Heavy, non-stop rainfall saturates soil to its maximum water content. Once this happens water is no longer absorbed into the soil strata and stays on the surface. If you have proper drainage, this shouldn’t be a problem because water will flow into ditches and other infrastructure assets. If you have poor drainage the water will pond. Ponding is an aesthetic problem, unless you get ponding against your foundation, in which case you should contact us for a free foundation inspection.
Ponding against your foundation can negatively affect the soil structure along the perimeter of you home and could lead to foundation problems as well as wood rot and cosmetic issues. If you have ponding next to your foundation you should re-grade the soil so that water drains away from you foundation. Ponding water is bad for your foundation because it weakens the soil that supports your foundation. The soil below your foundation was prepared for even weight distribution. Ponding and oversaturated soil disrupts this harmony. In extreme cases, water could get below your grade beam and start to affect the interior areas of your foundation. It’s very hard for the soil beneath your home to dry-out because it isn’t receiving sunlight. In addition water pockets do become stagnant and odorous.
Knowing that water drains isn’t enough, it’s important to know the path that water drains. If water is draining along your foundation it can erode soil. Continued erosion creates voids and more space for the water to occupy. Typically this is a problem around un-vegetated areas because root structures are able to hold soil in place. In extreme cases water flow can create pathways underneath foundations, driveways and sidewalks.
URETEK can fill hard-to-reach voids like those beneath homes or driveways with our polymer injection process. URETEK’s polymer injection uses expanding, high-density polymer to fill and stabilize soil. Our polymer is injected from above the slab and seeks the path of least resistance as it expands. The polymer we use is hydro-insensitive and closed-cell so it doesn’t lose strength in wet our high saturated areas.
