CTS®/IBO® Hollow Bars
Our Geotechnical division stands on the shoulder of Horst Aschenbroich. With Con-Tech Systems, he introduced the CTS®/IBO® hollow bar systems into the market. We are offering the same system. We also supply strand anchor materials, namely steel strand, plastic sheathing and accessories, as well as hydraulic jacks.
CTS®/IBO® Hollow Bar System:
• Hollow bars are commonly used as Soil nails, Anchors and Micropiles.
• Each CTS®/IBO® hollow bar heat is tested in a certified North American Lab. The test certificate is provided with every shipment.
• CTS®/IBO® hollow bars are available in low carbon steel.
• CTS®/IBO® hollow bar couplers come with a middle stop.
Production Benefits:
• Single step casing free operation significantly improves productivity.
• Suitable for difficult and restricted access situations.
• Ability to use smaller drilling rigs reduces mobilization costs.
• Dramatically increased production rates.
• Permits top down mini jet grouting in saturated clays and silts complete with reinforcing bar.
• Remote de-coupling unit facilitates underwater piling from barges or drill platforms.
• No harmful vibrations or noise.
• Minimal spoil.
Geotechnical Benefits:
• Extremely low settlement characteristics.
• Enhanced mechanical bond with surrounding ground (ground improvement).
• Minimal disturbance during installation.
• Works in compression and tension.
CTS®/IBO® Hollow Bar System Technical Data
Hot Rolled Thread Bars
•FCS Can offers hot rolled thread bar. Grade 80 and 100 bars are produced in Canada.
• Main application of Thread Bars are:
- Geotechnical Applications: soil nails, micropiles, pre-stressed rock and soil anchors;
- Mining and Tunneling: anchors for roofs and side walls.
• Hot rolled Thread Bars are one of the strongest, simplest and most robust steel systems in the industry.
• The continuous hot rolled thread along the entire length of the bar allows the bars to be cut, spliced and anchored with couplers or nuts at any point along the bar.
• The two flat sides on the bar eliminate jamming of nuts and couplers.

and bar anchors.
• Sizes range from 25 ton to 800 ton.
• Calibrated rental kits include jacks, hydraulic pumps, gauges and hoses.
• Carbon fiber light weight jacks are available for sale.
• Please call us with your specific requirements.
Monostrand Jacks 25T
Our Monostrand Jacks were developed by Con-Tech Systems. FCS Can Ltd. has taken over the distribution and support.
Typical Applications:
Our monostrand jacks are dual acting and have a 76mm [3”] stroke and a max load capacity of 50 kips. They were specifically developed with mining in mind. They can be used to stress single strands and up to 25mm [1”] diameter solid bars. They can also be used to synchronize the individual strand tension on large strand anchors before stressing.
Flow Control
Air-Operated Pinch Valve
Install hollow bar micropiles or tie-backs under positive water pressure – without lowering the water table.
The Air-Operated Pinch Valve is a compact valve that seals around the hollow bar during drilling and grouting. Connected to a compressor, it inflates a durable rubber insert that grips the bar and holds back groundwater, keeping installation and grout placement controlled. Once the grout has cured, the valve is removed and the bar is ready for the head assembly.
Benefits:
• Works under positive water pressure – seals around the bar during drilling and grouting
• Eliminates or reduces dewatering – saving time, cost and site disruption
• Safe, controlled operation – a secure seal while the bar advances and grout is injected
• Simple to use – minimal training required
• Sustainable – avoids the environmental impact of dewatering
Typical Applications:
• Tension micropiles – resisting uplift in foundations and retaining structures
• Compression micropiles – load-bearing support for new or existing structures
• Tie-back anchors – for secant pile, diaphragm and sheet pile walls
