Product Details
Ecologic™ Injection Grout Product Description:
Ecologic™ Injection Grout is a specially formulated grout based on Natural Hydraulic Lime (NHL 5), containing NO Portland Cement, specialized clean aggregates.
- Type I Grout – This is a mixture of St. Astier NHL 5 and casein (particle size: 40 – 60 microns). It’s recommended use is for filling very fine cracks up to a width 1/16 inch.
- Type II Grout – This is a mixture of 1 part St. Astier NHL 5 to 1 part glass microspheres by volume (particle size: 300 microns) is recommended for use for fine cracks or voids between 10 mils (0.010 inches) and 1/8 inch.
- Type III Grout – Is a mixture of 1 part St. Astier NHL 5 and 1 part #100 or fine white silica sand by volume ( particle size: 600 microns) to be used for cracks or voids between 1/8 inch and 1/4 inch
- Type IV Grout – Is a mixture of 1 part St. Astier NHL 5 to 1.5 part blended aggregates by volume (particle size: 800 microns) to be used for cracks or voids between 1/4 inch and 1/2 inch
- COULINEX (Type V Grout) – based on NHL 3.5 it can be used on its own or with the addition of sand, depending on the size of the void. In fine injection work, it can be applied on its own or with very fine aggregate, depending on the size of the void. Used in stone statuary and monuments.
General Application:
Use non-staining clay, caulk or Duct Seal to temporally dam the bottom of the crack being repaired. As the Injection Grout fills the void space, allow to cure for a minimum of 24 hours before the removal of damming material. Avoid overflow and runs on the masonry when possible. Fill the void slow and steadily, using horse syringe (without the needle) for pure NHL grout with no aggregate, and use grout bag with any of the four grout types, until more materials can no longer be accepted. Repoint or patch the mortar joint or stone with appropriate compatible
materials.

Application: mix with a whisk for about 3 minutes adding water (7 – 8 litres per bag of mortar). If a normal mixer is used, mix for 5-6 minutes.
Dampen the grouting area to control suction (see Coulinex grout mix ).
The mortar fluidity and final mechanical performance depends on the water addition.
Injection and grouting are interventions that are site-specific. The above information is given to assist the specifier to evaluate the mortar type. Tests are recommended to verify that the product is suitable for the intended use.

I used this grout to infill a very small break line across the inscription on a gravestone (I do cemetery preservation/restoration work). I applied it with a small syringe and smoothed and cleaned up with a dampened makeup sponge. It worked great.
It does set up pretty quickly so if using it in a non-traditional way as I am do the job in small segments so it doesn’t set up before you can do your finish work.
Limeworks was kind enough to sell me a quart jar as I don’t (and won’t) need the amount in a standard container. I thought that excellent customer service.
