Asmaco Gold Universal Multi Foam is based on MDI (Methylene Diphenyl iso cyanate) polyurethane pre- polymer & accelerator. The system only reacts when it comes in contact with water, producing a relatively stiff & inert polyurethane foam (PU). It is a 100% solid & solvent free polyurethane grout for quick temperrory closing & sealing of water bearing cracks, cavities and leaks under hydrostatic pressure. The systems foams to 30-40 times its volume in the presence of water & can be an effective means of arresting running water leakage.

Areas of Application:

Defective concrete – (crack & honeycomb).

Deep basements, rafts, lift pits

Construction joints

Drinking water tanks & reservoirs

Waste water/ Effluent tanks

Sewers, manholes, utility boxes, etc

Dams & canals

Tunnels

Brick / stone masonry

Pipe intrusions

Soil stabilization    

Features and Benefits:

Very low viscosity benefits penetration into hairline cracks.

100% solid & solvent free composition helps in shrinkage free grout

On reaction with water foams around 30 times which benefits filling of wider cracks & honey combing      of concrete structures.

Bonds strongly to dry & wet concrete, bricks & stones.

It is safe & suitable for drinking water contact.

It is CFC & solvent free hence non-toxic.

Both negative and positive.
