An exterior drain tile system is your best option if it's not pratical to waterproof a basement from the inside, due to having an already finished basement. This process starts by excavating a trench next to the foundation wall, then we apply a rubberized waterproof coating (30 year warranty) to the wall, next step we install a filtered PVC drain tile that will drain into the sump pit (pictured below). Next we backfill with 12'' of washed gravel, filter paper to help prevent dirt from clogging the drain tile, then backfill with the existing soil.
We can remove concrete or asphalt diveways, walkways or patios if necessary. In most cases we will excavate by hand to reduce damage to your landscape, and we will leave an acceptable grade tapering the soil away from the foundation.
