Sprayroq® created its first polyurethane in 1990 in Jacksonville, Florida. Since that time, Spraywall® has been applied to well over 1,000,000 structures throughout North America, Europe and Asia.
Absolutely! Due to urban sprawl and the rebirth of “grayfields”, more and more communities and engineers are taking the extra step of coating new wastewater and water structures to extend the life of the service to the community. As infiltration and the effect of corrosive gases are two primary cause of deterioration in a collection system, the addition of a corrosion barrier to a new structure will ensure a longer life to the system and a better ROI for the taxpayer.
You must stop any infiltration using appropriate water-stopping material before applying Spraywall. Once that has been accomplished, finish preparing the structure for spraying. Once you spray the substrate with Sprayroq’s SprayWall structural product, the polyurethane will bond to the concrete, steel or masonry, sealing of the infiltration.
Yes, you could, but it probably isn’t practical or cost effective. SprayWall and SprayShield were formulated to work in a water and wastewater environment. The use of the product for other sealing and corrosion coatings may not be the best answer. Check with your local SCP or Sprayroq to see if your application may be right for this product line.
No, Sprayroq products have a tenacious bonding ability to not only concrete, but steel, aluminum, masonry materials and other substrates that may be used in our water and wastewater systems. SprayWall and SprayShield will not bond to polyethylene.
Some of the applications for Sprayroq products include coatings or linings of the following structures:
• Manholes (Water and utility)
• Junction boxes
• Lift stations
• Storm sewers
• Wet wells
• Grit chambers
• Retention ponds
• Secondary containment fields
• Water tanks
• Corrugated pipes
Plus many other applications in the water industry and other industrial infrastructure rehabilitation and corrosion coating applications.
Yes, all batches are tested to product specifications such as viscosity and reaction and cure rates. Testing occurs at both the production plant and lab which are co-located with our home office in Irondale, Alabama. Any discrepancies would initiate an investigation of that particular batch.
If the 55 gallon drums remain sealed, the expected shelf life of the products is one year. If the drum has been opened and may not be used for a time, be sure to reseal the drum tightly to protect the product from moisture and top off the void in the drum with nitrogen if possible.
Yes, we have copies of all of our third party test results available on this website – they are available on each product’s detailed information page located under the products tab above!
The warranty for the Sprayroq product line is three years from the date of application. Sprayroq warrants that its material is free of defects at the time of application. Should any product be found to be defective, the product will be replaced by Sprayroq or the money will be refunded to the SCP.
Yes, in fact, if you visit our website, you will find a sample specification for corrosion coatings and structural rehabilitation under our Specifications section of the website.
Sprayroq has included on this site a number of projects that have been completed and documented by our SCP base. These case studies present an overview of the project, some photos and the contact information of the SCP who completed the project. This is for those who have similar projects to contact the contractor who successfully completed a similar project.
Dynamic Mechanical Testing is a procedure for predicting the life of the physical properties of a material.
A procedure for measuring the adhesion to a substrate.
