4. Polymer vs. soil condition23

Charge Orientation in Soil

• Negative charges are in majority at the flat surfaces of a particlea particle

• Positive charges in lower t ticoncentration are more

common at the edges or irregular surfaces


Interaction of PolyMud® to Soil

Due to the high concentration of negative charges within the soil particles the binding of the soil to the the

l t i ipolymer matrix is conveniently achieved through the positive chargescharges.

Water molecules release is avoided. Thisaffinity allows for the soil to be filled withseveral polymer filaments preventing itsf ifragmentation.

G3® SystemPOLYMER VS GROUND WATER

There are no specific requirements on ground water. Numerous types of groundwater are faced throughout excavations.

POLYMER VS GROUND WATER

No free water available

G3 System is tolerant to water intrusionsy

Water with Acid pH have to adjusted at ph >6

Polymer absorbs water and keeps it

Bentonite has free water and cake is permeable whichallows for aggressive water to disrupt bentonite

Removal and disposalREMOVAL

G3 polymers need not to be to removed from site

REMOVAL

After a simple and fast treatment G3 polymers can be disposed on site

Disposal procedure (30min):

1. Correct pH to 6 – 9 with hydrochloric acid (HCl)

DISPOSAL

1. Correct pH to 6 9 with hydrochloric acid (HCl)

2. Break the polymer chain with Calcium Hypochlorite

After the treatment the polymer is ready to be disposed on thei t ith t i k ( it i il)environment without any risk (city sewage, rivers, on soil)
