Access to an independent water source is a major advantage, but drilling a deep borehole is a complex engineering challenge. Long-term success depends 100% on the materials used, as the pipes must withstand extreme geological pressures. Here, Valrom Industrie stands out from the competition with its VALSpring system – high-performance unplasticized PVC (PVC-U) casing.
The Undeniable Advantage: R8, R10, and R16 Resistance Classes
Unlike standard casing on the market, the VALSpring system was designed to meet the most rigorous depth requirements. We offer three distinct resistance classes, adapted to each project:
-
Class R8: Recommended for boreholes with a maximum depth of 45 meters.
-
Class R10: Ideal for medium-depth wells, safely reaching up to 90 meters.
-
Class R16: Our top-of-the-range, which clearly differentiates us in the market! This class allows for safe casing at an extraordinary depth of 300 meters, offering massive resistance to soil crushing forces.
PVC-U: Why give up steel?
Traditional metal casing is prone to corrosion, rusting over time and compromising water quality and pump integrity. VALSpring pipes, made entirely of unplasticized PVC, are absolutely insensitive to corrosion and resistant even to saline groundwater or chemical agents. With a proven lifespan of over 50 years , PVC-U does not release toxic compounds, making it the ideal material for drinking water networks.
Precision Filters and Secure Installation
The system includes pipes with threaded sockets (DIN 4925), eliminating the need for welding or glue, ensuring quick and aligned installation. For water abstraction, VALSpring offers PVC filters with precisely cut slots, which block sand from entering the pump.
By choosing VALSpring, you invest in a borehole that not only withstands record depths but also ensures pure water for generations to come.
Frequently Asked Questions (FAQ) – VALSpring
1. To what depth can VALSpring pipes be installed? The maximum depth strictly depends on the chosen pipe’s resistance class: 45 m for class R8, 90 m for class R10, and up to 300 m for class R16.
2. What does the maximum level difference “h” represent during operation? During borehole cleaning or pumping, the difference between the water level inside the pipe and the liquid level outside must not exceed certain safety parameters: 15 m (for R8), 30 m (for R10), or 120 m (for R16). Adhering to this difference prevents casing collapse.
3. Is the water from a well cased with the VALSpring system safe for consumption? Yes, 100%. PVC-U is universally accepted for drinking water distribution because it does not release toxic compounds into the water, does not rust, and does not alter the taste.
4. How is the pipe packing done correctly? Packing with pea gravel is done in counter-current, introducing water into the PVC pipe while the gravel is gradually released, in small quantities, from the outside, to protect the system.
