So, what was wrong with this sump pump pit installation in the following photo:. In some areas of the country, roof x145 above eaves are another area that may need extra protection because they are where ice dams tend to develop.

Homes with steel joists may have a sole plate attached to the bottom of the joists, as shown in the photo below. Homes with foundation beams have different anchoring requirements than homes without foundation beams, and the former are discussed first.

Foundation systems that use steel columns instead of piers to support the foundation beams also have blocking is installed on top of the foundation beams above the columns, as shown in Photo So, in the adtm of this home, they found it in the wet sole plate and rim joist woods.

In this post, I want to discuss more about the differences between the two systems. When wood shims are used, they need to be a minimum 4-inch wide hardwood and used in pairs, as shown in the photo. Depending on the manufacturer requirements, extra piers may be needed to support the marriage line at other locations other than above the foundation beams, as shown in the Photo Even though that difference could be considered an advantage of a CHS over a PHS, I think it can also be considered a disadvantage because when changing water, the owner actually is inspecting the PHS and likely keeping it clean.

Cinder blocks

Gaps between the top of piers and blocking along the marriage line need to c1145 shimmed. As with the case shown in Photo 15, to fix this issue, the rebar should be shortened first and at least 2 inches of the rebar welded the beam.

The central humidification control system has to wait until the thermostat calls for heat before it can work.

In some cases, concrete block is sometimes installed on top of a poured concrete foundation. Blocking needs to be at least the width of the foundation beam flange and at least twice as long as it is wide to assure stability. As can be seen in the photo, v145 gap is present between the end of the rebar and the beam flange even though an attempt was made to weld the rebar to the beam.


Shingles installed directly on the roof deck sometimes melt or stick to the deck.

Vertical stacking is where the shingles are installed in eave to peak columns rather than installing them diagonally starting at atm of the corners over and eave. When backdrafting occurs in flues and chimneys, combustion gases, including carbon monoxide, could be pulled into the home.

Top photo Example of a foundation beam installed axtm a pocket on top of a pilaster in a concrete block foundation wall. And since I have a lot of pictures, here is yet another view of the water droplets on surfaces. Yep, two different types of shingles with likely different expansion and contraction properties that are also were likely not even made by the same manufacturer.

Alternatively, those areas through which the leak air is traveling could be too hot or too cold. This duct is not connected to any x145 or any other devices. In the absence of installation instructions, installers should follow local building codes requirements for fastening the beams together. The piers are supposed to be erected on either poured concrete footings or slabs For manufactured and on-frame modular homes zstm have I-beam asmt members that are part of the home structure, the piers are located under and support the I-beams.

Both sides of each rebar end should be welded to the beam. The only way to know whether a backdrafting or draft issue exists is through investigation.

Depending on the manufacturer requirements, extra piers may be needed to support the marriage line at other locations than above the foundation beams, as shown in the photo below. Examples of concrete block piers under the marriage line and mid-point of the foundation beam. Example of pilaster rebar being used also as an anchor for a foundation beam. In previous posts, I discussed how humidification systems work and how effective a central humidification system might be. By the time I got to the home, we were experiencing our usual humid weather our springs and summers bring.

The two halves are screwed together when the homes are mated together. Example of one style of manufactured home that uses perimeter anchoring to a sole plate instead of foundation beams. The degree of shingle expansion and contraction with change in temperature further varies with thickness, material composition, manufacturing method, lot and a number of other factors.

Technically, this installation does not meet the overall guidelines stated earlier because the foundation beams have not been anchored to the foundation or the structural beams have not been fastened to the foundation beams.


Some background is needed before getting into the termite business.

The agreement is to clarify the duties and responsibilities of the homeowner and the installer. The photo below shows another variation of rebar anchor that is acceptable, although not as ideal as the previous photo.

Shims are not usually used between the foundation or pilasters and the foundation beams.

If a leak develops in the tar or caulk, the usual wrong solution is to apply more tar or caulk, and the new material commonly fails quicker than the previous material. C Tellurium Copper Alloy C Tellurium Copper Rod and Bar C Tellurium Copper ASTM B Tellurium Copper’s TelCu resistance to hydrogen embrittlement combined with its’ high electrical and thermal conductivity make it the ideal choice for electrical applications requiring extensive machining, corrosion resistance, or for the production of hot forged products.

Below is a picture of the pit. Flashing is supposed to be installed between the wall and the roof to prevent water entering through the gap between the roof deck and wall sheathing. In this photo, the darkened woods of the sole plate and rim joist above the water-saturated concrete block is visible.

Add an abnormal snow load and the roof could collapse, as some folks found out during the winter. Examples of marriage line support blocking and a steel column support under the mid-point of a foundation beam.

Example of a proper welding between a structural beam and foundation beam. Many two-story homes have second-story exterior walls that meet first story roofs.

Example of a foundation beam installed in a pocket on top of a pilaster in a concrete block foundation wall. Additionally, verifying whether the home has been properly anchored is difficult to impossible one the siding has been installed. No effort was made to produce frictionless ends, in order to simulate as closely as possible the actual procedure in practice.

While the installer welded the angles to the structural beams, he did not bolt the angles to the foundation, which made this installation not acceptable.
