How to change ground/grading beside our place to avoid water pooling onto our walls?

the ground/grade beside our townhouse unit at our condominium complex slopes towards our wall and have water pool on it when it rains. we're concerned that it may be the reason for moisture at our basement walls. we're tired of waiting for the condo board to act on our request to have it updated, so we're planning to work on it ASAP.

what materials do we need to get it done? the ground on that side is just plain grass and typical soil.

Water pooling at your ground level wouldn't cause ';leakage'; into your basement - improper grading and materials used for the water proofing is the major cause. You need ';Mike Holmes'; - if your wall was done incorrectly - what are the chances that the rest of the condo was done right. You might have to wait until the ';dry'; season to have this problem addressed. Meanwhile check with your neighbors and see if they any problems with their units.How to change ground/grading beside our place to avoid water pooling onto our walls?
You need to put some more dirt in there which slopes AWAY from the wall or build a dry well into which the water can drain into another direction.
You have to build up the ground so that it slopes away from your exterior wall.

First, check to see if downspouts from the roof gutter is dumping water against the foundation. If so, you can get splash blocks to get the water to run away from the foundation.

If the grass grows up against the foundation, you will have to build the ground up slowly or you will kill the grass.

If possible, what I would do if it is OK with the association, is dig out the grass, put in top soil and make a planting bed after I had the soil built up. Plants will have roots that hold the soil in place plus it will look nice.

Another thought is a french drain. I did this on a flagstone patio that abutted my house. Simply, it is some drain boxes with grates that are connected with flexible hose that lead to a pop up valve that is at a lower elevation. All parts can be bought at Home Depot, Lowes, etc.
