Description
Ethylene Polypropylene Diene Terpolymer, more commonly referred to as EPDM, is a synthetic rubber that is used in a wide variety of applications ranging from roofing to automobile tires. Calendared into a sheet form, it possesses many exceptional characteristics that make it an ideal membrane for most any waterproofing application.

Lexcan EPDM membrane is available in three different types and a variety of thicknesses:

Standard EPDM:
Lexcan Standard EPDM is an unreinforced synthetic rubber sheet, available in 1.1 mm (45 mil), 1.5 mm (60 mil) and 2.3 mm (90 mil) thicknesses. The 1.5 mm thickness is the most commonly used product for waterproofing applications.

Reinforced EPDM: This product consists of an EPDM membrane internally reinforced with a polyester scrim. The scrim imparts superior tear and puncture resistance where physical abuse or vandalism might be a concern. Lexcan Reinforced EPDM membrane is available in 1.1 mm (45 mil), 1.5 mm (60 mil) and 1.9 mm (75 mil) thicknesses. 

All Lexcan EPDM membrane systems come with related accessory products to complete proper seaming, details and flashing. The result is a versatile and proven waterproofing system able to ensure long-term performance in the most demanding environments.

   

 


Uses
Lexcan EPDM is widely used in all of the following waterproofing applications:
• Below Grade Waterproofing
• Basements
• Parking Garages
• Bridges
• Plaza Decks
• Ponds & Fountains
• Water storage Tanks
• Tank Lining


Lexcan EPDM membranes are also widely used in roofing and civil engineering. For more information on these applications, refer to other sections of this website.

Features & Benefits
Exceptional Crack Bridging Ability – Substrates often spall, crack or split due to settling or thermal expansion and contraction. Most waterproofing membranes will fail when the underlying substrate cracks. In contrast, with its exceptional elasticity and flexibility, Lexcan’s EPDM rubber membrane can often accommodate a substrate failure while remaining watertight!

Consistent Membrane Thickness – Liquid applied membranes may vary in thickness depending on local high and low spots in the substrate. Factory manufactured EPDM membrane on the other hand ensures a consistent membrane thickness throughout the application.

Highly Flexible – Fully flexible down to -60°C, Lexcan EPDM far exceeds the cold temperature flexibility of other waterproofing membranes!

Proven Longevity – Lexcan EPDM has been in use over 40 years around the world, in climates ranging from the high artic to the deserts of Algeria. Our earliest projects are still performing superbly!

Large Sheet Sizes – Lexcan EPDM membranes are available in a wide variety of sheet sizes,* from 1.52 m x 15.24 m (5’ x 50’) all the way up to 15.24 m x 60.96 m (50’ x 200’)! Large areas can be quickly and efficiently waterproofed in a fraction of the time of other systems!

Suitable for Direct Exposure – Unlike most traditional waterproofing membranes, Lexcan EPDM is completely resistant to sunlight and UV radiation. There is no need to protect the waterproofing membrane from sunlight either during construction or after!

Cold Application – Lexcan’s W-A Design is entirely cold applied. There are no fire or liability concerns as with torch applied systems.

*: Available sheet sizes vary depending on type and thickness of membrane.

Waterproofing Systems
DESIGN W-A: ADHESIVE ADHERED EPDM WATERPROOFING
In this application, a Standard or Reinforced EPDM membrane is fully adhered to the substrate using a Bonding Adhesive. The substrate may be concrete, masonry, wood, most metals and some types of insulation. Substrates must be dry, structurally sound and free of moisture, chemical release agents, greases, dirt, debris and dust. Lexcan has both a solvent based and a water based adhesive that may be used for this application.
