Hello everybody,

I just joined this forum, we just bought a old house (60 years), Split level with crawl space. It has Cinder Block as foundation all around the house. At the rear of the house we have a concrete pad 4" thick 30'x12', during heavy rains I see the water gushing through the gap within the cinder block foundation throughout the house (around 50 gal/hr during heavy downpour). I fixed some of the water seepage by redirecting and cleaning gutters and drain pipes. I have noticed that there is a 3/4"-1" gap between the concrete pad and the foundation. The foundation is not sloped properly so water tends to stagnate on the pad during rains and may be flowing through the gap into the crawl space. There are also big gap between the the steps and the concrete pad.

What is the best way to seal there gaps?

Thanks

 

is the pad separate from the foundation (as in added later) or is it part of the foundation? you really need to get the pad sloped away from the house, or you might need to add a sump at the point where water stands and pump it away from the house, are you saying that the foundation is in places elavated above the slab? if so you could tuck point mortor into the gap to help seal but you still need to make it so water can not stand close to the house.

if we're not supposed to eat animals why are they made out of meat?

 

Thanks for your reply.....

The foundation and concrete slab are not integral, the slab must have been laid at some point after the house was built. It does look in decent shape except for a few minor cracks and gaps under the steps.

What is the best way to create slope on an existing concrete pad?

I was planning on filling all gaps using concrete since the gap are sizable but was worried that when the concrete does expand and contract they would exert pressure on the cinder block foundation of the house causing damage. I will also try and channel the water away from the house by cutting some shallow trenches (any problems doing so).

Thanks
