In order to install/anchor a new toilet flange correctly I plan to pour cement to fill in the space between the drain and the existing concrete. This should prevent toilet leak from entering below the tile and slab. 1. Since the ABS turn is visible and only partially under concrete, can I pour concrete directly on to of the ABS?
Hydraulic cement is a generic product that offered by many suppliers in different bags with different company logos on them. It has been used for decades on commercial, industrial and civil (dams, etc.) for crack repair and the slight expansion to create a tight seal even when applied to damp concrete.
Yeah, I think the roofing cement idea would work but I think it is gross overkill. Hydraulic cement (hydroplug) is a waterstopping cement product you can buy in small dry mix buckets at home centers. Mix it to the consistency of peanut butter and pack it in the annulus around the pipe from both sides. It will make a very tight and watertight seal.
Hydraulic cement cannot expected to be a match for other concrete. It is a different product with different raw materials and proportioned. It is very probable that the cement is not at all the same chemically as regular cement.
DAM-IT seams to be an answer, hydraulic cements, epoxy's specifically for use with water all seam good solutions as well, but the pipe is plastic, so what works best with a plastic double wall pipe configuration with a 1/2"-1" vertical slash in it with water coming out?
What is the best way to patch this so it will withstand the extremes? The roofing cement seems to work well and has prevented any water. However, as my photoes show there is more patch breaking up. Should I just remove the broken up concrete patch and put a good layer of roofing cement or would hydrolic cement work better and be more permanent?
Would hydraulic cement be right product to use to reduce the flow or is there a better solution? Picture not the best; my memory is 3/4" copper line coming out of poured concrete wall with 3/16" or so of space around the tubing.
Yes, hydraulic cement would stop (some) water for a (short) period of time after you carefully prepare the crack digging it out as a reversed "V" and then pack the cement in really well. Unfortunately, the truth is that the water is coming in from outside - therefore it will simply find the next easiest place to come in.
Hydraulic cement is good, but if the hole is deeper than a few inches, you may not get a good seal. Sika 10.1 fl. oz. PowerSet Concrete Gap Filler Repointing Masonry Repair and Concrete Gap Filling 7116190 - The Home Depot
Hydraulic Cement is a product used to stop water and leaks in concrete and masonry structures. It is a type of cement, similar to mortar, that sets extremely fast and hardens after it has been mixed with water. If it still leaks after that, dig down the outside and add a peel and stick around the pipe to seal it.
