Potential entry routes for radon in homes with poured concrete foundations include cracks, areas with exposed soil or rocks, openings for utility fixtures or hollow objects such as support posts (see figure 1).
Soil gas containing radon can enter a house any place it finds an opening where the house is in contact with the soil. In this image potential entry routes for radon in homes with poured concrete foundations are shown. The radon entry routes described in the image include; exposed soil or rock in crawlspaces, cracks or flaws in foundation walls, around utility penetrations and support posts, hollow objects such as support posts, cracks or flaws in floor slab, floor drains and sumps and floor/wall joints.
Soil gas containing radon can enter a house any place it finds an opening where the house is in contact with the ground. In this image potential entry routes for radon in homes with concrete block wall foundations are shown. The radon entry routes shown in this image include; unclosed voids at the top of exterior walls, unclosed voids at the top of interior block walls which penetrate the floor slab, missing mortar between blocks, cracks through the blocks or along mortar joints, floor/wall joints, and pores in the face of blocks.
A certified radon professional will likely perform one or more diagnostic tests to help determine the best radon-reduction system for your home. For example, your contractor may use chemical smoke to see the air flow sources and radon entry points by watching a small amount of smoke that has been placed into holes, drains, sumps or along cracks. Another type of diagnostic test is a Pressure Field Extension Test (or communication test). This test uses a vacuum cleaner (e.g., a Shopvac) to measure how easily air can move from one point to another under the foundation and estimate the number of suction points and fan size needed for an active radon-reduction system.
The joint between the foundation wall and basement floor can be a major entry point and contributor to the radon level in a home. Sealing the joint between the foundation wall and foundation floor can help reduce radon entry. This image describes how this joint can be sealed. First a hammer and chisel are used to enlarge the crack between the foundation wall and foundation floor joint. Next a Ethafoam backing rod is used to create a more durable seal followed by filling the crack with polyurethane caulking. Before sealing, it is important to ensure that proper surface preparation is done by following the caulking manufacturing instructions to ensure a good seal.
After closing major openings, a further reduction in radon levels can sometimes be achieved by sealing minor entry routes that are visible or accessible. Minor cracks in foundation walls and floors can be sealed. Larger cracks require special techniques; consult your building material supplier or a contractor. The gap around utility penetrations (e.g., water, sewer, electrical, natural gas, fuel oil) in walls and floors can also be sealed.
Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction and can help increase their effectiveness. Proper preparation of the surface area to be sealed is extremely important to create an effective and long lasting seal.
The cost of sealing entry routes is highly variable. It can range from a few hundred dollars to $2,000 or more. Although the material cost is relatively low, it is very labour-intensive to do a comprehensive job. As the house ages and settles, the seals can deteriorate, and new cracks or entry routes can appear. As a result, there will be an ongoing cost to maintain the seals.
One major necessity of owning a windshield repair business -- or any long crack resin business, for that matter -- is efficiency and ethics. If your business can't operate with efficiency and ethics, you'll potentially lose out on significant profits.
In the windshield crack repair and auto glass industry, owners often lose out on opportunities because of a misconception propagated by windshield manufacturers and large auto glass companies such as Safelite: the notion that windshields with cracks longer than six inches cannot be repaired and require a full replacement is not true. In the Ultra Bond v Safelite Lawsuit, Safelite did not produce one word of evidence to show the validity of this six-inch, size of a dollar bill false and misleading advertising. In fact evidence was uncovered that Safelite/Belron testing showed, \"up to 24 inches was safe and viable\". Evidence was also uncovered that Safelite knew and admitted that it was safer than replacing the windshield.
The reality is, windshield repair technology has come a long way in preventing the need for unnecessary replacements. Here's a quick guide to help you determine whether a vehicle is suitable for a long windshield crack repair.
There are two major considerations to determine whether a windshield needs a full replacement or can be repaired using a long windshield crack repair kit. These two factors in order of dominance are length and dust/dirt in the crack and there is correlation between the length and dust in the crack. Cracks at 14-inches and under will have dust in the crack less than 3% of the time. The ROLAGS recommendation is 14-inches.
When a stone hits a windshield it will make one of two types of damage - an edge crack or a stone-break/chip. There are two types of cracks, an edge crack and a floater crack. Over 90% of cracks will be an edge crack. This is due to manufacturing defects around the entire perimeter edge area which causes this area to fracture easier than the rest of the windshield and cracks immediately to about 8-10 inches. The other crack is a floater crack. This is a stone-break or chip that cracked-out, most often due to severe temperature change. The floater crack is not nearly as common as the edge crack, usually 10% or less. This is because over 90% of stone-breaks or chips will never crack-out in the most populous areas of the United States due to the fact that most people choose not to the live in severe temperature states.
Smaller, shorter cracks 3-6 inches can be repaired by some auto glass repair shops, however many specializing in auto glass replacements such as Safelite say they can but usually bait and switch the customer into a replacement when their technician shows up. If an auto glass repairer can correctly repair a short edge crack then they can repair a long edge crack. It is just a matter of sliding the proper windshield crack repair tool with the proper crack repair resin a few more inches. Repairing a long crack correctly on your windshield requires specific tools and experience with specific long crack resins. Typically, though it is by far much easier than a replacement and it can be easily done on cracks up to 18 inches long with the right tools and resins. The standard in the United States is 14 inches long.

The type of stone-break is also a main factor in determining whether a repair or replacement is necessary. There are five basic types of windshield stone breaks: combination break, half moon, bullseye, radiating crack, and star breaks. Some say that star breaks, bullseyes, half moon, cracks, and other chips and cracks that can be covered with a quarter can be repaired, however the standard in the United States states the specific sizes with each type chip- see the Repair of Laminated Auto Glass Standard. Keep in mind that multiple cracks or chips off the same impact in a vehicle's windshield may also call for more advanced treatment.
The location of the windshield's damage is also a factor when determining if a repair is possible. If it's in the driver's line of sight, it could cause complications. For safety reasons, auto glass technicians must make a careful judgement as to whether the damage could potentially impede the driver's vision. If the crack or chip could feasibly interfere with the driver's line of sight, then a replacement may be the safer option. See the United States Windshield Repair Guidelines and the Repair of Laminated Auto Glass Standard for when the damage is in the acute or driver's primary viewing area. 153554b96e
