Soil Testing When test/water damage

When should you call un a soils engineer ?

Many builders and architects are reluctant to hire engineers perform subsurface investigations, and that’s easy to understand : The cost of a house can go up few thousand dollars . Despite the cost, there are circumstances which consulting soil engineer is a wise investment.

If you wondering how earth you are supposed to build a house on a lot with a steep slope, then you need an engineer to determine the soil properties and to evaluate the stability of the incline.

A local history of the presence of the clay soils that are susceptible to shrinking and swelling with changes in moisture content also requires careful investigation and usually , specialized deign services and the use of an out of the ordinary foundation.

Consult your experience . If you are crossing your fingers and hoping the soil conditions would not cause a problem ,you are probably , right to be uneasy . Call in the specialist

Just like concrete in you basement slab. Failure to compact is what leads to cracking sidewalk uneven slabs.

It is particular important that fill be placed in thin layers so that the densification effect of the compaction equipment is it felt the all the way to the bottom each layer. The maximum thickness for each layer depends on soil type : Ordinarily about 12 inches for sandNS 6 inch to 8 inch for clay. The required degree denisification usually set forth by the local building code and specified as some percentage of maximum dry density as determined by one of several standard methods.

The moisture content of the fill material must also be controlled . If the moisture is too low , it is difficult for individual soil grains to realign themselves into the densest configuration ; adding moisture lubricates the grins and make realignment easier . But if there is too much moisture , the soil becomes unstable under the influence of compaction effort will be the water between the soil grins and result in a water bed like rolling the soil . Granular soils such as sand are most desirable for use as fill because their moisture content can be easily tweaked.

TO prevent settlement problems, soil that is stable and compacted must extend at least half the distance from the base of the footing to the influence depth ( the farthest distance beneath the footing that its weight is felt by soil particles.) Strip foundations ( such as the wall in the drawing below right ) as the pedestal the drawing and thus have greater influence depths.

Stable compacted fill extends half the influence depth. Only soil grains inside this stress bulb feel the weight of the foundation. The formula applied when the length of the foundation is 10 or more times greater than its width.

Stable compacted fill extends half the influence depth , Influence depth is (ID)=4xB

Details for drying Foundation

As a research architect at the Building Research Council of the University of Illinois, I am paid to solve some of the more nagging problems that houses have . Frequently , I visit troubled houses, troubled houses, and the most common problem I encounter is poor drainage away from the foundation .This problem became worse as wetlands were developed ; I know what to expect when the name of the developed : I know what to expect when the name of the development is Frog Hollow .

I was once asked yo looked at a house that had settling problems . An addition , built over a crawl space was moving down the relative to the main house. the dirt floor of the crawl space was even with the bottom of the footing. The soil along the of the footing . The soil along the edge along the edge of the footing was in small clumps, unlike the grainy fruity surface of the rest of the floor . I dug away a little more and found drain and found save that reminded me of a prison escape tunnel . In all, 10 ft. of the footing was under minded.

I call my studies of the zone where the house meets the ground building periodontics. Proper preventative care of this area can avoid a variety of problems, some less obvious and a lot more serious than a damp cellar.

For example , a common problem in basements particular those with block walls, is inward buckling . This usually shows up as a horizontal crack one or two blocks below grade , or at window walls , stepping up or down at the corners . A study I did with Illinois State Geological Survey revealed the cause . Clay soils shrink during spells forming a crevice between the soil and the foundation wall. Wind and light rains carry dirt into this crevice . Then, when seasonal rains come, the soils swells back to original dimension, plus the increment of added soil . Over time , the walls watched inward and eventually buckles. You avoid this problem by keeping the soil next to the foundation dry.

Slabs suffer from water problems , too. Garage floors, for example , commonly crack at the outside corners near where gutters drain. This cracking may be due to upward expansion of water directly below the corner. It can also be due to adhesion lifting of the perimeter wall, a situation occurring when saturated soil freezes fast to the foundation wall . The soil nearest the surface is the first freeze , and as the cold water continues , deeper soil freezes. This saturated soil by 8 percent as it freezes, exerting a tremendous force that lifts the soil frozen to the wall above. The wall lifts and cracks the slab .

Moisture damage around the foundations is not limited to masonry problems . In 1947 , Ralph Briton , the government researcher whose work led to current attic ventilation standards , showed that water vapor traveling upward from damp foundations caused moist attic moisture problems . He colluded that if attics are isolated from wet foundations, the standard 1:300 venting ratio could be reduced to 1:3000 .

Stucco R value important mildew prevention

Prized for its weather resistance , durability , and timeless beauty , stucco has longbow one of the most popular exterior wall finishes . As a building material , stucco is essentially and exterior plastered of Portland cement, sand , and water . Other ingredients may include lime , masonry cement , and various special additives for enhancing properties like crack resistance , workability and strength . With a few exceptions , stucco is applied much as it has been for centuries a wet mix is troweled onto the wall in successive layers , with the final coat proving the finished color andy decorative surface texture desired .

The two traditional stucco systems are the three coat system for standard wood framed wall and the two coat system used for masonry walls , like brick poured concrete , and concrete block. And today , there’s a third process the one and coat system which allows you to finish standard framed walls with a single layer of stucco , saving you money and considerable time and labor over traditional three coat applications. Each of these systems is described in detail not the next page.

The following pages show you an overview of the materials and basic techniques for finished a wall with stucco . While cladding an entire house or addition is a job professionals masons, smaller projects and repair work can be much more doable for the less experienced . Fortunately , all the stucco materials you can be sure of getting the right blend of ingredients for each application . During your planning, consult with the local building department , fire ratings for walls , control joints, and other critical factors.

Stucco is one of the most durable and low maintenance wall finishes available but it requires getting watch stage of the stucco itself. For this reason , Dyers may want to limit their stucco work to small structures or to repair work only.

Three coat stucco is the traditional application for stud framed walls covered with plywood , oriented strand board OSB, rigid foam insulation sheathing . It starts with two layers of grade D building paper for a moisture barrier. the wall is then covered with self furring expanded metal lath fastened to the framing with galvanized nails .

The first layer of stucco , called the scratch coat , is pressed into the lath , then smoothed to a flat layer about 3/8 inch thick . While still wet , the stucco is scratched with a raking tool to create keys or tooth for the next layer to adhere to .

The brown coat is the layer , Its about 3/8 and brings the wall surface to with 1/4 inch of the finished thickness. Imperfections here can easily telegraph through the thin final coat, so the surface must be smooth and flat. To provide tooth for the final layer ,the brown coat is finished with wood float for a slightly roughed texture.

How to Locate & Evaluate Make Emergency Repairs

If you have an unfinished attic, examine the underside of your roof with a flashlight on a rainy. If you find wetness , discoloration, or other signs of moisture , trace the trail up to where the water is making its entrance .

Water that flows toward a wall can temporarily diverted to minimize damage . Nail small block of wood in the path of the water , and place a bucket underneath catch the drip . On a dry day , drive a nail through the underside of the roof decking to mark the hole.

If the leak us finding its way to a finished ceiling , take steps to minimize damage until the leak can be repaired . As soon as possible, reduce the accumulation of water behind a ceiling by poking a small hole in the wallboard or plaster and draining the water.

Once you mark the source if a leak from inside , measure from that spot a point that will be visible and identifiable from outside the house , such as a chimney , vent pipe , or the peak of the roof . Get up on the roof and use that measurement to locate the leak.

If your roof is severely damaged , the primary goal is to prevent additional damage until permanent repairs are made . Nail a sheet of plywood to the roof to serve as emergency cover to keep out the wind and water . Tip: For temporarily repairs, use doubled-headed nails , which cane easily removed . Fill nail holes with roofing cement when the repair is complete.

Cover the damaged area by nailing strips of lath around the edges of a plastic sheet or tarp.

To reattach a loose shingle , wipe down the felt paper which is the first layer above ply wood.Let each dry, then apply a liberal coat of roofing cement . Press the shingle down to seat it in the bed of cement . Tip: Heat softens the roof’s surface , and cold makes it brittle slightly with hair dryer to make them easier to work with and less likely to crack.

Glue down buckled shingles by cleaning below the buckled area, filling the area with roofing cement , then pressing the shingle into the cement . Patch cracks and splits in shingles with roofing cement.

Check the joints which are common places for the leaks to occur . Seal any gaps by cleaning out and replacing any failed roofing cement.

Areas that typically leak vent stack, ridge which is the top of the roof, drip edge , soffit , and cracks real close up adjacent the roof. Roof damage can tend asphalt 30 years, metal roof 50 years and cedar shake if properly and maintain just like slate roof hundreds years .
Other real important things ice guard shield properly lets the material of the roof contracts makes it last longer time.

Toilet : Clearing Clogs Floods Prevention

The toilet is clogged and has overflowed . Have patience . Now is the time for considered action. A second flush is a tempting but necessary gamble. First, do damaged control. Mop up water or if really look up website for severe damage control
Next, considered the nature of the clog . It is entirely natural or might foreign object be contributing to the congestion? Push a natural block blockage down the drain with a plunger . A foreign object should be removed , if possible, with a closet auger . Pushing anything more durable than toilet paper into the sewer may create a more serious blockage in you r drain and waste system.

If the tub , sink, and toilet all back up at once, the branch drain line that serves all the bathroom fixtures is probably blocked and you best recourse is to calla drain clearing service.

Tools and Materials

Towels. Closet auger, Plunger, Skirt (force cup ). Possibly a snake reach further down.

The trap is the most common catching spot for the toilets clogs , Once the clog forms , clog forms , flushing the toilet cannot generate enough water power to clear the trap, so flush water backs up. Traps on modern 1.6 gallon toilets have been redesigned to larger diameters and are less prone to clogs than the first generation of 1.6 gallons toilets.

Not all plungers were created equal . The standard plunger is simply an inverted rubber cup and is used to plunge sinks, tubs, and showers. The flanged plunger , also called a force cup , is designed to get down into the trap of a toilet and use it as a standard plunger.

Drain Clearers

The hime repair marketplace is filled with gadgets and gimmicks , as well as all established products, are intended to clear drains all types . Some help , some are worthless , some can ever make that problem worse. Nevertheless, if you are the type of homeowner who is enamored with new products and the latest solutions , you may enjoy testing out new drain cleaners ashley become available. In this photo , for example you will see relatively new product that injects blast of compressed CO 2 directly into your toilet , sink , or tub drain to dislodge clogs. It does not cause any chemicals to enter the waste stream , and the manufacturers claim the Co 2 blast is very gentle and won’t damage pipes . As with any new product, use it with caution . But if a plunger or a snake is not working , it could save you the cost of a plumber’s house call.

Importantly to have water damage specialist to check out the damaged the backer board has passed through it cause damaged. If it has need dehumidifiers to dry out the drywall cavity so no water damage turns into mold.
