Understanding Waterstops and BoMetal Waterstop Specifications

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...

Hot Weather Concreting

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...
