At Three Stars Galaxy International L.L.C, we offer expert supply and installation of Loose Riprap – a highly effective solution for protecting slopes, embankments, waterways, and coastal areas from erosion. Our civil engineering team designs and installs riprap systems using durable, angular stone to provide long-term ground stabilization in both dry and water-impacted areas.

🛠️ 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.

🛠️ What is Loose Riprap?

Loose Riprap is a layer of large, irregularly shaped stones placed freely (without mortar) on embankments, riverbanks, culverts, or drainage channels to resist the force of water, wind, and soil movement. It provides flexibility, permeability, and natural drainage, making it ideal for both temporary and permanent erosion protection.

📍 Common Applications
