About us – Hippo Shield

HIPPO SHIELD

HIPPOSHEILD Geo-membranes from Chemco are proven solutions for water resource management for a variety of industries and applications from agricultural irrigation and water conservation to oil and gas containment and mining.

Our Geo-membrane portfolio is comprised of Hippo product families:
Chemco offers a range of durable Geo-membrane products for lining and directing water flow in retention ponds, canals, catch basins, ditches, and other water holding areas as well as fresh and flow back FRAC water impoundment. Our HIPPOSHEILD coated woven fabric geo-membrane liners are made with exclusive high density polyethylene coatings for maximum toughness and abrasion resistance.

HIPPOSHEILD geo-membrane liners are available in 12 feet wide widths and can be factory fabricated and transported to the work site. Combining that with the light weight construction of HIPPOSHEILD helps reduce transportation costs and the amount of field seaming required, which can translate to big savings in installation costs and timing. Liners come inmedium or heavy weight fabrics with varying coating thicknesses and a black/black color.

HIPPOSHEILD geo-membrane woven coated fabric liners are design for easy installation and long life, featuring unique benefits that make the mosteffective and efficientchoice.

FOLLOWING ARE THE POINTS TO BUILD STRONG AND LONG LASTING HIPPOSHIELD POND!

LAND SELECTION

The soil should be flat and soft.
The land should be rectangular or square in shape.
The ground water level should be low enough, so that water does not rise from the ground during excavation even after heavy rains.
After proper selection of land, excavation should be started.

EXCAVATION

Use pokland machine for excavation.
Excavated soil should be used for slope of the field.
Remove any stones in the field and all elements that will damage the pond liner.
Angle of the slope Should be 120 deg or more.

HOW TO LAY HIPPO SHIELD POND LINER

Make a cushioning layer of about 1.5ft to 2ft height with soft soil on the base & slopes of the excavated pond. Spray water on it so that soil doses not lossen up.
Use pokland or roller to compact the soil. Remove all stone or sharp objects or tree roosts which can damage the pond liner.
Open the HIPPO Shield fabric properly and spread it out according to the size of the pond.
Use skilled operators while laying down hippo shield liner and see to it that the fabric is not damaged during the process.
Advanced hot gun technology machinery should be used after laying the pond liner for seaming.
Installation should be done by authorized company or approved channel partner personnel.
Check the sealing in one meter increments.
Upon completion of the activity, the entire farm should be checked by an authorized technical engineer of the company and then the service quality report should be signed.
During filling water the soil & pond liner both will get compressed & stretched, to avoid damage to the liner release slowly the excess fabric from the edges of the pond to relive the stress.
Anchoring of all excess fabric should be done on all the edges of the pond.

HOW TO PROTECT HIPPO SHIELD FABRIC

After the completion of farm laying activity, fencing should be done of iron or strong and more durable metal on all sides of the farm to take care of the animal and other elements. The height of the fence should be at least six feet.
The slope on the outside of the field should be paved with sand or gravel so that the soil of slope is not carried away in case of heavy rains.
Make strong steps to climb the slope on the outside of the field and use rought surface material patch on one of the slope on the inside so that animal or person can come out of the pond if they accidentally fall.
Care should be taken while filling the pond with water by controlling the flow rate of water.
Double or Triple layer fabric should be placed under the water filling pipe into the pond so that the pipe does not damage the fabric.

CARE WHILE FILLING THE WATER IN HIPPO SHIELD POND

Fill the pond step by step while filling with water.
The pipe for filling the pond should be placed up to the back of the embankment.
The tip of the pipe should not extend too far into the pond.
Tie tubes / bags / sacks to the mouth of the pipe so that the water falling into the pond does not fall on the slope with strong force.
Care should be taken that the soft soil on the embankment does not slide down.
