Concrete sealants are products designed to inhibit and/or prohibit liquids from being absorbed by concrete. Concrete, contrary to popular belief, is actually a porous material. It can and does absorb water and other liquids. Some of these liquids can have dissolved materials (salts, acids, etc.) which can severely harm the concrete. Water can enter concrete and freeze. Water which freezes expands by approximately nine percent. This expansion can literally tear concrete apart. It is a good idea to apply a concrete sealant to avoid such problems.
Problem solving is the nature of our world. Researchers and scientists create things, methods or new products only to find that a secondary problem develops as a result of the initial solution! This happened with the newer high efficiency furnaces. These furnaces deliver 90 percent or more combustion heat to your home, compared to old coal furnaces which only delivered about 50 percent. Here are some things to keep in mind for hot water heater venting into old chimneys.
Many old homes in the United States have aged masonry chimneys with gas furnaces that use the chimney as a vent. Replacing such appliances will leave you with an oversized chimney and draft problems. With stainless steel alloy chimney liners, you can solve this problem. The following tips when talking to companies will count if you're making this adjustment.
The following resources are for chimney construction, design and maintenance. If you need to fill a large space around a chimney crown, try the following list of manufacturers who make cement stable silicone caulks. Also, ChimneySaver's CrownSeal, while not a project you can do at home, can help you with your chimney repair without having to start from scratch.
Chimneys. Every time my kids watch Mary Poppins, I think of chimneys. Imagine how many millions of chimneys there are in the USA: millions and millions. Heck, I've got two on my own house and I've seen houses with as many as four and five. Each chimney must be properly crowned with a gap between the flue liner and caulked with a cement stable sealant. You can also protect your chimney by installing a chimney cap to reduce weather damage.
Concrete driveways tend to be very white. Blacktop or asphalt driveways tend to be very black. Is there an alternative? You bet there is - it is called a tar and chip driveway. If you have access to colored rough gravel in your area, you can have a low cost colorful driveway that looks like a country road. Browns, grays, pale greens are all possible. In fact, if you are fortunate to have a resourceful gravel supply company you can even blend colors. My own tar and chip driveway is a mixture of light and dark brown stone chips.
For a proper installation of your tar and chip driveway paving, check out this inexpensive literature from the National Asphalt Pavement Association and the Asphalt Institute.
Tar and chip driveways are attractive, cost less and require little maintenance. Get a contractor to do the installation for you. Installation during the hot, dry summer is the best weather for the asphalt and chips to adhere, and a standard air blower removes debris without removing the chips. Here are more do's and don'ts of installing and maintaining a tar and chip driveway.
If you want to have long term success with patching holes and cracks in your blacktop or asphalt surfaces, here are some very important asphalt patching specifications.
