DifGel Acrylic Resin

DifGel Acrylic Resins allow for waterproofing injections while water is present and under high pressures. With its stability and ability to gel at any setting time, DifGel is perfect for almost every active leak.


• DifGel Resin does not pollute the water table and is environmentally friendly
• DifGel Resin is non-toxic to the operator and environment
• DifGel Resin is injected through dual lines of a variable pressure pump, easily controlling the quantities used.
• DifGel Resin has a low flow resistance due to its low viscosity. This enables operators to not only seal cracks but to also seal the smallest capillaries.
• DifGel Resin contains a short-lived color dye enabling the operator to visually control the injections. A few minutes after the injection (and full polymerization) the dye completely disappears leaving no visible stain.
• DifGel Resin is chemically a non water-reactive product. Its' polymerization does not involve water, producing better control of the setting time.
• After injection, DifGel Resin becomes a gel, in a time which can be adjusted, chemically, from a few seconds to a few hours.
• DifGel Resin setting time is not affected by polluted or salted water.
• DifGel Gel is water and gas proof.
• DifGel Gel will remain water tight even if water disappears and reappears over time.
• DifGel Gel will resist even permanent water pressure:
When in contact with water, DifGel Gel will swell, due to its hydrophilic properties. These properties are incorporated into three(3) dimensional polymer frameworks, ensuring that even if the cross section of the joint or cracks change, the gel remains intact. Water does not induce chemical deterioration but on the contrary acts as a partner, further maintaining the gel in a condition of maximum expansion.
• DifGel Resin is stable with alkalines to 12ph, therefore not attacked by wet concrete.
• DifGel is insensitive to diluted acids, bases, and salts.
• DifGel gel is insoluble in water, solvents and hydrocarbons.
• DifGel gel is inert and unable to damage bitumen, membranes, joint-ribbons, construction materials and concrete.
• DifGel Resin is non-biodegradable and therefore cannot be a growth aid for fungi, microorganisms, mold or bacteria.
• DifGel gel is very adherent and highly elastic.
• DifGel Resin can withstand concrete works and/or ground deformations.
• DifGel gel can withstand freezing temperatures.
• DifGel gel has no effects on any materials in which it may come in contact.

Chemical Tests

DifGel Acrylic Resin was completely polymerized with a setting time of one (1) minute. The test sample was kept at room temperature for a period of 42 days. The degree of discoloring, consistence, and dissolution were determined. The test sample was characterized as either "stable" or "unstable".
