Anchorage

The imposed shear will be resisted either by anchorage at points (i.e. pins or staples) or by anchorage in trenches. [The general usage of anchoring devices such as pins or staples is intended as a temporary means of securely fastening the TRM to the soil to ensure intimate contact between the TRM and the soil until vegetation is established. While anchor trenches are permanent and the pins or staples are temporary, it is prudent to assume these devices will contribute some tensile resistance.] These anchorages prevent the TRM from moving with the flow through developing tension in the TRM. The magnitude of the tension can be determined using Equation 1 and multiplying by the contributory area.

Tension Resulting from Anchorage

Calculation of tension resulting from point anchorage. The total required tension to be resisted by each anchorage point can be determined by multiplying the required tension by the contributory area for each anchorage. The contributory area is determined by anchorage spacing. Calculation of tension resulting from trench anchorage. The total required tension to be resisted by an anchor trench can be determined by multiplying the required tension by the contributory area. The contributory area is the unanchored length of TRM below the trench.

Haunted House Black Plastic- What's Best?

Black Plastic For Halloween- What's the best choice? 

OK, so you need some black plastic to make your haunted house in your garage, or at your school. The first thought might be to run to a big box store and grab the cheapest black plastic they have.  That black plastic will create the effect you want and darken the room or space you plan to use for your haunted house. BUT....you really want to get fire retardant/ fire resistant black plastic for a little bit more.  Now I know nothing will probably not happen in terms of a fire, BUT if a spark or flame should hit that regular black plastic, in seconds that stuff will go up in flames, and put off so much smoke! Watch this video (click here) and see what happens when a flame is put under regular plastic versus fire retardant plastic.Fire_Retardant_plastic_protects.png

This is a question that pops up every year as the witching hour approaches, and all the little ghosts and goblins will be running about. The answer is NO. For Halloween Haunts you want to use a Fire Retardant plastic. You see, in most jurisdictions the fire marshals are now making haunted houses use fire retardant products, like drywall, or plastic sheeting (polyethylene) that is Fire Retardant.  Many haunted houses have been made to install basic walls in recent years, because their fire marshals insisted they were necessary for meeting the fire safety requirements, and did not know there were far less expensive options available. 

 haunted house black plastic fire retardant

Global Plastic Sheeting supplies Black FR Polyethylene that  fire marshal's approves for this application. It is used in large amusement parks as well as for school and home owners. This polyethylene has been chemically altered when it was extruded, so it can no longer contribute significantly as a fuel source in the event of a fire.  This product provides a very low cost option for making your haunted attractions meet the local codes. Best of all we will provide you with the certifications to prove you are using FR Plastic.

Don't let those precious little "monsters" burn your house down by using plastic sheeting that is not fire retardant!

Most fire marshals are looking for products that pass the NFPA 701-15 Test 1, and/or the CA Fire Marshal Title 19 fire standards.  One should always check with fire authorities in their jurisdiction before erecting any haunted attraction.

Plastic Sheeting 101

Plastic & Plastic Sheeting 101 

Plastic is the common name for a wide range of synthetic materials made from petrochemicals.  Plastic has had a big role in building materials due to some of its properties. Here are a fraction of the advantages:
  • Parts made from plastic are strong yet lightweight. They are easy to maneuver and put to use.
  • Hard plastic has excellent weather ability. It is durable, knock-and-scratch resistant.  Flexible plastic sheeting on the other hand does not weather well at all unless it has a U.V. additive added to the formulation to allow it to withstand the U.V. from the sun and atmosphere.
  • Hard plastic such as HDPE does not rot or corrode.
  • Plastic is remarkable in the fact that it has limitless possibilities in design achived by extrusion, bending and molding.  When plastic is made into its flexible form, plastic sheeting has countless applications it assists.
  • Plastic both hard and in the flexible form can be sewn and nailed.
  • Plastic can be recycled.
  • It is a poor conductor of electricity.

Products Made Of Plastic in the Construction Industry:

  • Insulation materials: PVC sheets, insulating membranes.
  • Pipes  : Electrical Conduits, Rain Water & Sewage pipes, Plumbing, Gas Distributions.
  • Cables : PVC Insulation on cables, Insulation Tapes .
  • Flooring : Flooring tiles & Rolls .
  • Domes / sky lights : Opaque as well as transparent.
  • Roofing  : colored or Double skinned for insulation.
  • Windows & doors : Extruded sections for Door and windows and panels.
 
In its simplest terms, the main difference between the different types of plastic is the way their cellular structure, or mol ecules bond with each other, and how tightly they are formed.

1) Low Density Polyethylene (LDPE), most common type of plastic sheeting, very flexible, most often from 0.5 mil thick to about 40 mil in flexible sheeting forms. Good conformability to surfaces. Because the cell structure is not as strong or dense as some other types of plastic sheeting, it is not typically as strong or puncture resistant as other forms or blends, but has thousands of common uses. Widely used for everything from construction and agricultural sheeting (often called Visqueen), Engineered Plastic Sheeting of countless types for such things as Vapor Retarders (also called Vapor Barriers by many), Surface Protection films, Pond and Canal Liners, Covers, Tarps, Abatement Plastic, Containment, packaging, and the list goes on.

2) Linear Low Density Polyethylene (LLDPE), blended form of LDPE where the film has much more flexibility, tensile strength, and more conformability. LLDPE is "softer" and more pliable, so is an excellent choice for such things as pond liners, or blended into other films to give them extra strength and flexibility. This is perfect for an application like a self-adhesive carpet protection film, where the film needs to have an amazing amount of strength in a very thin film to absorb impacts, but not tear or puncture. In this form of poly, the molecules all line up and strongly hold together as the film is stretched to give the structure much more strength and elongation than LDPE. Most common in thicknesses ranging from 0.5 mil to 40 mil in flexible plastic sheeting.

3) Medium Density Polyethylene (MDPE), the least commonly used form of polyethylene for flexible plastic sheeting. Has more strength than LDPE, a little more chemical resistance, tighter cell structure, more puncture and tear resistance. Often blended with LDPE and or LLDPE to give the attributes one is looking for in a particular type of film. For instance, many pond liners have MDPE to add some strength and toughness, without adding too much stiffness.

4) High Density Polyethylene (HDPE, aka HD), widely used for many applications. HDPE is the strongest, toughest, most chemical resistant, and least flexible of these four types of polyethylene. It also has the most UV resistance of the bunch without additive packages to increase this attribute. HDPE has a very tight cell structure, making it very difficult for other molecules to pass through its structure on a microscopic level. HDPE is the most easily field seamed of these products, and is generally used on an industrial level in thicknesses from about 12 mil to 100 mil thick. Most golf course ponds are lined with HDPE, most industrial ponds and canal liners, secondary containment liners, root barriers, many applications where chemical resistance is needed. This is also used in thousands or maybe millions of applications in thinner forms, especially in blends with the other types of polyethylene, because the HDPE adds much strength and toughness with its very tight bonds with other molecules.

The density of polyethylene is measured in a column of water, and they are all classified depending on ranges of density. LDPE (and LLDPE) are generally within the range of 0.919-0.924 g/cm³. MDPE are generally within the range of 0.926-0.940 g/cm³. HDPE are generally within the range of 0.941-0.965 g/cm³. These numbers can vary slightly depending on your source, and are not set in stone, just general guidelines.
