WHAT IS ENGINEERED SOIL?
Engineered soil is manufactured soil consisting of sand, silt, clay and organic amendments. We design custom-blended soil mixes to meet project requirements with characteristics tailored to your specific purpose.
ROOFTOP GARDENS
Green roofs are part of the healthy city movement, absorbing noise pollution and creating a peaceful meditative environment with an aesthetic appeal on building rooftops. Plus, they’re helping to increase property values.
RAIN GARDENS
Our engineered mix of washed sand (70-90%) and sphagnum peat (10-30%) efficiently collects water from surfaces, filtering out pollutants and storing water short-term. This blend ensures clean water infiltrates the soil gradually, supporting garden health and recharging groundwater.
CU-STRUCTURAL SOIL
That’s what makes Plaisted Companies the Midwest’s premier supplier of engineered soils. We custom blend soils using our computerized Accublender™, controlling the quality from processing and screen through to delivery. Our Soil Specialists will help you select the perfect mix for your application.
IRON-ENHANCED
SAND & MIXES
Plaisted offers a cutting-edge solution for stormwater management. Developed from University of Minnesota research, our product combines sand with 5% iron filings to effectively capture up to 88% of phosphates in runoff. This innovative filtration method significantly outperforms traditional sand filters, providing a cost-effective and efficient way to reduce phosphorus pollution in our waterways.
MN DOT SOIL MIXES
Our four-bin Accublender™ is used to create these mixes. It features a computerized blender with an on-board screen deck that removes oversized particles and a mechanical paddle wheel that ensures uniformity. It automatically adjusts for flow rates of material and stops the conveyor belt when feed bins need to be replenished.
