Non-hydraulic grouting composition of a water resistant polymer emulsion and a mixture of a coarse and a fine filler

A non-hydraulic grouting composition which consists essentially of

• a water-resistant polymer emulsion having a solids content of at least 40% by weight of the emulsion wherein the polymer is a polymer of an ethylenically unsaturated monomer;
• 10% to 35% by weight of the total composition of a fine filler having an average particle size less than 140 mesh;
• at least 50% by weight of the total composition of a coarse filler characterized by an average particle size wherein not more than 10% passes a 140 sieve and none is retained on a number 6 sieve and an American Foundry Society grain Fineness Number less than 100 but greater than 10;
• wherein the total composition has a viscosity of 50,000 to 2,000,000 cps, a total fine and coarse filler content of from about 70% to 90% by weight, and a total aqueous volatile component content of from 5% to 15% by weight.
