There are numerous of methods if you are trying to find ways to water-proof the inside walls of your basement: waterproofing drains, tiles, as well as other products. The cost is varied really, but it's vital that you repair water issues that have shown up as quickly as you possibly can, since this is the foundation of your house we're referring to.
So now that you understand a little bit about what's on the market, let's talk about waterproofing products. If you want to use most basement waterproofing products, you would first need to get rid of any earlier applied basement waterproofing paint, signs of water damage like mildew or mold, and you'll also need to repair cracks with a compound created for filling them up. If you have a concrete foundation, cracks in the concrete are usually the main way that water gets to your basement. What is great about this though, is that you may seal off these cracks from inside using urethane or epoxy-based products, which primarily is pressurized and injected into the cracks and mold to the openings, reducing the water's itinerary, if you will. These kinds of repairs last fairly long, and you could even get a 10-year warranty with them.
What you also could do is use waterproof membranes to your wall surfaces. They're fairly successful when it comes to cost, and if you apply them properly, they last fairly long too. You have 2 options when considering waterproof membranes: liquid or solid. Liquid membrane requires you to specifically apply it to your floor surfaces and walls. Once applied, liquid membrane hardens and forbids water from entering. Solid membranes work a bit in a different way. There are small pockets in the plastic material which collect water, which is then drained right out by way of a pre-installed drain.
When you have a foundation created from cement blocks, there is an option called an interior drain tile system. Drain tiles, while probably the most well-known and oldest method of diverting water from the basement, they're a good and effective choice. An interior drain tile system gets water from the block system and then empties the water into a sump, which will keep your basement nice and dry for quite a while.
An alternative to an inside drain tile system is baseboard drainage. While the interior drain tile system is a fantastic choice, the baseboard drainage system is significantly cost-effective. How it works is that a weep hole (or multiple weep holes, based on the seriousness of your problem) is created on the floor of your basement and collects any water which has entered. Baseboards take any water collected away to a regular drain or mechanized pump.
It's important to point out that the waterproofing products (epoxies, urethanes, membranes) are a good immediate remedy, while the drainage systems (interior drain tile, baseboard, etc.) assist in preventing water from ever touching the inside of your walls. Ideally, a mix of these methods works best, and speaking with a basement waterproofing professional on the pros and cons of each and every combination is highly recommended.
A drainage system is not exactly basement waterproofing, but it is accepted as a great way in reducing basement water. Building Officials and Code Administrators agree that it's a fantastic solution to getting rid of water. Any of these choices, when installed properly, will be a highly effective strategy for keeping your basement water-free
