Free shipping included Overview
| 650 PRM - Puncture Resistant Membrane - is a strong, self-adhering, 65-mil, post-concrete pour sheet waterproofing membrane/vapor retarder with a double thick, high-strength, co-extruded backing laminated to a thick layer of rubberized asphalt compound. 650 PRM adheres tightly and permanently to concrete. The backing forms a continuous barrier to water and moisture vapor entry. 650 PRM can be used in both horizontal and vertical applications. VERTICAL APPLICATION: 650 PRM can be used in wall applications when applied to the exterior side of vertical concrete foundation walls, tunnels, and related applications where waterproofing is critical. It allows for faster waterproofing applications by eliminating the step to install an additional protection course prior to backfilling with clean fill. HORIZONTAL APPLICATION: 650 PRM can be applied to horizontal slab applications such as parking garages, plaza decks, plywood decks and related applications and allows for concrete topping slab installation without the need for a separate protection course in most situations. |

Features & Benefits
Strong, self-adhering sheet membrane with a thick, high strength, tough co-extruded backing.
Outstanding Puncture Resistance: 2 times higher than the new AC 527 requirement - Better protection against backfill damage.
Superior Joints: Strong laps seams create a long lasting, water tight system - Outperforms the new AC 527 standard (ASTM 1876) by more than 150%.
Allows for faster waterproofing applications by eliminating the step to install an additional protection course prior to backfilling when using clean fill.
HORIZONTAL – designed for application to horizontal slabs such as parking garages, plaza decks, plywood decks, and related applications where waterproofing is critical.
VERTICAL – designed for application to the exterior sides of vertical concrete foundation walls, tunnels, and related applications where waterproofing is critical.
The 650 PRM can be utilized in the Dual Core System that capitalizes on both the advantages of a fluid-applied and sheet-applied membrane in a single system.
Jobsite Adaptability: Flexible material that adapts to job site irregularities for ease of installation.
