VOLTEX® DS

Bentonite-Geotextile Waterproofing With Integrated Polyethylene Liner.

All the benefits of VOLTEX, plus added protection. The Voltex DS composite is comprised of two high strength geotextiles making it suitable for projects that require more durability or additional chemical resistance. Its composite construction resists damage from tradesman installing reinforcing steel over it and inclement weather. With the durability of the needle-punched composite and the ability to self-heal, VOLTEX DS offers major construction advantages over adhered sheet membrane and fluid applied waterproofing.

Exceptional Waterproofing Performance:

Protection from Water Ingress:

  • Can self-seal small cracks while forming watertight laps at the seams.
  • Provides a strong mechanical bond to poured concrete.
  • Proven effective in structures under continuous or intermittent hydrostatic pressure—up to 70m (231 ft).

Protection from Contaminants:

  • VOLTEX DS is designed for projects that require additional chemical resistance, extremely low water vapor and gas permeability.

Installation Benefits and Features:

Fast and Easy:

  • Overlapping seams with mechanical fasteners eliminates installation variables in the field.
  • Its durable composite construction eliminates the need for a mud slab.

Versatility:

  • Can be installed in virtually any weather condition, including freezing temperatures and damp conditions.
  • Can be installed on green concrete without primers or adhesives.
  • Proven effective in both vertical and horizontal applications—i.e., backfilled and property-line walls.

ENVIROSHEET

A self-adhering composite sheet waterproofing membrane, ENVIROSHEET consists of 56-mils of rubberized asphalt and a 4-mil cross-laminated, polyethylene carrier film. The two components are laminated together to produce an extremely tough waterproofing barrier.

VOLTEX®

Voltex® is a proven waterproofing membrane ideal for vertical and horizontal foundation surfaces. Voltex incorporates the high-swelling and self-sealing properties of VOLCLAY® sodium bentonite to form a monolithic, low permeable membrane to protect the structure from water ingress.

VOLTEX® DS

A bentonite-geotextile waterproofing membrane with Integrated Polyethylene Liner, VOLTEX® DS is comprised of two high strength geotextiles. The two geotextiles are interlocked by a patented needle-punching process which assures a consistent application of material.

VOLTEX® DSCR

VOLTEX DSCR is a highly effective waterproofing composite of high strength geotextiles,1.10 pounds of contaminant resistant sodium bentonite per square foot, and a integrally bonded polyethylene liner. The high swelling, low permeable, contaminant resistant sodium bentonite is encapsulated between the two geotextiles.

Helios Energy Research Facility

Berkeley, CA, USA

From design development to construction, CETCO’s expertise in waterproofing was called upon to ensure that the basement, housing expensive laboratory equipment, remains dry at all times. CoreFlex’s composite system also saved the added labor of a two-membrane installation process.

Ronald McDonald House

Chicago, IL, USA

CETCO provided the complete watertight green roof assembly for the nation’s largest Ronald McDonald House. Protected by CETCO’s COREFLEX® waterproofing membrane, three GreenScapes assemblies—intensive, extensive, and vegetated trays—were utilized to meet a challenging landscape design.

Sandpiper Run Plaza Restoration

Pawley's Island, SC, USA

This restoration application used an extensive GreenScapes system with COREFLEX® waterproofing technology to create an ocean side lawn space for condo occupants. When used in restoration applications, CoreFlex® minimizes demolition, reduces building exposure and limits building down time.

Shady Hills Gymnasium and Parking Garage

Cambridge, MA, USA

The original spec called for ULTRASEAL below slab with a layer of VOLTEX DS installed over it to provide protection from subsequent concrete operations. However, once the dewatering of the site began, it became apparent that there would be significantly more water at a greater flow rate.

Wake Forest University Hosp. Plaza Deck Restoration

Winston-Salem, NC, USA

Restoration of the plaza deck was required for watertightness of the hospital space below and reopening of the emergency room entrance. COREFLEX was quickly installed over the leaking hot-applied rubber membrane to complete the project on time with minimal building exposure.
