Perc Tests in PA, NJ, and DE
Most basement moisture problems begin outside the home. If you struggle with poor yard drainage, a percolation test, or perc test, from Dry Tech Waterproofing Solutions can help assess the problem to determine an effective solution. We serve homeowners throughout Pennsylvania, New Jersey, and Delaware with expert home waterproofing and drainage services. Get started with percolation testing today to protect your home.

What Is Percolation?
In soil, percolation refers to the rate at which water moves through dirt. Soils with a high percolation rate will drain very quickly when wet. Conversely, soil with low percolation may not absorb moisture at all, forcing water to pool on the surface. Your percolation rate is unique to your lawn and is influenced by a variety of factors, including:
- Infiltration, or the amount of water entering the soil
- Compaction, or how tightly soil is packed
- Soil type and composition (sandy vs. clay)
Percolation is important to basement waterproofing. As the soil absorbs water, it swells and expands. The swelling creates an outward force – called hydrostatic pressure – that puts stress against your basement walls. This stress may lead to bowed walls, heaved floors, and cracks. As your basement sustains more damage, it becomes vulnerable to water intrusion and flooding. You may even discover mold or pests as increasing moisture creates the damp habitat they seek.
Basement water may come from several different sources, and the cause isn’t always evident. Finding the right solution to your moisture problem requires understanding all the factors, both internal and environmental. Percolation testing is key to this process.
How A Perc Test Works
Dry Tech Waterproofing Solutions offers perc testing to evaluate the soil conditions surrounding our customers’ homes. As part of the percolation testing process, our basement waterproofing experts will dig a series of narrow holes in your yard. Different depths and arrangements of holes may be used to deliver a more accurate reading for your unique lawn. After presoaking the holes, we will then fill them with water and measure the speed at which they empty into the soil.
The perc test results will help us detect issues that may be contributing to a basement moisture problem, such as hydrostatic pressure or poor yard damage. This enables us to recommend the right solution to waterproof your basement. By taking preventative action, you can avoid disasters that lead to expensive repairs – saving you stress and money in the long run.
After Your Perc Test
Once we have conducted testing and evaluated your lawn’s percolation, we may then recommend an effective solution. Dry Tech Waterproofing Solutions uses several proven methods to address drainage problems and provide long-lasting water protection:
Interior Basement Waterproofing
If water is entering your basement due to poor percolation, we may apply interior basement waterproofing techniques. These include protective vapor barriers and sealants to make basement walls more impervious to moisture. We may also install a sump pump, which will help your basement get rid of excess water in case of a flood.
Exterior Basement Waterproofing
Exterior basement waterproofing can stop water before it ever enters your home. To protect the outside of your basement, we apply an advanced coating along the foundation line. This coating provides water-resistant protection to prevent intrusion. It also strengthens the concrete, rendering it durable against other environmental hazards.
Drainage Services
Poor soil percolation is often a cause or indication of poor drainage. If your lawn isn’t draining properly, our drainage services include a range of solutions to redirect water away from your home. Our methods include lawn re-grading, French drains, dry wells, and trench drains, which give water an easier path away from your home – protecting your basement from flooding.
Mold Remediation
If your basement has a moisture issue related to poor percolation, you may also have some mold growth. In addition to our waterproofing services, Dry Tech Waterproofing Solutions also offers safe and effective mold remediation to eliminate unwelcome growths. Remediation improves health and air quality, helping you feel comfortable in your home.
