In order to control moisture from the cove joint of the wall and the floor at the perimeter of the basement, we broke out the concrete floor, and drilled weep holes into the cinderblock. This will drain the wall at the cove joint so we can control where the water enters the home. We then installed drainage stone and the WaterGuard system to the trench, and concreted over the system. The SuperSump pump was plumbed to the back corner of the home and discharged to the outside, through an Iceguard and a buried drain tile 12 feet away from the house by the fence, terminating in a drywell box...
Finished Wall Anchor on the exterior. Very minimal disturbance to the ground.
In order to stop groundwater seepage onto the basement floor, we jackhammered out the perimeter of the basement, and hauled away all the concrete and related debris. Next we dug a trench and drilled weep holes (in the block walls). We then laid out filter cloth in that trench to minimize sediment getting into system and installed our WaterGuard system on the foundation footing, and finally backfilled with river rock stone, and mortared over the top. We also broke out the floor and dug down around the existing sump pit and installed a professional basin with drainage stone and a...
CleanSpace Encapsulation will trap vapors rising from the ground, below its 20 ml liner, and will create an environment where you can control the humidity.
SuperSump
In order to channel water away from the garage, we installed a Trench Drain in front of the garage. We tied that into an existing drain that would redirect that water to an area away from the garage.
The WaterGuard solution is designed to control perimeter water from the cove joint, and redirect that water to a sump pit. We broke out the concrete around the perimeter of the foundation, and set and installed a sump pump. Then we re-concreted over those areas. Then we plumbed the sump pump to an IceGuard, that transitions plumbing from 1 1/2" plumbing to a 4" discharge line. To avoid water from backing up into the interior system, the slots in the IceGuard allow water to escape if the 4" discharge line were to completely freeze. To finish off the walls, and to also...
Painting basement walls can look nice, but over time flaking and staining can occur. Our BrightWall walling systems act as a flashing for foundation seepage, and also cleans and brightens even the darkest of basements!
