What Is Drainage Systems?

Proper drainage is essential for foundation health. When water is allowed to pool near your home or saturate the soil around your foundation, it creates hydrostatic pressure, soil erosion, and the conditions for foundation settlement. PiersPro designs and installs comprehensive drainage systems — from simple downspout extensions to full French drain networks — that direct water safely away from your foundation.

Frequently Asked Questions

What is a French drain?

A French drain is a trench filled with gravel and a perforated pipe that redirects surface and groundwater away from an area. It is one of the most effective methods for managing water near foundations and on hillside properties.

How do I know if I need a drainage system?

Signs you need improved drainage include standing water after rain, soggy areas in your yard, water seeping into crawl space or basement, foundation cracks from hydrostatic pressure, and soil erosion near your foundation.
