Sorry... kind of a long winded poster here. I live in rainy Vancouver in an old house that has poor drainage. We had a big storm yesterday with enough rain to keep the basement sump pump going frequently until late evening. I've been thinking of using my attached garage as a workshop and today while cleaning out some junk I found small puddles underneath some non-porous items lying on the floor (buckets, plastic garbage bags etc). It seems there was enough moisture under the concrete slab that some migrated up to the top and condensed in these few spots. This has happened a few times before during these really intense downpours we get 3-4 times a year.
I dread the thought of digging up around the garage perimeter to attempt fixing or enhancing the existing drainage system. Will this periodic excess moisture present many problems in the shop, even with good heat and ventilation? I've been thinking of laying down a wood floor anyway because the existing slab is quite sloped, so any power tools I plan to buy would be a few inches above the concrete.
Your suggestions and comments would be appreciated.
