Rain, Rain, Go Away
Most of the service area covered by Polyjacking.com has had a lot more rain this summer than usual. In addition to ruining a lot of outdoor plans, the rainfall may have wreaked havoc with the foundation of your home or business.
If your building wasn’t flooded, why should you be worried about the amount of rain in your area?
Water and Soil
When there is a lot of rain, it has to go somewhere. Some of it may run into storm sewers or creeks or other planned run-off areas. Most of the time, though, it goes into the soil until the ground is saturated. The water-soaked soil can cause problems for concrete slabs and foundations.
When the soil is oversaturated, it can exert a tremendous amount of pressure on its surroundings. This is called hydrostatic pressure and it can damage a foundation wall completely. If the foundation of your building is under the strain of hydrostatic pressure, the walls may begin to bow or lean. Walls and slab floors may show cracking as the soil and water pushes against the rigid concrete.
Water will take the path of least resistance and can erode the soil around it. When the soil gets washed away, it removes the support from around the foundation or slab. Voids can open underneath the concrete, allowing the slab to sink or crack.
If the rain falls too fast or the ground is saturated, the water can flood buildings or enter cracks no bigger than a hair. Water can weaken concrete and put your slab or building in danger.
Water Damage Prevention
There are steps you can take to help keep your home or business dry. You can make sure that your gutters and downspouts are clear and emptying at least 10 feet from the foundation. In addition, companies like Pro Foundation Technology, Inc. can provide you with waterproofing techniques to keep the water out of your building.
Some options that can help with surface drainage include drywells, gutters, and French drains. It is important that you have good surface drainage or the water you keep out of your building will just come right back, trying to enter your foundation.
To properly install exterior drainage, the outside of the building will have to be excavated, exposing the footing. Most reputable contractors will roll on or spray a polymer waterproofing product. A drain pipe system should be installed for continuous drainage. The drain can empty to a sump pump system or to daylight.
One of the most important parts of a waterproofing system is the implementation of a sealed interior drain tile system. Since the system is underneath the foundation, it is important that it is installed correctly from the start. Cracks in the walls and floor will need to be sealed with epoxy or polyurethane.
Sump Pump System
A sump pump system can move water out of the building, keeping water from flooding the structure. The system consists of a sump pump, a sump pit, and we recommend a battery back-up sump pump.
My Slab is Damaged, Now What?
So after all of the rain this summer you may be facing a damaged concrete slab or foundation, so what can you do? Before you call in someone to have the slab torn up, contact the experts at Polyjacking.com. We will come out and look at your property and determine if polyjacking is the solution you need. Polyjacking a slab is a LOT cheaper than destroying it and replacing the concrete.
The process is relatively easy and doesn’t require heavy machinery. Small holes are drilled in the concrete and polyurethane foam is injected under the slab. The foam expands, lifting the concrete and filling in any voids and cracks underneath the slab. The foam is water-resistant, so it won’t erode and the foam compacts the soil, making it more stable. By the time the equipment is removed and the area is cleaned up, you can use the slab. Curing time is about 15 minutes, so you won’t have to wait long to get back to business.
