Foam cubes are an easy and cost-effective way to plug holes underground instead of using plastic cones.
Foam cubes help to keep holes from filling up with silt and debris and reduces fallback. The product is often used in areas where there is a lot of activity from vehicles and blasting. Pressure from blasting does not generally blast cubes from holes, therefore it is not necessary to continually replace them. The product is reusable and helps to ensure that holes drilled remain clean and ready for the blasters to load at a later date. Prep time is greatly reduced along with redrills.
