Bridges

Hey everybody this is Marc with San Joaquin Gunite of Fresno and I’m talking about using shotcrete to  construct, repair or restore bridges with.  A bridge normally requires vertical repairs and is usually done with rapid set cement mix.  The normal company uses the manual lay-up method, but San Joaquin Gunite is not the normal gunite company and when contractors request shotcrete instead, that’s where we come in.  As long as the crew is experienced and applies it correctly, shotcrete makes for a viable solution.  Good surface preparation and the just right amount of water added to the mixture are extremely important

for making sure shotcrete bonds well to the bridge’s structure.  The way the shotcrete bonds with the old structure at the point of application dictates the longevity of the repair, so hiring the right crew to do job is just as important.  Thanks again everybody for your time.

Forming A Composite

Hey everybody, this is Marc with San Joaquin Gunite  of Fresno, California and today I wanted to touch on the process of forming a composite.  The formulation of a composite is not as simple as it may seem and following the performance guidelines and completing the project on the projected budget requires a team with strong collaborative efforts.  Materials supplier and contractor must stay in consistent communication so that the job is finished on the estimated time.  With mixture of either dry or wet shotcrete the nozzleman directs the application to help create various layers, giving the composite its thickness.  Some believe that because shotcrete is sprayed on in layers, it tends to have bonding problems with its structure, but others believe that because shotcrete requires less water than normal concrete, it has longer durability.  However it is common knowledge within the industry that shotcrete bonds well with concrete and helps form a complete composite.

Dry Mix Versus Wet Mix

The shotcrete application is a process that can be very complex.  After understanding the essential function of the structure and weighing out other external variables, the method for application is then chosen.  These variables are rebound levels, dust levels and properties such as bond strength and durability.  Though it is referred to as a dry mix, some of the material is dampened when poured into the equipment, while the wet mix is mixed up thoroughly with water.  To learn more about the process visit our social media links

San Joaquin Gunite’s Method Of Application

The method in which San Joaquin Gunite applies shotcrete depends on several variables.  Economics is probably the most important factor that is taken into consideration before the application even begins.  Economics is also a factor throughout the project, but the other important factors are heavily considered, which are: availability of material and equipment, site access and the expertise and preference of the contractor.  The difference between a dry and wet application are the point in which the blend comes into contact with water.  A dry application is shotcrete pumped out through the nozzle without the blend of water and the wet application pumps out shotcrete that has been blended with water.
