Garibaldi Pumice Ltd. provides dacite pumice for use as lightweight backfill material. Our white pumice is approximately ¼ the weight of sand and gravel.
Geotech Aggregate has been extensively used in construction projects challenged by compressible soils, infrastructure susceptible to damage by excessive fill surcharge, and in areas requiring reliable drainage. Our dacite pumice can also be used as a positive drainage medium on sites with compact soils that have limited natural infiltration.
Dacite pumice has been employed in a variety of construction applications including roadbeds, bridge abutments, retaining walls, pipeline protection and drain fields.
