Mold / Mildew Build up
surface water or migration
In Colder CLimates, the frozen water expands, which will cause the size of cracks to stretch and even break. Mold appears when water remaines for periods of time ? Mold is a fungus that grows in damp places. There are many types of mold. In nature, its job is to help with the decomposition of organic matter. Mold becomes a problem when it grows inside a home. Damp basements and crawl spaces are ideal breeding grounds for mold, but any moist or wet area will do. A leaking pipe, a leaky roof, and window condensation can all lead to mold growth. Because mold often grows beneath floors and behind walls, a home can be infested with large mold colonies without being seen.

WATER MANAGEMENT SYSTEMS
The WalDry updated Drainage System takes care of surface water and the water that enters through cracks in your foundation wall. Structural Assessments are prepared including the following:A) An inspection trench is dug against the outside wall anywhere the foundation meets dirt.- Any cracks identified are sealed to prevent water from entering into the foundation.The system is installed to remove any surface water away from the foundation walls.This would include our WALDRY (WPRS) Pressure Relief System — inside drainage system:
The WALDRY (WPRS) Pressure Relief System handles hydrostatic pressure that exist undergtound and creates hydrostatic pressure on to your basement walls and upunder the cement floor, which often causes water to seep through cracks along the walls and in the floor, as well as where they meet one another, often occuring in many wall and foundation systems, including floor cracks and at the seam where the floor and wall meet leading to discoloration and moisture and mold build up along lower block walls. The WALDRY (WPRS) Pressure Relief System consists of :WALDRY PLAN Professional Management and ManpowerPipingA pressure relief pump and pit Diverters, connections, and system components Downspouts are changed and correct positions are established Diverters, discharge and outlets are correctly installed and updated System Promotes: Cracks are sealed Release of water in the walls Client Participation on Seeing a change of condition Homeowers are shown the progress as changes are made.

TYPES OF FOUNDATION CRACKS
Horizontal foundation cracks that are located at mid-wall height on a concrete foundation, block, or stone wall that is bulging inwards at middle height on the wall have probably been caused by vehicle traffic or earth loading. If there’s a driveway near the wall or if the site’s history includes the movement of heavy equipment near the wall, vehicle loading is the likely cause. Backfill damage, such as excessive height or premature backfill before the first-floor framing was in place, is another potential cause of this type of crack. If the home is located on a hillside, earth loading or earth loading exacerbated by water or frost could have caused the cracks. If your home is in an area with wet soil, earth loading or earth loading exacerbated by water or frost could still be the cause.
Next, there are horizontal foundation cracks that are located low on a foundation wall. These are caused because the forces exerted by soils against a foundation wall increase exponentially as you go from the surface level of the soil against the wall to the areas near the bottom of the wall. Essentially, earth pressure is greatest at the bottom of the wall. A wall that has been laterally dislocated at or near its bottom has probably been damaged by earth loading. Horizontal dislocation of a masonry block or brick wall may appear first as a crack and then later as a lateral movement.
DIAGONAL FOUNDATION CRACKSThere are many clues that help diagnose the probable cause of diagonal foundation cracks in buildings. Here are some of the most common.
Some cracks extend from the corner of a wall towards an adjacent opening and are wider at the top than the bottom. Usually, these are caused by foundation settlement, expansive clay soil, frost damage, or damage from a shrub or tree close to the wall.
Some cracks originate under a ground floor window and extend from the sill to ground with the sill bowed up. These cracks are often due to foundation heave, clay soil, frost, shallow or absent footings.
If you live in a colder climate, you may have a crack in a corner of your home. Frost heave, frost lensing, shallow footings, water problems, or insufficient backfill could have caused these.
Vertical or diagonal cracks that open suddenly after rain are serious problems. They can be caused by the settlement of the structure over sinkholes.
Sometimes straight or diagonal cracks appear over windows or doors. They could appear as horizontal along the top or bottom of the header and vertical at the ends of the header. This may be due to differences in thermal expansion between the header materials and the wall materials. These cracks could also be either vertical or diagonal at the center of the header or the corners, which is a loading failure. If the cracks are vertical or diagonal at the corners, this could be a point-load failure.
VERTICAL FOUNDATION CRACKSVertical foundation cracks (shrinkage cracks) are the most common and “least” concerning types of cracks. All cracks are an issue, this type of crack is just the easiest to deal with. They are sometimes v-shaped—wider at the top of the wall and then diminishing or stopping before reaching the bottom of the foundation wall. This is less common. If you have a wall crack that goes all the way into the floor, it may involve the building footings and may be a settlement crack that is damaging the structural integrity of the building.
While it is curing, concrete shrinks. With poured concrete, this shrinkage causes cracks. It’s common for there to be minor shrinkage cracks that are hairline, random, intermittent, and meandering in the concrete. If the concrete was not properly mixed, or if control joints were omitted, the shrinkage cracks will be larger and appear more frequently. Sometimes cracks form because of the omission of or the placement of steel reinforcements (tie-rods).
Most of the time shrinkage cracking is a result of a poor concrete mix, rapid curing process, or other factors with the original construction. It’s less likely that shrinkage cracks will require structural maintenance or repairs because these cracks aren’t expected to continue to change after the initial curing.
We say these cracks are “least” concerning because they are generally NOT structural in nature. They can be, but usually are not. When compared to horizontal and diagonal cracks, which generally ARE structural in nature. Most simply require waterproofing by doing an interior crack injection.
MANAGING EXTERNAL FORCES
WATER MIGRATION DAMAGE
A damp or musty smell If you smell a damp, musty, or earthy odor, you might have a mold problem. That’s because mold secretes a pungent odor, and it’s one of the biggest giveaways that mold is taking hold in your home. Yet, some homeowners are so used to the smell that they aren’t even aware of it. If you are unsure, ask a friend or family member to stop by and sniff for themselves.Black spots or stains. Mold often appears as dark spots or stains on walls and insulation. But there are many types of mold which look very different — from gray or green furry tufts to white streaks to colorful splotches of orange, pink, or purple. (Trust us, it’s not nearly as pretty as it sounds.) Peeling wallpaper or paint If you see bubbling, cracking, or peeling in wallpaper, it means moisture has gotten under the paper and weakened the glue. Mold loves to grow in these damp pockets, hiding just out of sight.Damp, humid basement. Basements are a prime breeding ground for mold. That’s because they are usually colder than other rooms in a home, and cool temperatures create condensation. In addition, cracks in the foundation can allow water to enter and provide a place for mold to grow. Condensation on windows and pipes Mold thrives in areas where condensation creates moisture.Allergies and health problems. Toxins released by mold can cause serious health problems. Symptoms of mold exposure can include red and watery eyes, sneezing, itchiness, chest tightness, and shortness of breath. People with asthma or weak immune systems may be especially susceptible. How to Prevent Mold in Your Home ?It’s much easier to prevent mold than get rid of it once it’s there. Follow these six tips to help reduce the risk of mold in your home.
Eliminate leaks and other sources of moisture. Mold needs moisture to grow. Repair all leaking pipes and plumbing fixtures to help keep mold at bay. A foundation waterproofing professional can help. Use a dehumidifier Run a dehumidifier in the basement or any area of your home that feels damp or musty. Aim to keep humidity levels at less than 50 percent. Ensure proper ventilation Make sure your kitchen and (especially) bathrooms have adequate ventilation. Run bathroom fans while in the bath or shower to help remove moisture from the air. Keep bathrooms clean. Clean sinks, drains, and shower walls regularly. Hang wet towels instead of leaving them on the floor.Change furnace filters regularly. High-efficiency particulate air (HEPA) filters are best for trapping mold spores and preventing their circulation throughout a home. Get help from a pro.
