Flashing at the Base & Weep Holes 

Video still teaching these many years later. Thank you!

The host is fantastic. "...much like grandmother's clothesline..."

These videos have made me fall in love with bricks.

I thank you so very much. I’ve had a leak mystery for 4 years, even had a mason look at it twice, he never saw this. Again, thank you very much for sharing this outstanding video.

So how to resolve a small problem. During a renovation the plastic under the first row of brick damage and removed at the same time as the rotting wood structure. My dilemma now is what is/ are my possible solution/s to resolve this problem.

Thanks, mate. It helps me a lot.

I have never seen flashing or weep holes in residential brick homes in my area.

The last comment is correct that aluminum flashing is not appropriate. BIA’s "Technical Note 7A: Water Penetration Resistance - Materials" can be referenced for recommendations and additional information at www.gobrick.com/Portals/25/docs/Technical%20Notes/TN7A.pdf. In short, you will see references to avoiding aluminum in these sections: SUMMARY OF RECOMMENDATIONS (page 1) Flashing: • Select flashing that is waterproof, durable, UV resistant and compatible with adjacent materials • Flashing materials should conform to applicable ASTM specifications • Do not use aluminum, sheet lead, polyethylene sheeting or asphalt-saturated felt, building paper or house wraps • Use a metal drip edge to extend flashings that degrade when exposed to UV light FLASHING, Sheet Metals, Aluminum (page 6) Aluminum. Aluminum should not be used as a flashing material in brick masonry. The caustic alkalies in fresh, unhardened mortar will attack aluminum. Although dry, seasoned mortar will not affect aluminum, corrosion can continue if the adjacent mortar becomes wet.

You mentioned that the flashing should be at or just below the base plate but you actually installed it above the base plate but said you were installing it below just for the demonstration. Please clarify.

Aluminum flashing isn't appropriate for new masonry. Alkalis in the mortar will cause it to corrode. Other metals such as stainless steel or copper are common and will provide the additional durability.

Back in the 1980s no flashing or weep holes in residential. NONE. .. It's fair to assume probably not before then either. .. Except one time (I guess a home buyer requested it), the boss told me to go dig out a few head joints, he called them "weep holes", that was first time I heard that term.😂 The builder though was Highly Reputable, and we masons never had any complaints. In fact nothing but compliments from home buyers.😌

wall ties near base on framing will keep brick on flashing in place

really impressive and thanks for the video

This man is so fucking wholesome

Tanks for the video .......

Can you use metal like aluminum? That rubber would last what like 50 years maybe? I see metal flashing lasting much longer

Good video... now the question is how to FIX the incorrect install that the builders did on my house.. hmm...

really impressive, thanks very much

Im doing bsmt window sill stones, on a multi level home, they sit on the poured foundation wall, originally there was a thin plastic mortared btwn the wall and stone. My local building supply sold me 20mil poly and told me to use pitch btwn the wall and poly, then mortar the sill to the poly, but there is a bond break because the pitch doesn't harden and the sill wants to rotate out of place. Should I just use mortar on the poly to foundation and pitch on the poly to sill plate? Thank you for your reply

Would you still use a base flashing if your base was an angle iron mounted to the foundation? I noticed no base flashing when you simulated crossing the garage door angle in another video.

Hi, how you doing? What about weep screed? it can be use at the same time with vinyl flashing? or is different? thanks

What if your house does not have weep holes? Could you go around the house and drill through and create a weep hole at the exact depth of the brick in order to prevent going through the WRB? Or do you feel this would create issues? For what it is worth, I can see black plastic sticking out beyond the lowest row of brick (between the brick and foundation).

Self-adhered elastomeric base flashing is THE way to go.

2:20-ish into this video. Flashing, in the late 90's was recommended to go through - as in this video. This was stopped in Michigan, as it allowed for water to seep in between the joint, freeze, expand, and crack the brick. Also, we do not push the flashing back. We cut it, keeping a square edge against the back lower corner, allowing for proper water run off. However, it is appearant that this has happened on jobs. Laying mortar on the flashing is not a good idea. this allows for issues with the wall rolling. Open head joint is not good Hornets, or bees, or other insects build nests. water builds up, freezes and expands. Also, how is one going to prevent mortar from filling the head joint, if the mason fails to clean out the head joint properly? Also, I see no mortar net between the brick wall and the plywood wall. This leads to a failed weep system, due to piled up mortar at the bottom of the wall. Also, ropes are bad weeps in Michigan, they soak up water in the winter, freeze, expand, and crack the wall.

ever seen the ground after a mason has laid brick,, mortar,, what is gonna keep mortar from falling behind wall. commercial jobs they use a mortar break on residential you don't have enough room between brick and wall to use a mortar break if a builder is smart he'll pay his bricklayer a little extra to put some small gravel about 3 inches tall from weep holes

Excellent video! Really informative. I just had my house built and the builder has put weeepholes but I did not see any flashing during construction. I pulled out a weephole cover to check and sure enough all I see is mortar at the back no flashing! Why has my bricklayer missed this! Disaster. Any suggestions as to what we should do?!

What do you do with the black flashing hanging over the brick? Can you cut it off?

What happens if you forgot the flashing part!?

who would want to look at the flashing as it was shown through the wall in the middle of the wall?

How does the water get behind the wall if the house is built right

blue skin works to

Really interesting video. Enjoyed it and learnt a lot. I was hoping you were going to talk about combining weep holes and expansion joints! Now that would be really useful. Killing two birds with a stone. Thanks a lot. Howard

👍👍👍

6:07 it was all going so well........lol Very informative and worthwhile video, shit jokes aside.

FIRST STEP would be to put a seam sealer on the wall to the slab. this house got fucked from the start lol

That is why the trade is dying. Does wind treat a commercial building different from a residence? Does an earthquake? Stupid code.

A weep hole is where water comes in when it floods. It let's bugs in as well. I've never seen any water coming out of my wall. But I've seen it going in. It must be a conspiracy to make sure houses flood and bugs get in. This ensures plenty of jobs in the related fields and services. Just like getting new eyeglasses every year ensures steady income for the eye doctor. Your eyes are getting worse every year because they increase your prescription every year. Then when you're so blind glasses don't work. Then they can do surgery. It's a sceme just like some shampoo. Some shampoo companies profit from hair loss. Hmmm...

ALUMINUM!! The way to go for brick flashing

zzzzzzzz
