HPI Everdure Caltite system provides total, effective, integral waterproofing

This interaction features how Nutech’s HPI protects concrete structures against water ingress and dampness.

How do your construction chemicals specifically address the challenges of rainwater or groundwater entering concrete structures?
The hydrophobic pore-blocking ingredient (HPI) we developed offers heavy-duty integral waterproofing. The admixture contains a damp-proof and corrosion-proof hydrophobic matrix that prevents absorption and lateral transmission of water or dampness and provides a dry and damp-free structure. Using this product eliminates the use of plastic or waterproof sheets, membranes, and external coatings. The product is thus high-performing, cost-effective, and saves substantial construction time.

How do Nutech waterproofing chemicals mitigate water ingress and moisture-related damage during heavy rainfall?
Normal concrete or high-quality concrete inevitably contains capillaries and microcracks. Some reasons for the porous nature of concrete structures include the dehydration of excess water during curing, the presence of air-entering agents, shrinkage, etc. These shortfalls are inevitable in concrete structures. These factors allow the passage of water by natural capillary absorption, resulting in dampness, leakage, and corrosion of the reinforced concrete. Our HPI admixture reacts with the calcium of the cement to form a barrier-changing surface tension, resulting in a concrete which is inherently water-repellent and non-absorptive. The polymer molecules fill up the capillaries formed by bleed water. The molecules bind together to form a physical plug, thus acting as a waterproofing barrier preventing the water from entering the structure.

How have your products contributed to concrete structures’ long life and durability when exposed to water ingress?
Our HPI Everdure Caltite system provides total, effective, integral waterproofing and corrosion resistance to concrete. Our company has over 30 years of proven track record in providing maintenance-free structures without the need for periodic repairs, replacements, or other surface-coating treatments. Our products are high-performing and provide major savings in both time and cost.

What are your latest advancements in concrete technology aimed at improving efficiency and productivity in construction projects?
Cementaid International specialises in manufacturing HPI admixtures and surface treatments to extend the structural life of concrete using a unique waterproofing technology. Inception in 1953, our company has serviced and supported many major industries owned by public and private projects. The forte of our company is to provide well-proven waterproofing systems for the construction/marine Industry. The basic principle of our HPI is to incorporate itself as the waterproofing agent and form an integral part of concrete, ensuring that the structures remain dry almost throughout the service life. There is no need for additional external waterproofing, such as membrane or coating.

What are the typical applications of HPI?
HPI may be used in basements, habitable substructures, swimming pools, suspended swimming pools, lift wells, car parks, tunnels, and other substructures prone to contamination, wet ground conditions, or hydrostatic pressure. The product may also be used in industrial/chemical/food processing units, trafficable or landscaped concrete roofs, podium decks, and locations where groundwater and reclaimed land or service environments may contain organic acid, sulphates, chlorides, and other harmful salts. Our HPI also finds application in jetties, wharves, boat ramps, and all concrete in marine environments where long-term maintenance-free service life is desired.
