Three Stars Galaxy International L.L.C offers expert installation of grouted and mortared riprap systems — a highly durable solution for slope protection, drainage channels, seawalls, and embankment stabilization. Our civil engineering team ensures long-term erosion control through precision placement, quality materials, and cement-based bonding techniques.

🛠️ What is Grouted / Mortared Riprap?

Grouted Riprap is a layer of stones or boulders placed on a slope and bonded together with a cement grout to form a solid, water-resistant surface. It prevents soil erosion, absorbs water impact, and stabilizes the ground.

Mortared Riprap uses a mortar mix to permanently bond stones in place, offering even greater durability, especially in high-flow or high-impact areas.
