Mastermix Culvert Bags consist of a specifically manufactured mix that is designed to give optimum strength of set over as short a period as possible, and to carry on and give a full set and cure over 28 days. It is also designed to be cost effective as in number of bags per square metre for the end user whilst remaining easy to handle. They weigh 25kg and most importantly are designed to achieve a square metre coverage of 17-19 bags m2. Our Culvert Bags have a lower constructed cost per square metre when compared with pre-cast concrete and crib walls. We are accepted and regularly used by companies such as Fulton Hogan, Higgins, Fletcher Forests, McBreen Jenkins, Downer NZ LTD, and numerous Local Bodies so if you are in the market for a proven product then contact our Technical Department for more information.

- Cheaper than pre-cast concrete and crib walls
- Biodegradable polypropylene bags
- 25kg for ease of transportation
- High strength
- Low UV resistance
- High strength – 20.0MPa after 7 days and 30.0MPa after 28 days
|Product Performance||As part of our commitment to developing the best products for your projects, Mastermix has maintained a 20 year history of rigorous testing via internationally recognised laboratories. We pay top dollar to put our products to the test so you don’t have to. OPUS Laboratory Results independent laboratory tests carried out in accordance with NZ3112 and show that compressive strengths will be achieved as follows: 🗸 + 7 days – 20.0MPa 🗸 + 28 days –30.0MPa|
|Packaging||25kg polypropylene bags – bag size W400mm x L300mm x H100mm – approx 17 bags per m2 – 40 bags per pallet|
|Placement||🗸 Stack as though you are building a brick wall. Batter the bags back approximately 10mm, this helps to lock the bags in 🗸 Culvert Bag’s need to be staked by either using basalt rods, y-post or steel rods. Place the stakes every second bag and start at the 3rd level 🗸 Bags may be laid flat on the entrance and exit of the pipe to prevent scouring 🗸 They can either be watered down during placement or left to the elements to set them|
|Warranty||As part of our commitment to delivering the best customer experience throughout the project lifecycle, Mastermix Director Steve Douglas personally reviews each warranty request. Each Warranty period is awarded at our discretion and will only be considered where approved Mastermix product applicators are used.|
