Pictorial Case Study

 This French Drain Trench was cut in April of 2010 in the middle of the dry season. The standing water seen in the trench is the level of the groundwater. It is within 6 inches of the surface. This is April…if the ground is nearly saturated in April, the very peak of dry season, it is certain that it is over-saturated through the entire rainy season. No wonder no grass would grow. No wonder the shrubs were dead or dying. No wonder there was such severe erosion!

This picture also shows how PDE does its work. We clean cut the sod and the trench when the sod and the soils will support a clean cut. We keep the sod on site and replace it as quickly as possible, right back where it came from. If additional sod is needed that will become part of the contract.

Clean cut trench, but crummy conditions so sometimes things can get a little messy.

We use commercial grade products for our residential projects.

Work in progress.

Back filling completed – no sod yet.

Materials laid out while trench is dug for the drain, which will eliminate standing water on the pool deck.

Work in progress.

We routed the pipeline around the tree to protect its roots.

Main trench, which includes a “T” and the discharge line to the nearby creek.

In process of turning into a French drain – eco fabric and bedding gravel going in.

One design feature we emphasize at PDE is the actual discharge end of the drainage system. We typically specify and construct a hand-trowled, concrete collar, mitered-end-system (MES).

Large drain is installed where the mosquito infested “pond” use to pool.

Tree where erosion was all around now has new soil and will be sodded.
