KIMROC, pioneers in innovation in tunnel pre-support.

KIMEX®NLS Micropile System for tunnel prebreakthroughs.

KIMEX®NLS MICROPILE SYSTEM

At the core of our solutions is the innovative NLS system, as well as the brand new Variable Nipple systems, with or without locking where safety requirements are not debatable.

This advanced technology enables fast and efficient drilling with low torque requirements, setting new standards in tunneling pre-support.

Efficient sweeping, or easy repositioning together with KIMEX®NLS technology ensures exceptional performance even in the most difficult geological conditions.

MAIN CHARACTERISTICS

HIGH SPEED DRILLING

Ensures fast and accurate drilling, even in challenging terrain.

LOW TORQUE
REQUIREMENTS

Reduces equipment stress and improves energy efficiency.

ADVANCED THREAD TECHNOLOGY

Ensures secure connections and minimizes the risk of clogging.

UMBRELLA MICROPILE TECHNOLOGY

Our umbrella micropile technology, also known as forepoling, revolutionizes tunnel stabilization.

This method involves drilling with sub-horizontal micropiles in front of the excavation face, creating a protective arch that absorbs pressure from the surrounding rock and soil.

MAIN CHARACTERISTICS

SOIL STABILITY

Ensures that the tunnel face remains safe, minimizing construction risks.

ADAPTABILITY

Effective in various geological conditions, from soft soils to hard rocks.

EFFICIENCY

Reduces the need for extensive support structures, speeding up the construction process.

screw technology

Introduced in 2021, our KIMEX® NLS thread technology sets a new standard for semi-automatic threading in tunnel construction.

Designed for maximum strength and durability, the thread features a trapezoidal profile that improves the safety of connections.

MAIN CHARACTERISTICS

HIGH LOAD CAPACITY

The larger thread root supports heavy loads and resists deformation.

EASY HOOKING

A 7 mm taper simplifies connections, guaranteeing secure assembly.

LOW TORQUE REQUIREMENT

Reduces equipment wear and speeds up installation.
