| NOH2O FAQS |
|
What do Sovereign Hydroseal do?
Using its unique proprietary product NOH2O, Sovereign Hydroseal offers technical expertise, turnkey solutions, and custom-engineered applications for both large and small water ingress issues in subterranean environments.
What type of underground structures does Sovereign Hydroseal fix?
Mines, tunnels, shafts and civil construction projects like basements, carparks and metro train stations.
What is a polymer-based emulsion (PBE)?
A polymer-based emulsion is a stable dispersion of polymer particles in an aqueous medium. Essentially, it's a mixture where tiny polymer particles are suspended in water, creating a milky or cloudy liquid.
What is the difference between a PBE and a cement grout?
Polymer-based emulsion grouts use a water-activated polymer as the primary binder, providing superior flexibility, water resistance, and chemical resistance compared to cementitious grouts. Cementitious grouts are a blend of cement, water, and additives that offer strong, stable, but less flexible bonds more suitable for general construction and equipment anchoring.
How do you use NOH2O and what does it set like?
Being a liquid and pumped, NOH2O is injected at low pressure with positive displacement pumps as a low viscosity liquid and sets to a solid but flexible impermeable rubber-like plug in fissures, voids and pore space.
Is NOH2O more expensive that a cementitious grout?
Yes, on a simple per unit cost comparison, but the cost-benefit in using NOH2O comes in quick, immediate results resulting in reduced downtime and project interruptions.
Why should I use NOH2O?
Unlike cementitious grouts, NOH2O is flexible and withstands washout; it can better withstand movement and shifting, reducing cracking; NOH2O offers excellent resistance to moisture and corrosive environments; NOH2O is highly durable and can provide a long-lasting seal. NOH2O grout is designed to penetrate areas where other grouts cannot, making it effective in tight strata and challenging conditions (i.e. high flow and high pressure).
How long has NOH2O been in use?
Over 50 years, it was originally developed in South Africa in 1972.
How long does NOH2O grout last?
Proven in field more than 50 years and laboratory tested to be +125 years.
Do Sovereign Hydroseal work outside Australia?
Yes, Sovereign has completed over 400 projects worldwide in over 40 countries on 5 continents.
Is NOH2O toxic?
No, it is classified as non-hazardous, is environmentally benign, and is certified for contact with drinking water.
Does NOH2O have a lower carbon footprint than cement?
Yes, significantly lower.
Can I purchase NOH2O to use myself?
No, Sovereign Hydroseal do not allow third party use of NOH2O because each solution is site specific and engineered to solve a unique problem; one solution does not solve all problems. Grouting services are performed by Sovereign-trained personnel to ensure optimal results.
