    Comments about Thoro® Waterplug Hydraulic Cement:

    A 30 year old shower developed a slight leak at the drain. When I removed the drain basket, I discoved that it had been installed with oakum and lead ring around ABS pipe! The gentleman at Ace Hardware suggested that I try hydraulic cement for the repair. Worked like a charm! No leaks, and solid as a rock......literally!
    The perfect solution for this unusual project requirement.

    Comments about Thoro® Waterplug Hydraulic Cement:

    This product works great. It will fill holes other products won't. I wouldn't use it on a large hole. Cracks less than 3/4 of an inch are it's best use. Around conduit or pipes through a concrete or brick wall is what I used it for.
