You’ve chosen Mountain Grout. You know the specific formulation you plan to use. Remaining questions tend to revolve around equipment and methods. Therefore, this post focuses on equipment recommendations on different types of jobs.
For crack injection, a high pressure pump is a must. The best option is usually an airless paint sprayer, such as a Graco 395 Ultra or a Titan 440i. However, if you want something under that price point, a manual bucket pump is almost always a better choice than a grease gun. Additionally, Mountain Grout Pump Flush is a must if you want to keep pumps working. Packers come in different shapes and sizes (3/8″ tap-in, 1/2″ mechanical, 5/8″ mechanical and more), but the best advice is to go with the one that fits the diameter of your hammer drill. Further, mechanical packers guard better against blow-outs. For more equipment recommendations on crack injection, contact a Mountain Grout Technical Representative.
On soil stabilization jobs, there is often no need for a high pressure pump or packers. Slow and steady is the name of the game. Installers need steel grouting pipes to drive into the ground to the desired pumping depth. Some mark the pipes every foot or so to help monitor the depths at which they pump. A pump that pumps ~3 gallons per minute (gpm) is ideal in most cases. Installers can use pumps that pump lower gpms, but it increases the labor cost.
