Visqueen Ultimate VOC Blok Is For

Visqueen Ultimate VOC Blok is suitable for use in all types of buildings to prevent the ingress of harmful levels of volatile organic compounds (VOCs).

The barrier can be positioned above or below a solid concrete ground floor slab or above a precast suspended segmental ground floor system, e.g. beam and block floor. The barrier can also be used in all types of buildings to prevent the ingress of harmful levels of ground gases e.g.methane, carbon dioxide and radon.

The Ultimate VOC Blok barrier also acts as a damp proof membrane.

How to use/install the Visqueen Ultimate VOC Blok

  1. Visqueen Ultimate VOC Blok should be installed on a smooth continuous surface e.g. grouted beam and block floor, a compacted blinding layer e.g. 50mm thick sand blinding, or smooth concrete blinding.
  2. The substrate should be free from irregularities such as voids or protrusions.
  3. The VOC barrier can be cut with a sharp retractable safety knife or robust scissors.
  4. Lay loose on the substrate with the grey side up.
  5. The barrier should be clean and dry at the time of jointing. It should be overlapped by at least 150mm, bonded with Visqueen Ultimate Double Sided Jointing Tape and sealed with Visqueen Ultimate GR Lap Tape.
  6. Alternatively, lap joints can be heat welded to achieve an effective seal.
  7. Airtight seals should be formed around all service entry points. Visqueen Ultimate Preformed Top Hat Units should be used for sealing service entry pipes. The base of the top hat and the upstand should be bonded using Visqueen Ultimate Double Sided Jointing Tape and sealed with Visqueen Ultimate GR Lap Tape. The upstand should be secured with the supplied jubilee clip.
  8. Forming an effective barrier to gases may give rise to complex three-dimensional detailing where it is recommended Visqueen Ultimate Preformed Units are used e.g. corners. Alternatively, Visqueen Pro Detailing Strip can be used to seal awkward junctions.
  9. If the barrier is punctured or perforated a patch of the same material should be lapped at least 150mm beyond the limits of the puncture and bonded with Visqueen Ultimate Double Sided Jointing Tape and sealed with Visqueen Ultimate GR Lap Tape. Alternatively, a patch can be formed using Visqueen Pro Detailing Strip and lapped at least 150mm beyond the extents of the puncture.
  10. Due to the robust nature of the product, in normal service conditions, the barrier does not require covering with a protective layer. However, care should still be taken to ensure that the membrane is not punctured, stretched or displaced when applying a screed or final floor covering. A minimum thickness of 50mm screed is recommended. When reinforced concrete is to be laid over the barrier the wire reinforcements and spacers must be prevented from puncturing the barrier. Where there is a high risk of potential damage, the barrier should be covered with Visqueen TreadGUARD protection, screed, or other approved protection material before positioning the reinforcement.
  11. In high-temperature conditions, the membrane should be covered immediately after installation.
