Expert Basement Repair

Interior waterproofing is really not waterproofing at all. It is water control. Water is still coming through your walls but being drained and directed under the floor before it enters the room. This option is frequently called for when outside additions or structural elements are in the way, or a less expensive alternative to outside waterproofing is desired.  Sometimes there is a need to remove water which is trapped below the floor that an exterior system cannot evacuate.

 Water entering the basement  is usually most obvious at the joint along the bottom of the basement wall or along expansion joints. Water beneath the floor can also push concrete upwards as the soil below swells, cracking the floor and then flowing into the room. Interior floor cracks and open joints can also allow radon gas to enter the home. Be aware that this particular service can allow mold and mildew to grow inside your walls and raise the humidity levels in the basement. There is also a tendency for these basement walls to crack and bow since the hydrostatic soil swelling outside in the soil is not really addressed. The soil is still wet as the water passes through it. A sump pump is almost always installed to collect the water and pump it outside. A battery backup pump is a good idea if you ever have power outages so your basement won't flood. This method of water remediation is our least desired, but works well to keep the interior floor dry.  Often a white plastic panel is installed over the wall to direct surface water into the floor, hide any wall damage or discoloration and dress up the walls with a maintainace free bright surface.
