Kemperol V210 Roof Waterproofing System

Manufacturer: Kemper System Ltd 

Materials: Flexible Polyesters 

The Kemperol V210 Roof Waterproofing System is a cold liquid-applied, unsaturated polyester coating, reinforced with a 165 g·m–2 embedded polyester fleece to provide a waterproofing membrane with a minimum dry film thickness of 2 mm and typical cured mass of 3.165 Kg·m–2

The system components are:

  • Kemperol V210 — available in two packaging options, a three part V210 system or a two part V210(M) system:
    Kemperol V210
    o Component A — Kemperol V210 Basic Resin
    o Component B — Kemperol V210 Accelerated Resin, containing the required proportion of accelerant
    o Component C — CP Catalyst Powder
    Kemperol V210 M
    o Component M — Kemperol V210 Basic Resin plus Kemperol V210 Accelerated Resin, containing the
    required proportion of accelerant
    o Component C — CP Catalyst Powder
  • Kemperol 165 Fleece — polyester fleece for embedding into Kemperol V210 resin to act as reinforcement. The fleece has nominal characteristics of:
    – weight per unit area (g·m–2) 165 ± 10%
    – tensile strength (N·50 mm–1) ≥ 250
    – elongation at break (%) ≥ 40
    – roll length (m) 50
    – roll width (mm) 105, 210, 262.5, 350, 525, 700 and 1050

(1) The Certificate holder should be consulted for specific advice on board facing compatibility


25 Years 

With adequate maintenance and repair, the system will have a service life of at least 25 years.

Installation Requirements

Installation of the system must only be carried out by installers trained and approved by the Certificate holder.

Puncture Resistance

P1 - non accessible

Least compressible (eg concrete)

P4 - roof gardens, inverted roofs and green roofs)

Most Compressible Substrate (eg insulation)

Fire Safety

A 19 mm thick plywood deck covered with the system to a thickness of 2 to 2.5 mm will be unrestricted under the national Building Regulations.

The designation of other specifications should be confirmed by: England and Wales — test or assessment in accordance with Approved Document B (Volumes 1 and 2), Appendix A, clause A1, Scotland — test to conform to Mandatory Standard 2.8, clause 2.8.1, Northern Ireland — test or assessment by UKAS-accredited laboratory, or an independent consultant with appropriate experience.
