System III • Air Barrier - Above Grade Cavity Walls

A SYSTEMIZED APPROACH TO MOISTURE PROTECTION

Features

• Excellent air vapor and moisture control through high performance monolithic membrane.

• System versatility – Ecoflex can be applied to a wide range of substrates (concrete, CMU, block, ICF, wood, dense glass, etc.) on the positive or negative side.

• Cost effective – The material costs and installation speed make this a high value, quality and performance solution.

• No seam failures – The highly flexible spray applied or fluid applied monolithic membrane bonds tenaciously to almost any substrate and in almost any condition including green concrete and damp block.

• Problem prevention – Along with its excellent elongation and recovery properties, Ecoflex is self sealing thus, preventing any air leakage due to minor penetrations and cracking caused by building movement and shrinkage.
The Components:

DETAIL MEMBRANE
ECOFLEX-F

A self adhering 40-mil sheet membrane used to detail around openings, plane changes, penetrations and cracks.

For best results use Epro Primer to prepare substrate prior to installation.

FIELD MEMBRANE
ECOFLEX-S or R

A spray or fluid applied, exceptionally flexible, monolithic membrane.

OPTIONAL DETAIL MEMBRANE
ECOLINE-R

With polyester reinforcement fabric may also be used to detail around openings, plane changes, penetrations and cracks.




The Installation Steps:

Step 1-Detailing
• Treat all cold joints, substrate changes, penetrations, door and window openings with self adhering Ecoflex-F or Ecoflex-R and polyester mesh.

Step 2-Air Barrier Membrane
• Begin the application of ECOFLEX-S from the bottom to the top. Always applying to the footer first.

*Spray application should be done in 4 ft. x 4 ft. passes to a 20-mil build on each pass.

Step 2 – OPTIONAL Air Barrier Membrane
• ECOFLEX-R may be applied by roller, brush or sprayer to a 40-mil build. Apply two 30-mil coats to achieve a 40-mil finish coat.

Step 4 – Drainage Course
• Start from top of structure and attach ECODRAIN-E to the roof and working down the walls to the footer. Secure the drainage mat at 90 degree, transitions and overlaps with appropriate fasteners.
• Overlap drainage mat six-inches at seams by pulling back filter fabric, applying ECOLINE-R, and snapping dimples together. On wall horizontal seams, top sheet should overlap bottom sheet.
