When working with shotcrete or gunite, your hose isn’t just a tool — it’s a critical part of the application process. Both materials are highly abrasive, and both require consistent, high-pressure delivery. Choosing the wrong hose can result in costly delays, product waste, or even safety hazards. Here’s what you need to look for when selecting a hose for shotcrete or gunite work:
1. Abrasion Resistance is Key
Shotcrete and gunite are both composed of cement, aggregates, and other hard materials. This makes abrasion resistance the single most important factor. Look for hoses with thick, durable rubber inner tubes specifically engineered to withstand heavy wear over time. Reinforced options with a highly abrasion-resistant cover will dramatically extend the life of the hose.
2. Proper Hose ID and Wall Thickness
The right inside diameter (ID) and wall thickness ensures proper flow and reduces pulsation. Typically, 1.5″ to 3″ ID hoses are used depending on the application and nozzle size. A thicker wall can help maintain shape and prevent kinking, especially when navigating tight corners or complex spray angles.
3. Reinforcement for High Pressure
Shotcrete is usually applied using high-pressure air, so your hose must be able to handle the PSI required without bulging or blowing out. Wire or textile reinforcement strengthens the hose and helps it maintain performance under demanding conditions. Be sure to choose a hose rated well above your operating pressure.
4. Flexibility and Handling
You’ll often need to maneuver the hose in tight spaces or awkward positions — tunnels, overhead applications, or vertical walls. A hose that is too stiff will slow you down and fatigue your crew. Look for a balance of strength and flexibility for better control and less strain on your team.
5. Secure, Heavy-Duty Ends
Your couplings need to be just as durable as the hose itself. Reusable or crimped heavy-duty hose ends will provide secure connections that prevent leaks or dangerous blow-offs. Be sure they are compatible with your pump and nozzle setup.
6. Length and Custom Assemblies
Avoid excess length that creates unnecessary pressure loss or trip hazards. Many suppliers — including Midwest Hose — offer custom hose assemblies tailored to your exact needs, so you can keep your workflow efficient and safe.
7. Safety Ratings & Industry Compliance
Always check that your hose meets industry standards for concrete and shotcrete applications. Pressure ratings, burst strength, and material specs should be clearly listed and match your equipment and project demands.
