Almost all of our basement walls are reinforced with cement bricks/mortar/cement. We had some water come in to the basement and we removed some wood underneath the stairs and see that it looks like the basement wall under there is original and has some seeping cracks plus there is a strange hump that has a thin layer of concrete over it cracked open and is showing a pile of dirt underneath. House was built in 1905 and for the most part seems to have a very good foundation. Would like to have you look at it and get us an estimate for repair. Thank you.

Job Stories From Sioux City, IA

Full Basement Waterproofing in Sioux City, IA - Photo 1
Full Basement Waterproofing in Sioux City, IA

The customer was remodeling this home to sell to some people he knows. He wanted to make sure the basement would stay dry and that the water issues he experienced with the home doesn't cause future problems for them. Water would get into the basement when we got heavy rain. He would have to push the water over to the drain to get it out of the basement.

We used our WaterGaurd system all the way around the basement to ensure the whole thing would stay dry all the time. We put in full height clean space to limit the amount of water vapor getting into the home. We also used our triple safe pump to make sure they won't have to deal with the stress of a sump system failure. 

He enjoyed that our system would guarantee the basement space to be dry. He knows the quality work we put into homes and know we will make sure the new homeowners will have no problems. The new homeowners and he also liked that the 25-year warranty would transfer over to them.

We were able to meet with the current and future homeowners and they worked so well together to design a system that would fully take care of their needs. They were so happy that we can make sure the basement always stays dry and it won't be a problem for them. The future homeowner was worried the moisture would cause health concerns for their family.
