We are excited to offer our customers Karbon Bar! Karbon Bar is almost 4 times lighter than comparable diameter steel rebar for easier and safer transport, loading and installation.   It’s also much stronger than steel rebar making it great for slab curling and flexing. Tougher material is more resistant to alkalis, acids and rust! We are proud to offer both the 12mm and 10mm bar. This bar has a longer working lifespan, lower delivery, handling and installation costs (due to its light weight). Other benefits include: Stable pricing No thermal conductivity No electromagnetic interference

Rolair has been engineering and producing the finest compressors in the industry for 60 years! Located in the heart of Wisconsin, they have built quite the reputation for themselves providing professional contractors with compressors of utmost quality and craftmanship.  At Arco, we offer the FC2002 Double Tank Compressor and the JC10PLUS Single Tank Compressor. In this blog post we will go over some of the specifications of these two models and how to choose between a single and double tank compressor. Single Tank Compressors Single-tank air compressors generally have smaller storage capacities than double-tank compressors, which makes them a more...

Waterstop History To accommodate varying pressure and movement, most thermoplastic and rubber waterstops come in different extruded profiles, widths and thicknesses. For years the most widely used waterstops were those anchored by having a dumbbell shape at each end, creating a ‘cork-in-the-bottle’ seal when the joint opens. However, this seal is less effective at small joint movements and wider movements. To overcome these issues, BoMetals has manufactured profiles with multiple raised ribs to improve anchoring and sealing performance.  Choosing Waterstop Size  Waterstop size (width) is determined by the expected head of water pressure to be encountered at the joint. The...

The Occupational Health & Safety Administration (OSHA) reports that over 4,000 workers were fatally injured on the job and that one in five of those deaths were related to construction workers. The leading causes of these accidents rest in three categories.

It’s that time of year again. As we begin to hit the heat of summer, it is important to think about proper concrete placement practices to combat the heat. But first let’s look at why hot weather is a problem. Concrete sets as the cement hydrates. Hydration is an exothermic reaction, meaning it generates heat, and that reaction goes faster when the concrete is hot. So the main concern with the concrete's strength and set time isn't really the air temperature but the concrete temperature. When cement hydrates it sucks up water and grows crystals around the aggregate particles. When...
