CORE Drainage - Efficient Water Drainage Cells
CORE Drainage cells provide an efficient water drainage solution to a variety of applications such as:
- Driveway drainage, roads and highway edge drains
- Retaining wall, abutment drainage and basement drainage & waterproofing
- Roof gardens and green roofs
- Sports fields, golf courses and saturated ground drainage
The construction of the cells allow water to flow evenly across the surface, avoiding areas of water build up.
CORE Drainage board cells are made from recycled polypropylene and are extremely lightweight and strong.
When installed vertically and wrapped in a geotextile membrane they form a highly effective fin drain, incredibly thin and unobtrusive with immense water-flow capabilities.
WHY CHOOSE CORE DRAINAGE?
Vertifical Fin Drain for Driveways, Roads and Edge Drains
When using permeable wearing course such as CORE Drive and CORE Grass, permeable paving or macadam below the permeable wearing course will often become saturated with water, with the water flowing in the direction that has the least resistance.
If this happens to be in the direction of your building, you could end up with a wall becoming saturated with water that will cause damp issues.
CORE Drainage cells can effectively capture sub surface water and transport it away. This application us perfect fir areas where saturated ground meets an external wall of a basement room or a sloped driveway that descends towards a building.
CORE Drainage cells will help relieve the hydro-static pressure in the ground against retaining walls and stop the ground from becoming water logged. Excess water will also be removed to an are where it will not cause an issue e.g a purpose built soakaway or storage tank.
Vertical Fin Drain for Sports Fields & Saturated Ground
The permeable surface of the CORE Drainage fin drain is over 80% compared to the 5% of a conventional perforated pipe. Water is drawn from the soil at a faster rate. The drainage cells are wrapped in a permeable geotextile membrane in order to let the water in but keep the silt out. If the ground conditions are covered by a lot of stone, we recommend that you double wrap the cells to protect them from becoming clogged.
At only 25mm wide with a flow rate of over 5 litres per second, this system is the perfect retro fit for saturated ground providing effective sub surface water flow with minimal surface disruption, allowing rapid re use of the area.
The use of CORE Drainage incurs less imported fill cost and has an extremely fast install time with minimal disruption compared to traditional drainage methods
Vertical Fin Drain for Retaining Walls & Basements
Ground saturation will increase when using a permeable wearing course such as CORE Drive, permeable paving or permeable macadam. CORE Drainage cells can direct the excess water away from structural and retaining walls. CORE Drainage cells will help relieve the hydro-static pressure that also builds up.
Sub surface ground will often become saturated with the water that accumulates often flowing in the direction of the least resistance.
If this happens to be towards your building, the wall will become saturate, leading to structural and damp problems that can be very costly.
CORE Drainage cell offers a far cheaper alternative to prevent this from happening, at a fraction of the price of fixing it, if it was to occur.
Installation for Roof Gardens and Green Roofs
CORE Drainage cells are perfect for roof top gardens. Firstly, cover the existing roof with an impermeable membrane, interlock the cells and lay them directly onto the roof. Next, cover the cells with a permeable membrane which allows the water through whilst preventing the cells from becoming clogged with silt.
Soil can then be placed directly on top and planted. The increased water flow and high weight bearing properties of these compact modules allow for a greater soil depth than alternative methods, giving you a wider variety of plants to choose from when designing your garden.
CORE Drainage cells also retain enough moisture to provide ideal growing conditions when used to line the roof planters or raised beds ensuring only wanted excess water is removed. By placing the CORE Drainage cell in the way shown, it is possible to remove the drainage cell that is directly above the roof drain without having to detach it form the surround cells. This makes the roof drain easily accessible, which is helpful should you ever need drain access.
