COLMAGEL*
CLOGGING POLYMER FOR ARTIFICIAL LAKES AND PONDS

COLMAGELwas created in 1990 by PROMAFOR, after a meeting with M. Bernard Rivoire, adviser of Agriculture Chamber of Saint Etienne. M. Rivoire made some tests since a time to find a product able to stop water losses from lakes and ponds.

These lakes, when they are built by a confirmed company are expensive. They have often some important losses of water. They are dry in summer, when farmers need water for their fields.

That's why PROMAFOR has proposed a process to stop the losses, avoiding rebuilt the lake for a cheaper price.

USE

COLMAGEL is a mix of granular and powder polymers :

- The granular polymer swells more than 200 times its volume in presence of water. The water is used as a clogging agent. The polymer make a structure with a foam rubber aspect.
We obtain a spectacular result : the water "grain" can reach a size of 2 to 3 centimers, able rebound if you through it on the ground.

- A second sticking viscous blend of polymers make with the grains of water plates of several square meters and about ten liters.
All Together are sucked in by the cracks and by the porosity. When they are inside, they continue to swell, the escape of water is stopped.

RESULTS

The results are near 80% of success. No other method can offer a similar result in a so short time (a few hours) and with a so cheap cost (nearly 250$ for 350 m˛).

DESCRIPTION

COLMAGEL is commercialised in grains size 0.75 to 3 mm, in 25 and 5 kg bags (for 350 and 75 m˛ treatment respectively).
Note that it's rare that all the lake area is treated. Only the areas having the most important risks of losses receive the COLMAGEL, the dyke by example.

APPLICATION

The product is spread on the lake with hands or with a powdering machine. The concentration is near 75 g/m˛.
You have to use the product when the weather is quite : no wind, no rain , no waves and with a water temperature up than +5°C.
