Water Leaking Into Basement From Front Porch

Photo of the original porch attached the crack patches are clearly seen.

Water leaking into basement from front porch.

The house is in zone 6b. In cold climates insulating basement walls also saves energy and reduces your heating bill. You ll just create a potential mold problem. We ve been having some issues with water leaking into our basement under our front door.

But don t cover the walls with insulation if water is leaking in from outside. The basement is unfinished and the place where the water drips is clearly visible. My front porch is concrete and is above a portion of my garage laundry room and a basement bathroom. The rooms are not finished and i am not sure of the ceilings construction see photos.

Insulate exterior walls to prevent condensation. I have gone over my caulking job and re applied sealant in areas where it seemed thin. There are a number of weatherproofing issues we need to address but the most urgent is the concrete sill under the door which has been crumbling for a while and presumably is the source of our leak. This original concrete slab was not reenforced.

I m concerned that the leak may be coming from a fault in the concrete itself so i m looking at waterproofing the slab but i m unsure of what product s or techniques to use. In this post i will cover the reasons why block foundations leak and the how to fix a leaking cinder block foundation wall. 5 to 0 f. We have a metal threshold over a concrete sill and our front porch is a concrete slab about 4 x6.

The water leaking down saturates the wood between the tongue and groove. When bad rain storms hit and the wind blows just right the covered roof offers little protection and the rain leaks into the basement. However it was not long before it started leaking water into the cellar. So long as the wood framed porch had a slope built into it allowing it to shed water to the outside of the building any water that penetrated through the tile floor around the waterproof substrate under the tile and around the large corner support column would have just eventually made it to the outside and never touched the wood.

During the winter months blowing snow sits on top of the porch then on slightly warmer days it melts and leaks into the basement.
