Shotcrete and Gunite

Whether you have straight or curved applications,  Shot-form will save money on every shotcrete or gunite project.

Advantages over 
wood or modular forms:

  1. Forms Easily: Shot-form easily forms into multiple configurations to accommodate curves and unusual shapes. To make corner bends, ribs are notched to a 90-degree angle by making two 45-degree cuts, leaving the mesh between the ribs intact. By bending the remaining mesh to the desired angle or radius, a perfectly formed corner or shape is created. Curves form easily in a direction parallel to the ribs. A full circle tube can be formed with Shot-form. Such a wide variety of form shapes are possible that it is impossible to describe all the flexibility this product offers. Many more shapes are attainable using Shot-form than by using other materials such as wood, steel or plastic. Multiple sections of Shot-form can be joined end to end with a 3-inch to 4-inch lap. End laps should always be braced with a support. To accomplish a side lap, over lap one or two ribs.
     
  2. Easily Attaches to Reinforcing Steel: Shot-form used as a backstop for shotcrete or gunite is most often attached directly to the reinforcing steel grid using tie wire. Since one can easily see through Shot-form, tying Shot-form to reinforcing steel is easily accomplished. Some contractors report a 40% saving in forming costs.
     
  3. Excellent Steel Coverage: Shot-form greatly reduces the amount of rebound during the shotcrete process, concrete build up occurs quickly. This helps to assure excellent coverage of all reinforcing steel. Remember too that Shot-form allows for visual inspection of the shotcrete application from the backside of the form, when accessible. This insures that no voids have been created.
     
  4. Cuts to Size Easily: Shot-form is packaged in five sheet bundles that are wire tied together. Single or multiple lengths or pieces can be cut utilizing a circular saw with an abrasive metal cutting blade. Tin snips or metal shears are used to notch small areas or ribs. Shot-form is manufactured from high strength steel and can be formed into a variety of shapes, performing well in tight curves and bends.
     
  5. Easily Penetrated: Shot-form can easily be snipped (sheared) or punched to accommodate penetrations such as rebars, conduit, or dowels. Often a sharpened length of rebar is employed for this procedure.
     
  6. No Stripping Required: Shot-form is a stay-in-place concrete form that requires no stripping. This means that you can leave the pry bar in the truck. Nothing is more labor intensive than prying plywood out of tight corners after a shotcrete application. Shot-form provides not only a labor savings in stripping cost, but also saves time and money that would be spent cleaning, oiling, moving and storing the plywood forms. The cost of form release agents is also saved.
     
  7. Shoot One Side Today and the Next Side Tomorrow: Shot-form stays-in-place and is never stripped, allowing the contractor to shoot one side today and the other side tomorrow. Minimal set up time is necessary because no stripping is required.  The contractor need only wait for the first shoot to be stiff enough not to be disturbed by the pressure of the second shotcrete application.
     
  8. Saves concrete: The contractor, utilizing either the dry or the wet shotcrete process, will realize a savings in concrete usage and gain speed in the application process due to the greatly reduced amount of rebound that occurs when using Shot-form. Concrete readily adheres or bonds to the openings in Shot-form. This reduced rebound increases productivity and saves material. A saving in material translates into savings in money.
       
  9. Less Back Filling is necessary: Shot-form does not require stripping, therefore, the amount of backfill required in the smaller area behind the form is greatly reduced. Because the contractor does not have access to the back of the form to strip, less area must be left clear behind the form. This saves excavation cost. Shot-form allows air to reach the back of the concrete sooner and promotes faster set up and curing, allowing back filling to take place sooner. This saves time and reduces equipment rental costs.
     
  10. Saves Time and Money: All of the above adds up to a savings of time and labor, which translates into financial savings on every project. The old adage rings true, "Time is money".

Shot-form will save you money on every project.
