Foundation Repair Guidelines For Homeowners Groundwater Control Part 2

This article is the forth installment of the Foundation Repair Guidelines for Homeowners series. The first three articles covered information on structural repair, site analysis, foundation repair proposals, preventing foundation damage, and basement leaks. Part one of this article discussed the importance of ground water management, not only as essential to a complete foundation repair plan, but as a proactive approach to preventing foundation damage and basement seepage from occurring. Groundwater Control Part 2 discusses passive groundwater control strategies and repair solutions to relive or eliminate excess hydrostatic pressure present on your foundation. www.geocraftbuilders.com

The best approach to correcting water seepage, moisture issues and in certain cases, preventing the need for foundation repair is to remove or control the source of the problem in addition to repairing the foundation. As previously noted in my last article lack of proper drainage causes pooling water around your basement which leads to hydrostatic pressure on the walls. Hydrostatic pressure can result in foundation damage, allowing foundation walls to crack, deflect inward, settle vertically, and allow water infiltration into the basement or crawl space of your home. Common examples of basement seepage issues are foundation cracks, slab floor cracks, tie rods leaks, and pipe penetrations.

A great number of foundation repair and basement waterproofing problems can be controlled by handling rainwater and surface drainage properly to redirect the water away from the foundation. Even when foundation crack repair, subsurface drainage systems, and steel pier underpinning is required, removing or controlling water at the source is necessary.

The most basic solutions to relieving groundwater pressure include redirecting surface water away from the structure. There are numerous methods that can be utilized for groundwater control based upon the existing site conditions. The groundwater management systems discussed in this article focus primarily on the maintenance of existing drainage systems.

Maintaining Gutters and Downspouts:

Maintaining your existing gutter and downspout system is an important step in groundwater control. Clogged gutters will overflow causing rainwater and roof runoff to free fall one or two stories to the ground surrounding the foundation. Water leaking into the ground near the foundation of your home is undesirable, as it is likely to erode the soil and backfill and create excessive hydrostatic pressure. Additionally the water seeping into the soil can lead to settlement of the foundation caused by variations to the soil moisture content.
