About Us

Multi-Flow by Varicore Technologies Inc. is a comprehensive soil water management system.

Who We Are

Varicore Technologies, Inc. is headquartered in Prinsburg, MN. We are the parent company and manufacturer for the Multi-Flow and Multi-Flow LDVS product lines, along with various other brands of custom-fabricated machinery tailored to the HDPE pipe market. Varicore is privately held and has been for over 3 decades.

What We Do

Varicore Technologies was founded in 1993 with the consolidation of an equipment design and manufacturing company and a drainage company. Over the past 25 years Varicore’s focus has shifted to the production of a variety of fluid collection products and also design consulting services. Varicore operates from manufacturing facilities in Prinsburg, MN, with business offices in Willmar, MN. Follow us on Facebook or LinkedIn to see ares we are currently working in.

Multi-Flow

What is Mult-Flow?

Multi-Flow is a closed core geocomposite drain made from HDPE. The flow channels are corrugated for strength, perforated for rapid infiltration, and interconnected for redundancy and performance. The resulting product is strong, lightweight, flexible and an excellent conduit for fluids and gases. It’s rounded shape eliminates sharp edges, making it easy on liners.

Multi-Flow LDVS is a significant step ahead of other systems due to its propriety shape and method of connection. When combined with easy-to-use connectors and standard pipe sizes, the leak detection vent system outperforms other systems, and at a low cost.

1. System Layouts & Design

Typically, Multi-Flow LDVS is designed with a common-sense approach to gravity and slope. Following the contours of the pond or lagoons, collector lines are oriented in the direction that offers a path of least resistance to the high-point and low-point. Lines should be spaced for continuous coverage on 15 ft-20 ft intervals, making use of connectors and manifolds to achieve an efficient grid for collection and removal of fluids and soil gases.

2. Venting Design

Multi-Flow is installed under the liner to provide a flow path for gases and liquids preventing damage caused by lifting or tearing of the liner. The top end of the system is vented to the atmosphere or collected in a manifold. If desired, positive venting (blower units) can also be added to outlets to aid diurnal atmospheric pressure changes in removing gases.

Multi-Flow lines can be rolled out over the prepared surface and covered by the pond liner. This method avoids the need for trenching and it locates the Multi-Flow right where methane and other gases are most likely to accumulate. If a completely smooth liner is desired, installers can create a depression without piercing the liner in many locations.

3. Drainage Design

The low point of the Multi-Flow System is typically connected to piping which leads to a pumping or monitoring pit, or discharge location. This pit, located outside of the containment area, allows ground water to be removed from under the liner with a variety of pumping/piping options. Most importantly, it offers a leak detection/inspection point as well.

4. Leak Detection

Multi-Flow LDVS provides a leak detection option. Simply connect the drain outlet to a sump pit with a pump and any required pumps, monitors or telemetrics. Then, the users may monitor and test any fluid below the liner, alerting them of problems before they become worse and/or more costly.
