Commercial retaining walls require proper drainage to reduce hydrostatic pressure. Native soil is comprised of multiple layers that determine the ability of the water to move through the soil. Low permeability soil layers can trap water against below grade structures. The force of water can compromise the wall, creating leaks and in extreme cases, structural failure.
Stone drains require extensive excavation and are not always practical or feasible.
Failure to design for proper drainage can result in increased material cost to handle increased load requirements or may require expensive repairs.
Prefabricated sheet, strip and combination drains work together as a complete drainage system to eliminate hydrostatic pressure against retaining walls by providing a secure flow channel from grade to footer. The molded core has a securely bonded filter fabric that allows water to freely pass while restricting soil particles.
The sheet drain is placed against the full surface area of the vertical wall and connects directly into the combination drain. Combination drains function as a perimeter drain and are designed to handle the high flow capacity of water collected by the sheet drains. The impervious core of both products provide protection to the structure during backfill and eliminates the need for a protection course. The result is a highly efficient, sustainable, cost effective system designed for long term performance.
is designed for retaining wall applications where moderate compressive strength and flow capacity are adequate. The core side is placed against the wall surface of the structure.

Series functions as a high-flow collection system for SITEDRAIN Sheet products. This patented design combines a low and high profile core with a unique core flange designed to connect directly to the sheet drain. Designed to collect and transport the high volumes of water collected by sheet drains, SITEDRAIN HQ is a performance driven, sustainable solution to ensure the most efficient
provides a value alternative to perforated pipe and stone drainage systems. It provides a significantly higher flow rate as well as increased ease of handling and installation.
SITEDRAIN HQ and Strip products eliminate weep holes by re-directing water to designated areas.
