ROCK-XL
Expanding Grout Perfect For Hole Diameters of 1″ – 2″
Rock Busters is here to help ensure your project has all the tools and products you need to get the job done quickly and efficiently. Feel free to contact us for any questions.
ROCK-XL is our latest product brand on the market. Designed for large commercial projects where holes can be drilled from 2.5”- 5” in diameter, this grout works at a greater pressure and its slower set time reduces the risk of blowouts. The advantages are less drilling and less product required to do bigger jobs, saving you money.
Small cracks can begin to appear as early as 6 hours but waiting 3 - 5 days will result in more extensive and wider cracks. Expansion/cracking can occur for up to 2 weeks. In cooler weather, expansion and cracking is slower.
