French Drains For Interior Basement Systems

There are different factors that can cause this problem. One of them can be water coming through the wall or there is a build up of water underneath the surface wherein it crawls upwards through the structural elements. The water can also seep into the walls through small crevices or cracks caused by pipes or electrical wire insulations. Sometimes basement windows can be the cause of water seepage as well. A strong and robust drainage system is needed to guard against such problems which are rather frequent.

Our team of experts provides an effective way to take care of the problem where in the interior French drains are placed next to footing to block groundwater before it enters the building, this is different and better than installing a gutter system that collects water after it drips on a wall. Sometimes the walls are made of blocks where water can get accumulated in the block cavities and can cause constant dripping and great damage. Drilling holes in each block cavity (called weep holes) helps drain water from the blocks and prevents water build up. This excess water is ultimately collected in the French Drainage.
