The MAYBS bolt was developed to address both primary and yielding support with one product.

The product is patented and features a range that caters for between 7 and 9 tons initial support load which when grouted produces a 10 and 14 ton system respectively. Yielding is then induced at 10 and 14 tons respective to each system. the system incorporates a unique grouting capability that has an option of a GROUT INDICATOR which will give visual indication of a pressurized system. this can only take place when the hole is fully grouted.


The MAYBS Bolt is a one pass system with immediate support and yielding ability.

It can be installed with mechanized bolters or manually

It has high energy absorption capabilities of up to 45 KJ

It has a full proof grouting system with visual indication for post grouting inspection

The installation mimics a conventional rock bolt with no additional requirements.
