Expansion Joint Membranes

Consistent with all open air building envelopes and designs, exterior and environmentally open seismic expansion joints must incorporate a singular or redundant water management system or seal. For the later, pre-compressed foams, zote seals, inflatable seals and de-flatable seals and or a combination thereof, are integrated as the primary water block or secondary seal for building joint covers.

Conventional membranes such as rubber bladders or neoprene membranes are also used to supplement the inherent waterproofing properties of some expansion joint covers or as a method to capture and channel out and away from a building space.

In some instances, thermoset/thermopastic single-ply membranes such as PVC, TPO, KEE and others such as CSPE (Hypalon) are used when heat weldable properties and long term performance goals are set.

Encore Building Products offers a complete line of rubber, epdm, neoprene, fabric and CSPE gutter systems in all widths and roll sizes in addition to offering  complete line of engineered waterproofing expansion membranes by Situra.

EXPANSION JOINTS

RedLINE® is a technological advancement in expansion joints replacing the technology of raised expansion joints of the last 50 years. RedLINE® has been specifically developed to waterproof expansion and control joints. RedLINE® solves the dual problem of accommodating movement (and contraction) while at the same time maintaining water tightness. RedLINE® is developed to be installed at the waterproof membrane level, this provides for a non-obstructive joint, allowing free water drainage across the joint

RedLINE® is designed for use with all types of liquid (hot or cold) e.g. asphalt/coal tar pitch mopped systems.
The following systems are most suited to RedLINE® application:

FlamLINE® is technological advancement in expansion joints replacing the technology of raised expansion joints of the last 50 years. FlamLINE has been specifically developed to waterproof expansion and control joints. FlamLINE® solves the dual problem of accommodating movement (and contraction) while at the same time maintaining water tightness. FlamLINE is developed to be installed at the waterproof membrane level, this provides for a non-obstructive joint, allowing free water drainage across the joint.

FlamLINE® is designed for use with Torched Modified Bitumen Membranes as well as Self Adhered Membranes. FlamLINE® can also be used with a two part epoxy on vertical surfaces or substrates such as metal, wood or plastic. FlamLINE® itself does NOT contain any asphalt.

 GUTTERS AND MOISTURE BARRIERS

Flexible Gutter Systems by MM Systems is a flexible fabric reinforced neoprene or EPDM gutter that satisfies the required movement criteria and compresses without damage during the full cycle of joint closure. The system collects and drains excess amounts of moisture through a drain tube that exhibits similar flexibility. The neoprene gutter is fabric reinforced to minimize material elongation due to the collection of excess moisture or debris. The under slab model provides a cost-effective solution for the remedial repair of falling systems. Either version can be used as a secondary back up to moisture protection on any expansion joint system in today’s marketplace.

FEATURES

Collects and moves water away from the expansion joint system.
Rubber gutter is fabric reinforced to minimize material elongation.
+100% movement capability.
Cost-effective solution for remedial repair of leaking expansion joint systems.
Installed in blockouts or underslab conditions.

Burke CSPE Moisture Barriers and Gutter Systems

Burke has been providing high-performance rubber products for construction and industry for more than 55 years. As pioneers in the manufacture of high-performance flexible membrane materials for more than 20 years, DuPont Performance Elastomers and Burke have been working to refine the use of Hypalon® based flexible membranes for use in a broad range of applications and weather conditions. Roofs completed with Hypalon® in 1970 are still providing excellent leak proof performance and show no sign of deterioration or need of repair.
