Volvo’s B series
Volvo’s B series range of EC crawler excavators has been designed to work on some of the toughest terrains under construction. The B-Series crawler excavator range is one of the most diverse in Volvo CE, with the product line stretching from the 13.4 t (29,529 lbs) EC140B to the new 70.3 t (154,980 lbs) EC700B. Creating a low maintenance machine was a key design priority of the B-Series, and all models in the range – EC140B, EC160B, EC180B, EC210B, EC240B, EC290B, EC360B, EC460B and EC700B have been prescribed a variety of features that ensure maximum productivity with maximum uptime. Volvo has achieved this by fitting each machine with an array of advanced technical and ergonomic features as standard.

Hydrostop Restore & Protect System
Kryton International Inc. has developed a new three-step restoration and protection system for above-grade concrete structures. The Hydrostop Restore & Protect System greatly extends the useful life of aging concrete infrastructure and buildings.
The first step in the system uses a non-shrink waterproof grout to repair cracks and defects at the concrete surface. The product employs Kryton’s original crystalline technology and is named Hydrostop Grout. Once the substrate is repaired, the entire concrete surface is coated with a polymerized, cementitious slurry called Hydrostop Coating. This layer provides a durable barrier against water and chemical intrusion and improves the concrete’s overall aesthetics. The third step creates a long-lasting water repellent effect on the concrete surface by using a high quality blended silane-siloxane sealer called Hydrostop Sealer.
