Background description of company and its products:
	Clarke and Denham, LLC, designs and manufactures Culvert Topstone, a precast concrete headwall for residential driveway culvert pipes. We currently sell to Brown County Rental in Aberdeen, OH and Core & Main in Batavia, OH and Lexington, KY.
Recommended Uses-Primary: Culverts and Drainage Structures
Recommended Uses-Alternate: Please Select ...
Outstanding Features or Advantages Claimed:
	1. Inexpensive way to improve aesthetics of driveway entrances and help make right-of-way property owners happy. 2. No heavy equipment needed. Light enough to be carried by one or two people (each wall weighs approximately 130 lbs). 3. Easy and quick installation. Only top and sides of pipe need to be exposed. Wall is then placed on top of pipe end. A built in clamping mechanism attaches wall to pipe, activated by turning a couple of bolt heads, one one each side of wall. 4. One size wall fits a range of pipe sizes. Current design fits pipes with outside diameter 13-17". Later designs will probably fit 10-14" and 16-20". Other sizes could be made. A lip on front surface of wall hides gap between pipe and inner sides of wall. Will attach to any pipe material, whether steel, concrete, or plastic. Clamping mechanism works best with steel and concrete pipes, but will also work with plastic. 5. Wall is light enough so pipe itself supports the wall. No need for substrate or foundation. 6. Protects otherwise untreated pipe end from smash damage by trucks, tractors and other vehicles. By preventing smash damage, the original pipe diameter called for by runoff and drainage requirements is maintained. Also, unsightly pipe damage is prevented. 7. If struck by a moving vehicle, the wall would likely dislodge, rather than present a potentially dangerous fixed object as would be expected with a heavier, industrial size headwall. (I have seen at least one instance of this. A snow plough knocked a wall off a pipe. The plough was undamaged and apparently just kept going. The wall was knocked off the pipe and displaced several feet. Only a small chunk of concrete on the wall was damaged. The pipe was completely intact. The same wall was later reattached to the same pipe.) 8. Wall is not designed for or capable of retaining a large amount of backfill. But the wall does hold some backfill, enough for landscaping rocks or to grow grass over the pipe. Makes a nice alternative to an untreated, exposed pipe end.
