Soil Stabilization
Construction projects are only as strong as the foundation they are built on. For 25 years W&D Navis has been stabilizing central & southern Wisconsin's soils through its Soil Stabilization services.

What is Soil Stabilization?
Soil stabilization improves the stability of weak soils by utilizing chemical, mechanical, or combined practices to achieve engineered goals. These methods are proven to have a cost savings over traditional undercutting and importing of materials. Typical use products for soil stabilization include, but are not limited to Quicklime, Lime Kiln Dust, Cement & Geotextiles.
Our Process
1. Analyze Soils
Analyze soil chemistry for accurate product selection
2. Spread
Apply appropriate stabilization material: quicklime, lime klin dust, cement
3. Incorporate
Utilize a reclaimer to incorporate stabilization product into native soils
4. Compact
Roll reclaimed soil with soil compactors
5. Grade
Grade reclaimed site materials to spec for final density testing

Soil Stabilization Products
Quicklime
Also referred to as lime (Calcium Oxide, CaO). Quicklime is derived from high quality Limestone deposits through a process called calcination. Calcination is achieved by crushing the limestone to a desired size, heating that material in a kiln to temperatures up to 2000 degrees F causing the loss of carbon dioxide (CO2) and leaving behind Quicklime. Lime is used to good advantage in reducing the plasticity index of the soil while providing the fastest drying option.
Lime Kiln Dust, LKD
Also referred to as Calciment, LKD is a co-product of the Quicklime manufacturing process. As a result of calcining high quality crushed Limestone, the heating causes a chemical release of carbon dioxide (CO2) which ultimately leaves behind two products, Quicklime and LKD. Lime Kiln Dust is a fine powder containing a combination of calcium oxide (CaO), magnesium oxide (MgO) and pozzolans. This product effectively reduces plasticity and can stabilize a wide range of problematic soils.
Geotextiles
Geotextiles make use of mechanical soil stabilization compared to chemical processes. Geotextiles are puncture resistant fabrics that interlock the subgrade soils, providing increased strength and bearing capacity in places where chemical processes are not considered beneficial.
Cement
Cement stabilized soils are an engineered mixture of pulverized in-situ soil, water and Portland cement. The result is a subgrade with bound materials and increased strength. Coarse grained soils are ideal for cement stabilization.
