Why A Drainage System is Necessary

Water can leak into a home through the foundation during many times of the year, including those with heavy rain or when snow from the winter season begins to melt. Gutters that were not properly installed or have become damaged are not able to push water away from the home. As a result, the soil surrounding the foundation becomes oversaturated with moisture. The over saturation allows water to seep into the home through new or existing foundation cracks, or through the cove joint where the wall meets the footing. This can lead to a variety of problems such as fungus growth, destruction of personal possessions, or even structural damage to the foundation or the home.

What is a French Drain?

A French Drain is typically comprised of a perforated drain pipe placed within a trench and covered with gravel or a gravel-like material. The French Drain is used to redirect surface and ground water away from the home. Depending on the home, the costs of this type of drainage system will vary, but projects can cost upwards of $1000. Unfortunately, French Drain systems can be prone to clogging and are not as reliable as MDTI’s recommended solution – the Hydraway Drainage Solution.

What is Hydraway Drainage?

The Hydraway System has been manufactured by MDTI for over 20 years. The popularity of Hydraway among contractors has continued to grow because it works better than any other draining system on the market. The Hydraway Drainage System protects basements and crawlspaces from water that may enter.

The Hydraway Drainage System is comprised of three separate parts:

  • Hydraway 2000
  • Hydraway 300
  • Hydrapump

First, the Hydraway 2000 removes the water from the foundation. Instead of a standard pipe made of plastic or metal, Hydraway 2000 is made of a special geotextile fabric that is completely clog resistant. Once it has been installed in the problematic area of the house, it serves to stop water from entering the foundation before any damage has a chance to occur.

The next piece of the system is the Hydraway 300. This component captures water at the cove joint, or where the footing of the foundation meets the wall and the floor. This is the weakest part of the foundation. The Hydraway 300 acts as a bridge for the Hydraway Drainage System, directing water down to the Hydraway 2000.

The Hydraway 300 can also be used as a completely separate component, independent of the Hydraway 2000. If needed, it can be used for drainage on retaining walls, exterior foundations, planter boxes, landscaping, and sub-slab construction.

The final part of the system is the Hydrapump. The Hydrapump is MDTI’s brand of sump pump that captures water from the Hydraway System and redirects it through the exterior of the home using PVC drainpipes and discharge lines.

The Hydraway Drainage System provides time-tested waterproofing protection to any home. It prevents water from seeping into the basement or crawlspace, ensuring the foundation remains structurally sound.

Advantages of Hydraway Drainage

  • The Hydraway 2000 is guaranteed not to clog, as opposed to French Drain systems.
  • Hydraway’s geotextile fabric of allows for water to flow 70% faster than standard systems, leading to more protection.
  • The installation process offers very little disturbance to the existing foundation.
  • The system also allows for the release of hydrostatic pressure to ensure the foundation is structurally intact.
  • As shown to the right, installation is quicker and easier with Hydraway as the required trench excavation area is smaller than French Drain systems of pipe and rock.

Perforated Pipe vs. Hydraway

The photo on the right shows a failed perforated pipe system (left) that has been clogged and caved in because of its lack of strength. Hydraway is shown on the far right, which has high composite strength due to its polyethylene core.

Hydraway’s unique design allows for 85% available open space for water intake. Take a look below at the chart for more comparisons between traditional perforated pipe drainage and irrigation systems and the industry’s best – the Hydraway Drainag System.

Perforated Pipe Hydraway Drainage
Installation Cost Per Linear Foot $6.50-8.50 $1.75-2.25 (80% Savings)
Soil Infiltration Easily Clogs Will Not Clog
Labor Labor Intensive Quick Install
Open Surface for Water Intake 4% 85% (open on all 4 sides)
Draining Speed Slow Rapid
Average Trench 8″ wide by 12-16″ deep 3″ wide by 9″ deep
Backfill Clean Rock Coarse Sand

Flow Rate Demonstration

There are several french drain options available on the market today. However, none compare to the compressive strength, guaranteed results, and in-flow rate of the Hydraway Drainage System.

Flow ratings are only a measure of how quickly water flows from the pipe. A more important question to ask is, “what is the in-flow rate?”. The video below demonstrates in-flow rate of standard drainage options and the Hydraway 2000 6″, both single and double layered.

System Flow Rating/Linear foot Per (ASTM 4716) “In-Flow” Rating (or Permeability Rate) in % of the openings across the surface 4-gallon Bucket Test (Time elapsed in seconds for water to empty)
4″ Perforated Pipe 32 gal 4-5% 27
Gravity (WaterGuard) System 8-9% 23
Hydraway Single Layer 10.5 gal 75% 11
Hydraway Double Layer 10.5 75% 6.5
