Polyurea Liners for Tanking and Secondary Containment

This is a  video showing the refurbishment of a drinking water tank in Italy with our pure Polyurea Rayston(blue colour) sprayed onto our Geomax Spray 200 geotextile. This system has saved a lot of money and time in substrate preparation and priming.

Firstly the GEOMAX SPRAY 200 is fixed over the concrete surface. If the concrete surface is not well dry or not well repaired, it is not a problem. Afterwards a seamless continuous liner is created by spraying polyurea over the geotextile.

GEOMAX SPRAY 200 is a special geotextile, needle felt. Needle felt geotextiles have got some advantages over thermobonded geotextiles: better elongation, flexibility and puncture resistance. However on the other side the quantity of resin needed to well coat a geotextile like this is quite larger and there is the risk to have got some lose uncoated fibres, so most of the times the finish coat has got low quality and no nice aesthetical appearance.

GEOMAX SPRAY 200 is thermobonded in just one side, the side where Polyurea should be applied, that allows for lower resin consumption and an excellent finish by keeping the better mechanical properties of a needle felt geotextile.

Waterproofing of a closed concrete drinking water tank



This is the system for the waterproofing of a closed concrete drinking water tank with a seamless thick elastomeric membrane, liquid applied (cold), able to bridge over fissures and also to resist continuous contact with water. The sistem is valid for a new concrete tank, in order to prevent the occurrence of leaks in the future and also for the refurbishment for an old tank with already some leaks that should be repaired.


Boths systems are liquid applied and once they get cured form a seamless and
continuous coating. IMPERMAX AQUA 2K coating is flexible and elastic with  an outstanding ability to bridge over fissures. However a cementitious-acrylic
coating is just a very slight flexible, but not elastic, it has a the capacity to adapt itself to a small movements of the concrete surface, however it has not the capacity to bridge over medium or large fissures. The result is that normally some leaks appear relatively shortly after the application of an acryliccementitious coating, mainly if it is a new tank that is still setting on the ground.


Epoxy 100 Primer is a two component epoxy resin, that even it has no solvents
it has got very low viscosity. It should be applied over a well dry surface.
Humidity primer is a two component epoxy resin, water based that could be
applied over a surface with small remain of moisture. When it is applied it has
got a milky appearance, once it gets dry, it becomes clear. The curing time
could be accelerated (low temperatures, closed area) with the Accelerator IH.
IMPERMAX AQUA 2K is a two component polyurethane resin, totally free of
solvents, roller applied. It has got quite low thixotropy, so over a vertical surface should be additivated with the Thickening Additive (powder form). It has got a drinking water certificate, following European specifications.


The Impermax Aqua 2K, the Humidity Primer and the Epoxy 100 Primer could
be applied with a roller. The surface must be smooth, dry, free from oils, greases, waxes, silicones…If it is new concrete, it should be well-cured and dry and free from laitance.

0- Repair the cracks, holes, remove part of the surface that is not well adhered..

1- Primer
1.1: If it is new concrete water tank, well-cured and well dry: 1 coat of about 0,3
kg/m2 of Epoxy 100 Primer. 2 component Epoxy resin, 100% solids.

1.2: If it is a water tank filled with water in the past, with remains of moisture
inside the surface: 1 coat of about 0,3 kg/m2 of Humidity Primer, two
component Epoxy resin, water-based. In order to help the resin get cured in a
closed area (and help the water evaporate from the resin) forced ventilation is
advisable. In a closed area Accelerant IH is also advisable.

2- Reinforcement of singular points: cracks, joints, corners…Apply a first thin
coat of Impermax Aqua 2K and reinforce it with the non woven geotextile
GEOMAX. The self adhesive strip Butyl Tex could also be used.

3- Apply one coating of approximate. 1,5 kg/m2 of IMPERMAX AQUA 2K with a roller (2 component elastic PU resin, 100% solids with no solvents). Over the
vertical surface the Thickening Additive must be used to avoid the sagging of
the resin (1-3% of additive in the resin). The vertical surface is coated firstly and afterwards the horizontal surface.


Let the material dry about 10 days before filling the tank with water. Rinse the water tank with water and mild detergent before fill it with drinking water.

Stops Cracks Before They Start

Unlike traditional steel methods, Fibermesh fibers are uniformly distributed throughout the concrete mix and are always positioned positively so as to become an integral part of the concrete composite.

Fiber mesh synthetic concrete fibers reduce the formation of plastic shrinkage and settlement cracks by discouraging the segregation of the concrete ingredients while adding tensile strain capacity to plastic concrete. This reduction or elimination of plastic cracks enables the concrete to develop its optimum long-term integrity.

The Fibermesh “network of reinforcement” reaches every cubic inch of the concrete section for uniform reinforcement that minimizes early age cracking, reduces water migration, increases impact, abrasion and shatter resistance and provides residual strength and crack protection throughout.

Available with patented e3® technology that is engineered in specific lengths, thicknesses and mix ratios to enhance uniform distribution in fresh concrete.

Media Hycrete Introduces Performance Warranty Against Flooring Failures

New Hycrete System V Solves Moisture-Related Flooring Failures

CARLSTADT, N.J., May 12, 2010 – Moisture in concrete has emerged as a leading cause of flooring failures – and litigation – in construction. EPA bans have eliminated VOCs (volatile organic compounds) from flooring adhesives, but leave adhesives more vulnerable to water.

Advances in vapor barriers have helped, but so many things can go wrong in construction that no manufacturer has yet been willing to offer a performance warranty.

Hycrete, a firm dedicated to solving problems associated with water in concrete, today introduced a full performance warranty against moisture vapor related flooring failures. Hycrete System V combines hydrophobic concrete admixtures and field service to protect flooring and building interiors from moisture vapor-related problems. Specifiers, contractors, owners, and the market as a whole now have access to an elevated level of insurance and peace of mind. Using Hycrete System V reduces the potential for costly shut down times, interior damage, and revenue loss. Flooring manufacturers typically require a specified MVER (moisture vapor emission rate) before flooring can be installed. Concrete that hasn’t adequately dried, that has absorbed moisture from the ground, or that has been rewet by rain, make these requirements difficult to meet; sometimes they are simply ignored.

Hycrete System V eliminates this headache. Flooring can now be installed after 28 days of concrete placement with no fear of failure, accelerating construction schedules. Also, concrete that has not yet received flooring may be re-wet due to rain or site conditions, re-setting the drying clock and delaying flooring installation. Hycrete W1000 admixture (a component of Hycrete System V) keeps water out of concrete by shutting down capillary absorption; the drying clock is not re-set and flooring can be installed as scheduled.

“Hycrete’s introduction of a performance warranty to the flooring market not only rounds out the Hycrete product line and leverages its existing high-caliber field service team, but reduces the risk of moisture-related flooring damage for specifiers and builders in critical markets such as healthcare and education, two of the most robust markets,” says Hycrete CEO, Richard Guinn.

Hycrete System V is ideal for below- or on-grade slabs where flooring is being installed, as well as for suspended slabs where there is concern of concrete re-wetting after placement. Specific applications include hospitals, schools, office buildings, and multi-family structures. Hycrete System V deepens the Hycrete product line and provides another solution for specifiers and builders when addressing moisture-related building concerns.

President Obama Recognizes Hycrete, Inc.

Hycrete CEO Joins CleanTech Leaders for White House Roundtable on How Clean Technology Can Stimulate Economy.

CARLSTADT, N.J., July 2, 2009 – Hycrete, Inc. CEO David Rosenberg was among eight CEO’s of clean technology focused companies invited to participate in a roundtable hosted by President Barack Obama regarding the economic impact of environmentally friendly technologies. The panel also included members of the President’s staff, including Energy Secretary Steven Chu, EPA Administrator Lisa Jackson, and Chief Technology Officer Annesh Chopra.

The industry leaders opened the discussion with examples of how their firms are contributing to innovation and economic growth in hard economic times. In turn, they offered thoughts on steps the Federal Government can take to help accelerate adoption of new technologies, creation of technology jobs, and establish U.S. leadership in CleanTech. Rosenberg walked the President and his staff through Hycrete’s innovative leadership in building materials and construction.

In his remarks following the White House meeting, Obama called the participating firms “some of the most innovative energy companies in America,” and said their industries represent a “a big piece of America’s economic future.”

“It’s men and women like these who will help lead us out of this recession and into a better future. My job – and our job as a government – is to do whatever we can to unleash the great generative powers of the American economy by encouraging their efforts. And when you hear the innovation that’s taking place … [including] new concrete materials that last longer and are waterproofed from the inside out, and that can mean that bridges and roads and buildings can last 20 or 30 years longer than using conventional concrete … that gets you excited.

Hycrete CEO Rosenberg announced, “I’m thrilled to see the success of our business and our innovations recognized at the highest levels of government and in such a high-profile group of corporate peers. We are proud of our efforts to bring value to the economy – and to help increase federal stimulus impact by reducing building and maintenance costs and accelerating construction schedules for public projects.” Rose Garden press briefing (David Rosenberg stands on the top row on the right in the red tie)
