The Solution: EcSS 3000™
EcSS 3000 is a water soluble product which when applied to clays with a swell/shrink potential will alter the physio-chemical properties of the clay, thus reducing the swell/shrink potential of the clay. The very diluted chemical solution is prepared by mixing (1) part chemical to (300) parts water and can be applied by either injecting into the soil or application using a water pull.
For new construction of roads or building pads, EcSS 3000 can be applied using a water pull as shown below:
Another method for placing EcSS3000 in new construction is by injection as shown below:
For the remediation of distressed structures or distressed roads resulting from expansive clays, EcSS 3000 can also be applied using a hand injection system as illustrated below:
This injection method uses a ½ inch steel wand (probe) to inject the very diluted chemical 5 to 7 feet deep into the soils beneath either the distressed structure or distressed road. The wand penetrates the soil using hydro-jetting or drilling methods. The chemical is injected as the wand penetrates the soil and then is withdrawn in 1 foot intervals as the injection is continued.
Most clay swells below foundations produce edge lift (lifting of the outside of the foundation relative to the center of the foundation). To address edge lift swell conditions, two Options are shown for remediating this condition. The drawings in Options 1 and 2 illustrate and explain the method used for remediating edge lift swelling clay conditions beneath existing structures using the hand held injection wands. Option 1 illustrates the remediation of the swell conditions using just the chemical injections beneath the exterior foundation of a structure. Option 1 is presented as follows:
Option 2 illustrates the remediation of the swelling clay conditions beneath an exterior foundation using both the chemical injection and a PVC liner apron placed 4 to 6 inches below the ground surface. Option 2 is presented as follows:
The chemical injection should satisfactorily reduce the swell potential of the clay soil; however, the PVC liner apron provides additional assurance by helping to maintain a constant moist condition in the clay soils beneath the foundation. This method also allows for the removal of surface water using the perforated drain pipes placed in a swale above the PVC liner.
In some instances remediations will require injections beneath the entire floor slab of the structure. This type of injection beneath the floor slab is required when there is a Center lift clay swell condition. Center lift conditions occur when there is more swell occurring beneath the center of the floor slab versus the edge of the floor slab.
Since having been successfully used on roads, highways, and airports since the mid 60’s, this technology has increasingly proven to be economical and ideal for use by builders and homeowners for structures in areas with expansive clay soils.
Advantages:
• A fast, cost effective and permanent solution
• Reduces maintenance costs
• Not harmful to landscaping, ground water supplies or wildlife
• Environmentally friendly – 100% organic
• Excellent sales feature for homes built on swelling clay sites or homes that have previously experienced swelling clay distress
