Concrete Repair Product Volume Calculator

Crack injection or concrete floor repair product volumes can be calculated using our product volume calculator in imperial or metric the metric is further down the calculator column page. Things to consider before using our calculator.

1. Wall cracks in concrete tend to be wedge-shaped as force may be pressing on the wall from one side such as a horizontally cracked basement wall and this will affect the volume of the product may be actually less than the calculator shows.

2. Very small wall cracks may not always extend to the exterior of the concrete so the volume of the product used will be a little less than calculated but is an accurate gauge of actual usage due to product loss.

3. Large Wall Cracks can create a situation that allows for uncontrolled product loss when a too low of viscosity is used and it simply saturates the soil outside the wall injection. This is why selecting the correct viscosity or changing viscosity during the repair helps with product loss especially with Epoxy as it does not expand and is filling the void until it cures. So when using the calculator always assume some product loss.

4. The difference in volume between different tube sets is because some are 1:1 ratio and each has a total volume of 600ml where a 2:1 ratio tube set product is only 450ml so more product is needed for this type.

5. All of the Polyurethane products expand but this expansion ratio is affected by the amount of moisture or water present inside the wall. Our calculator is showing values from actual usage from real repairs and is an average value. Product loss can also be affected by too much injection pressure or when an unknown void is encountered.

6. Epoxy and Polyurethane products are designed for concrete walls and should not be used on floors. If you wish to use on a suspended or precast concrete floor contact us so we can make sure you use the correct product for your situation.

Floor Crack Calculations

The calculators are reasonably accurate for all floor repairs as most breaks are even through the floor, both the 10-minute mender and E555 are compatible with sand as void fill for larger cracks.
