Re: Best maintenance for rain gutters

big gutter, big problems hehe. Here's one, exposed structural steel in the rain gutter - i need to fix this in a hurry!

The truth is a lot of the problems occurred because of shortcuts made 10 years ago. It's so tempting for workers/contractors to cut corners if they think no one will actually check their work, so I learned to crawl in celings, and over roofs with the workers to see for myself.

Would you believe that big ALULOD had overflow problems? At first i thought it was just the downspouts, but I found the real reason:

Those are 2 3" drains from the neighbor's roof, discharging directly onto my rooft! Shortcut nanaman! No wonder my roof was damaged and my gutters overflowing.

I talked to the neighbors who had no idea it was like that, they were wondering why water kept seeping out their firewall. Turns out that bitin din yung flashing sa side nila, so the rain discharge also seeped into their partition walls. Now they're mad at their contractor as well.

Re: Best maintenance for rain gutters

Bro zepol,

haven't you tried the THOROSEAL products ?, it might just help and solve your seepage problem dyan sa laki mong gutters.

Bro, you amazes me, you really do with your cunning expertise, am so glad kasama ka namin dito sa PHM.

CHEERS and GOOD LUCK sa mga projects mo.

Re: Best maintenance for rain gutters

@rosy
THOROSEAL? Yeah, I heard about that from my worker. They use that on top of bitumen for bathrooms, under topping. I'll try it out.

bro, wala akong expertise! I just ask for advice, read what's available, and try to make sense of it all. 🙂

OK OK OK, IF YOU INSIST YOU HAVE NO EXPERTISE,on what you are doing, then so much for that but then bro zepol, looking closely on your last photo, I pressume that high wall is a firewall of some sort of your neighbor and the green roofing is your house. Looking very closely at the picture you have encircled two objects from the top and I guess they are PVC pipes, yung labasan ng tubig ulan sa kanila, wow ha,madunong ang contratista na gumawa nyan, e labas ng kanilang tubig ulan ay deretso sa bubung mo at rain gutters that is why you are having floodings on your gutters.

Bro let us hope the owner of that house or building does not know the situation, kasi there is a law against this kind of construction. If you could get hold of a book on civil laws and code, it is there under the construction of facilities and that even rain water should not be permitted to flow from the roof out to the side of the other property owner. Try getting a copy from National Book Store so you may read and understand the whole content.

You can demand from them to fix it themselves since nakaka perwisyo sila.

Re: Best maintenance for rain gutters

@ rosy
hehe, I just don't want anyone to blindly take my advice because I might be wrong. I'm pretty confident in my decisions, but iba na ang may experience.

Yeah, you got the picture right. 3 inch pipes dropping down 20 feet onto my roof. You can see the new GI sheeting where the water damage must have been worst. I had ceiling damage, rotten ceiling supports, and even worse, corrosion in the steel trusses as a result. Bad trip talaga, but I'm giving the neighbors a chance to do the right thing. Thanks for the support!

I read up on thoroseal. For bathrooms, they used flintkote, overlayed with thoraseal (presumably the hyrdaulic cement). I'm not sure if it's cost effective, given the size of the gutters. The bitumen should do the job, problema lang is uv damage and possibly erosion.

My plan is to do as bryant suggested. A second layer of flintkote, then fabric. Then another layer of flintkote. Before the last layer dries, i'll drive some sand onto it's surface, then apply a very thin layer of concrete. The thinner the better, since one day the bitumen and concrete will have to be removed and replaced. I hope it's 10 years from now or later 🙂

Re: Best maintenance for rain gutters

Now I might be wrong, but I don't think it was a stroke of genius to have a roof truss inside a rain gutter. That encircle piece of steel is one end of a 15 meter roofing truss. The threaded rods fasten it to the structural concrete via steel plate. I shudder to think of the consequences of having those rust away, since that will involve having to tear down a lot of walls just to access the other ends...

This is a tricky situation. Water in the gutter can permeate into the concrete, and wet the steel plate. The flintkote does a good job of waterproofing, but needs a concrete topping to protect it. However, I think it's best if the threaded rods and plates are not encased in concrete, because in case the waterproofing fails or water gets in at any point, mabababad nanaman ang steel sa tubig. Plus, it's impossible to inspect the steel once it's nabaon.

I'm contemplating on having the palitada immediately around the steel removed, so that the steel can be painted regularly. However, without that palitada, if the gutter overflows again, it will overflow inside into the ceiling.

I will have to think this one through. I'm sure magagawan yan ng paraan. But in my experience, 'gawan ng paraan' is expensive in the long run.

Re: Best maintenance for rain gutters

Why dont you try Castle Waterproofing. I tried this sa bathroom ng Sister-in-Law ko. We conducted 24 hrs flood test walang tagas.

For a 3 sq.m bathroom. I spent the ff:
1 qrt - castle primer x P419.75
2 qrt - castle topcoat x 749.75

Total = P1919.25 (Medyo mahal nga lang.)

To know more about the product.

We are going to use this again sa other bathroom nila.

Thanks, I'll investigate. Kaso lang, my gutters will need around 150sq feet of waterproofing. At some point, it might be more cost effective to re apply bitumen semiannually, hehe.

Based on my computation you will spend P9-10K using Castle Waterproofing with the given area (150 sq.ft)

Re: Best maintenance for rain gutters

I think this does the job:
I rehabilitated a cemented-over downspout, increasing the drainage by 50%. Furthermore, I added an overflow pipe - just in case an extremely heavy rainfall coincides with high tide. In that event, the pipe ensures that the water level in the gutter never gets too high. Di bale nang umapaw into the balcony, basta not into the ceiling.

3 coats of bitumen were then added. I didn't flood test, but we observed that after the first coat, the leaking was already eliminated.

While the third layer was still wet, we pressed waterproofing membrane into the corners and especially onto the inner wall of the gutter where very porous chb and mortar was used ( don't ask me why).

Once that was dry, 4th layer of flintkote was painted on top of the membrane. I didn't use fg4, just the stuff i found at the local wilcon. Anyway the membrane is there to give the bitumen some tensile strength in case cracks in the underlying concrete form. Malamang overkill na actually.

Next step is to flatten those folds in the membrane, and embed some sand onto the still-soft bitumen. Then a thin layer of concrete topping goes on top. The concrete is there to protect the bitumen from sun and erosion. The thinner the better. My hope is that when the time comes to redo the waterproofing, the underlying fabric will make the topping easier to remove.

I decided to not use any waterproofing with the topping, not even sahara. It's not just the additional expense, I figured it doesn't make sense in this situation.
1.) if i had any doubts as to whether the underlying bitumen was enough, i shouldn't apply the topping anyway.
2.) the critical thing is to ensure that the water level doesn't reach the soft mortar halfway up the gutter. The downspouts and overflow pipe take care of that. The mortar itself was aggressively waterproofed, but in the end this area should not be subject to water ponding anymore.
3) the rest of the waterproofing is overkill, more to protect the concrete gutter from water damage
5) i had the underlying concrete overlain with sahara anyway hehe

Re: Best maintenance for rain gutters

Zebol, bro,

That's cool, you were able to fix your concrete gutteSr but then what about those two down spouts of your neighbor? they are still there and its still rainy season and still if it rains cats and dogs your roofs will still take the pounding of the rain water coming down from those pipes.

I can just imagine the loud noise or sounds when those water coming from their pipes spout falls on your roof, maybe its as if you are being bombarded by fire trucks. he he he he he , bro I was just curious.

Again CHEERS and LOTS OF LUCK !!!!! :goodluck: 😀 😀 😀

Re: Best maintenance for rain gutters

or, ask them to pay per gallon of rain water coming from their properties, Php2.50 perhaps 😀

Syempre may royalty si ossie. Idea nya, eh.

Re: Best maintenance for rain gutters

possible that those pipes are pasingawan sa bathroom. i have to wait till it rains to be sure.
