If water leaks in your company's basement each time that it rains because of a thin gap around each window, use caulk to waterproof each window's perimeter. Afterwards, provide the entire basement with a waterproof barrier by adding a coat of concrete sealer over each interior wall.

Remove Dirt From Interior Walls And Apply Caulk Around Each Window
Make a cleaning agent by filling a bucket with warm water and adding some industrial-strength detergent to it until the solution has plenty of suds. Dip a sponge into the cleaning mixture and use it to wipe away any smudges or stains that are on the basement's interior walls. Use a sponge that has been soaked in plain water to wipe the soapy mixture from each concrete wall. Dry the walls with a lint-free towel.
Place a tube of caulk inside of a caulk gun. Apply a thin layer of caulk around the interior side of each window. If too much caulk has been administered around any of the windows, remove it with a damp sponge. Use a putty knife to smooth out the caulk that was applied. Wait for the caulk to cure.
Waterproof Each Interior Wall
Use drop cloths to line the flooring that is next to each interior wall. Place strips of masking tape over molding or any part of the building's interior that is near the concrete walls. Fill a tray with waterproof sealer that is designed for concrete. Attach a paint roller to an extension handle so that you will be able to apply sealer to portions of the wall that are out of your reach. Dip the roller into the tray to evenly coat it with sealer. Move the roller across each wall in lines. Add more sealer to the paint roller whenever it is needed.
If there are parts of the wall that cannot be covered properly with a roller, use a standard paintbrush to apply sealer to them. Wait for the sealer to dry before adding an additional coat. Once the second coat of sealer has dried, remove the masking tape from each wall and lift the drop cloths from the floor. Your company's basement will now be sufficiently protected from moisture.
