Water and moisture in the wrong places can cause molds to grow, walls to crack, and damage to collect in the structure of your home. Your walls, roof, bathroom, and especially your basement are weak points through which moisture can seep into your walls, ceiling, and foundation.

Waterproofing your home can however be expensive. How do you keep moisture away from your home without breaking the bank?


To diagnose the direction of moisture flow, tape foil on your basement wall for a few days. Moisture on the inner side means humidity is coming from the outside into the basement. Moisture on the external surface of the foil means moisture is coming from inside the basement.

Seal Leaks and Cracks

Seal dryer vents with foil tape and insulate pipes to stop condensation. Look into high density, closed cell foam insulation as an affordable and convenient way to add insulation wherever it is needed. You can quickly touch up areas where the insulation has worn thin or you notice visible cracks in the corners between adjoining walls.

Create Slope

Most of the water that gets into your basement comes in through the foundation. Create a slope on the ground to divert water away from your foundation. It should be 6 ft wide and slope 4 inches from the foundation.

Gutters and Spouts

This is another inexpensive way to keep your basement dry. Clear gutters of all debris. Make

sure your gutters have down-spouts. Add horizontal extensions at the lower end of the down-spouts to drain rain water away from your foundation.

Drainage system

This is a must have if you are to keep your basement waterproof. It consists of a drainage sump, a pump and a drain pipe installed under the floor.


Fill holes and cracks on walls using hydraulic cement or expanding polyurethane. Waterproof walls using waterproofing coatings. For these to be effective, they must be applied on the bare wall.


Wall Tiles/sheets

Waterproof walls with single sheet plastic or tiles. Tiles now come in sheets so you can easily install them yourself. You may also use acrylic sheets or laminate tiles/sheets. Acrylic sheets are normally easy to install and come with in-built shelves.


Simple paint will not cost much and will get the job done. Use oil-based waterproof coating paint.

For the bathroom floor, apply primer. Once the primer is dry, fill cracks with silicone. Pay special attention to joints. Give the silicone 24 hours to dry. Apply waterproofing agent, stick waterproof membrane followed by more of the agent, focusing on joints.

Balcony & Roof

For the balcony and roof, use clear waterproofing membrane and waterproofing paint. The trick to making waterproofing affordable is to do small waterproofing jobs yourself on a regular basis. Coatings, paint, tiles and gutters do not cost much.
