TerraDry Waterproofing Technology

Moisture: In so many facets of life, it can be a wonderful thing. In our natural environment it sustains plant and animal life and keeps things looking lush and green. In our homes, the right level of moisture keeps the air pleasant. Even in our bodies, the right level of moisture is required for proper functioning. Too little, and our skin gets dry and cracks and lack of correct percentage of moisture internally can create havoc. Our eyes become red and itchy. But there’s one area where moisture (especially too much of it) can cause some serious problems: roads and pathways or any hard surface that will receive traffic.

When it comes to building proper roads and pathways, moisture must be at a fairly precise level. While a range of 7-14% is acceptable in the base aggregate, around 12% is ideal. At this level, the aggregate is just damp, which is perfect for making a road. The issue that so often arises is that it is nearly impossible to maintain this percentage of moisture. Changes in the weather bring along wind, rain, elevated humidity levels, and temperature, which all impact moisture levels. When soil becomes wet, water molecules separate soil particle bonds, thus becoming destabilized, eroded, and muddy. When this occurs, load bearing strength is diminished and the roadway loses its solid foundation.

To combat this problem, we developed TerraDry®. TerraDry® waterproofing technology hydrophobizes soil and aggregate particles making them completely waterproof so there is no moisture penetration. With no moisture penetration there is no mud, no erosion, and no loss of structural integrity.

Up until now, fixing moisture problems in aggregate was a costly and time-consuming endeavor. Once a road or pathway became damaged, the only way to fix it was to dig it up, haul out the inferior aggregate, and replace it with proper materials. TerraDry® allows for the existing aggregate to be treated in place. As TD permeates into the capillary network of the inferior aggregate, it fills this network of moisture channels with resin, thereby transforming the poor-quality road base into strong, stable material. No need for digging and hauling, and no need for purchasing expensive, new material. Lowered environmental impact also results. It’s a win-win.

TerraDry® waterproofing technology is also an excellent choice in areas that go through a lot of freeze/thaw cycles in the wintertime. Equally (if not more) damaging than erosion is freezing. As thawing temperatures allow moisture to penetrate beneath the surface of a road or pathway during the day, this moisture then freezes and expands at night, cracking and heaving the road, and creating a serious issue for its stability and function. TerraDry® prevents capillary water uptake, eliminating the destructive force of freezing water.

With TerraDry® you can not only prevent costly damage from happening in the first place, but save time and money on any repair projects that may come your way.
