Usage

“Power-Protect O-95” is fit for hairline cracks, wide crack and joints, and for gushing leaks. These can be especially challenging because large quantities of water can wash out the resin before it sets. That is why we have developed a products and technique to tackle gushers. “Power-Protect O95” is explosively expansive to shut down gushing leaks in seconds. It can expand up to 20 times its original volume, and it forms a rigid foam. Try injecting these materials behind the structure for best results.

Consumption

Has to be estimated by the engineer or operator and depends on the size of the cracks and voids,which need injecting and on the expansion rate of the chosen resin.

Advantages

•More than 99% closed cell after foam
•Pumped as single component, direct use without to mix extra catalyst
•Used for injecting cracks widths from 0.2 - 10 mm.
•Compressive strength is above 6 MPa Water tight .
•20 times expansion rate .

Cleaning

•Resins must be cleaned up immediately before it sets.
•Packers must be removed within 24 - 48 hours and patched with appropriate epoxy mortar .
•Electrical grinder can be used to remove excess cured resin that flowed out the cracks.

Packaging

Power-Protect O95 is available in 10 KGS Special Iron Pails

Preparation

If water leakage is found in the water tank or retaining wall, conduct a visual survey to locate the apparent source of the leakage. If the concrete structure is plaster all plaster should be removed from the affected area to expose the concrete below. There after mark the crack through which the water leakage is observed .

Drilling

Use a high quality rotary hammer drill to make injection holes with a varied distance from 15-50 cm to each other, according to the width of crack.
The drilling angle should be approximately 45 degrees or less to concrete surface and intersecting the crack, at a distance of ½ the depth of the concrete element from the crack.
Clean all the holes from dust using air pump.

Fixing

Install injection packers into drilled holes ensuring that top of the sleeve is just below the surface of the concrete to secure sealing of the injector.

Applying

•Power-Protect O95 is to be applied using the Injection machine (Ex. Smart X).
•Make sure that the delivery line and all the fitting are connected tightly and in new condition at all time. Also ensure that no contamination has entered the delivery system.
•Start the Injection machine with low speed to start the pumping process and increase gradually.
•Once the desired working pressure is obtained set the switch of the machine so that this pressure will both be exceeded. In a regular injection the injection pressure will be well below the 400 bar mark.
•Continue until the crack is filled completely and resin can be seen emerging from the crack surface.
•Then start the process with the next packer until all the packers are done.
•Allow curing overnight and removing the packers and close the holes with special epoxy mortar that can be applied by trowel, spatula or knife.
•If the water is seen at adjacent place 7 days later, the procedure should be repeated until the whole structure is dried.
