Top 10 Strategies for Ensuring Your Concrete Floors are Damp Proof and Long Lasting

When it comes to damp proofing concrete floors, there are a few tried-and-true methods of creating a waterproof space. Knowing the right techniques and spending the time and effort to apply them can save you headaches and money in the future.

First, make sure you have a plan. Take an inventory of the area and identify any large holes, cracks, or gaps between the floor and the walls. All of these areas need to be filled to create a waterproof surface. Silicone caulk is a great choice for sealing tight between the walls and the floor. Epoxy works to fill holes and cracks in the concrete, and dries clear, flat, and waterproof.

Next, consider a membrane-type damp proofing solution. You can purchase a liquid membrane, which you would paint onto the floor. When it dries, it creates a hard surface, and when a layer of the correct underlayment is applied, it forms an airtight seal that prevents moisture from permeating the floor. This is a great choice if the damp proofing needs are minimal.

For those looking for a less liquid solution, the other common method is called cavity drainage. With this approach, you place a specially designed plastic between the concrete and the underlayment. It looks like bubble wrap, with small nooks and crannies that fill with water from condensation and then redirects it toward the basement’s drainage hole.

Regardless of which route you choose, consider investing in a dehumidifier to help keep the area dry. Basements are often cool and damp, and a dehumidifier helps to remove the moisture from the air. This appliance should be used until the basement is sealed, finished and insulated.

Finally, remember that no matter how damp proofing is applied, it still requires constant vigilance to make sure that there are no new cracks or gaps. Water can find the tiniest hole and then work to make it much bigger. Inspect the area on a regular basis, and if more sealers or patching is needed, don’t wait – take care of them right away.

Damp proofing a basement floor can be time-consuming and complex. By employing the right techniques, including applying sealers, membranes, and using a dehumidifier, you can create a dry and waterproof environment that will last for years. With constant maintenance, you’ll be able to enjoy a wood or carpet-covered basement, free from the worry of water or mildew in the future.
