Uses for Slurry and Grout Pumping Equipment

Sometimes surfaces are unsuitable for construction because beneath the top layer, the soil or rock contains voids or porous matter. To stabilize these areas, contractors use grout pumps to fill the voids with soil grouting or rock grouting material.
Sometimes surfaces are unsuitable for construction because beneath the top layer, the soil or rock contains voids or porous matter. To stabilize these areas, contractors use grout pumps to fill the voids with soil grouting or rock grouting material. This also makes the foundation more water resistant, preventing that ground from undergoing dramatic changes or shifts after construction. Different types of grouting are used to suit different environments and projects. Also depending on the conditions of the project, the process of injecting grouting can be simple, using a manual hand pump, or complex, relying on highly mechanized processes.

Contractor Solutions for Grouting Projects

When dealing with unstable or highly porous material, it is important to consult a contractor about what types of grout will work best and be the most cost-effective for your project. Finding this solution requires knowledge of grouting types, knowledge of soil types, availability of various grouting techniques, and experience handling the cost of different techniques. For highly technical situations requiring grouting, contractors may even subcontract to others with a greater degree of specialty in the area.

Types of Grouting Techniques and Grout Pumps

Grout pumps and slurry pumps can release grout into a void at high volume or under high pressure. Some pumps are used to transfer liquid ingredients, such as wet cement, while others contain more solid fills and more viscous or abrasive slurries. Generally, grout pumps are most effective when depositing grout only a short distance from the pump. The longer the hose, the more likely it is to be damaged because more material passes over it. Also, voids can be filled more accurately when they are only a short distance from the pump – the process is more controlled. However, due to different types of terrain, ideal conditions are not always possible. In these cases, it is important to have a higher pressure pump to get a more accurate spray of material that will be able to travel farther. Some pumps can be attached to hoses a mile long for long-distance grout deposits.

Some areas may also be in sensitive neighborhoods or by residential property. For the convenience of those around the construction site, some models of grout pumps are designed to reduce noise from the motor and action of the pump. These pumps are powered by electricity instead of a gas motor.

Jet grouting is another form of grouting, forming its own specialized subcategory. This technique relies on exceptionally high pressure (up to 6,000 psi or 40 MPa) to erode, replace, and mix cement soil into the existing material. The drill of a jet grouting pump rises and falls as well as rotates so that the horizontal stream of jet can mix all around with the surrounding soil.

Purpose of Grouting

Grouting and jet grouting is often used to stabilize contaminated soil, create groundwater barriers, and support distressed foundations. These are important applications in both construction and environmental protection. These techniques are also often applied in areas that are inaccessible to other stabilization techniques.
