First we do the prep work, moving your stuff and covering it with plastic, then laying tarps across the floor. The inside perimeter of the floor, the floor that touches your basement’s exterior walls, is cut approximately one foot from the wall. Then a deep-channel trench is excavated and pitched.
If your basement walls are constructed of cinder block, then where possible, we tap the lowest course of block and install weep holes to drain water from the walls. Then fully slotted, non-biodegradable, high density polyethylene drainage pipe (also known as HDPE pipe) is installed in the trench to deliver water to the sump area.
To discharge the water, we install a 3,000-gallon-per-hour submersible pump in a covered polyethylene liner. Typically, for a basement with a perimeter of less than 124 feet, only one sump pump is needed, but two sump pumps are usually installed in basements with perimeters ranging from 125 to 249 feet.
Next, polydrain wallboard is installed over the bottom of the perimeter wall and over the entire trench in the basement. Then, the wallboard and drainage pipe are covered in gravel and the basement floor is re-cemented back to its original level.
Finally, we do the cleanup work, sweeping the floor clean, removing all debris from your property and removing the plastic covers from your belongings.
