Crack injection resin for stopping water flow

Uses:

For injecting into cracks in concrete to temporarily stop the flow of moving water. When used in conjunction with Nitofill UR63*† provides an effective system for crack sealing in wet conditions.

Advantages:

- Reacts with water to produce water resistant foam to stop water
- Rapid acting, to produce water stop against moving water under pressure
- Re-injectable with Nitofill UR63 to form permanent seal

Description:

Nitofill WS60 two part liquid polyurethane is mixed in the proportions supplied and injected into cracks in concrete. It reacts with moving water to form a foam barrier. Used in conjunction with Nitofill UR63 it forms a permanent seal in cracked concrete.

Specification clause:

Water-stopping crack injection resin
The foam water-stopping crack injection resin shall be Nitofill WS60, a two part foaming liquid polyurethane. When mixed in the proportions supplied and injected into cracks in concrete, the resin shall react with moving water to form a foam water-stopping barrier.

The water-stopping injection resin shall have the following properties; pot life, in the absence of water, 6 - 8 hours at 20oC, 3 - 4 hours at 35oC; reaction time with water, 5 - 30 seconds, dependent on temperature; viscosity of 2 - 3 poise, at 20oC; specific gravity of 1.14 ± 0.06; foam density of 0.025.
When used in conjunction with Nitofill UR63, a flexible two part polyurethane injection resin, it shall form a permanent seal in cracked concrete.
