DRAINAGE OPTIONS
®
DELTA SUMPS & PUMPS
DELTA
When specifying a sealed cavity membrane system, full consideration must
be given to drainage, when installed below ground.
The concept of the drained cavity system is to collect and manage any
moisture which breaches the integrity of the structure by channelling,
collecting, and discharging such free water via a suitable evacuation point.
Channels, laid to falls, can discharge passively into a sump or be connected
to a drainage system but access for maintenance should be provided.
Access ports allow inspection and water jetting of channels, while sumps
have a sealed access cover which allows for annual maintenance checks to
be carried out, which are recommended.
If drainage has been installed, it should be flood tested before covering it up
to make sure the system works.
Delta offer a choice of sump+pump stations to fit the purpose, including
Ground, Surface, Foul Waste Water pumps as well as bespoke sumps.
Service agreements can be arranged through Delta and are maintained by
PPS Ltd.
Delta Sumps are fitted with a dual pump system and have up to three
110mm/160mm side inlets to take ground water, or grey water from
shower, laundry and sink waste via a modular drainage system.
DELTA® CHANNEL
®
DELTA AQUADUCT
DELTA
Delta Channel is a water collection conduit which is bedded into a preformed channel at
the floor/wall angle. Holes in the channel wall allows water to ingress at this point to drain
away to a sump or soak away. Access ports are available to allow maintenance and
inspection. The system is joined with a range of connectors.
Delta Aquaduct is a drainage channel which acts as a perimeter conduit bedded in at the
floor/wall angle. Where appropriate, it can be laid under the slab to take off ground water
to a sump or soak away, and reduce flotation pressures from bearing on the slab.
Delta Aquaduct is fully perforated for maximum performance, and incorporates an outer
geotextile filter to prevent particles from entering the channel.
The product comes on a roll 150m x 60mm diameter. It is also available in 100m x 100mm
dia rolls.
'FREE LIME' RISK
When new concrete forms the structure, to walls or particularly floors, there is a risk of
excess free lime leaching out during the curing process.When a cavity drainage system is
used in this type of application, a silicification pre-treatment of the concrete should be
used to prevent the risk of free lime build up, and blockage of the drainage cavity. Delta
Polysil-TG 500 is applied by spray for this purpose, and is available in 10kg drums.
BASEMENT PROTECTION
MAXXCONNECT TM
DELTA
If you've installed a cavity drained system internally, one of the main
design considerations is how are you going to manage the water
collection and discharge. This can be done passively into existing
drainage points, if available and appropriate.
However, the majority of projects require a collection sump + pump,
to automatically manage the evacuation of any water ingress. This
type of unit requires mains power to operate, so what can be done if
the power fails, and is coincident with high water ingress?
The PowerMaxx Battery backup can run up to 2x V3 groundwater
pumps without mains power for up to 4 days depending on the cycles
per hour and sits in standby for up to 3 weeks and is virtually inaudiable.
Peace of mind with the MaxxConnect™ family.
The family consists of 3 products, the main and most essential
being the AlertMaxx high level alarm to alert when there’s a
potetial fault or a service is required, the PowerMaxx battery
backup to keeppumps running during power cuts and the
MessageMaxx telemetry which has the ability to send alert
messages to up to 5 mobile phones and important data can
be retrieved remotely.
