When perfect working conditions are a pipe dream, consider GeoSpray®

Posted by: Joe Royer

Perfect working conditions in the storm and sanitary field are few and far between. When they do exist, take advantage —unforeseen interruptions can wreak havoc on your schedule and budget. However, that’s not to say there aren’t ways of mitigating setbacks caused by weather or access.

Today’s products and systems in the storm and sanitary space can vary greatly.

For internal pipe and sewer corrosion repair, one option is cured-in-place pipe (CIPP). With this method, once crews have begun installation, the only option is completion. Stopping mid project due to rain would mean removing entire sections and starting over. In order to avoid a setback of this magnitude, installations must be planned during stretches of foreseeably dry forecast: a difficult task in itself. Fortunately, there are options to help overcome some of the many challenges that can result in massive delays or cost upwards of hundreds of thousands of dollars.

Where a wet weather event can be responsible for the total loss of a CIPP installation, which could cost upwards of a million dollars in a large-diameter pipe application, a product such as Milliken Infrastructure’s GeoSpray® geopolymer mortar spray provides substantially more flexibility and the risk of product loss carries far less weight from a financial perspective. A major benefit of GeoSpay® geopolymer is its ability to allow crews to start and stop work at any time. This means if rain is in the forecast, work can be halted, and the proper precautions can be taken to save any applied product. In the case that any product is damaged by rain, damaged sections can simply be cleaned away and re-applied, costing significantly less compared to tearing out and replacing a complete CIPP application.

Access to pipes in need of repair can present further challenges as well and add cost to projects that geopolymer mortar systems can circumvent. Using a 72” pipe as an example, if access can only be gained through a 36” manhole, equipment for a GeoSpray® application can easily be delivered to the pipe through the manhole. A bag containing material for a CIPP application of that size requires excavating of the manhole in order to deliver the equipment to the repair site. For sites with no traditional means of entry, such as a manhole, the footprint for a topside GeoSpray® application construction zone may be as short as 60 feet long and take up only a single lane of traffic. CIPP could take up four or five times that much space and increase the burden on public motorways as well as increase construction costs.

With the significant potential for loss — whether it is of time, product or money, it is certainly worth considering multiple repair options for storm and sanitary applications. Milliken Infrastructure’s GeoSpray® geopolymer system allows for faster installations at a lower total cost that shouldn’t be ignored.
