Subject: best way is to correctly fix

best way is to correctly fix a 4f area all the way to the footing. check for wires and get inspected before u dig always;after u dig to the footing very important make sure its dry and clean. then apply concrete moulding into the crack wait to fully dry. then apply concrete sealer tar 4f area by 6ft in most cases. make sure its all smooth appleyed. no big dips.then apply manbrain for concrete. make sure that is stright and smooth then apply more tar on the manbrane then put a sheet of styroform to protect the menbrance and final tar form the dirt. after that u text the hole. let run the hose in the hole five min. then go check inside. if no water good job. thats hows it done portuguese way.

A epoxy crack injection is not a temporary fix if done right. I've never had one fail or have to go back to fix one. A better solution for crack injections is to use polyurethane instead of epoxy depending on the situation.


Subject: epoxy injections

I have been a water proffer for about 13 years. I have done commercial and residential polyurethane injections. I have to agree with Nathan i have never had to go back to redo an injection job. Even when I drilled a hole and water shot up 6 inches from the floor.


Subject: epoxy injections

I really have to agree with you. I've been a water proffer for 13 years, and have done nothing but injections with a polyurethane both commercial and residential. where the water would shoot up 6inches from the concrete floor after drilling a hole. The material i used stopped the water 100% and is still holding strong. I have never had to go back to fix any of my injections. Just saying

Interesting article, there is a lot to think about when making a big change to your home. Waterproofing your basement would improve you home and maybe prevent some other issues from coming up in the future but there is no guarantee!

Mold in a basement is a common problem. My company helps people with this every day. Some of the answers you received were helpful but not all the information is correct. First, you need to eliminate the two main ingrediants that mold needs to survive. The first one is water intrusion. This is a must. I am assuming you have no water intrusion as you make no mention. The second componant that needs to be eliminated is moisture. Moisture is also humidity. Basements need to be kept airtight in the summer months. Some folks have posted that you need air flow in your basement. Nothing could be furthur from the truth. When you open any windows for example, not one micron of air goes out of the basement, Warm humid air is sucked into the basement. Houses suck air into the basement and it meets the cool surfaces and skyrockets humidity. The windows must be kept closed and a dehumidification device installed to ensure humidity stays below 60% humidity. The dehumidifier should be energy star rated and purchasing a seperate humidity guage is a must to monitor the unit's progress. We like to keep our customer's basements at 50% humidity. This eliminates the smell that is active mold spore growth. Once the water and humidity is brought under control. Remove the organic materials that have mold on them. Walls, sheetrock and studs that have been affected. Follow the advice of previous posts as you must ensure that you do not affect the rest of the home. Once removed, install new walls using as much inorganic material as possible. We also install vapor barrier over the walls and seal the floors to stopwater vapor transmission into the basement. Poly plastic is not a acceptable vapor barrier. It is not "zero-perm" and will still allow moisture transmission. It will also crack and break into pieces over the years. A PVC liner rated "zero-perm" is the correct product in this application. Depending how large the basement is and if it is sectioned off will determine the dehumidifier strength. We use the Santa Fe line of dehidifiers as they are super energy efficiant and work like a dehumidifier on steriods. I hope this helps and I wish you the best in Basement Health!

Where is the home located, what is the exterior wall construction and type, how is the space heated?


It could be a whole host of different scenarios that would generate that result.  It is nearly impossible to tell but I would say that most basement moisture problems are a result of bulk moisture intrusion or condensation issues. 


Given the deep and hard winter this year, it could be a condensation issue that hadn't previously been shown.
