| Since historic times, civil engineers have used crushed stone or a combination of stone and pipe for soil drainage. Although this method provides satisfactory results, it has some major limitations when compared to prefabricated systems. The most important characteristic of any sub-surface drainage system is its ability to collect water from the surrounding soil. The water has to be collected before it can be drained away |
| |
| - Pipe has small slits for water to enter - approximately 3% open surface area. |
| |
| High Material Costs - Stone is heavy and has to be transported to the job-site. |
| |
|
Labor Intensive - Highly dependent on skillful installation.

SITEDRAIN HQ prefabricated drains are constructed using a patented formed polystyrene core designed specifically to transition water collected from sheet drains into a high-flow collection system. The graduated, molded core has a nonwoven filter fabric bonded to one side and prevents soil intrusion into the flow channels. SITEDRAIN HQ functions as a direct replacement to costly perforated pipe and stone systems. By design, SITEDRAIN HQ is equipped to handle the water volume generated by prefabricated sheet drains more efficiently. Traditional perforated pipe systems have a limited open area which can prevent the efficient evacuation of water against structural walls. SITEDRAIN HQ eliminates these problems with a specially designed core flange that allows sheet drain water to enter directly into the perimeter drain. The result is a highly cost effective system design that ensures your building is dry and secure.

| SITEDRAIN HQS is designed with the same engineered core flange for sheet drain connections but offers a perforated core designed for soil applications where water entry is required from both sides. |

1. The nonwoven fabric replaces the stone's function of water collection and allows water to pass freely into the drainage core. Prefabricated drains provide more than 70% of open surface area for water collection.
|
| |
|
2. The formed plastic core replaces the perforated pipe, transporting the collected water to designated exits.
