The type of grout pump required for the job - either manual or air-powered - is based on the complexity of the job. You will need to determine if you require a pump with a mixer attached as well, as some jobs may require it. For simpler jobs like leveling small sidewalk slabs and filling cracks, a manual pump will likely be sufficient. For more complex jobs, an air-powered pump will be more efficient. Complex and time consuming jobs can be done more quickly by using a grout pump with an attached mixer.
Typical Uses for Grout Pumps
Grout pumping is a valuable tool for ground remediation, also known as land remediation. This is the process of injecting environmental compounds into hazardous or contaminated ground to remove pollutants and/or prevent migration. This process protects humans and animals from contamination.
Remediation is required when it is discovered that the amount of contaminants exceed, or are in danger of exceeding, maximum levels for a particular resource (i.e., lead in drinking water). There are a lot of ecological and cost benefits to ground remediation.
Types of Ground Remediation
There are several hazardous materials which can contaminate the ground and create the need for grouting soil and remediation. Some examples include chemicals, oil spills, industrial waste, and gas leaks. There are several different types of ground remediation which can be used on hazardous materials. They are containment, treatment, removal, excavation and incineration.
Containment means isolating the material so that nothing can come into contact with it. Treatment means changing the material into something less hazardous while leaving it where it is. Complete removal is soil washing, a process which involves the material being washed out and removed. Excavation is digging up and removing the material and transporting it to another location, and then filling the area in with fresh dirt. Incineration is completely destroying the material by burning it.
