WrimcoDrainage Cell System provides a perfect Solution for sub-soil drainage application for creating successful Roof Garden, without any traditional problems associated with cracking or leakage. It provides a uniform surface as well as an internal void space for effective draining of excess water.It has a unique Diamond CUP structure which provides water retention for passive irrigation and helps building a perch water table in the above soil profile for the vegetation to flourish in prolonged dry periods. It is inert to soil borne chemicals and bacteria. The cells shallow and effective drainage profile helps landscapers to make use of mature plants on roof garden which needs soil depth and water retention properties.
High Summer temperatures can cause thermal expansion in concrete and can cause waterproofing to crack, Wrimco 30mm Drainage Cell system due to its unique design and void properties help this heat to escape and hence reduce the risk of cracking, enhancing building life. The added benefit of the Drainage Cell material is the high compressible loading it can withstand while maintaining its drainage. It is environmentally friendly and easy to install.
Very high compressive load carrying capacity of up to 140 tons/m2.
Very high lateral flow capacity.
Maintains actual void size for effective drainage after backfill & compaction.
Fit-in system easy to cut and comes in pre-clipped panels.
Low weight, only 3.2 kg/sqm compared to 250 kgs/sqm of gravel for the same effective drainage,-hence reduces deck loads.
Thin - reduces depth of cover and allows the use of mature planting in shallow conditions.
Holds and creates a perch water table, providing ideal moist conditions for plant growth.
Reduces hydrostatic forces upon sub-grade walls.
Easy to shop, store and install comes in pre-clipped panels.
Reduce the risk of waterproofing to crack due to thermal expansion in hot periods.

Horizontal
Drainage System:
Wrimco
30mm & 50mm Drainage Cell system provides perfect Horizontal Drainage which
is used to improve drainage and replace or reduce natural aggregate drainage
materials in horizontal applications such as Green Roofs podium and planters,
and subsoil drainage applications. It provides protection for waterproofing
systems as well as positive drainage in the minimum amount of space (elevation)
and weight, both critical elements in roof and deck applications. In planters,
planting soil is retained while excess water passes into the drainage core and
is then conveyed into the collection system. Drainage
plays a critical role in the design and construction of below grade
applications. Without proper drainage, groundwater seepage may cause
hydrostatic pressure and leakage, resulting in structural damage. Wrimco 30mm
& 50mm high strength Drainage Cell 95% internal void surface ratio provides
multi-directional flow design allows a continuous path for water discharge,
eliminating the potential for hydrostatic pressure build up. It allows water to
pass freely into the drainage core, where it is gravity fed into the drainage
collection system.
Vertical
Retaining Wall Drainage System:
Wrimco
Wall Panels & Logs are made up of high strength 30/50 mm Drainage Cells
wrapped in needle punched non woven Geotextile filter fabric. High
compressive strength and high flow rate through the Drainage Cells provides
effective drainage and protection of the waterproof membrane for foundation
walls and other underground structures. The integrated non-woven Geotextile
covering the Drainage Cells stops ingress of soil particles, and prevent
blocking of the drainage sheet, creating an effective void for reliable ventilation
and allows inflow and transport of water from surrounding soil. Panels also
provides additional cushioning and protection for the waterproofing,
eliminating the use of Protection boards.
Wrimco
Wall Panel system replaces the traditional drainage aggregate, and saves time
and cost. The lightweight, pre-clipped wrapped panels are quick and easy to
install, without the need of any heavy machinery. In most cases excavated
material is suitable for backfilling, provided its permeable and non cohesive.
Underdrains: (High
Groundwater Table)
Rainsmart
30mm & 50mm Drainage Cells are very commonly used as an underdrain, to
capture and discharge rising high ground water and eliminating any hydrostatic
pressure build-up. The
high load bearing capacity and a 95% internal void surface ratio makes it an
ideal solution for parking lots , roads, and building foundations affected by
high groundwater. Wrimco
Drainage Cell is also commonly used as a capillary break in saline environments
in Reclaimed land, Salt water rising through capillary action in root zones can
destroy gardens, void created by a layer of Wrimco Drainage Cell eliminates the
rising capillary action and protects the sweet soil and root zone.
Advantages:
High 95% void ratio, creates effective void for
drainage
High Compressive Strength.
Anti Clogging
Reduction of hydrostatic pressure situations on
retaining structures
Additional protection for waterproofing
Light weight and easy to handle Pre-wrapped Panels
No heavy Machinery needed for
Installation.
Geotextiles have a long history of use in filtration,
sub-soil drainage, separation layer and protection applications.
Wrimco Supplies nonwoven needle punched Hydrophilic
Geotextile which is polymer based products that are manufactured from a variety
of processes. Generally for sub-soil drainage needle punched non woven
Geotextile is most suitable type of Geotextile that should be selected for use.
The polymers offered are polypropylene or polyester.
Nonwoven geotextiles are manufactured from the extrusion
of fibres which are then laid down on a manufacturing "bed" and then
needle punched to entangle the fibres such that a dimensionally stable product
is formed. Some additional thermal treatment is then applied to further improve
the strength of the geotextile. Because of this manufacturing process non-woven
Geotextile are generally best used in applications of drainage, filtration and
protection.
