Q: What are the concerns with Colorado soils? Are there some areas of town that have bad soil?

Tuesday, July 28th, 2009

A: This question brings up a complex issue, but the answer is fairly simple. Soils in Colorado can indeed be very tricky. Colorado Springs’ terrain is technically classified as a “high desert,” but if you drive west for five minutes, you’re on a 14,000 foot mountain, and if you drive east for a few minutes, you’ve in agricultural prairie land. We have the gamut of soil types, which means a big difference in compaction, drainage, etc.

Having a soils test performed is the single most important step in building a home. If this isn’t taken care of, every other aspect of the job will suffer. Stauffer & Sons’ team is a group of experts in the Colorado building market. We’ve been building for ten years—we know the land and topography very well. Consulting with us before building can save a lot of time and headache with regard to expansive soils.

Though it may not seem obvious, having a soils test performed on-site at an existing house is also a very good idea. There are some neighborhoods and developments in town that have a history of being problematic, and it can empower potential homebuyers when finding out how the soil under their prospective home is going to act ten to fifty years down the road. Bad soil under an existing home can be a ticking time-bomb, even if there are no signs or symptoms yet. Having a soils test performed is like taking an x-ray of the property, to see what’s under the pretty outside.

A home that has been built on top of bad soil can be a nightmare: heaving of the structure or foundation, leaky basement walls and crawl spaces, and settling of foundation walls can all be caused by insufficient knowledge of the soil a home is built on.

Having said all this, Stauffer & Sons Construction has spent many years repairing structural issues in homes, and our team can fix a home that’s been built on problematic soils, even if damage has already occured. We can anchor a home to prevent any damage in the future, which sometimes can mean the difference between being able to sell a home and not being able to.

Q: How do wells and septic systems work? Do they need to be maintained?

Tuesday, July 28th, 2009

A: Wells and septic systems are installed within the same time frame: before framing or foundation work begins. (What we call “site-prep”). Here’s a little info about each of them:

Wells:

Wells today are essentially the same as they’ve been for thousands of years. In old movies, you’d see a little girl with a small bucket in her hand, skipping down to the family well to fetch water. Today is basically the same, only today we use pumps, drill bits and pipes. To begin, a hole several inches wide is drilled into the ground (usually several hundred feet) by a well driller who uses a large truck with a very long diamond-impregnated drill bit. This process can take hours, or even days, depending on the soil composition. Once the hole has been drilled, a pump is installed at the very bottom of the well which is connected to a pressure tank at the surface, which creates negative pressure to suck water out of the ground and push it into the home.

After this process, the County Health Department will test the water for simple potability (drinkability). If a more detailed analysis of the water is desired, a water sample is then taken to an environmental health laboratory. A cheap, quick way to test your water is to look in your dishwasher: is your water discoloring your plastic dishes? If so, you may have heavy minerals. Once a well is installed, there is no regular maintenance necessary. Occasionally, a well pump will need to be replaced, but they’re built to last for decades.

Septic Systems:

Waste water from toilets (called “black water”) and runoff from showers, washing machines, sinks and dishwashers (called “grey water”) is collected and drained downhill into a two-chambered tank (called a “septic tank”). The first chamber catches and holds solid waste, while the liquid waste will spill over a specially designed wall (called a “baffle”), and into the second chamber, then out of the tank into a leach field. A leach field is a network of perforated pipes buried in gravel. This disseminates all liquid waste into the ground, responsibly, legally and hygienically.

Septic systems require more maintenance and care than wells. They also cannot be abused like sewer systems can. Unlike living in a city with a sewer system where you can flush anything and everything down the toilet or use a garbage disposal to discard items never meant for a sink in the first place, septic systems need special attention. Fats and oils, as well as bones and other solid matter should never be disposed of in a septic tank. Garbage disposals are also not recommended for septic systems as they will clog up the lines faster than anything.

All septic tanks should be pumped every few year or so, depending on how many people are living in the home. Septic tanks can also be probed with a scope to visually inspect for damage. Occasionally, complications arise, particularly with leach fields. We’ve had some clients with older homes with a leach field that had become completely saturated. In this situation, a new (secondary) leach field must be dug, or disastrous results can follow: a flooded basement, toilets backing up, etc.

When Stauffer & Sons Construction builds a home, we like to set the septic tank lower than the slab (bottom of the basement) whenever possible. This avoids needing a special pump to force waste uphill—which is problematic and not recommended.

Q: What considerations should be taken when buying land to build a home on?

Tuesday, July 28th, 2009

A: The answer to this can be exceptionally complicated. Only a competent land realtor can truly answer this question with any authority. Stauffer & Sons Construction has worked with land realtors in the past and is happy to make recommendations based on a client’s needs.

The short answer is that there are several tests that need to be run and questions that need to be answered before actually purchasing a home. Zoning, site location, surveying, government easements, setbacks, utilities, title history, soil percolation tests, storm drainage, and covenants are just a few of the issues involved when purchasing a lot to build a home.

Our recommendation is this: if you’re considering building a home and would like to build with us, don’t wait until you’ve purchased the land to contact us. We can best serve you if you contact us before choosing a lot. This allows us to give you a fair analysis of the property, and discuss the challenges in building, if any.

In the past, we’ve received phone calls from clients who had just purchased land with the intention of building, but after visiting the site, we had to share the bad news that the lot was completely useless for building a home on. This is a heartbreaking experience, yet is entirely avoidable. By visiting a site before the transaction is completed, we can help prevent this from happening in the future.
