The present invention provides improved methods and compositions for grouting heat exchange pipe in a hole or trench in the ground. The grouting compositions of the invention have quick set and high thermal conductivity properties and are basically comprised of an amorphous silica material, an alkaline earth metal oxide or hydroxide, a water swellable clay and water present in an amount sufficient to form a slurry. The compositions optionally also include a set retarder and a thermal conductivity increasing agent.
