Effective moisture protection for below grade structures.

Reliable moisture protection of subsurface structures is an indispensable imperative.

DELTA® Drainage Systems for Civil Engineering provide effective and durable solutions. For the entire life of the structure.

DELTA®-DRAIN - Horizontal Applications
Drainage and protection system for horizontal applications. Ideal for use under thin overlays with pavers, as well as in garden roof applications, i.e. extensive green roofs, where effective drainage is required.
more

DELTA®-DRAIN - Vertical Applications
Highly effective drainboard that adds protection to shallow depth foundation walls by controlling the flow of below grade water. Eliminates hydrostatic pressure against below-grade structures by providing a drainage path for water.
more

DELTA®-DRAIN 2000
This drainboard is designed to meet the requirements for light commercial applications and shallow depth foundations. It features high compressive strength, excellent drainage capacity and reliable long term performance.
more

DELTA®-DRAIN 6000
Heavy-duty drainboard, ideally suited for applications in underground areas such as foundation walls, lagging or caisson walls, and retaining walls where high compressive strength and water flow rates are required.
more

DELTA®-DRAIN 6200
DELTA®-DRAIN 6200 is a high-performance drainboard that features a tough polymeric sheet adhered to its back surface. The protection sheet prevents viscous flow and die cutting of soft liquid or sheet applied waterproofing products.
more

DELTA®-DRAIN 9000
The ultimate high strength, high performance drainboard ideally suited for demanding horizontal drainage applications in plaza deck, pavement, and split slab construction where high flow rates and ultimate compressive strength are required.
more

DELTA®-MS 20 - Vertical Underground Applications
DELTA®-MS 20 can be economically applied on vertical surfaces as "permanent formwork" between a shotcrete layer or diaphragm wall and the concrete structural wall. The shotcrete or diaphragm wall acts like a filter and keeps the seepage layer free from ground soil particles.
more

DELTA®-MS 20 - Horizontal Underground Applications
Its high drainage capacity enables DELTA®-MS 20 to meet all requirements for occurring water problems in horizontal underground constructions.
more

DELTA®-MS 20 - Tunnel Ceiling & Wall Application
Its high drainage capacity enables DELTA®-MS 20 to meet all requirements for occurring water problems on tunnel construction projects.
more

DELTA®-MS - B1 (flame retardant)
for Tunnel Ceiling & Wall Application
DELTA®-MS B1 is equipped with highly effective flame retardants. It meets the stringent requirements of DIN 4102, Class B1 and is therefore ideally suited for drainage applications in tunnel construction projects with specific fire hazard regulations.
more

DELTA®-MS 20 - Tunnel Bottom Application
Its high drainage capacity enables DELTA®-MS 20 to meet all requirements for occurring water problems on tunnel construction projects.
