Consumption Of Injection Materials
Injection Material Consumption Calculator – Forecasting and Optimization
The injection material consumption calculator is a tool designed for engineers and contractors who want to estimate the consumption of injection materials for a specific project. Thanks to this tool, it is possible to plan the required amount of materials, minimizing the risk of shortages or surpluses and optimizing both costs and work time.
How does the calculator work?
The calculator requires a few key parameters of the structure and the injection process:
- Length (of a crack / expansion joint / etc.) – [m]
Enter the length of the crack (fissure) or expansion joint to be injected. This parameter defines the scope of work and affects the calculations regarding the amount of material needed for filling. - Width (crack / expansion joint / etc.) *may use digits after the decimal point 0.01 – [cm]
It is possible to enter a value with an accuracy of up to two decimal places (e.g., a crack width of 0.01 cm or an expansion joint width of 3 cm or more). - Thickness of the structure (wall / ceiling / floor / etc.) [cm]
Provide the thickness of the wall, ceiling, or floor you plan to inject. You can also enter a value for the expansion joint space.
The calculator will display the first calculation: TOTAL filling with construction material [L] - Number of packers per linear meter (items)
Usually, this is 8–10 packers per linear meter.
You can also apply a result based on the thickness of the structure and the crack width (the next packer positioned at 50% of the wall thickness on the opposite side—though this depends on the crack width). If it’s an expansion joint, the packer is an observation point and could be 1 pc per linear meter. However, for hairline cracks, a test injection should be carried out to determine the appropriate parameters for distributing the injection packers. - Select the packer diameter:
in the range of 8 to 14 mm. The larger the diameter, the larger the volume of the drill hole, which affects resin consumption. - Drilling depth [cm] -> can be found in “crack drilling”
This value can be determined using the crack drilling calculator, which analyzes the angle and depth of the drill hole for different intersection points of the crack.
The calculator will display an auxiliary calculation: “ml” needed to fill one hole. - Enter the number of pump cleanings
This allows you to estimate resin and cleaner losses during pump cleaning and maintenance. - Length of the injection pump hose [cm]
The length of the injection pump hose determines the amount of resin and cleaner that remains in the system during equipment cleaning.
What do we get after entering the data?
- Amount of injection material needed to fill the structure (in liters)
The calculator automatically converts the length, width, and thickness of the structure to provide the total amount of material required for injection. - Material consumption for filling the drill holes
Based on the packer diameter and drilling depth, the calculator computes the volume of resin (in liters) needed to fill a single injection hole. - Material losses resulting from pump cleaning
Depending on the hose length and the number of pump cleanings, the tool indicates the amount of resin used for maintenance and downtime. - Number of injection packers
The calculator calculates the total number of packers needed to perform a complete injection, based on the specified spacing per linear meter. - Cleaning agent (in liters)
You receive a forecast of the amount of cleaning agent needed for maintenance and flushing the pump system. - Forecast of total injection resin consumption [L]
To convert liters of injection resin, acrylic gel, and other ResinBau products into kilograms, use the “Converter L->KG” calculator.
*Remember that the calculator does not determine the free expansion foaming of injection foams but only converts specific resin liters to kilograms.
Why is the calculator invaluable for injection planning?
- Optimization of materials – Avoid excessive resin consumption while preventing material underestimation.
- Forecasting in calculations – The calculator takes multiple variables into account, increasing prediction accuracy.
- Minimization of losses – Factoring in cleaning the system helps reduce unnecessary resin loss.
- Easy project adaptation – The ability to input various parameters makes the tool universal and adaptable to different types of structures.
- Direct data for the engineer – All calculations are presented in a clear manner, ready for on-site implementation.
Practical tips:
- Remember these are estimates – Actual consumption may differ due to the quality of the structure (e.g., cavities, defects in concrete) and unexpected resin leaks.
- Include a margin of error – It is always advisable to round up the forecast values to avoid material shortages.
- Carry out a test injection – This will help assess the actual material consumption over a small section before fully implementing the work.
The injection material consumption calculator is an invaluable tool for any contractor, enhancing planning precision and efficiency in injection projects.
