Addressing drainage systems

By Hawaii Renovation Posted in: BackyardExteriorIssues

Not only do heavy rains often result in flooding, but they can cause other serious, long-term problems as well. Inadequate drainage can allow water to sit on the ground for days, which can create sanitation and health hazards, while water flowing too rapidly can cause a loss of ground cover and deep erosion. Many people in Hawaii have houses on slopes, and if water flowing downward through your yard isn’t properly routed, it can wash right under your home, eventually weakening its foundation.

The key to a good drainage system is to have it move water quickly. At Lanai Scapes, experts are up to the task of installing drainage systems, and they will determine the best method for properly draining your property. This is important to help relieve the pressure from either heavy downpours or rain that continues for days.

Lanai Scapes uses an LEED drain system, which is considered the most environmentally friendly and sustainable of all systems. It consists of a light PVC pipe — approximately 3-4 inches in diameter — that runs through a trench that is 12-18 inches deep. Proper location of the ditch is an important consideration in assuring that water will flow into it.

After the ditch has been dug, the professionals lay in a filter fabric. A gravel base of about 3/4 inches is put onto the filter, and then the pipe. Gravel is put over the pipe, then another filter fabric. The trench is covered with dirt that contains organic matter. Since most soils in Hawaii have a clay-base and are very heavy, the company puts a swell on top of the dirt and plants grass on top of the swell.

The drain will catch a lot of the water from a rainstorm and the additional gravel will provide extra drainage. The drain has a port system, which serves to pull water into it when it is functioning properly and releases water out at the bottom end through a special pop-up system.

Lanai Scapes prides itself on being knowledgeable about the different environments in Hawaii and can custom design any system, whether it is for drainage, landscaping or any other aspect of outdoor living. The company can help you make the best decision by showing you the practicality as well as the cost of each of the options.
