Foundation Drainage Repair
Learn About our Foundation Drainage Repair Services
Foundation drainage services refers to any system designed to divert or direct water away from a foundation. Such drainage includes systems installed outside the edge of foundations as well as systems that are installed under foundations. Advanced also provides foundation drainage repair services to correct existing drainage systems.
WHY IS FOUNDATION DRAINAGE IMPORTANT?
In Texas, the ability of soils to support a foundation is greatly affected by the amount of water in the soils. The goal is consistent soil moisture. Too much water can cause soils to swell and heave or lift a foundation. Proper foundation drainage helps to keep excess water away from a foundation and to prevent problems. Advanced offers foundation drainage repair services to correct fix these issues.
DO I NEED FOUNDATION DRAINAGE?
An hour after rain stops, do you have standing water within 10 feet of your foundation? If your answer is “Yes”, you may need to consider foundation drainage repair. Does the soil next to your foundation remain muddy or soft for days after a rain? If your answer is “Yes”, you may need to consider foundation drainage repair.
HOW CAN ADVANCED HELP?
Advanced reviews foundation drainage you currently have and measures things such as the slope away from the foundation. With the survey in hand WE outline a detailed foundation drainage repair solution that may include:
Gutters and Downspouts – These are the first things added as they are the easiest way to drain a foundation.
Adjust Slopes – The next step is, if possible, to slope the ground away from the foundation. Typically a slope of an inch a foot for 4 to 5 feet is adequate as long as water is not allowed to stand within 10 feet of a foundation.
Drains – If grading is not possible, area drains, drains that collect surface water are installed. In some situations, shallow French Drains are used as a solution.
Water Direction – Advanced Foundation Repair’s focus is to, when possible, direct water into a street, drainage ditch, or swale. A swale is simply a very shallow ditch that is used to carry off water.
WHAT ABOUT WATER UNDER A SLAB?
Even when there is adequate exterior surface drainage water can flow under the surface and get under a slab. Advanced takes water control to the next level. Based on how the water is flowing Advanced uses the following approaches for foundation drainage repair:
Moisture Barriers – Moisture barriers are vertical layers of plastic that are buried in the ground. As water flows up against a moisture barrier, it is stopped and prevented from getting under a home.
French Drains – French Drains are trenches filled with gravel that have a drain line buried in the gravel. French drains are designed to intercept and remove underground water.
Under Slab Drains – Rarely, it is necessary to tunnel under a foundation and install drains in the tunnels to collect and remove water. Drainage tunnels are dug by hand and typically measure 3 feet wide and 3 feet deep.
WHAT DOES FOUNDATION DRAINAGE COST?
The cost of foundation drainage is often between $1,500 and $2,000 for recontouring a yard. French drains typically start at around $20 per foot. More elaborate drainage systems cost more.
