External Waterproofing & Gas Membrane Newton HydroBond SAGM - Self Adhesive Membrane
Verified by manufacturer 4 months ago
DoP
Certificate type
A flexible and durable membrane designed for external waterproofing and gas-proofing of below-ground structures, post-applied to below-ground concrete, block or ICF walls.
Application
The product is typically:
- Post-applied sheet waterproofing to retaining walls of below-ground structures.
- Used in conjunction with Newton HydroBond pre-applied membranes to provide continuous Type A waterproofing around the whole structure.
Description
A high-performance, self-adhesive membrane for the external waterproofing and gas-proofing of habitable below-ground structures. A composite of polythene and aluminium, coated on one side with a bitumen polymer adhesive, the membrane is post-applied to concrete, after removal of form-work, or to built walls such as block or ICF.
The membrane is flexible and durable and exhibits high resistance to impact, tear, puncture and settlement.
This combination of high strength and high flexibility results in excellent crack-bridging capability at places where cracks will occur within the concrete. The bitumen polymer adhesive provides a very high bond to the substrate at temperatures as low as 5°C with exceptional peel adhesion qualities, and so prevents migration of water between correctly prepared substrate and the membrane.
Features and benefits:
- Type A (barrier) waterproofing membrane.
- Resistant to aggressive ground water chemicals.
- Effective barrier to all ground gasses.
- Dimensionally stable and flexible for easy detailing.
- Quick and simple to install - no jointing tapes.
- Required ancillaries: Newton HydroBond SA LT Primer and Newton HydroBond SAGM Detail Strip.
