"The Engineered Solution to Sticks & Stones"
The Rock is a multi-faceted dimensional object designed to provide incremental annular spacing easily and accurately. By simply turning it to the desired orientation, The Rock will ensure adequate space for the placement of mortar around the entire opening to create a watertight and soil-tight connection.
The Rock’s incremental design helps to set pipe elevation and ensure proper system flow, and its flow-through design allows it to become an integral part of the mortar or concrete used to seal the opening.
