The air temperature by itself isn’t the determining factor on whether you should pour concrete. The temperature of the air, the humidity level, and the wind speed, the temperatures of the surface where you are placing the concrete, the water and the dry concrete in the bag all play a huge part and must be taken into consideration. The air, wind and humidity are pretty much beyond your control but some of the others you can influence. It is important to remember that the temperature of the mixed material is as important as the air temperature. more

The first thing that pros do in the winter is use hot water. If you use hot water and keep the dry product in a heated area of your house or garage until you are ready to use it this will greatly accelerate the set of the concrete. You can buy products designed to set quick such as Sakrete Fast Setting Concrete. It will not set as fast as the literature says it will if the air temp is anywhere near freezing but it will set much faster than normal concrete. You can also buy additives to accelerate the set. The only concern here is the type of accelerator. If it contains calcium chloride and your concrete will contain rebar or metal wire mesh, the chlorides will attack it and produce rust. This will ultimately crack your concrete. When concrete sets it gives off heat. Not like frying an egg but there is a slightly exothermic reaction (a big word for a reaction that gives off heat-use it to impress your friends). You can use this to your advantage by covering the concrete (after it has stiffened) with a blanket. They sell blankets for this purpose so your kids won’t have to sleep in the cold. You could also put up a tent or lean to and put a space heater inside. [links]

If this doesn’t quite give you specific enough guidelines, maybe we should define what moderate temperatures are? This is open for debate and involves other factors but in general if the air temperature is between 50° F and 90° F you should be safe. You can safely place concrete outside of these limits but you need to do a few things to make sure your job won’t turn into a nightmare. more

Cold Weather
If the air temperature is below 32° F I would really advise that you wait until warmer weather or call a pro. Unless you want to erect a tent with a space heater or steal your spouse’s electric blanket off the bed, this will only lead to trouble. If it is so cold out that the ground is frozen don’t pour concrete under any circumstances. The biggest issue when pouring concrete when the air temperature is just above freezing is the night time temperatures that will follow. Concrete sets much slower in cold weather. It is critical (I’m going to repeat that- critical) that the concrete sets before it is exposed to freezing temperatures. The problem is that when water freezes it takes up more space in the ice phase than it does in the liquid phase. When all of the water that you used for mixing freezes, it expands, causing your concrete to crack. The key is doing what you can to make sure the concrete sets fast enough to prevent this. more

Because of the timing of this recent bout of potholes, it took some time to find a supply of hot asphalt. None of the asphalt plants in New Hampshire were open in January. Initially, Exeter used what is known as cold patch to temporarily fill in holes. Cold patch is not ideal for long term pot hole repairs as the stickiness that helps it fill in the holes also causes it to get pulled out when it sticks to car tires. Thankfully for the local pothole patrol, an asphalt plant in Dracut, Massachusetts opened up last week, which enabled them to get some more permanent patching asphalt. here

Residents were urged to report potholes to the DPW and Jay said that in most cases a crew was able to respond within three hours. In some cases, like that of a large pothole on Portsmouth Avenue near Foy Insurance, crews have responded at night.

Between the crazy polar vortex and January thaw weather of recent times, I found myself in a real post-holiday slump last week. The beautiful snow was mostly gone, leaving us with no option to snowshoe or sled at the Raynes Farm. The ski areas were open but seemed to be mostly covered in ice and slush.

So what's the trick to successful pothole repair? [links]

These changes in technology have added to ease of application. Older benonite applications were conducted by skilled workmen through spraying and troweling applications that required uniform thickness. The current benonite panels are applied by laying the panel on the substrate, properly lapping the panels and nailing them to the substrate. here

Proper drainage can be achieved by adequately sloping the horizontal substrate a minimum of 1 to 2 percent to allow proper flow to the drains. The drainage course medium is either gravel or plastic drainage panels. more

Mud mats: Below-grade waterproofing typically begins on grade at the mud mat. A mud mat is an unreinforced concrete slab or gravel bed that is applied under the foundation. The intent of the mud mat is to prevent groundwater from entering the slab surface. Buildings constructed at sites with high water tables should always include a mud mat.

[matador]

These systems allow for both above- and below-grade application, including planters and split-slab construction. They are not resistant to ultraviolet weathering and cannot withstand foot traffic, so they should not be applied on exposed areas. When LAMs are applied on horizontal applications, a sub slab must be in place for application of the membrane. A topping of concrete, tile or other hard finishes is required. LAMs are applicable over concrete, masonry, metal and wood surfaces. more

The type of material used in the system determines the application methods. Waterproofing membranes include:

When recharging your Yeti, or any battery for that matter, you’ll notice your battery quickly filling up in the beginning, then very obviously slowing down when trying to charge up the last several percentages. Why does this happen? It's called the stadium effect. Think of how quickly a stadium fills up when the doors first open – there are hundreds of open seats so it’s easy to find the one you want. Eventually though, there are only a few open seats scattered about the stadium and people must maneuver around to find the spot they want. Thus, filling those seats takes longer. The same theory applies to recharging your Yeti power station. At first, it’s easy for energy to flow in and take up empty space. As time goes on and there is less space available, it takes longer for the energy to fill in the holes. here

Try to keep your Yeti power station topped off at all times. This is an easy trick to always ensure your Yeti is ready for anything; however, it’s also the number one thing most Yeti owners forget to do on a regular basis. In addition, we recommend using your Yeti periodically to keep its battery in best working condition, even if you don't necessarily need a constant source of big power. For example, we suggest getting in the habit of using your Yeti as your phone charger each night. more

Whether it's backing up essential home circuits in a power outage or hitting the road in a van or RV, the ways in which people use a Goal Zero Yeti Power Station vary greatly. However, no matter what your usage might be, Yeti care and maintenance remains the same. We’ve pulled together a few tips and tricks to help you get the most out of your Yeti experience, and keep your portable power station running through whatever comes your way.
