Fosroc Nitofill Pu150 20kg

Nitofill PU150 is a single-component, hydrophilic polyurethane injection resin designed to seal leaking cracks, joints, and voids in concrete structures. Upon contact with water, it rapidly reacts and expands—up to 25 times its original volume—forming a flexible, durable, and watertight elastomeric seal. Ideal for waterproofing applications in below-ground or water-retaining structures, Nitofill PU150 is solvent-free, non-toxic, and highly resistant to environmental conditions.

Key Features:

• Reacts with water to form a flexible, expanding foam

• Expands up to 25x its original volume to effectively fill cracks and voids

• Excellent adhesion to concrete, brick, mortar, and other mineral substrates

• Solvent-free and TDI-free – safe for use in sensitive environments

• Resistant to mild acids, alkalis, and most organic solvents

• Forms a resilient seal that accommodates structural movement

• Can be injected directly or in combination with water

• Complies with AS/NZS 4020:2005 – suitable for use in contact with potable water

Typical Uses:

• Sealing leaking cracks, joints, and voids in concrete

• Waterproofing basements, tunnels, retaining walls, and water tanks

• Infrastructure exposed to intermittent or continuous water ingress

• General-purpose injection resin for inaccessible or hard-to-reach areas

Packaging:
20kg drum

Application Method:
Injected as a single component or with water using standard injection pumps. Use with Nitofill Accelerator where faster reaction time is required.
