  1. High-Performance Joint Sealing: Designed for construction, movement, and expansion joints, HydroCoat Monoflex accommodates irregular and frequent movement while maintaining a waterproof seal over the joint.
  2. Versatile Adhesive System: Consists of flexible polyolefine (FPO) tape and solvent-free epoxy adhesive, providing a reliable bonding agent for sealing construction joints, movement joints, and cracks in below-ground and water-retaining structures.
  3. Easy Application, Excellent Bonding: HydroCoat Monoflex Adhesive is easy to mix and apply on-site, requiring no primer, and exhibits excellent bonding characteristics with a wide range of building materials, even under damp conditions, making it an integral part of the Newton HydroCoat System for internal Type A waterproofing solutions.

A high performance joint sealing system for construction, movement and expansion joints. Newton HydroCoat Monoflex is particularly suitable in critical areas where irregular, high and/or frequent movement might be expected, as it is able to accommodate the movement whilst maintaining the waterproof seal over the joint.

The system consists of the HydroCoat Monoflex waterproofing tape, manufactured from a flexible polyolefine (FPO) which is installed to the substrate with the suitable Newton HydroCoat Monoflex Adhesive.

Newton HydroCoat Monoflex Adhesive is a two-component, versatile and solvent-free epoxy adhesive which is used as the bonding agent for sealing construction joints, movement joints and cracks in below-ground and water-retaining structures with the HydroCoat Monoflex joint sealing system.

HydroCoat Monoflex Adhesive is easy to mix and apply on site, requires no primer, and exhibits excellent bonding characteristics with a wide range of common building materials, even under damp conditions.

The HydroCoat Monoflex system is an ancillary within the Newton HydroCoat System, an internal Type A waterproofing solution for projects that require an internally applied system to resist water ingress.
