Porous Fill – Ordovician Dolomitic Limestone
POROUS FILL is also known as pipe bedding, clean rock, porous backfill, porous fill, chips, bedding stone, drain rock, underlayment, base material, pothole repair stone, and clean chips. Pattison produces POROUS FILL products in our state-of-the-art, jaw/cone crushing plant. Our crushing plant is built around a sophisticated compression crushing technology that reduces fines generation and increase fractured faces.
Where is Porous Fill Used
Pattison POROUS FILL is used as an underlayment, pipe bedding, and road base. It is used in drainage fields, walkways, construction projects, and landscaping. POROUS FILL is loaded for shipping with our direct to rail transfer system. As a result, products move quickly from production to rail with minimal handling, dramatically reducing product degradation and loading costs.
Porous Fill Production
This material is commonly ordered in specific sizes and physical properties. Because of this, we harvest material from a variety of Ordovician Dolomitic Limestone ledges within our quarry to meet specific requirements. Pattison’s stone products are sourced from a variety of very high quality ledges, each with specific properties. Limestone extracted from these ledges contains minimal deleterious material, and performs exceedingly well on multiple quality assurance tests.
Pattison POROUS FILL meets the quality usage designations in the states of Iowa, Missouri and Minnesota. Here’s what Wikipedia has to say.
