Foundation Repair for DIYers: Proceed With Caution

Tue, 31 Jan 2012 16:33:53 -0500

DIYers are an enthusiastic and determined lot. They know how satisfying it is to tackle a repair or home improvement project without calling in a contractor. The benefits of saving money, getting the job done on your schedule and being able to brag about your success are good insurance that DIY activities will continue from one generation to the next.

DIYers have never had it so easy when it comes to finding the tools and materials to complete a wide range of home repair and home improvement projects. Most families live within an easy drive of a local Ace Hardware, Lowes, Home Depot, or other building supply outlet. Home improvement megastores provide access to the same resources the pros use –from specialty fasteners and pneumatic tools to masonry sealers, plumbing supplies and plywood sheathing.

Fixing a cracked foundation is a tempting DIY project

Repairing a cracked concrete slab or foundation wall probably ranks high on the list of home repair projects that would be tempting for a DIYer to take on. After all, the repair location isn’t in a main living area like a bedroom or bath, so your work doesn’t have to disrupt everyday activities. There’s no problem getting the supplies you need to repair cracked masonry. And you won’t have to pay much for patching mortar, perhaps some caulk or sealant, and a trowel for making the application. The job shouldn’t take long either. Fill the crack with mortar, smooth over the application and clean up; you’re done.

Treating the symptom rather than the cause

There’s only one problem that might rear its head when you patch a cracked foundation, but it’s a big one. Patching a cracked concrete slab or foundation wall is certain to be just a temporary fix if you don’t also address what caused the cracks in the first place.

Tiny hairline cracks in masonry that are too small to admit a business card are often the result of concrete or mortar shrinking as it cures. These minute cracks are normal and don’t signify any structural issues. The same can’t be said for larger foundation cracks, however. When larger cracks occur, other forces may be at work, like soil pressure or settling soil that doesn’t provide sufficient support for a concrete footing or slab.

When soil movement or soil pressure causes a foundation to crack, a patch repair to fill the crack is certain to be just a temporary measure. In other words, the crack will recur and probably worsen, since the conditions that caused the damage are still present.

Foundation repair contractors provide permanent engineered solutions

Home Depot and Lowes don’t stock the equipment and repair materials that foundation repair specialists have access to. These specialty contractors can drive steel piers into unstable soil beneath a cracked slab or footing, establishing support points in stable, solid soil at greater depth. Weak or unstable soil can be bypassed, creating solid bearing support that will eliminate further foundation damage.

The purpose of this article isn’t to discourage DIYers from making masonry repairs. Instead, the objective here is to encourage homeowners to get an expert opinion about foundation cracks before deciding to make a DIY repair. Established foundation repair contractors don’t charge anything to inspect foundation damage or explain repair procedures and provide estimates for repair work. Instead of investing time and money in a repair that will just be temporary, it’s smarter to get an expert assessment from a foundation repair contractor.

Foundation Damage Caused By Construction Problems

Fri, 27 Jan 2012 08:43:13 -0500

When foundation damage occurs after a house has been built, it’s common to blame soil conditions for damage such as cracked foundation walls, settled slabs, and foundation walls that buckle or tilt inward. There’s no doubt that soil conditions can cause such damage. However, sometimes mistakes are made during the construction process that weaken foundation footings, slabs and walls, making these elements more prone to soil pressure and soil movement that occurs later on. Here are some of the more common construction-related issues that can cause foundation problems to develop later on in the life of a house.

Wet weather. The contractor digs a big hole for a basement foundation and sets up the forms for poured concrete footings. Then it starts to rain. The soil gets muddy and loose; some actually washes away from under the forms. If the excavation remains wet and soft as the footings are poured, there’s a good chance that footings won’t have adequate support in some areas. So they could easily be more prone to cracking or settling after the weight of the house bears down on them.
Missing rebar. Concrete footings and walls need the extra strength provided by reinforcing steel rods (rebar). Building codes establish minimum standards for steel reinforcement (spacing, size and location of rebar), and an engineered foundation will have even more steel. If the concrete isn’t properly reinforced for some reason, it will crack and shift more easily when soil settlement or pressure occurs.
Voids in poured concrete walls. When concrete is poured into wall forms, it needs to be vibrated using special power equipment. Without adequate vibration, the dense liquid mix won’t flow completely into all areas of the formwork. Any air pockets (voids) that result from incomplete coverage become weak points prone to cracking in the future.
Slabs that cure too quickly. In warm weather, a freshly poured concrete slab floor often has to be misted with water and covered so that it doesn’t dry out too quickly. If the contractor neglects these steps, the slab will be weaker and more likely to crack.
Freezing. Special aerated concrete must be used when pouring concrete in freezing temperatures. If this doesn’t happen, the expansive force of freezing water will cause cracks and weakening as the concrete cures.
Backfilling too soon. The excavation for a foundation wall shouldn’t be backfilled until the first floor has been framed and the concrete is strong enough to withstand the weight of the soil. Backfilling too soon can cause a foundation wall to crack and bow inward.

The good news: Foundation problems can be permanently corrected if you call the right contractor

No matter how or why foundation damage occurs, it can be permanently repaired if you enlist the expertise of a foundation repair specialist. These professionals have the training, tools, materials and engineering support to handle all kinds of foundation damage. Your problem will not be too abstract for them, as they have most likely seen it many limes before.

New Crawl Space Insulation Prepares Homes for Winter

Wed, 05 Oct 2011 13:06:10 -0400

Winter will be here before we know it, so it’s time to start winterizing homes to prepare. The best way to get your house ready for colder weather is with insulation. Crawl space insulation keeps the air in your crawl space dry and warm, which will help your entire house as air flows into the bottom of a house and travels up to the top.

Rainy Day Basement Systems is excited to announce one of its newest products: SilverGlo insulation. This crawl space insulation is exclusive to dealerships in the Basement Systems international contractor network of basement and crawl space professionals.

SilverGlo is a graphite-infused EPS (Expanded Polystyrene) Foam Board with a radiant barrier on one side. The use of graphite in the foam increases the R-value by 24% over standard white EPS foam. A 2-inch board of SilverGlo is rated at R-11. This superior R-value will keep any crawl space warmer in the wintertime, as well as cooler in the summer. It will also lower humidity levels in a home.

"If you properly insulate your crawl space—in addition to air sealing and controlling moisture, you will save on energy costs and increase your home's comfort," writes the U.S. Department of Energy.

The Case Against Crawl Space Ventilation in Washington

Thu, 04 Mar 2010 10:37:42 -0500

Open Crawl Space Vents

For far too many years, homeowners have tried to use outside air to dry out their humid basements and crawl spaces.

In many areas of the country, crawl space vents have been written into building codes, and while those are changing, the conventional "wisdom" is that if outside air is allowed to pass through the space, it will keep the space dry.

Rainy Day Basement Systems has the solutions you need for a dry basement in crawl space. if you live in the Oak Harbor, WA area and would like a FREE dry crawl space or basement estimate, call or contact us by e-mail today!

Ask yourself these three questions:

Who is paying to condition to air I'm blowing out of my home?
When it's raining or humid outside, how dry can that air keep my space?
If venting crawl spaces and basements works, why are they still rotting and growing mold?

To put it simply: venting basements and crawl spaces does not work.

Problem 1: Vented Basements and Crawl Spaces Mean Money out the Window

Drafty Crawl Space Door

Except on the most pleasant days, you won't want the air outside your home to be the same temperature as the air inside.

You pay a lot of money to cool your summer air and heat your air in the winter.

If you have a fan in your basement or crawl space that pulls air from that home and sends it outside, then the air that you paid to condition is literally going out the window.

Even if that fan is energy-efficient, this method cannot effectively dry your basement or crawl space enough to make it worth your increased utility bills.

If you have a vented crawl space and do not seal the vents in the winter, then you're inviting cold air into your home. As the cold air enters, it will immediately cool down all warm things in your crawl space, including heating ducts, hot water pipes, water heaters, and furnaces. While these utilities are working harder to maintain their temperature, the cold will rise upwards, cooling your floorboards and creating an uncomfortable, drafty home.

Problem 2: The Air You Vent Your Home with is Not Dry

If it's raining outside, how dry will the air in your basement or crawl space be? Not very, you can count on that.

And during a summer, when warm, humid air is pulled into the basement or crawl space, it's brought into below-grade space. This cools the air, and forces its relative humidity level to rise dramatically. For each degree the air is cooled, its relative humidity will rise approximately 2.2%. Once the air's relative humidity rises past 100%, the excess moisture will be deposited on all cold surfaces in the crawl space. That's not creating a drier home.

Also, letting humid air into your home in the summer will significantly affect your home's cooling efficiency. Air thick with humidity is harder for air conditioning units to cool, as part of the cooling system's job is to dehumidify the air. That's why air conditioners drip. More humidity means more work for the system, and more money for you to spend.

Problem 3: Venting Crawl Spaces Leads to Rot, Mold and Structural Issues

Crawl Space Walls Stained with Years of Flooding and Moisture

If crawl space vents worked, wouldn't the crawl space be dry?

Crawl space rot is a serious problem, and its repercussions can affect the entire home. Crawl spaces with rotting beams and wood will begin to sag, leading to dipping, uneven floors upstairs. Installing crawl space jacks will temporarily aid in supporting and reinforcing the structure, but sooner or later, the rot must be stopped to maintain structural integrity in the home.

Additionally, because air moves upward in the home as it warms, leaving out the attic and upper levels, some of the air in your home is pulled up through the basement and crawl space. If there are mold spores and dust mite waste in these spaces -- even when it's growing behind your drywall -- it will enter the air in your home.

Crawl space vents are also openings in your home that are very close to the ground. This leaves an open invitation for a wide variety of pests to come in and feast on your rotting wood, including termites, carpenter ants, and mice. Other creatures, such as snakes, spiders, and beetles, will also find this to be a comfortable home.

How to Properly Dry a Basement and Crawl Space

Basement With Vapor Barrier on Walls and Floor and Airtight Windows

An Encapsulated Crawl Space with Sealed Vents

Refer to the trinity of healthy below-grade spaces: Vapor Barriers, Dehumidification, and Inorganic Materials.

First, seal off all vents and close all windows. Then, install a plastic vapor barrier on the walls and floors in the basement or crawl space to keep moisture from passing through the concrete and entering into the space. Once the space is sealed, dehumidify the area to pull any remaining moisture from the space and to keep the area dry. If you're finishing the basement, follow up by using as many inorganic, waterproof materials as possible.

Additionally, vinyl basement windows are important, as they can keep drafts and leaking water from the space. And if you want to install an extra bonus, covered basement window wells can keep cold air away from the glass basement windows while also reflecting in valuable natural sunlight to cheer up the space.

A dry basement and/or crawl space means a healthier, more comfortable home. You'll save money on your home in energy-efficiency, and your home will be protected from structural damage due to mold and rot.

Does Humid Air Go Up or Down in My Washington Home?

Thu, 04 Mar 2010 09:17:10 -0500

If humid air sinks, where do clouds and rain come from?

There are two classic arguments used to explain where humid air goes in a home in Bellingham, WA and the Northern Washington area.

Argument 1: Wet air is heavier than dry air. Ventilate and dehumidify the basement to solve this.

The idea here is that as air becomes humid in a home, it becomes heavier, causing it to sink down into the basement and lower levels of the home. Therefore, it will ventilate the basement with outside air to circulate this humid air out of the home and keep the basement dry.

Problem 1: Humid air is less dense than dry air.

Dense things sink and less dense things rise, right? Well, according to Isaac Newton, in his book Opticks, (and USA Today) humid air is actually LESS dense than dry air.

It makes sense. If humid air didn't rise, why would rain fall from the sky when the temperature drops?

So, in a home, humid air rises upward, not downward.

If humid air sinks, will this groundlevel vent keep the basement dry?

Problem 2: If humid air WAS denser than dry air, basement vents still wouldn't work.

Let's pretend for a minute that dry air IS lighter than wet air. Where are the vents going to be in the basement and crawl space? At ground level, right? If humid air did sink, wouldn't it flow downward into the basement through the vents?

Problem 3: Outside air isn't always dry.

If it's raining, humid, or damp outside, how dry will ventilated outside air make your basement? Not very, right? And what happens to your utility bills if you're venting cold air into the home in the winter, or hot air in the summer? You can count on some heavy utility bills.

We seal this air out of our home because we don't want it in the house.

Argument 2: Sealing off the outside air and dehumidifying the space will keep it dry.

Other basement contractors will seal off the area from outside air as much as possible. Once the space has been isolated from the outside, they will install a dehumidifier to remove any extra humidity and to maintain the proper humidity level in the future.

To seal off the space, all vents in basements and crawl spaces must be sealed. Crawl space doors and entrances should create an airtight seal when closed to keep out outside air.

Moisture can also pass continually through the porous concrete, mortar, or dirt, entering a basement or crawl space straight through the walls and floors.

Along with the moisture, water brings a white, powdery mineral salt called efflorescence. If you seal the walls with a paint, this salt will build up behind the seal, causing it to blister and peel.

Instead, mechanically fasten a sheet of plastic- at least 25 mil in thickness- to the walls. This will keep moisture out of the space, helping you fight mold and moisture damage in the home.

A dehumidifier is a great idea as well. Be sure to pick one that is self-draining, powerful enough for the entire space, and is Energy Star rated to keep your utility bills low while protecting your investment.

Dry Below-Grade Spaces

Halloween Special: Creepy Crawl Space Stories

Wed, 15 Oct 2008 12:20:59 -0400

It is amazing the amount of blogs posts you find over the internet, about creepy things people find in their crawl spaces. They are usually accompanied by the most disturbing images.

Crawl spaces are, for the most part, a place no one checks unless it is really necessary, and the necessity usually presents itself in the form of pest infestation, foul smelling decomposing carcasses, mold problems and rotten debris, structures and insulation

However, way before those problems become detectable, they are already contributing to deteriorate your home, your health and your bank account. Filthy vented crawl spaces and a health hazard, and a big hole in your budget, due to the energy loss they cause, especially if you run ducts through them.

On the other hand, a clean, healthy, conditioned crawl space, can save you big bucks on cooling and heating, and provide some extra storage space.

When you compute all the benefits of having your crawl space encapsulated, you will realize that there is no reason to let your home become the set for yet another crawl space horror story.

Keeping the basement dry is important to your home's health

Tue, 10 Jun 2008 10:54:36 -0400

Herald Writer
(Read this article on the Herald site...)

Many people are horrified when they see what the underbelly of their homes looks like, said Dan Malsch.

It's his job to wedge himself into dank crawlspaces and musty basements so he can find a solution to the mold, standing water and musty smells lurking in those places. He brings a camera so he can document the leaking water, mold, rat carcasses and shredded, hanging insulation for his customers.

"People are in shock," said Malsch, who owns Arlington-based Rainy Day Basement Systems with wife Lovisa Malsch.

Malsch spends lots of time educating customers.

"It's a mystery to people why their basements are wet and it's not that complicated," Malsch said.

Conventional wisdom in the construction business is the way to solve moisture issues is to add more vents to the crawl space and basement. Malsch said research has shown that's not true, that vents contribute to the problem by allowing cold air and moisture into the house that gets sucked upward into the home.

The solution is sealing off the basement or crawlspace, he said. The living environment should be separate from the damp earth and concrete under the house. The company uses a special heavy, seven-layer membrane tough enough to crawl on. Malsch compared it to a pool liner The membrane is caulked, sealed and fastened to the walls so moisture can't get through.

The company custom designs a solution based on the needs of the home and the customers wants, Malsch said. Sometimes that means digging trenches, installing a sump pump to keep water out or adding a dehumidifier to filter out mold spores, odors and particulates the air.

Up to 40 percent the air in the average rambler that people are breathing comes from a vented dirt crawlspace under the house, Malsch said. Many of his customers have allergies or health problems. Sealing off the basement or crawlspace and adding dehumidifier improves air quality and reduces humidity in the home, he said.

The company also will prepare basements to be finished. If sheet rock is installed directly on concrete, it will whick moisture and that causes mold to form on the sheet rock. The company installs a vapor barrier inbetween to prevent that problem.

The company doesn't remove mold and Malsch said he isn't certified in pest control. The company's services remove the conditions in the crawlspace or basement that can lead to those problems.

Malsch's business is the regional dealer for Basement Systems Inc., A Seymour, Conn., company with hundreds of independent contractors across the country. Big names in the construction business like Bob Villa of This Old House have touted the company's products on television, and that exposure has led many local customers to his Web site, Malsch said. He serves a territory that stretches from Highway 2 north.

The cost of his services varies depending on the size of the job and the extent of the problems. Sealing off a relatively dry crawl space on a smaller home might cost $4,000. The most expensive job to date was a large home that had duct work flooded with 18,000 gallons of water. That job cost $40,000 to pump out the water and correct the problem that was causing it. But at the completion of the job, Malsch said the homeowners were some of his happiest customers.

"It's a nasty dirty job," he said. "But we're making a big difference for people."
