Many people have basements in their homes and use them for recreation or storage areas. Some even turn their basements into a small apartment for in-laws or to rent out. Still others use their basements as a business or hobby. There are those who set up woodworking shops, darkrooms for photography, sewing rooms and storage space for items sold over the Internet. The point is many people who have basements use them as valuable space in their homes, and a basement needs to be waterproofed in order to protect valuables that are used or stored in this below ground space.

Water damage can reek havoc in basements. If there are leaks in the walls and a heavy rainstorm strikes, the chance of anything kept in the basement getting damaged is almost a guarantee. One small leak or excessive moisture could also create problems like mildew and mold, which will grow and spread to everything in sight. Water, mildew and mold will damage pipes, electrical outlets, walls, floors, furniture, clothing, carpeting and just about anything a basement holds.

That's why waterproofing basements is so important. Better to waterproof than to have to replace or repair the damage that can occur without it. If homes are air-conditioned, it's very important to regularly check these systems to make sure they are functioning properly. Replace filters if they are dirty and clogged. This is a major step in preventing dampness, mildew and mold. Make sure that all pipes in the basement are insulated in order to prevent condensation and moisture build up, which also contributes to mildew and mold. Install back up systems like sump pumps, which will come in hand should flooding in the basement occur. Check all walls for water stains or leaks and treat them promptly with a sealant if any are found. Check home foundations to make sure there are no cracks or open spaces. Cracks in foundations whether in new or older homes are not uncommon and will not only allow for moisture buildups and water entering, cracks can also compromise the structure of homes.

In most cases, waterproofing basements effectively takes professionals to do the job. Professional waterproofing companies know what to look for and how to fix it using state-of-the-art equipment that most people simply don't have access to. Reputable companies specializing in waterproofing basements are certified and will always provide written estimates with a breakdown of what it will cost to inspect, repair and waterproof.

To evaluate what needs to be done, waterproofing companies will determine the conditions of home basements. They will then recommend the best waterproofing systems depending on their findings. They may recommend an interior system, which in installed beneath sub-floors in basements. These systems are often referred to as French drains. Drainage pipes are placed strategically with dirt allowing for the systems to channel water away from the underground areas of homes. The water is removed by using sump pumps, which eliminates water via a pipe which is installed above foundations.

Other systems that can be utilized are installed exteriorly. These are placed on the outside foundations and require deeper digging of the area around foundations. Gravity, rather than sump pumps is the force in these systems driving water away from home foundations. This process will be followed by recommendations to install dehumidifier systems in basements in order to keep areas dry and less prone to mildew and mold.

For those brave souls that choose to take on do-it-yourself projects waterproofing basements can be challenging, but can be done. Make sure the proper tools are on hand like cement, chisels, hammers, brushes, weep pipes, glue, hoses, drills, trowels, spray nozzles, gloves, and waterproof mixes. The objectives are to stop leaks and seepage, mend holes and cracks, repair leaky floor joints and waterproof walls and floors. Fill cracks with waterproofing mix or cement, depending on sizes of holes. Chisels will be needed if water seepage from pressure has caused the cracks. The cracked areas must be enlarged in order to fill with cement. Chip away any old cement around holes and fill, mixing water to stiffen the mixture with two parts sand and one part cement. Weep pipes may also be necessary if the water seepage is caused by pressure, allowing for trapped water to move away from the foundation.

To waterproof walls and floors after repairs are made, wet the areas and remove all paint with sander and brush. Apply waterproof coating to dry surfaces covering all areas, paying particular attention to baseboards and lower part of walls. When finished, spray with water and let dry overnight. Following day, repeat spraying and apply second coat of waterproofing material.

If leaking floor joints need repair, apply waterproofing mixture to the pipe joints. If the water entering from the pipe joint is heavy, cut around the joint at the point where floor joins wall with chisel creating a groove for waterproofing material. After waterproofing application, apply cement.

It is important to note that before starting any home repairs or improvement projects, owners should check with authorities to review any restrictions or codes that may apply. Homeowners choosing to waterproofing projects themselves, should receive detailed instructions from a reputable waterproofing dealer or the National Retail Hardware Association (NRHA) for safety and accurate project results
