There are several good videos on home improvement TV show sites like This Old House about this problem. To really solve it if diverting surface and roof runoff does not work, you first need to know if it is 1) coming in from under the slab, like at the joint where the slab meets the walls (high water table), 2) through wall cracks or joints (external waterproofing failure), 3) around a penetration like a pipe (seal failure), or 4) over the top of the foundation concrete or block wall (surface water infiltration). Too many possibilities to go into detail, but in summary the positive fixes are : 1) requires either an external perimeter drain installation below basement floor slab elevation (or cleanout if you already have one) or if you are in a location where a french drain has no place to drain to, then an infiltration pit and sump pump; 2) external french drain and/or external wall waterproofing, 3) remove and replace seal around penetration, 1, 2 and 4) regrade outside surface to prevent water from getting at the house.

Since it sounds like it is just a small weepage and is not actually flooding your basement with a lot of water, start with doing some surface regrading or ditching to keep surface water at least 2 feet from the foundation, and make sure rain gutters are working and have runout spouts (a 10 foot piece of rain gutter works well) to get the drainage to somewhere where it will drain away and not come back to the house. The key is to keep the water from getting to the foundtion in the first place. Unless you are in a real clayey area that will usually solve the problem if it only occurs when it rains hard. If you don't have rain gutters they are not real hard to put up, or a gutter contractor can do a typical house in a day. That keeps roof runoff from falling right next to the foundation.
